Description

The State of Iowa’s Department of Administrative Services is seeking a qualified design‑services firm to prepare complete design documents for a partial roof replacement (approximately 12,260 sq ft) at the Hoover State Office Building in Des Moines. The scope includes removal of the existing ballasted roof system, installation of a fully‑adhered EPDM roof, removal of abandoned rooftop equipment, and resetting roof drains, plus associated architectural, structural, mechanical, and electrical design work. The project follows a tight schedule: proposals are due 14 Oct 2026, design contract execution begins late Oct 2026, with final construction‑document delivery by 15 Jan 2027, followed by construction phases through June 2027. The solicitation requires separate technical and cost proposals, a 120‑day price guarantee, $2 M professional liability insurance, and compliance with Iowa’s modified ConsensusDoc 803. • Design services covering architectural, structural, MEP, and specialty roof‑system engineering for a 12,260 sq ft roof. • Mandatory deliverables: 50 % and 95 % construction‑document sets, cost opinions, and full construction‑administration support. • Evaluation based on firm qualifications (30 pts), staff experience (15 pts), state project experience (10 pts), approach/methods (35 pts), and project execution plan (10 pts).

Budget estimate

$280,000 – $350,000

Addendum 2 lists a total project budget of $348,390, which includes design, construction‑document preparation, and related services. Assuming design services represent roughly 80‑90 % of that total (typical for design‑only contracts), the expected award amount for the design portion is estimated between $280 k and $350 k. Factors influencing the range include the firm’s staffing plan, hourly rates, reimbursable expenses, and the 120‑day price‑guarantee clause.
