The Mosaic office’s open office design seamlessly integrated spaces dedicated to concentration, teamwork, and innovative idea generation. Working closely with the client, the design team gained a deep understanding of the company’s mission, goals, and operational procedures. They adeptly incorporated various workspace layouts that fostered and harmonized with the critical elements conducive to enhancing productivity. Moreover, with the office’s early beginnings in mind, the design team strived to include adaptable features capable of evolving alongside the company’s expansion. The design encompassed numerous meeting and collaborative zones, open office seating, a staff pantry, and dedicated focus rooms.

Located on the second and third sub-cellars of the Lotte New York Palace, the parking garage serves all patrons and employees of the hotel. As the work took place during the COVID-19 pandemic, EDG was offered the rare opportunity to work in a completely unoccupied garage, allowing a $2 million repair project from document preparation to repair to be completed in just over four months.

Impact

EDG provided weekly 360° scanning services during the entirety of the project so the hotel owner could monitor project progress from overseas. Since the successful implementation of scanning technology at the Lotte New York Palace, EDG has continued to provide scanning services on other projects, offering clients the opportunity to “walk the job site” from the comfort and safety of their home or office.

Scope

EDG was crucial in providing interior design services for a substantial 25,000-square-foot office project. The process started by closely collaborating with the client to identify the most suitable space that aligns with their requirements. EDG visited multiple properties, produced preliminary plans to assess seating capacity, and did preliminary pricing exercises to understand project feasibility. Additionally, they liaised with the property owner to gain insights into the unique challenges associated with each space. Considering that the client was a trading company, the program encompassed a comprehensive range of areas, including office spaces, open offices to foster collaboration, dedicated collaborative spaces, a vibrant café, and a well-equipped food service kitchen. EDG’s involvement throughout the process ensured that the design explicitly catered to the client’s needs, resulting in a harmonious and functional workspace.

Scope

We initially performed a property analysis for this entire city block, from street-to-street and avenue-to-avenue, between Madison and Fifth Avenues. Our goal was to unlock the maximum value of the property by utilizing the maximum allowable floor area, repurposing existing space, and increase parking on the site. As a result, our work includes designing approximately 170,000 sq.ft. in total new floor area and renovating 48,000 sq.ft. as part of over 10 projects throughout the development site.

Approach

The owner previously retained two other consultants who determined only 20,000 sq.ft. of the remaining FAR could be used. We revisited the original zoning analysis performed on the existing site and found multiple locations available to construct approximately 170,000 sq.ft. of gross floor area. Our work also included navigating the Harlem-East Harlem Special Purpose District, as well as recent rezonings and the original zoning at construction. We looked at the site holistically, carefully examining the existing building’s operations, while considering the seamless integration of the proposed buildings. We also considered structural considerations for all proposed work.

Impact

Our high-level understanding of zoning and building design experience gives us the advantage of having a complete picture of a development site. For this project, we navigated a large number of zoning and code considerations, including subdividing the site. We de-risked dozens of potential issues on an incredibly complex site to make the development possible. As a result of our initial work finding ways to capture the full underutilized FAR, we are currently designing the reprogramming of 48,000 sq.ft. of ground floor spaces, including: retail, commercial and community facility space; a 60-car parking garage expansion; additional commercial/community facility space; the consolidation of lobbies to recapture floor area; as well as the design of a new 19-story residential tower.

Scope

The property extends block-to-block and avenue-to-avenue, with 280 units in two nearly-identical buildings. The existing buildings are situated off-center on the lot, creating an awkward 60-ft. rear yard. Site challenges included complicated zoning issues, a sloping site, parking constraints, as well as the impact of an addition on the existing structure. After seeing our success on another project in Queens, the client retained us to do an investigation of the site’s development potential. Two other architects had previously assessed the property and determined they could only build a small, 30-unit building on the corner of the lot.

Approach

With every project, we know there is a puzzle to solve and that anything is possible. We carefully navigate the Zoning and Building Code, which is often misunderstood, and involve the Department of Buildings in our analysis to ensure compliance. For this project, we obtained three “pre-considerations” from the Department of Buildings to clarify zoning issues that could later affect the project’s feasibility.

Impact

EDG planned a completely new structure where other consultants saw only a large backyard and an unsightly view of the back of a building. With our Zoning and Building Code expertise, we designed a compliant addition that spanned over 600 ft. in length. With two new building segments, our investigation enabled adding 180 units to the property. Ultimately over 150 units will be built. In addition to providing planning and architectural schematic documents, we are the project’s structural engineers and owner’s representative.

Scope

The project was for the property assessment and site planning of four zoning lots with existing buildings on the waterfront in Long Island City, Queens. The subject property extends street-to-street, encompassing two corners, and is an Inclusionary Housing site. Massing and 3D renderings were prepared. We are currently in schematic design for the new building.

Approach

The size of the site gave us some flexibility, however the existing buildings on the site created constraints. We needed to be sure that our proposed lot merger didn’t create a new non-conformance with yards or distances between buildings. The property also had a portion of the site with a Landmarks designation, and although we were able to work the design around the boundaries, we worked with Landmarks to ensure compliance.

