1. AG/RES.2911GSB SALE AND BIDDING PROCESS OAS Department of General Services Feb, 2018

2. RISK REDUCTION Technical Aspects Economic Aspects Legal Aspects • GSB market analysis. Identification of GSB expected selling price. • Identification of ADM remodeling/ retrofitting costs • Identification of expected costs for new building construction. • Construction and maintenance cost for underground parking lot. • Best Value proposal analysis for ADM remodeling and new building construction. • Identification of possible guaranteed construction costs for new building construction and ADM remodeling, as inputs for the RFP. • Preliminary review and overall approval of building construction plans. • Identification of design requirements and specific technical criteria by relevant federal and district agencies (NCPC, DC-HPO, NPS, CFA, and others). • Specific guidelines to be included in design proposal, as inputs for preparation of RFP. • Workspace analysis (# offices, cubicles, meeting rooms, etc.) • Determination of workspaces to be created and consolidated as part of the ADM retrofitting. • Updating ADM deferred maintenance requirements. • Workspace and parking space size requirement for the new building. • Soil analysis to determine feasibility and specific technical requirements for construction of underground parking lot. • Elaboration of design proposal for new building and blueprints for ADM remodeling. • Determination of specific technical requirements (architectural, mechanical, engineering) to be included in the RFP.

3. Bidding Process SCOPE OF WORK GSB FEASIBILITY STUDY • Market study to establish market value range and expected sale price of GSB building. • Technical analysis and identification of design requirements (NOB/ADM) • Estimated costs for construction of new office building and ADM retrofitting. • Preliminary agency review and approval • Concept feasibility report, summarizing results of individual studies and analysis of overall project proposal. Identification of risk and mitigation actions.
