Cardozo Education Campus HVAC Upgrades

The District of Columbia (the “District”) Department of General Services (“DGS” or the “Department”), on behalf of the District of Columbia Public Schools (“DCPS”) is seeking a design-builder (the “Design-Builder” or “Contractor”) to perform this scope of work at the Cardozo Education Campus HVAC Upgrades (“the Project”).

This Project addresses system aging, operational deficiencies, and deferred maintenance through a targeted program of capital renewal and system optimization. The work includes replacement and upgrades of select HVAC equipment, repairs to existing systems, enhancements to the building automation system (“BAS”) and controls, comprehensive preventive maintenance measures, and retro-commissioning to restore and verify system performance.

The Project design-to-budget is **$3, 500,000** for construction hard costs.

Project Goals

• Complete a comprehensive equipment survey.
• Restore design functionality to all equipment and controls.
• Repair or replace defective equipment.
• Upgrade the building controls systems.
• Retro-commission (RCx) to the HVAC and BAS to verify conformance to design parameters.

Performance Criteria

The scope of the Project generally includes, but is not limited to, the following. The Contractor shall:

• Survey each piece of equipment to evaluate condition and estimate life cycle position.
• Identify assets using refrigerants subject to the American Innovation and Manufacturing (“AIM”) Act phasedown.
• Identify all upgrades necessary to bring equipment to Day-1 design conditions.
• Complete upgrades and replacements approved by DGS. This includes AHUs, RTUs, cooling towers, water-source heat pumps, central plant HVAC equipment, etc.
• Replace the existing Siemens BAS/Desigo CC building management system with a non-proprietary system. Replace controllers and control devices.
• Upgrade the existing Delta enteliWEB system to the latest version. Update the graphics and build out the central plant. Install power and water submeters and integrate them into the trending platform.
• Replace the controllers at each AAON AHU, RTU, and ERV with open-source, programmable, BACnet controllers.
• Install a second plate and frame heat exchanger in the central plant to facilitate future maintenance and resiliency.
• Complete an ASHRAE Level 3 Energy Audit.
• RCx to the HVAC and BAS following ASHRAE Standard 202—Commissioning Process for Buildings and Systems. RCx shall be completed by a qualified Commissioning Provider (CxP).
• Improve safe access to rooftop-mounted equipment by replacing existing vertical ladders with aluminum stairs or 60° ship ladders with platforms conforming to OSHA 1910.25 Stairways.
• Include permit expediting services as part of the Preconstruction Fee or Design Fee.

The Contractor’s scope of work will be divided into two Phases: (i) the Design and Preconstruction Phase; and (ii) the Construction Phase.

**Site visit:** The Contractor shall be required to visit the site, become familiar with local conditions under which the work is to be performed, and correlate personal observations with requirements of the performance criteria and scope of work.

The Contractor shall include with the proposal a recovery plan to address potential non-conforming products or services, such as damaged materials or errors in measurement.

The Design-Build Fee shall be allocated with fifteen percent (15%) of the Design-Build Fee to the Preconstruction Phase (“Preconstruction Fee”), and eighty-five percent (85%) to the Construction Phase.