Impact

Ultimately, we determined that the site had approximately 200,000 sq. ft. available and usable, far greater than the owner’s original estimate of 60,000 sq. ft., provided by their previous architect. Yards and courts were carefully navigated to maximize the use of floor area on the site, while providing maximum and minimum building dimensions that lend well to the future design of the apartments. The site is in a flood zone, so residential occupancy is not permitted at ground floor, and the site is not on a retail corridor, so we dug in deeper for ground floor use. We utilized the existing occupancy at the ground floor, looking to lower the use from existing manufacturing to public parking, which will be of great benefit with the new ferry opening nearby.

Scope

At the heart of Manhattan’s east side, the 36-story residential tower in Kips Bay offers unbeatable comfort and convenience. Interested in maximizing the value of existing spaces, real estate agency Kibel engaged EDG to renovate approximately 20,000 sq. ft. of the property’s shared roof and ground plaza areas. EDG’s architectural and engineering team collaborated on extensive planning, design, and construction administration to reinvigorate the aesthetics and functionality at 300 East 34th Street.

Approach

EDG navigated complicated building codes, conducted structural analysis, and explored possibilities to re-purpose existing components to achieve a cohesive, welcoming design. On the ground plaza, the team introduced carefully considered geometry and materials to existing site elements. On the roof, the team retrofit a previously inaccessible space by extending elevators, transforming mechanical rooms into amenity space, and reviewing the impact of increased loading of the existing roof.

Impact

With meticulously planned architectural and structural moves, EDG unlocked the potential of the residential tower’s community spaces. The building’s 300+ residents now return home through a distinct landmark piazza, where lively congregation fosters a rich civic space. The plan enhances accessibility, visibility, and capacity – while maximizing retail potential and developing a signature design on the ground plane. Thirty-six floors above, residents enjoy an exquisitely curated 360° panorama of Manhattan’s skyline, accompanied by a pristine pool, lush gardens and pergolas.

Testimonial

As the main broker for the North Shore Towers and a resident myself, I’m grateful for the work EDG did on the building façades. Throughout the project, even when they were working on my own high-rise terrace, the team was conscientious, timely, and professional. The restored balconies and facades look great and better represent the ‘luxury community’ essence of our residences.

Scope

Growing VANS’ “Off-The-Wall” legacy, the leader in footwear and skateboarding sought to open a new store in Herald Square. Located less than 100 yards away from Manhattan’s busiest intersection, the existing four-story, 100+ year old structure required an extensive gut renovation. RGLA engaged EDG for structural design services, including the creation of 20-ft. high ceilings above the retail space, a new elevator installation rising from the basement through fourth floor, a new stairwell installation connecting the first and second floor, and a refreshed storefront conveying the VANS brand.

Approach

The existing structure was a complicated amalgam of previous renovation campaigns, which became an unwieldy patchwork of century-old building materials and techniques mixed with modern construction. With deep knowledge of both historic and modern construction, EDG analyzed the conditions and employed best practices to bring the project vision to fruition. To create the double-height ceilings, EDG removed the third floor in its entirety – a task which required the removal of an exterior masonry wall and load transfer toto a new steel support structure hidden within the walls and ceiling of the second floor below.

Impact

Given the location’s prominence, it was imperative to open the retail space prior to Black Friday. By engaging modern structural analysis software, EDG was able to immediately update designs based on architectural revisions and in-field conditions. Providing constant onsite representation throughout the tight construction schedule, the EDG team was responsive to all unexpected conditions and updates. From initial concept through close out, the entire project was completed in less than six months, with the store opening before Thanksgiving. The exciting new space transformed a complex existing structure into an immersive customer experience center, expanding VANS’ street culture influence in the heart of Manhattan.

Scope

This project involved the creation of a high-end retail space on the high-end street – Madison Avenue. We performed an extensive gut renovation, removing three floors of the structure, and replacing only two, reconfiguring egress to provide more efficient exits, while opening up the floor plan to better suit retail operations, and installing a new elevator. While handling the architectural design, renderings, structural engineering, and filings, we needed to navigate historical code, Landmarks, as well as new building code requirements due to the alterations.

Approach

The result was a first-floor level with the ground (prior ground floor was sunken, making retail access challenging) and second floor located in a position that provided expansive heights on these two floors 100 ft. deep. The design needed to be contextual in color palette, unaggressive in its stature, and its inviting in nature.

Impact

The finished ground floor, with ceiling heights of 17 ft. clear – nearly a perfect square height to width, with a storefront appearing as a single panel of glass, creates the feeling of a “windowless” shopping experience between you and products inside. The design concept transcends the brand, with any retailer projecting their product, here. With barely a hint of the physical separation, the store can be referenced from the street and now the street becomes an extension of the store.

Scope

Having seen what we could do on other projects on the property, the client retained us to review the development potential of the site. A 13-story building currently exists on the site. The building is the shape of an E with a large yard, which forms the shape of a C, not visible from the street.

Approach

This project is near the top of the list of complicated projects, which we have grown to specialize in. To the surprise of the client, we found that with improvement bonuses, up to 235,589 sq. ft. could be added to the site. This resulted in an additional 25 stories, for a total tower height of 37 stories. The new structure partially penetrates the three existing floors of retail and two cellars, requiring extensive coordination. In addition, a new separate entrance for the tower lobby needed to be provided.

