The Dallas County Board of Supervisors reviewed a 100% design-development (DD) budget estimate for renovations to the County Attorney offices at 902 Court Street. County materials in the meeting packet show Turner Construction’s final 100% DD estimate at $3,708,262, after accepted value‑engineering items that the submission says produced a $682,156 reduction from earlier budgets.
The design documents submitted on June 30 describe a main-floor plan including a practice courtroom, new HVAC with individual room controls, tubular skylights, and proposed furniture. The project team’s schedule in the packet expects construction to begin in early January 2027 and to take about nine months, with substantial completion targeted for late September 2027.
Turner’s deliverable lists a MasterFormat cost breakdown across divisions (HVAC, finishes, electrical, contingencies), construction manager services and fees, and owner allowances. The packet also lists alternates and accepted cost reductions such as using CPVC for sprinkler branches, over‑floor raceways instead of floor boxes, minimizing line‑voltage lighting controls, and selecting more economical carpet tile. One add alternate—adding room‑scheduling devices for conference rooms—is priced at $31,263.
The Turner cover letter included in the packet states, “We are pleased to submit our 100% Design Development Budget Estimate for anticipated project costs for the Dallas County – County Attorney Renovations … in the amount of $3,708,262.00,” attributed to Jamie A. Rochleau of Turner Construction. The submission also identifies exclusions and requests for further coordination (RFIs) on items such as roof tie‑in details, panelboard clearances, and generator relocation.
The packet contains a detailed RFI log and a responsibility matrix showing Turner and the design firm (Farnsworth Group) assignments and exclusions. It also includes a CPM schedule that traces design, bidder pre‑approval, GMP formation, and a two‑phase construction sequence with milestone dates and detailed task durations.
Next steps recorded in the packet include continuing coordination on outstanding RFIs, finalizing bid documents later in 2026, and proceeding to the procurement and GMP phases consistent with the CMAR delivery plan. The Board did not record a formal vote on awarding construction work during this meeting; the materials were entered into the record for review and subsequent action.
Funding details and whether the County will bring a construction contract or GMP to the Board for approval were not decided at the meeting and were listed as items for future consideration.
