O’Connor worked with the architecture firm Westlake Reed Leskosky (WRL) to provide cost estimating and scheduling services for the $20 million major historic renovation of the Renwick Gallery. Built in 1861, the Renwick Gallery is one of the oldest and most iconic buildings in the Washington, DC area. It is also on the National Register of Historic Places.

Plans for renovating the 34,000-square-foot masonry structure included a nearly complete replacement of the mechanical, electrical, plumbing, and lighting systems. Due to the age of the structure, significant structural modifications and strengthening was required.

O’Connor’s services included estimates and schedules at pre-design/basis of design, schematic, design development, and the 65%, 95%, and 100% construction document phases. We also assisted the client with pricing and identifying multiple alternatives of varying scope.

Throughout an iterative, seven-step process, O’Connor conducted market studies and outreach to the construction industry and subcontractors for feasibility and pricing. We factored in unique project considerations, such as its location (adjacent to The White House), moratorium planning (area closures), as well as extensive planning requirements.

As a result of O’Connor’s efforts, the project was bid less than a 1 percent variance from O’Connor’s estimate, and the CPM construction schedule was adopted and confirmed.