Impact

Floor area bonuses require special permits, tied to relocation of subway entrances and other improvements, which needed to be assessed. Egress for the new tower was also carefully navigated through the existing egress stair towers. For wind and seismic loading, we designed an exterior structural support system which minimized the impact on the interior of the existing structure. Upon completion of our work, we worked with the client and CMs to prepare preliminary cost estimates.

Scope

The Pavilion bar and nightclub is an icon of Fire Island Pines, one of New York’s favorite summertime getaways since the 1950s. In 2011, a devastating fire destroyed the original Pavilion, and EDG was brought on to serve as the structural engineer for the new 8,000-sq.ft. structure. We worked alongside award-winning architectural designer HWKN who crafted a dramatic design to honor the legendary site.

Approach

With the building’s three-dimensional surfaces and angular form, timber construction proved more challenging than typical construction methods, but our experience designing with a wide range of materials allowed us to successfully develop a unique timber framing system. We also worked with local contractors to determine best practices and preferred materials for the area during the design phase. The mass timber structure is comprised almost entirely of renewable wood resources, from the timber piles and pile caps, to the floors, roof, walls, and all other exposed surfaces.

Impact

It includes a terrace, outdoor bar and lounge, indoor bar, and dance floor with bleachers at each end, as well as a gym and three retail spaces. Although the venue regularly serves as a club and hosts parties at night, the space is also used for performances, as an art gallery, and even a wedding chapel in the daytime. To celebrate the Pines’ beloved beach culture, the design incorporates exposed-wood surfaces and structural materials throughout, creating the perfect beach backdrop for any event.

Scope

This three-story building with a cellar is located in Harlem, NY. The construction is brick and cast iron, supported on pile foundations. EDG performed a feasibility study for the addition of one to three stories on the existing structure as well as the replacement of the existing structure with a new building. Our work included planning, architectural design, structural engineering, geotechnical engineering and cost-estimating. Previously, we were the architects, engineers and project managers for the 9,000-sq.ft. Red Rooster restaurant and event hall, which span two levels of the building.

Approach

Because the building was occupied during design, we took the least invasive approach for the foundation test pits and probes. We looked to configure the addition so that it was supported by the vertical and lateral supports of the existing building structure. Designing the addition to this 80-year-old structure required a deep understanding of historical construction types.

Impact

Once we determined that reinforcement was required, we designed the addition so only one line of columns required reinforcement and so the ground floor restaurant could continue to operate during construction. We then outlined the requirements for the addition to determine costs for project feasibility.

Scope

EDG was hired to repair the 3rd, 4th and roof levels of this parking garage, located in White Plains, NY. We designed the restoration of the precast structure, including the façade. The previous owner had neglected the structure, leaving the three levels in extreme disrepair. In some areas, water would pour in from the ceiling, obstructing vehicular traffic.

Approach

By surveying and probing the structure, classifying work into critical and non-critical categories, and reviewing long-term preventative maintenance opportunities, we determined potential vs. actual costs and offered repair options through value engineering. We also provided the owner with design options for the future parking expansion.

Impact

The project was carefully phased, so critical areas were addressed first. We successfully evaluated alternatives to add value to the structure, including potential expansion of the parking garage. Note: During the course of the project, the garage was acquired and demolished by the City of White Plains.

Scope

Concordia College is a private liberal arts school located in Bronxville. The school struggled for a few years to provide additional parking on their campus, because local authorities were concerned about potential traffic and environmental impacts. The client approached us to design parking layout options that would maximize the number of new spaces while minimizing impacts on neighboring properties and landscape. With our designs, Concordia was able to meet with the Mayor and local authorities to discuss potential impacts and gauge political support for the project before navigating the approvals process with the local planning board.

Approach

EDG surveyed the site to determine existing conditions, opportunities and constraints. Work included review of vehicular ingress, egress and internal traffic flow, as well as preparation of schematic plans to demonstrate parking capacity for various layout options. We prepared detailed plans for the chosen layout, including tree replacement, lighting, and stormwater design calculations.

Impact

We increased the parking capacity of the site by over 30% with less than a 20% increase in impervious areas and ultimately provided a more cost-effective solution with a greater parking capacity than offered by other consultants. We also helped the client manage the political side of the approvals process.

Scope

Design of a new 12-story, mixed-use building, approximately 140,000 sq. ft. in Queens, NY. The apartment building includes a community facility and parking garage below. EDG provided engineering design, specifications, and construction observation services for the project.

Approach

Lack of communication is often the cause of failure on projects, so we put a lot of focus on it here. One example of this is engaging the construction manager as early as possible for a constructability review to confirm that the project design is compatible with the means and methods of the intended construction, as well as to discuss the feasibility of all details. We also review potential complications that we’ve experienced on past projects, as they tend to repeat themselves.

Impact

We always do our part to improve the project team’s communication because it saves our clients significant amounts of time and money. Our efforts prevent costly redesigns which are often incurred in merging design and construction requirements.

