PURCHASE DESCRIPTION

COLD ROOMS REPAIR

1.0 REQUIREMENT

General The Vendor shall provide and install three (3) small and one (1) medium sized glycol Air Handler Unit (AHU), four

(4) pumps, four (each) three-way modulating mixing valves, ball valves and isolation valves, twelve (12) temperature probes, and four (4) Programmable Logic Controllers (PLCs) in three (3) small and one (1) medium sized Cold Room in the Main Lab Cold Rooms Complex. These units will be installed in place of the existing valves, controllers, Air Handlers and associated circulating equipment. Replacement piping runs to connect into the system and insulation must also be supplied and installed to the specifications required. These units will replace existing obsolete AHUs on a one-for-one basis that date from the 1960s and have extremely unreliable and troublesome operation. Because the scrapping and removal of the original units will expose cracks and other imperfections in the walls of the Cold Rooms, it is also necessary for the Vendor to re-seal the rooms as part of the installation work to return them to their current functional condition.

An option to provide two (2) medium sized glycol Air Handler Units, two pumps, two (2) three-way modulating mixing valves, ball valves and isolation valves, three (3) temperature probes, and one (1) PLC for installation in the Cold Pit, a fifth room in the Cold Rooms Complex, shall also be quoted as a part of this supply-with-installation requirement.

Key Evaluation and Performance Metrics (Table 1): Table 1 entitled “Key Evaluation and Performance Metrics” provides the key specifications that must be satisfied, and how they will be used as part of the proposal review process. The specifications are separated into Threshold (minimum mandatory specifications) and Objective (desired specifications). To be considered, your proposal must meet all of the Threshold specifications. Proposal ranking will increase as vendors demonstrate their systems also meet many or all of the objective specifications. We understand that some systems may not be able to meet all of the Objective specifications, but nonetheless we encourage vendors to submit proposals showing where they can meet specifications.

2.0 REQUIRED EQUIPMENT SPECIFICATIONS

2.1 Cold Room 153

Cold Room 153 is 27 feet wide by 25.17 feet long by 12 feet high with 10-inch-thick Styrofoam insulation. The condition for infiltration in the insulation of the room shall be assessed as “poor” when performing calculations based on these dimensions.

The Medium-Sized Low Temperature Air Handler Unit, General Specifications. The CR.153 AHU must operate off 480V 3ph 60hz AC, utilizing hot glycol defrost, and have a rated capacity of approximately 3.5 TR (Tons Refrigeration) at a room temperature of -30F using -37F glycol (the assumed specification of heat transfer must be for 60% ethylene glycol), a lower than standard 7-degree temperature delta between the process fluid and the target room temperature. Electrically heated drain pans and defrost lines must be standard off a separate 110- 120V circuit with adjustable temperature control. The unit must be capable of working to supply variable room temperatures in a range from 70F to -30F.

3.0 INSTALLATION & DELIVERY REQUIREMENTS

Site Survey: Before ordering any parts, the vendor must conduct a site survey and gather detailed site data to validate the final election, sizing, and placement of components.

Delivery timetable: Equipment under the base bid must ship NLT 31 December 2022 to be delivered to CRREL in time to meet the time-critical cooling requirement these systems represent. If exercised, the equipment under Option One must ship within 60 days of the base bid equipment (1 March 2023).

Spill Prevention: Bolt on flanges must be installed on the cut glycol pipes during demolition to provide supplemental holding of the severed glycol lines during the period of work in case the isolation valves experience leakage or blow past. The remainder of the glycol system for Cold Rooms not part of the scope of this work will remain in regular operation during the installation of the new equipment.

General Installation: The quoted cost will include full installation and start-up as well as warranty against defect.

Installation must be accepted by the government following submittal of as-installed drawings and results from system pressure testing. Government acceptance depends on testing the system to temperatures of -15F room temperature, held for a period of 48 hrs., for each cold room on which work is performed. Testing shall be conducted separately for each Cold Room.

Installation, Per Room, Base Bid: The quoted cost shall include installation of all supplied AHUs, pumps, circulating loops, valves, PLCs and associated systems to include piping runs up to 15 ft in length per each glycol loop (cold/hot) per AHU with insulation (not to include length of circulating loop with insulation, which is dependent on vendor AHU selection). This is a total of 30 ft of piping and 30 ft of insulation per room, as well as electrical conduit and wire feed, terminating power in existing electrical panels, and daily clean up to contractor supplied dumpster.

