1.0 BACKGROUND ON THE GOVERNMENT’S REQUIREMENT:

The Cosumnes River Preserve (CRP) is a multi-operator facility managed by the Bureau of Land Management (BLM). The primary onsite administrative facility is the Visitor Center. The HVAC system for the Visitor Center was damaged during flooding of the nearby Cosumnes River in 2023. The current aging and damaged HVAC system places many critical HVAC components below the Visitor Center finished floor elevation which is associated with the water level of recurrent runoff events.

This requirement is to replace the current HVAC system with one that has its critical system components largely above an established flood elevation. A replacement system has been designed and will be implemented with execution of this requirement.

2.0 GENERAL SCOPE OF WORK:

The contractor shall remove the existing HVAC system and its components from the Visitor Center. The contractor shall then install the new system according to the associated project drawings and specifications.

Location of Work:

Project Site Locations:

CRP Visitor Center (38.26572°, -121.43934°)

• Accessible via Franklin Blvd from I-5 Exits 493 - Thornton.

Period of Work Performance:

The period of work performance for this requirement is estimated to be from the time of award through August 31, 2024. The installation of the HVAC system performance should take up to two weeks to avoid an inconvenience to CRP and the vendor.

The work including the pre-work conference meeting, site visits and planning meetings, mobilization, construction, and de-mobilization must be completed within the Period of Performance.

3.0 OVERALL OBJECTIVE(S):

The objectives are to:

• Remove and dispose of existing HVAC system and associated system components.

• Install new system according to project drawings and specifications.

4.0 REQUIREMENTS:

General Requirements

1. Work will be conducted in both an open office and a public space, and the contractor’s access and work schedule shall be coordinated with the Contracting Officers Representative (COR) and the CRP Manager after award. Where disturbances are expected to be minimal, work may proceed during CRP business hours. The Visitor Center may be closed during typical business hours in order to accommodate work more expeditiously with prior approval from

COR.

2. See attached for general requirements are listed in the Project Specifications, Sections 01 01 15 through 01 79 00.

3. Specific requirements for successful execution are listed in the Project Specifications according to the associated function.

Warranty Materials and equipment furnished under this requirement shall be covered by the most favorable commercial warranties given to customers for such materials or equipment. The rights or remedies provided herein are in addition to and do not limit rights afforded to the Government by other clauses. With respect to warranties, expressed or implied, from manufacturers or suppliers for materials or equipment furnished under the requirement the Contractor shall:

1. Obtain warranties that would be given in normal commercial practices.

2. Require warranties to be executed, in writing, for the benefit of the Government.

3. Submit warranties to the Contracting Officer prior to the final inspection.

5.0 TASKS:

The contractor is to conduct all work as detailed in the Project Drawings (Attachment 2) and Specifications (Attachment 3). Specific tasks for the project include, but are not limited to:

1. In addition to where appropriate and called for in the Project Specifications, provide COR with submittals as detailed below:

• Proposed construction schedule

• Health and Safety Plan

• List of equipment to be installed

• Narrative of proposed concrete source

2. Conduct on-site preconstruction conference involving staff from BLM and those associated with Cosumnes River Preserve.

3. Remove and properly dispose of the entirety of the four split systems.

• Includes but not limited to furnaces and condensing units, their associated refrigerant piping, supply and return ductwork, air devices, natural gas piping, condensate piping, controls, and supporting fixtures/concrete pads.

4. Remove and properly dispose of supporting fixtures and concrete pads associated with existing HVAC equipment.

5. Patch and repair abandoned openings in walls, floors and ceilings where equipment and air devices reside.

• Where patch and repair of openings “to match existing” is not practical, such as in carpeted floors, alternative solutions will be discussed with BLM.

• Existing openings shall be reused as much as practical for new system to minimize repair work.

6. Install structural concrete pads for HVAC equipment. According to:

• Project Drawings, Structural Plan.

• Specifications, Sections 03 20 00 & 03 30 00.

7. Install new HVAC system, equipment and associated components, according to Project Drawings and Specifications.

• Including but not limited to; Heat Pumps, Fan Coils, supply and return ductwork, controls, thermostats, supporting fixtures, electrical, refrigerant and condensate lines.

• Fan coil locations shall be installed in a manner that minimizes impact to the building’s architecture and informative displays, as well as allow routing of refrigerant and condensate lines down through walls to the crawlspace.

• New heat pumps shall be mounted on elevated stands that will be installed on a new concrete housekeeping pad. Heat pumps will reside a minimum of 30” above the ground, which is roughly equivalent to the bottom elevation of the building’s floor joists.

• New mechanical systems will all be tied to a new, central control panel mounted in the southeast mechanical room. This system will ultimately be tied to the BLM’s central controls, NOC, for both local and remote control of the system.

• The existing electrical infrastructure at the Visitor Center shall be reworked to support new mechanical systems. Where practical, new underfloor refrigerant line supports will be sized to also accommodate new electrical conduits. Likewise, new conduits serving any particular fan coil will be routed through the same floor openings and wall cavities as the refrigerant lines. This approach shall be consistent throughout the project to minimize floor penetrations.

8. Contractor shall provide COR with operation and maintenance manuals. COR and CRP Manager shall also be briefed on basic operational controls prior to final acceptance.