Scope

Located on the Hudson River, this pier complex is the largest in the city. It includes an enormous recreation center, acres of field space, approximately 2,200 long-term parking spaces (the largest parking facility in Manhattan), and the offices of Hudson River Park Trust, who operate Hudson River Park and 36 piers. The scope of work included the assessment of the existing deck conditions and design of the rehabilitation of the 40+ year old pier, including the complete replacement of the top slab deck and waterproofing.

Approach

Given the large square footage of the complex, every detail can have a significant cost impact, so we looked carefully at the key cost variables. Many repair options were explored to obtain the optimal solution. The client required that the roof deck be made watertight for years to come, so we carefully evaluated leading waterproofing systems to find one that fit the needs of existing and future conditions. As the largest revenue generator for the Hudson River Park Trust, continued operation during construction was extremely important and phasing had to be carefully planned.

Impact

We prepared cost estimates for the work at every stage of design. The project not only came in just below our budget estimate, but below the contracted construction cost. The success of the first phase of the project was a team effort made by all parties, including Trust’s team and the contractor. EDG initially set out to understand everything about the existing conditions in the scope of work. This high level of due diligence paid off, and no design changes were required. All phases of design work were completed early or on-time, which was essential for the pier to continue serving both the community and the Trust’s operations.

Scope

In 2010 and 2015, the New York City Housing Authority issued a bid for the restoration design of their developments’ façades and roofs. Dozens of firms in the tri-state area responded to these bids. EDG was one of eight firms selected to receive a five-year contract for the design of the envelope work for the 2,600 buildings. Our work includes preparing Local Law 11 façade condition reports, required by the NYC Department of Buildings, for over 200 of NYCHA’s buildings. We are also responsible for the design and specification of associated repairs and necessary roof replacement at the developments.

Approach

Due diligence is always our first step, as we carefully review all available records and visit the sites to determine conditions that affect our work. Having a clear picture of prior work on the developments allowed us to properly plan our approach. We put in the time to understand the needs of the Housing Authority, including CAD and report standards. Most importantly, we only took on work we could handle.

Impact

Our office has not missed any of the numerous deadlines set by the Housing Authority, many of which have required a very tight schedule. Running a project of this magnitude is an enormous undertaking for a government agency, and we understand how crucial it is that we meet any required deadlines. Our work in performing the repairs will help ensure the safety of the occupants and the longevity of the buildings.

Scope

The H-bridge is a two-way vehicle and pedestrian bridge that crosses over the Metro North Hudson Line in Tarrytown, NY. It is nearly half a mile of elevated roadway deck and sidewalk. The steel members, concrete roadway, expansion joints, sidewalks and drains required rehabilitation. Extensive deterioration was found at steel columns and girders that required shoring and immediate repair.

Approach

EDG quickly opened up communication with the Village of Tarrytown and the Metro North Railroad to obtain a history of reports and construction to the bridge and roadway. They were kept informed of the status of all work to prevent any delays later in the project. Our knowledge of material science and concrete and steel deterioration played a key role. Severely deteriorated steel was immediately identified and testing was performed on all steel showing evidence of deterioration.

Impact

In consideration of budget expenses, we assess priority phasing on nearly all of our restoration projects. With an experienced eye, we identify immediate repairs, short-term repairs, and any long-term maintenance work required. Ultimately, over six million dollars of restoration work will be required, which will be performed over several years to work within the budget of the Village.

Scope

We were invited to submit a proposal for the design of a new, state-of-the-art cybercrimes lab with support spaces for the District Attorney’s Office. Our work included planning, design, specification, cost-estimating, filing, bidding and construction administration services for the 21,000-square-foot project.

Approach

EDG’s project management division is well known for facilitating projects requiring specialty design. For this project, we brought in McClaren Wilson & Lawrie, Inc., an architecture and planning firm specializing in laboratory design. We provided seamless communication and handled the standard complications, while navigating the filing process.

Impact

Drawing from dozens of previous lab designs, MWL created an effective space that met all the goals of the District Attorney’s Office and achieved certification with the American Society of Crime Laboratory Directors. Our ability to find and work with the right specialists allows us to take on any project requiring extensive experience and avoid time-consuming learning curves.

Scope

This eight-level underground parking garage with slab-on-steel framing services the 57-story high-rise building above it and the surrounding area, which includes Madison Square Garden. EDG was hired to conduct extensive concrete slab and steel beam repair and replacement, as well as waterproofing membrane repair and installation throughout.

Approach

To keep the garage in operation during construction, we carefully phased repair areas and split them up into 14 sections. The waterproofing membrane application was performed in seven phases.

Impact

We closely coordinated between the building owner, garage tenant and contractor to ensure garage operations were uninterrupted during the repair effort and to maintain the safety of the garage users and operators.

Scope

The 33-story, 609-unit apartment building occupies half of a city block with approximately 300,000 sq. ft. of façade. EDG was retained for emergency inspections at 30 Lincoln Plaza when previous repairs at the concrete eyebrows began to fail. The subsequent scope of work included façade inspections, preparation of repair documents, construction administration, and Local Law 11 reporting.

Approach

Emergency conditions required that we mobilize and assess the concerns immediately, but a complicated geometry proved challenging for inspections. One of the major obstacles of facade restoration is assessing the entire facade with only limited access. As a result, we do much of our work from the ground, using high-powered, image-stabilizing binoculars and telescope equipment. This technique provides accuracy, eliminating the need to perform scaffold drops on all facades prior to construction. Our “hands-on” inspections are performed later to get a better idea of deterioration. During construction, we have up-close access to the entire facade area.