Installation, Per Loop, Cold Pit Option One: The quoted cost shall include installation of all supplied AHUs, pumps, circulating loops, valves, PLCs and associated systems to include piping runs up to 20 ft in length per each glycol loop (cold/hot) per AHU with insulation (not to include length of circulating loop with insulation, which is dependent on vendor AHU selection). This is a total of 40 ft of piping and 40 ft of insulation per loop, and 80 ft of piping and 80 ft of insulation in total in the Option, as well as electrical conduit and wire feed, terminating power in existing electrical panels, and daily clean up to contractor supplied dumpster.

Demolition of old systems, Base Bid: The quoted cost will include removal, and demolition of pipe connections, old control valves, old pneumatics and controls, old AHU and all associated systems as field-marked by the Government. The quoted cost will include removal and demolition of all existing electrical circuits associated with the existing AHUs, and power and controls to the existing pneumatic system. The vendor will need to remove the light fixtures to successfully demolish the old AHUs; a new installation must then be supplied.

Demolition of old systems, Cold Pit Option One: The quoted cost will include removal, and demolition of pipe connections, old control valves, old pneumatics and controls, old AHU and all associated systems as field-marked by the Government. The quoted cost will include removal and demolition of all existing electrical circuits associated with the existing AHUs, and power and controls to the existing pneumatic system. The vendor will need to remove the light fixtures to successfully demolish the old AHUs; a new installation must then be supplied.

Rating of Piping and Insulation: New piping and insulation must be rated for -50F temperatures to support the use of process glycol at temperatures as low as -40F. All piping must be compatible metals to the existing piping to be removed and must be complete through the wall of the room. All components of the system handling cold process glycol must be insulated to a standard equivalent to the Dow/Polyguard ZeroPerm insulation system, or its equivalent from another manufacturer.

Repair of Damage from Demolition and Installation: Based on previous experience by the Government in the installation of evaporators and relocation of evaporators in the Cold Rooms Complex, and the condition of the rooms, which were built of vintage Structural Insulated Panels dating to the 1960s, damage to the airtight seal of the rooms, including buckling and delamination of the Marlite paneling on the walls, is expected during the demolition of the old AHUs and installation of the new AHUs. The following special measures must be taken to restore the rooms to as-new condition when installation is completed:

a. Wash, acid etch, and caulk all seams of all existing Marlite paneling areas in each cold room in which an AHU is installed. Caulking must be moisture impermeable and rated to -30F or better.

b. Apply one coat of primer to all existing Marlite paneling areas.

c. Apply two finish coats of acrylic paint rated to -30 degrees Fahrenheit to all existing Marlite paneling areas.

d. Replace lighting fixtures removed during demolition.

The vendor is not expected to guarantee or warranty an airtight seal. The Government accepts all liability from the repair work described above and its success at restoring a proper seal to the Cold Room on which the installation work for the AHUs has been performed.

Training: One (1) day of training for up to eight (8) personnel must be provided in the operation of the new system, and one (1) day of training for up to eight (8) personnel on the basic maintenance procedures.

Testing: Before payment for installation, certified leak and pressure tests must be conducted on all pipe systems. All testing and cut ins need to be scheduled in advance with the TPOC.

Equipment Warranty: The vendor is requested to provide information explaining their equipment warranty and support policies to cover system problems or malfunctions inherent to the system (i.e., not caused by customer use).

Equipment that fails to perform as required will need field service deployments by Vendor technicians for check-out or trouble shooting; the government requires the vendor will address equipment malfunctions inherent to the system (i.e., not caused by CRREL use). A standard one-year warranty applies.

Point of Contact (POC) Requirement: Contractor shall identify a single point of contact with decision-making authority. His/her duties shall include, but are not limited to, ensuring contractor compliance with security, safety, scheduling, and non-smoking requirements. See Sections: 7 Safety, 8 Scheduling, 9 Security, and 10 Smoking Policy. The POC is required to be present at an initial post award conference after award of this contract. See Section 8.0, 2. Post Award Conference.

Technical Point of Contact: TPOCs offer technical backgrounds as subject matter experts (SMEs) in areas relevant to the contract. TPOCs provide value added technical feedback to the vendor and contractor performance feedback to the Contracting Office (KO). TPOCs may coordinate with the contractor to consult, support execution, assist with access to necessary government facilities or supplies, review reports, review deliverables, and act as the government sponsor where engagement with other government entities is required (e.g., site access, product transition). The TPOC shall allocate necessary time and attention to this contract to fulfill all product review and acceptance responsibilities in a reasonable timeframe as determined. Recurring failures to execute TPOC responsibilities shall require the KO to inform the TPOC’s First and/or Second Level Supervisors.
