645-DOTRFQ-2925-2027 Amendment 2.pdf

This is Amendment 2 to a Request for Quotation issued by the Iowa Department of Transportation's Architectural Services/Resources & Acquisition Bureau for baseboard heater replacement in offices at Atlantic Maintenance Garage in Atlantic, Iowa. The project, identified as D4 - Atlantic MG Baseboard Heater Replacement (Project Number BG-1A31(012)-80-15), involves revisions to the original scope of work. The amendment modifies the heating system specifications by increasing the baseboard heater size on the south wall of the breakroom while eliminating one heater on the west wall. The bid date for this amendment is August 7, 2026. Additionally, the amendment introduces Alternate 1, which allows contractors to propose the furnishing and installation of wall-mounted hydronic heaters with line voltage thermostats as an alternative to traditional baseboard heaters, provided the equipment is compatible with the current boiler system and maintains equivalent BTU output to the existing installation.

The alternate specification requires thermostats to be configured to activate the fan when room temperature reaches 55 degrees while otherwise providing radiant heat. Contractors submitting proposals for Alternate 1 must coordinate clearances prior to installation to ensure proper fit and operation. The amendment is subject to the Iowa Department of Transportation's standard Purchasing Terms and Conditions for the bid process. No pricing information, incumbent contractor details, set-asides, or funding sources are specified in this amendment document.