Impact

The ability to mobilize a full team quickly allowed EDG to stabilize the concerns with minimal disruption to tenants. We phased subsequent repair work, in order of importance, around the needs of the client.

Scope

This 500-unit condominium includes a plaza and parking lot above a parking garage. The garage was neglected by the previous owner and left in extreme disrepair. EDG’s work included parking garage restoration, plaza repairs and redesign, parking lot repairs, parking lot extension and façade repairs.

Approach

Initially brought in by a tenant who was on the opposing side of the ownership, the client quickly learned that we had a solid understanding of the work. We were hired by both parties to jointly handle the project. They were shocked by the estimate provided by their former consultant, so we looked to determine all the unknowns, reducing potential costs to actual costs, and began value-engineering repair options.

Impact

With minimal assessment and two probes, we significantly reduced contingencies and worked to evaluate alternatives that would add value to the building, including expanding parking as part of the repairs. EDG ultimately completed more work for 25% of the cost the client had been provided by their former consultant. We also carefully phased the work so the worst areas were handled first. The parking lot expansion provided significant value to the client.

Scope

Located in Lower Manhattan, this 23-story, Cass Gilbert landmark was gut renovated, converting the historic office tower into a luxury apartment building. As part of the renovation, EDG performed architectural design and structural engineering services for the enlargement of an existing amenity space within the central portion of the building.

Approach

Renovating a historic building is very challenging, given many unknown conditions. Our client also requested a modern design which complemented the building’s original aesthetic. To meet these challenges, we opened up masonry walls on two sides of the space and cut back existing non-structural piers, creating new connections to adjacent rooms. We then designed a new ceiling system and lighting layout to unify all of the spaces visually. This architectural strategy allowed for an integrated design, balancing both modern and historic elements.

Impact

Using an adjacent one-bedroom apartment, the renovation increased the indoor amenity space by more than 700 sq. ft. At the same time, our design revitalized the 500-sq.ft. courtyard and created a more visual and physical connection between all indoor and outdoor common areas. The result is an expansive, contemporary amenity space, including a fitness center, yoga studio, private dining / event space, lounges, meeting spaces and landscaped terrace.

Scope

This historical building occupies the full footprint of a three-acre lot with an interior courtyard of over an acre. The five-story building includes approximately 250,000 sq. ft. of residential housing with commercial space on the ground floor. Due to the extensive deterioration of the brick and decorative stone elements, 3,000 linear feet of sidewalk shed was erected at its perimeter and walkways to perform the work. The restoration scope included brick and lintel repair, as well as parapet and roof replacement.

Approach

We conducted thorough inspections and assessed the full scope of all required building envelope repairs. We prepared overall construction cost estimates and phasing plans in order for the client to budget and plan. During the construction administration phase, we assisted with bidding out the work to contractors and performed all of the quality control inspections.

Impact

Due to the massive footprint and presence of the property, phasing of the project was crucial. The critical areas requiring repair were completed first, so the adjacent sidewalk bridging could be removed, ensuring minimal impact on both the commercial and residential tenants. The client also wished to restore the original building aesthetic, which was achieved by replacing the deteriorated ornamental stones and motifs with new cast-stone-veneer decorative elements.

Scope

This project included the restoration of a 120,000-sq.ft. parking garage structure and a resident plaza level with a pool, servicing a 300-unit apartment building. The structure required extensive repairs throughout, including slabs, steel beams and girder reinforcement to restore the structural capacity.

Approach

EDG was hired as design engineers and architects after initial cost estimates from less experienced firms, showed excess work and an over-estimated construction cost estimate. We were responsible for the concrete slab and steel framing rehabilitation, plaza level waterproofing (80,000 sq. ft. with topping slab construction), green roof installation, pool deck alterations, and ADA accessibility.

Impact

The repair work was completed on schedule and at 35% of the cost estimate provided by other consultants. We planned the work to be performed in eight phases so the garage could remain operational during construction. The 13,800-sq.ft. green roof transformed the previously unutilized plaza area into a beautifully landscaped amenity for building residents.

Scope

The Helmsley Hotels range from 16 to 40 stories with exterior façade construction varying from brick and stone masonry to glass curtain wall. For several Helmsley locations, prior to their recent sale, we have performed façade condition reports (including Local Law 11 reporting), design services for façade repairs, parking garage repairs below the hotel, plaza repairs, roof repairs, as well as interior architectural alterations.

Approach

As a result of the New York City Local Law 11 façade inspections, EDG designed extensive façade repairs to the structures as part of a maintenance program developed for the Helmsley Organization. For the associated façade repairs, we identified scaffold locations, coordinated riggers, identified all required repair locations and prepared all construction documents for contractors to place bids.

Impact

We worked directly with the Helmsley’s management staff, providing cost estimates and schedules to the client for budgeting purposes. With careful planning, all work was completed on time and within our estimated cost budget range. For all of the projects, we effectively managed the process, including the filing of the work with the Department of Buildings. We start filings very early in the process and understand the potential pitfalls of the Department of Buildings, allowing us to shorten the average filing period considerably.

