Verizon

104 Broad Street

New York, NY

Verizon’s downtown central office telecommunications equipment building at 104 Broad Street was hit hard by Superstorm Sandy in 2012, flooding several of the levels of the building. Verizon immediately called our team to manage the extensive MEP rebuilding process.

The first phase of the project was to stabilize the buildings. Our team assessed the existing conditions, specified how to remove damaged equipment and established temporary power and AC services for the critical telecommunication equipment.

In the second phase, we developed a Master Plan and budget. We then redesigned the utility electric service transformer vaults, making them flood proof. We designed four new 120/208 volt, 4000 ampere electric service switches, main distribution switchboards, two 2500 KW, 4160 volt diesel engine generators and a 1500-ton centrifugal chiller plant.

In the third phase, we designed a new sprinkler infrastructure system including a new fire pump, riser piping, and sprinklers. We also designed smoke control systems in all telecommunication equipment spaces.

CBRE

1411 Broadway

New York, NY

We have worked with CBRE on many projects in this 40-story building as the base building engineer. Our work ranges from design drawing reviews to workplace fit-outs, to ASHRAE Energy Audits to reviewing/updating engineering building standards and technical support.

One of the significant projects we completed was the upgrade of the existing MEP infrastructure in order to help meet the client’s goal of meeting the criteria to be classified as a Class A office building. Our first responsibility was to help develop a masterplan for the MEP infrastructure upgrade. We then completed a due diligence assessment of existing building electrical services, condenser water systems, chillers, base building air handling units and the BMS system.

American Express

200 Vesey Street

New York, NY

We have worked with the building manager at 200 Vesey on multiple infrastructure upgrade projects in our role as base building engineer, including replacing the BMS system and replacing the interior control systems.

The replacement of the Building Management System (BMS) has improved efficiency and reliability. Our first step on this project was to provide a comprehensive survey of the existing systems and make a recommendation for design, including review of vendors and systems types, a construction budget and project schedule. We came up with a strategy to install a new system, while keeping the existing system operational in order to minimize downtime to the building.

Our commissioning team has worked closely with the building management on the replacement of all of the interior control systems. Over a four month period, our team verified all hot water control valves, tested the actuators for all air dampers, and reviewed the control valves to ensure that they were functional as designed. We also worked with the controls vendor to verify the air flow out of the VAV and fan powered boxes. One of the added benefits that our commissioning team added during the control systems testing process was that we were able to also identify related heating and cooling issues and work with the building team to address these issues. This project was completed while the space was occupied, so all of our work had to be done through a process that would not affect the company operations.

Existing conditions scanning

Client

RXR Realty

530 Fifth Avenue

New York, NY

As part of the repositioning of this building, the owner decided to add retail space to the ground floor and a new elevator/escalator. Our existing conditions scanning team scanned the cellar and sub-cellar mechanical space, which consisted of a congested, base building mechanical plant. The team then used the information as the basis to coordinate new elevator and escalator pits into the existing mechanical space.

The benefits of scanning the space included being able to create detailed dimensioning of access between existing elements that were not readily accessible for typical measurement. We were also able to coordinate the elevator/escalator pits with the existing conditions, and generate sketches overlaying the proposed blocking for the pits on existing conditions scans to illustrate spacing and systems affected.

With respect to collaboration with RXR, our scans facilitated discussion and enabled remote collaboration with all project stakeholders. And, most important to the client, we were also able to minimize disruption to the existing systems during construction.

Cross Country Savings Bank

Middle Village, NY

Cross County Saving Bank is a local bank that was originally founded in Brooklyn, New York over 125 years ago. The newly constructed building includes two floors of office and retail space and a cellar level used for storage and mechanical support.

Our civil team was the first to kick-off our work at the site, preparing a site plan layout, grading and drainage plan, and designing the site utility connections. They worked with various city agencies to obtain approval for the development of the site; they prepared plans for permitting approvals by the DEP, the DOB and the Parks Department (for a Tree Planting Plan).

Our MEP and technology teams designed a power generator to prevent any downtime. We coordinated with ConEdison for new electric service to site and with National Grid for gas service to the site. Our technology team designed a new end-to-end structured cabling system design coordinated with new voice, data, and video distribution system requirements.

Our commissioning team is managing the commissioning process and working to ensure that the systems will operate as designed. Our commissioning scope includes the Air Handling Units (AHU), standby power generator and gas fired generators.

We performed an energy model for the space and by doing so achieved a 28% energy reduction from the baseline model.

Brookfield Properties

One NY Plaza

New York, NY

We have worked with Brookfield Properties for many years as the base building engineer at One New York Plaza. Projects have ranged from developing the base building and LEED standards, to replacing the chiller plant, from the design of common corridors and white-box spaces to the design of sprinkler loops, and to special inspections.

One of the most challenging projects was the replacement of a 6,000-ton chiller plant. The existing chiller failed because of a turbine explosion, and our solution was to design a 5,000-ton chilled water plant using electric water-cooled centrifugal chillers and well as two 2,000-ton and one 1,000-ton machines. We worked closely with different vendors to provide customized chillers because of space constraints. Our work included the design of a state-of-the-art Building Management System that allows the entire plant to be operated at maximum efficiency.

Another interesting project was the replacement of the building’s base building air handling units (AHU). Because the building is close to the Hudson River, many of the building systems have been affected by the corrosive sea air. Our commissioning team surveyed and tested the motorized dampers on the AHUs to determine which ones should be repaired or needed to be replaced along with the actuators. Out of a total of 500 dampers, we recommended approximately 40% be replaced with new. Changing the dampers solved the operational problems.

In addition to providing MEP design for common building areas and white box spaces, we have completed various sprinkler Special Inspections projects. We have witnessed the hydrostatic testing of the sprinkler pipework and conducted a field inspection to ensure that the installation of the sprinkler system complies with the NYC Building Department approved drawings.
