Project Overview: 
1900 Arch Street is a 14 story, 3-tiered mixed-use building in downtown Philadelphia, comprising 330,000 square feet of floor area and 248 residential units. Designed and constructed using a pre-engineered, pre-fabricated light gage wall and floor panel system, 1900 Arch street is the tallest pre-fabricated load bearing metal panel structure built to date; with an impressive 13 stories of load bearing wall panels.
McLaren's Role: 
McLaren was called upon well after the Design Development phase to perform significant structural redesign, without adversely impacting architecture, to bring the project in line with budget and time constraints. Highlights of the structural redesign include a secant pile shored excavation and foundation wall system, the steel transfer level below the pre-fabricated load bearing wall panels, an 8 inch deep Comslab floor deck permitting 26 foot clear slab spans, preparation of shop drawings for pre-fabricated light gage load bearing wall panels for the interior of the structure, and an extensive green roof encompassing 2/3 of the roof area. By using a pre-engineered, pre-fabricated light gage wall and floor panel system; McLaren was able to facilitate a shorter construction period and gain permits for an earlier start time for all interior trades.