Scope

EDG provides engineering and architectural services for many parking operators, including Icon Parking, Garage Management, Champion, Imperial and Edison Parking. Icon Parking alone has over 200 parking facilities in New York City, with over 5.5 million sq. ft. of space. More than most, they understand economies of scale in construction and turn to EDG to design cost-effective repairs, renovations and new facilities.

Our services provided to parking operators include condition surveys and concrete testing, condition evaluation, construction documents for repairs, cost estimating, bidding, construction administration, and site observation. The garages have varying types of construction, such as brick masonry, cast-in-place concrete, precast, post-tension and steel frame, and are either free standing structures or located within residential towers.

Approach

Parking garages in NYC experience heavy traffic, causing water infiltration and bringing in high levels of corrosive elements, such as salts. These result in a constant need for physical condition assessments and repairs. For busy, 24-hour parking garages, we phase the work when possible to maintain operations during construction. We achieve this by thoroughly understanding the restoration work, carefully planning, and working with the contractor to ensure proper site safety.

Impact

With our extensive portfolio of garage repairs and designs, we have determined the most cost-effective solutions for a wide variety of projects. We have also established assessment techniques proven to accurately define budgets.

Scope

EDG was selected for the façade restoration and roof waterproofing program for the Manor, which began in 2008. This historic resort condominium hotel is the largest and tallest building in Montauk. It was built in 1926 by Carl G. Fisher and is a four-story, 200-room hotel in the Tudor Revival style. The building is exposed to extreme weather conditions due to its location on the Long Island Sound, where salt water from the ocean rapidly accelerates the deterioration of the façade and roof.

Approach

Investigation is always the first step to a successful restoration project. This includes performing careful due diligence to obtain all of the available information on the construction of the façade as well as the history of repairs. If we don’t have a clear picture, we probe prior to or during construction to determine the conditions. Proper repairs and waterproofing can only be designed when there is a thorough understanding of the existing construction.

Impact

We worked closely with the contractor for repairs so there were no surprises in material selection or cost, which was essential for performing the work within budget. Our experts are trained to work with contractors and collect feedback to ensure constructability. We continue to provide façade repair design and detailing for dozens of unique façade conditions, keeping the Manor free of leaks and maintaining the longevity of the Landmark.

Scope

The Metropolitan tower is an 80-story residential building in Manhattan. The existing roof was a concrete flat slab and topping slab for a window washing raceway. The hot-applied bitumen roofing had reached its usable life span and was leaking throughout. The scope of work included the investigation of the reported roof leaks, which ultimately led to the replacement of the topping slab and waterproofing membrane.

Approach

This was one of our most challenging roof replacement projects due to the building height and the topping slab, which made assessment of the roof membrane difficult. Proper design cannot be achieved by making assumptions, so we probed the roof to determine the cause and extent of the leaks. Through the probes, we discovered an improper pitch of the existing roof deck, which resulted in leaks at the perimeter.

Impact

With our understanding of the various types of waterproofing and by identifying all of the roofing requirements, our team selected the best membrane for the topping slab condition on this project. We then coordinated with a window washing rig consultant to ensure the replacement was performed correctly. For a complex project like this, we make sure that all parties, including the building management, designers, waterproofing manufacturer, window washing rig consultant, and contractor, work closely together for a successful project.

Scope

Winthrop is a 591-bed university hospital located on Long Island in Mineola, NY. Since 2004, this project has consisted of maintenance and restoration for five multi-story parking garages and three surface parking lots accommodating 3,500 vehicles. Each garage maintains a different building system, including steel frame, cast-in-place concrete, open-web joists, precast double tees and waffle slab construction. Work has included full and partial depth slab repairs, façade restoration, steel repairs, painting, control and expansion joint repairs, waterproofing, lighting system replacement, and reconfiguration of surface parking lots to increase capacity.

.

Approach

For this project, EDG provided structural analysis, condition survey and testing, design, bidding, construction administration, and job site supervision services. Investigation is always the first step to a successful project. This includes performing careful due diligence to obtain all of the available information about construction and repair history. By understanding every aspect of the project, we were able to provide considerable space, time and cost-saving solutions.

Impact

Value is at the center of everything we do, so we worked closely with the contractor for repairs. As a result, there were no surprises in material selection or cost, which was essential for performing the work within budget. Our experts are trained to work with contractors and collect their feedback, ensuring constructability.

Scope

A section of brick wall, approximately 60 ft. long and 30 ft. high, had collapsed onto the city sidewalk. Fortunately, no one was injured in the collapse. EDG immediately responded to a call from the building’s management and was one of the first parties on site. Emergency response included coordinating sidewalk protection, assessment and reporting of the cause of the collapse, investigation into the remainder of the wall, and design of the remediation program.

Approach

We worked integrally with the Commissioner of the NYC Department of Buildings and his team to investigate and determine the cause of the collapse. A report of our investigation was submitted within 24 hours and reviewed and approved by the Commissioner’s office.

Impact

Our investigation findings indicated extensive bowing and underlying deterioration of wall ties. Water had infiltrated the parapet coping and façade expansion joints, and there was improper drainage of the face brick. We performed an extensive investigation of the remaining walls to determine if any other wall sections were at risk of collapse. We then designed cost-effective remediation work to avoid reconstruction of the full length of the wall.

