This design-build project included infrastructure upgrades for new equipment located on the first floor. The project area contained a lab space and adjacent mechanical chase.
Mechanical scope of work included designing the necessary HVAC to support the installation of the VarioEdit System, the Trion Technology SIRIUS T2 System, as well as associated auxiliary equipment for both systems including VarioEdit System, VarioEdit Laser chiller, VarioEdit Computer (Monitor & PC), VarioEdit Dry Vacuum Pump (Purge), VarioEdit Dry Vacuum Pump (Exhaust), VarioEdit Plasma Asher, VarioEdit Plasma Asher Wet Vacuum Pump, VarioEdit Plasma Asher Computer (Laptop), VarioEdit Parylene Coater (wet pump internal), VarioEdit Cold finger for Coater, Trion SIRUS T2 System, Trion Chiller, Trion Leybold Process Pump, and the Room Refrigerator. Matos performed heating and cooling load calculations, including designing internal loads which included people counts, lighting, and required equipment loads from specifications or data sheets. Matos also provided air balance calculations and designed the system to ensure supply, return, and exhaust airflows were balanced and met all system requirements. The project also included requirements for a damper on the branch of the new exhaust duct, modifications to the EMCS system, sensors and alarms, and removal of existing chilled water lines both supply and return back to 30’ and capped.
Structural scope of work included the design, fabrication, and installation of new support frame (welded construction) for VarioEdit machine. Matos evaluated the floor structure with respect to room layout for potential floor vibration and ensured that floor vibration limits, as specified by the manufacturer, were not exceeded. Matos provided structural support, as required, for the balance of equipment to be installed as part of the SOW. This included provisions for three (3) pumps to be installed in the mechanical chase. Matos specified the design and performed required modifications to the raised access floor system to allow for installation of the equipment as part of the SOW, including cutouts, repairs, and any architectural modifications. Matos performed structural analysis and design for the existing structure being affected by the VarioEdit and associated component installation activities. This included researching and surveying the existing structure to determine existing conditions and original design codes. The existing structure was evaluated for any structural modifications or new loads placed on it, including any dynamic effects. All new structural elements and components were incorporate dead, live, seismic, wind, blast, and other loading conditions, as required. The analysis and design were being complete according to DOD UFCs, FC 1-200-01-MPO General Building Requirements, FC 3-301-01-MPO Structural Engineering, IEBC, and IBC.
Electrical scope of work included designing all necessary electrical equipment and connection to support the installation of the VarioEdit System, the Trion Technology SIRUS T2 System, as well as all associated auxiliary equipment for both systems. Matos surveyed 208/120V, 400A panels containing existing 30A, 3P, feed to the construction area. Matos removed the feed and all existing hardware in its entirety (approx. 30′). Matos surveyed 208/120V, 200A, and the panel containing four (4) 3P, spare breakers. Panel was approximately 120′ from construction area and 15′ from Trion. Matos verified the electrical design by measuring the load on a continuous basis with calibrated equipment or by data provided by the SCADA system. The load measurement study was for a minimum of two weeks and included Volts; Amps; KVA; KW; KVAR; PF; VTHD; CTHD. The data received was used in conjunction with a “look back” on historical data for higher loading conditions dependent on seasonal or operating conditions. Matos provided a metering service which was required to work in and around energized equipment. This included opening electrical equipment and connecting meters for the specified duration. Matos determined the extent of the metering required and was responsible for providing a Job Hazard Analysis and an Energized Electrical Work Notification to the Government for review prior to commencing work. Matos followed the Energized Electrical Work Notification Procedure for each circuit to be metered. Matos calculated the incident energy level and PPE requirement using this data either in ETAP, by hand calculation or by using any other method that clearly determined the PPE requirement. Matos completed an electrical surveying including tracing each panel’s sources back to the secondary unit substation and documenting rating/electrical characteristics of all devices.
