Mark III’s scope for this 643K SF tilt-up warehouse project included all MEP trades. The building consists of a large warehouse space for processing packages as well as staff offices, trucking lounges and restrooms. Despite the pandemic, holidays, and temperamental weather, the project site transformed from a dirt patch to tenant mobilization in only five months. Being on a compacted schedule, the project team worked to complete all overhead shell space quickly to allow the customer to begin equipment layout prior to construction completion. The ability to work in tandem on final steps will further expedite the overall schedule, allowing Amazon to open a fully operational distribution facility within their project deadline. Additionally, both the plumbing and electrical teams leveraged technology and prefabrication to further expedite the schedule. The virtual construction department coordinated and laid out the MEP systems using Trimble before sending cut sheets to the manufacturing facility for production.

The plumbing scope included a prefabricated natural gas main, domestic water main, and water closet carriers. Our field team installed over (382) plumbing fixtures and 26,000 feet of piping (stainless, copper, PVC, and carbon steel).

The mechanical scope included the installation of (54) rooftop units and (15) 24′ diameter high-velocity, low-speed (HVLS) fans. The rooftop units were installed via helicopter pick in under three minutes per unit. Leveraging Mark III’s manufacturing facility to prefabricate sections of ductwork instead of building everything in the field allowed the field team to keep up with the aggressive 5-month schedule.

The electrical scope included the installation of onsite communications, generators, UPS, backup power system, (2) 4,000 amp services, testing & analysis, primary/secondary infrastructure, Title 24 lighting and lighting controls (over 2,300 lighting fixtures), motor controls, VFD’s and solar. The Mark III manufacturing team prefabricated all wall-mounted transformer supports, dock-leveler disconnects, charger racks, lighting whips, and strut racks. In an impressive feat, the electrical team was able to run 60K linear feet of underground in just 3 weeks.