Scope

The building is an 18-story residential tower with a two-level parking garage below. The garage below this existing tower hadn’t received maintenance in a long time and was in extreme disrepair. EDG developed an extensive repair program and performed a feasibility study to determine if it was possible to replace one of the elevators with a vehicular ramp for faster access for the garage operator.

Approach

Our client had already had some design work performed and received bids from contractors prior to our involvement. They were given our name from a reference because of our experience as value-engineering specialists. We reassessed, looking to find the best repair method and products for the project. This often involves big-picture assessments, such as weighing the cost of full replacement against the cost of patch-work. For the new ramp, we made use of our surveying technology and understanding of building engineering, and worked within inches to provide the ramp access.

Impact

We determined that the most cost-effective repair would be to replace the entire topside of the concrete slab, as opposed to a patch-style repair. Due to the volume of patch repairs that would be required, including the joint work, and the individual prep and piece-work, this replacement was a better repair and produced savings of nearly $400,000. With the ramp installation, we increased the value of the space to this operator significantly for minimal cost, providing a return on investment in a year and a half. Weighing cost vs. value is at the center of everything we do. All work, including the ramp and sidewalk waterproofing issues, was performed for the same amount as the original contractors bid for just the patch repair.

Scope

Located on First Avenue in the Upper East Side, this 32-story building has a high visibility podium set back from the street on three sides. EDG was asked to perform both structural and architectural services in updating the aging brick façade. Our intent was to replace the façade and weathered storefront with a contemporary and timeless solution, using materials that complement the remaining building and upper tower.

Approach

Peeling back the original façade was a challenge, as there were a host of structural remediation issues which needed to be addressed before we could proceed with a new finish. With our years of experience in restoration and structural engineering, we addressed the issues and designed a new façade with a smooth stucco and limestone finish to enhance the existing building materials. We also designed a structurally-siliconed curtainwall system for the storefront, which provides a clean ribbon of glass for the retail tenants.

Impact

The new façade enlivens a very active corner in a high-density district and adds a new layer of elegance to the structure. The restoration and revitalization of the 160 ft. of façade provide a new backdrop for the building’s occupants and surrounding neighborhood, enriching the plaza and promenade experience for residents, pedestrians and shoppers along the retail edge.

Scope

For this project, we worked with award-winning architectural designer, Steve Blatz. We performed the structural design for the gut renovation of a 6,000-square-foot apartment and a 5,000-square-foot addition of vegetative green roof space and landscaped roof decks. We investigated the existing structure for the remediation of construction defects and managed legal work associated with the penthouse addition and structural support of the green roof and roof decks.

Approach

After finding evidence of issues with the existing construction, we performed probes to identify the defects. Had we waited to investigate the structure, like many consultants do, we would have needed to completely redesign the project during construction, halting work and increasing the budget. This project included extensive interior alterations, where structural work involved a new interior courtyard, interior column removals, and reinforcement of existing structural elements. The roof decks were required to be independently supported so that loading was not transferred to the cast iron frame.

Impact

All of the construction defects were handled without having to demolish any of the existing structure, which saved hundreds of thousands of dollars. All new work was carefully designed so the existing cast iron framing was not used as structural support, and apartments below were not affected. The contractor for the project was impressed by EDG’s communication with them, as well as our focus on constructability, and has since recommended us on several projects.

Scope

Located in Chelsea, near the West Side Highway, this four-story building was on the market with great development potential. The client retained EDG to provided zoning and building code analysis, egress, architectural design, and structural analysis for potential future expansion.

Approach

We performed due diligence to create a full picture of the property and the existing building. We reviewed records from the Department of Buildings, including violation history, occupancy records, and previous filings. All of this information can greatly affect the value of the property. We then carefully reviewed the buildable floor area to determine the full development potential of the site.

Impact

With our extensive experience in practical cost estimating, we produced multiple development scenarios, including base repairs, an addition, demolition and reconstruction. In all options, we navigated complicated zoning and building code to fully utilize the site and deliver a much larger building. Ultimately, we gave the client a complete understanding of the existing property value and potential.

Scope

Located on the Upper West Side of Manhattan, this Landmark residential building is five stories high and has a cellar. EDG performed architectural design and structural engineering services for this gut renovation project. Searching for additional property value, we reviewed possible development scenarios, including recapturing unused floor area and the conversion to high-end residential apartments with an elevator. Ultimately, the renovation of all apartments was performed, recreational space was added to the cellar, and façade repairs were performed on the Landmark façade.

Approach

Renovating an existing building can be very challenging, given the unknown conditions behind walls and within ceilings and floors. A proper probe plan must be developed to assess the existing conditions, pinning down the costs, and avoiding changes during construction. The right contractors who have extensive experience in this type of work are required.

Impact

In addition to the full renovation of all apartments, we worked through all of the design issues to create two large recreation rooms in the cellar. We lowered the cellar floor a foot and a half to a ceiling height of 8 ft., greatly increasing the value of the ground floor units. Due to the renovations, the client’s return on investment is anticipated within two years.

