The Department of General Services ("Department" or "DGS") is issuing this Request for Proposals to engage a design-builder for the construction of a new elementary school building on the campus of Orr Elementary School located at 2200 Minnesota Avenue, SE, Washington, DC 20020. DGS envisions the construction of a new building consisting of approximately 70,000 square feet (the "Project"). The Project will also include the demolition of the existing structure and the construction of landscaping, surface parking and playgrounds on the balance of the site. Construction activities will be conducted in two phases, with the construction of the new building occurring first between the winter of 201 7 and summer of 2018. The new building will be sited to the north and east of the existing building. Once the new building has been constructed, the existing building will be demolished and replaced by surface parking, landscaping and related site work. It is contemplated that this phase of work will occur between the summer of 2018 and the spring of 2019.
