GHT provided mechanical, electrical, and plumbing engineering design services for the 26,000 SF Madison Marquette project. The tenant fit out is located in the newly constructed 1000 Maine Avenue SW. GHT was also the Base Building engineer at 1000 Maine SW; a project that included Dedicated Outdoor Air System (DOAS). Madison Marquette is a mix of open work stations and enclosed private offices, a LAN room with 24/7 supplemental HVAC, conference rooms, a cafe, and other office support spaces. Madison Marquette required the relocation of existing DOAS terminal units away from sound-sensitive areas, as well as the addition of new DOAS terminal units. GHT also specified thermostat locations for each terminal unit, provided CO2 sensors are tied into building automation system (BAS) and provide demand-controlled ventilation control.
