The National Eye Institute (NEI) planned a renovation to Room 10N104 and 10N104A to accommodate a rearrangement of the existing equipment, installation of new equipment in order to create a new shared Tissue Culture Lab. The finishes in these two (2) rooms and Room 10N102 were also upgraded. The three (3) rooms were in the “A” Wing of Building 10. Room 10N102 was approximately 130SF and Rooms 10N104 and 10N104A were approximately 386SF. These rooms were adjacent to occupied NEI laboratories, so all work was confined to these three (3) rooms. The project was delivered using a Design-Build Methodology. The renovation of the 10th Floor “B” Wing included a Tissue Culture suite for the National Eye Institute, as well as mechanical and utility work to support these renovations. The project included requirements for environment of care impact, design and preconstruction documentation, utilities, noise and vibration, infection control, safety, fire safety including placing firestopping material on all holes and penetrations affected by the work, and closeout including wiping, heap-vacuum areas of work upon completion. Architectural scope of work included hazardous material abatement, removing existing metal panel partition, removing door/frame/hardware, base and wall mounted casework, shelving, gas cylinder restraints, resilient tile flooring, sink base cabinet, millwork, countertop, metal studs and drywall, metal panel partition, fire extinguisher, and windows. New work included installing metal strapping in all new partitions, gas cylinder restraints, new access panel, new countertop, 1 layer of 5/8” gypsum board on face of partition, metal stud framing, wall insulation, gypsum wall board (5/8” Type X), fire rated caulking, backer rod and sealant, general ceiling paint, acoustic ceiling panel, wall paint (Levels 1-5), integral 4” rubber cove base, and seamless sheet rubber in the tissue culture labs, and ante room. Installation of the partitions included requirements for framing to the underside of the deck, through the ceiling, underside of the ceiling, and fills existing wall opening. Matos installed new hollow metal doors and frames, door hardware, and new windows (4’11” x 4’6”). Electrical scope of work included removing the electrical raceway, and lighting. New work included installation of new card readers, access control panel, devices and power supply for door hardware. New LED lighting included connecting the new exit sign, various lumens, installation of new occupancy sensor, and emergency lightning panel. The project included requirements to provide wall penetrations for new conduit, 1” EMT conduit with pull strings to closest security panel, back box for card reader, connection to fire alarm devices, data drop wiring, emergency lighting, new 400A circuit breaker, data cabling and final termination, 2-1/4” EMT to IT room, and new panelboard with a surge protection device. Matos had to coordinate installation of new receptacles with the gas manifold installation. Mechanical scope of work included removing fan coil unit and associated utilities. New work included a floor sink. Project included work with lab services for argon, ambient water for injection, acetylene, compressed air, CO2, clean steam, cold water for injection, domestic water, deionized water, hydrogen, helium, high pressure plant steam, instrument air, lab water (hot and cold), liquid nitrogen, various pressures for steam, nitrogen, nitrous oxide, natural gas, oxygen, process air, process chilled water supply, propane gas, tempered water supply, purified water, reverse osmosis water, specialty gas, ultra-high purity nitrogen, vacuum, and zero air. Demolition scope of work included removing the existing hydronic supply/return piping, and induction air ductwork to/from existing header and cap at header piping/duct mains. Matos disconnected and demolished condensate piping from induction and fan coil units back to the riser, demolished the existing fan coil hydronic piping, exhaust air duct (454 CFM exhaust was demolished), FCU and wall mounted thermostat, and induction units and thermostats. New work including the installation of hydronic piping to the new fan coil units from the existing hydronic cooling and heating systems, connection of condensate line to primary and secondary drain pan for the fan coil unit, new fall coil units, wall mounted thermostats/humidistats and control valves. The balance volume dampers included 60 CFM, 165 CFM, and 80 CFM. Matos installed a O2 gas monitor, ¾” ball valves for HHWS/R lines, updated the BAS system and associated valves and thermostats, tied into new ¾” HHWS/R to the existing 2” building supply and return risers with wet tap connection. Matos connected the 1” CHWS/R to the existing 2” building chilled water line, rebalanced the supply and exhaust from constant volume ducts serving the wings, installed new DDC thermostats, connected condensate drain to existing condensate drain riser. Matos provided firestopping for all new/existing penetrations, provided duct transition from existing supply air duct to new 6” makeup air duct, provided full commissioning per 2015 IECC section C408. Installed duct mounted temperature transmitter. The FCU’s installed included 410 CFM, 170 CFM, and 520 CFM. Matos installed supply grilles, exhaust, ceiling return and laminar flow supply. Laboratory Equipment scope of work included the installation of bio-safety cabinet class II type A2, cell counter, refrigerated centrifuge, dry heat bath, CO2 incubator-double stacked, microscope, refrigerator/freezer, 4oC refrigerator-undercounter, mobile table, mobile cart, and flammable storage cabinet. Plumbing scope of work included removing waste, vent, lab water and lab hot water lines back to the risers. Matos demolished all lab gasses back to the risers within the utility chases. The existing lab sinks were demolished including associated lines. The existing safety shower was demolished included the associated plumbing. New work included the installation of new lab sink, new lab hot water and cold-water lines, waste, and vent lines to the new sink, connected new VAC lines from mains to the new biosafety cabinets. Matos installed new CO2 drop to each incubator, (6) new CO2 canisters connected to new auto changeover gas manifold system, (2) new O2 canisters connected to new auto changeover gas manifold system, routed vent piping up the utility shaft and vented through the roof. Matos provided lab hot and cold-water connections to thermostatic mixing valved located below the sink. Matos routed new 2” waste and 1-1/2” vent lines from the sink to existing riser connections in chase. Fire Protection scope of work included requirements to protect existing fire alarm and fire suppression scope of work including connecting to existing fire alarm control panel. The project included providing a new hydraulically calculated sprinkler system for a light and ordinary group 1 hazard. Matos replaced all sprinkler heads with new.