Scope

The Victoria’s Secret retail store in Herald Square recently expanded their ground floor space by 30,000 sq. ft., taking over the entire basement and cellar floor as well as the fourth and fifth floors of the building. As part of the alteration, we designed the renovation to the existing floors, portions of the sidewalk vault space, and the fourth and fifth floors for conversion to storage, requiring a floor load increase. The project also included a sky bridge in the building’s courtyard on the fourth and fifth floors, which required façade alterations.

Approach

Prior to EDG’s involvement, another firm designed a repair to the 100-year-old basement for a new retail space. After reviewing the report and plans, we conducted our own assessment, performing probes and a historical review of the structure, to determine the Building Code construction requirements when the building was constructed in 1909. Prior to even probing the structure, we determined that it had significant additional capacity based on its original design.

Impact

Probes confirmed our expectations; the basement was constructed of very heavy steel and exhibited minimal deterioration. Savings over the original estimates were about 1 million dollars and the work was completed in a fraction of the time, so the store could open earlier than anticipated. Our assessment of the existing construction conditions also allowed for a larger sky bridge for the same cost. This project reflects our commitment to ensuring our clients always receive the most value for their money.

Scope

Kidville is a national Daycare and Learning Center. EDG performed engineering, code and restoration work for three Kidville locations, including gut renovations, new elevators and stairs, extensive alterations, a new mezzanine, a building addition, and a full replacement of a Landmark façade.

Approach

In our initial project meeting, we performed value engineering to reduce the need for additional pile foundations, which would have delayed the schedule and brought the project significantly over budget.

Impact

We use smart design to save our clients money; not all consultants are able to provide that service. Prior to our involvement, an extensive foundation system of piles had been designed. After careful analysis, our value engineering deemed the system unnecessary, saving an estimated $500,000. Our cost-saving solution was the demolition of a heavy brick masonry ground floor, which was replaced by a lightweight wood floor. This allowed for an addition to the building without any foundation reinforcement.

Scope

To celebrate the Year of Italian Culture in the U.S., world-renowned designer Antonio Pio Saracino was commissioned to create a permanent public art project and a symbol of Italy. His work, “The Guardians: Hero and Superhero” stand proudly in the plaza at Three Bryant Park. We assisted friend and fellow architect Saracino in the structural design of the sculptures, pro-bono. The statues are each 13 ft. tall; one is constructed of danby marble and the other of mirror-polished stainless steel.

Approach

While we have designed many structures, including sculptures, this project was extremely unique. Saracino intended the many individual pieces (approximately 125) to appear disconnected. With all elements exposed to view, the structural supports could not be easily hidden, so we focused our attention on the assembly method.

Impact

EDG met the challenge by designing thin support rods and hiding welds with stainless steel covers. We even assessed and reinforced the sculptures for high wind and seismic-induced movement. With proper planning and a diligent team, we met the advanced deadline for installation and achieved the floating appearance Saracino designed.

Scope

We would love to take credit for this beautiful dealership and the beautiful cars, but that’s not what we do. What we do is make sure that money is not wasted on base construction and structure, so the client has enough money left in the budget for a stunning showroom. We were the structural engineers for this project, responsible for the expansion and extensive alterations to the dealership, including a new ramp for access to the second level, rooftop parking storage, column and bearing wall removals, and alterations for a new architectural façade.

Approach

With extensive experience in dealership and parking garage design, EDG has a strong understanding of vehicle storage space requirements and floor loading needs. Whether for new construction or an alteration, we look to design cost effective solutions by exploring all options for the structure. We review all structural aspects of the project and offer more cost effective alternatives to the architectural design. We value-engineer by ensuring the right approach is taken and by understanding the existing construction to best accommodate the alteration.

Impact

We redesigned the ramp in a more convenient and effective location, saving over $300,000 in unnecessary removals and relocation. This also gained valuable space for the showroom area and the vehicle storage area. Time and time again, through our value-engineering, we have found better, more cost-effective solutions, where the savings and increased value cover the cost of our fee.

Scope

Marcus Samuelsson, one of America’s most widely acclaimed chefs and winner of Top Chef Masters, brings his internationally praised signature cuisine to his Harlem Restaurant, Red Rooster. The restaurant and event hall have a floor area totaling over 9,000 sq. ft. and include a kitchen on each level. We worked with noted restaurant interior designers on this project and provided project management, architectural design, code consultation and structural engineering services.

Approach

By researching and thoroughly understanding every aspect of the project, we provided solutions that saved considerable amounts of space, time and money. The client pays for the restaurant per square foot, so we made sure to maximize its potential by carefully space planning for the most seating areas. Filings were meticulously orchestrated to avoid delays in the project. Because the building was existing, we reviewed old code and new building code options to determine which gave us the optimal front of house space.

Impact

Although deemed impossible by other consultants, we obtained an approval for the use of the existing building vault space of almost 2,500 sq. ft., creating enormous value for a restaurant in need of space. Our mark was seen in nearly all aspects of the project, including review of the site for development prior to lease, aiding in selecting the team of consultants and contractors, layout design, management of all filings (including the special permit for the event space), and structural design for extensive interior alterations. We gained over 200 sq. ft. of additional front of house space, and provided constant monitoring of the critical path to the grand opening.
