Baseboard Heater Replacement in Offices at Atlantic Maintenance Garage

The Iowa DOT is seeking competitive quotes to replace and repair existing baseboard (radiant) heaters in the office spaces of the Atlantic Maintenance Garage. Bidders must provide a full replacement of designated heaters per the attached design plans, coordinate clearances, and ensure proper disposal of removed units. Work will be performed under DOT supervision, with a required 24‑hour notice prior to any installation, and must be completed by the contract’s estimated completion date. An optional alternate allows substitution with wall‑mounted hydronic heaters, subject to boiler compatibility. • Replace specified baseboard heaters “in kind” with Weil‑McLain Model 75 WL‑3 units (or equivalent). • Provide proper disposal of abandoned heaters and coordinate required clearances (12″ front, 6″ sides, 12″ above). • Deliver the completed work by October 15, 2026, with a start date of August 31, 2026; all work confined to Monday‑Thursday, 7:30 am‑3:30 pm business hours. • Optional Alternate 1: wall‑mounted hydronic heaters with line‑voltage thermostats, matching BTU output of removed units. • Contractor must furnish a performance & payment bond (if contract ≥ $25,000) and maintain required insurance; on‑site training for DOT staff is also required.
