Plumbing design included re-routing natural gas piping in order to comply with the current New York City building code and assisting the architect with providing an appropriate rating for the same. The total cooling capacity replaced in the facility was approximately 100 tons. DM Engineers also worked with the facility during construction execution and the NYC DOB close-out process.
Columbia University engaged DM Engineers as an owner’s project engineer to oversee the replacement of the high-pressure boiler plant’s condensate polisher and softener while maintaining an operational 32-acre academic campus during construction.
Work involves planning and coordination to initially install new condensate softeners with all ancillary controls and electrical service. Subsequently, the chemical composition of the boiler water treatment is modified to allow for an equipment switchover without affecting the steam quality. Thereafter, the same process was utilized to change the three condensate polisher tanks. DM Engineers led the engineering and construction team during this project.
DM Engineers was retained by Columbia University to lead the implementation of the Pupin Physics Building natural gas system serving the teaching laboratories. Scope of work included leading the design and executing the construction project engineering. System included installing natural gas serving six floors of academic space while maintaining occupancy. Additionally, the project upgraded the facility’s gymnasium dyers natural gas service and mechanical ventilation.
Columbia University engaged DM Engineers as a project engineer to manage the replacement of the fuel oil controls system while maintaining an operational 32-acre academic campus during construction and with a fuel system totaling over 170,000 Gallons of oil.
Controls upgrade included the replacement of all the system control valves, new HDMI panels and PLC software configuration, utilizing ladder, function block. New graphics and sequence of operations was developed for the upgrade. DM Engineers led the construction team during the executions, design reviews, controls development meetings, field installations and system commissioning.
KIPP School is a charter school, serving grades 1 through 6. KIPP schools are tuition-free schools that operate independently of the city Department of Education. The project was executed as a complete fit-out of a 6-story building and approximately 34,240 GSF. Space features include cafeteria, exercise room, classrooms, computer rooms, specialized laboratory classrooms, and administrative areas.
DM Engineers performed the commissioning of all the Mechanical, Electrical and Plumbing (MEP) disciplines of the project. Equipment commissioned include building exhausts fans, electric fine tube radiators, condensate pumps, electric duct heaters, air Conditioning Units (VRF), dedicated outdoor air conditioning unit (DOA), Computer Room Air Conditioning Units, heat recovery boxes, lighting and lighting controls, electrical panels, domestic water system, sewage system and building autonomation.
DM Engineers was brought on-board prior to the construction phase and was able to work with the project team to execute the work within 6 months as planned. DM Engineers developed the commissioning plan, pre-functional and functional checklists. During the construction, our team established construction checklists and pre-functional and functional testing forms, verified equipment installation to conform design specifications, documented construction issues utilizing Facility Grid Software and witnessed hydrostatic tests and duct leakage tests. During the turn over phase, DM endured the training execution, and required project documentation was delivered as required by the project owner.
NYC Local Law 87 (LL87) mandates that buildings over 50,000 gross square feet undergo periodic energy audit and retro- commissioning measures, as part of the Greener, Greater Buildings Plan (GGBP). The intent of this law is to inform building owners of their energy consumption through energy audits, which are surveys and analyses of energy use, and retro-commissioning, the process of ensuring correct equipment installation and performance.
After the corrective measures are implemented, an Energy Effciency Report (EER) is filled with the Department of Buildings. Building systems audited and repaired include systems that use energy or impact energy consumption including: building envelope, HVAC systems, conveying systems, domestic hot water systems and electrical/lighting systems.
DM Engineers was retained by Columbia Univeristy to manage the Retrocommissioning Measures (RCM) and Energy conservation Mesures (ECM) program for compliance with New York City Local Law mandates. Our team managed the energy audits, RCM & ECM field implementation, field verification and Department of Buildings (DOB) compliance submission for the phase II and III (on-going) of this campus wide program. The phases of the program encompased 31 buildings in phase II and 10 buildings in phase III and the project team implemented over 2,000 retro-commision measures and energy conservation measures.
The major challege during this program execution is performing the audits and implementation in a campus that is used year round, nontheless, our team manged the work and client expectations.
Pupin Hall was built in 1925 and it currently provides space for the Physics Department. The building is categorized as landmark because of the research advances in nuclear science during the Manhattan Project aiding the develop the first nuclearized weapon.
DM Engineers was retained by Columbia University to lead the implementation of replacement of the Pupin Physics Building natural gas system serving the teaching laboratories. Scope of work included leading the design team, procuring the contractors and executing the construction thru Building Department and Utility provider sign-off. The project included installing natural gas serving six floors of academic laboratory space while maintaining occupancy. Additionally, the project upgraded the facility’s gymnasium dyers natural gas service and mechanical ventilation.
The Schapiro Center for Engineering and Physical Science Research (CEPSR) is a research facility located in the Columbia Morninside Campus. CEPSR was built in 1991 and utilized the latest HVAC technology for its time.
Floors 4, 6, 7, 8, 9 and 10 contain offices and engineering and physics laboratories. The 10th floor houses a Clean Room which is used by researchers from many disciplines. The building lower floors and cellar house the campus high pressure steam plant.
DM Engineers was retained by Columbia University to lead the implementation of upgrade of Air Handling Units 7, 8, 9, 10 & 11. Scope of work included the replacement of chilled water, glycol recovery loop, and steam pipe trims, coils, dampers/ actuators, DDC controls (from pneumatic), fan motors, installation of variable frequency drives and AHU casing repairs of the units on the penthouse machine room.
Total volumetric flow for this project surpassed 200,000 cubic feet per minute, which services the upper floors of the building and which completely balanced at the completion of the project. Construction executed was carefully phased to maintained the building in full operation.
