Statement of Work

Building 154, Air Compressor Replacement

USDA, Ames, IA

7/22/22

Project Requirements:

Background:

Building 154, the Central Utility Plant, currently has (2) two 100HP, TS-20 Sullair Air Compressors each with a rating of 575 CFM at 115PSI. Both air compressors were installed in 1999 and need to be replaced and upgraded with new units. These air compressors supply compressed air to various systems on campus and are critical to plant operations as well as maintenance and research. Both air compressors are no longer able to maintain required air pressure on campus and have become harder to maintain over the last few years thus resulting in unreliability issues as well as inefficiencies. Both existing air compressors utilize two (2) Sullair desiccant air dryers to maintain the -40 degrees F dew point needed in the compressed air system. Currently, both Sullair dryers operate constantly due to the fact that if one of the dryers is placed offline, moisture will accumulate in this “offline” dryer. For energy savings, efficiency, and the need to have N+1 redundancy, the new desiccant dryers shall be able to run on just one set of air dryers while still providing the 575 CFM compressed air at 115 psi pressure at -40 degrees F. The buildings supplied by these air compressors are Buildings 3, 4, 5, 7, 9, 20, 21, 22 and 24.

Scope:

Contractor shall be responsible for:

1. Verifying any and all dimensions and shall carefully examine the air compressor room and surrounding space and shall make all necessary investigations to become thoroughly aware of the existing conditions and all difficulties involved in the completion of the work in accordance with the contract documents prior to the submission of your bid and commencement of work.

2. Maintaining air pressure in Buildings 3, 4, 5, 7, 9, 20, 21, 22 and 24 throughout the project by use of two (2) temporary electrically powered air compressors supplied and maintained by the Contractor.

a. Liquid gasoline or diesel, or natural gas or propane air compressors will not be allowed.

b. The temporary electrically powered air compressors shall be rated at 125psi at approximately 600CFM each.

c. The temporary electrically powered air compressors shall be connected to the existing air dryers to maintain the appropriate dew point setting of -40 degrees F.

d. USDA requires two (2) electrical air compressors to maintain the N+1 requirement to continue air pressure on campus in case of a failure of one of them.

e. Contractor will need to schedule air outages at least two (2) weeks in advance due to the unpredictability of ongoing scientific projects and Select Agent requirements.

f. Contractors may keep one of the existing Sullair air compressors online and in operation in lieu of a 2nd temporary air compressor, if possible.

g. The Contractor-furnished, temporary air compressors shall be located on the north side of Building 154. There is a 2-inch copper line compressed air connection located on the outside of the building. These temporary air compressors can be connected here and piped in a configuration that will allow switching between the temporary air compressors if needed during normal plant operations.

h. There is an existing 200A disconnect on the north side of Building 154 that the contractor can utilize for one of the temporary air compressor electrical connections.

i. Contractor will need to install a 2nd electrical service for the other temporary electrical air compressor or use one of the existing air compressor’s service.

3. Training the Utility Plant staff on how to properly operate the Contractor-furnished, temporary air compressors in case of any issues that may come up since the facility is operated 24 hours a day, 7 days a week. Utility Plant staff will need to know how to start and stop these units and respond to any faults that may occur after hours.

Contractor shall provide the Utility Plant personnel a contact name and number to call if any issues come up with the temporary units after hours.

4. Removing the two (2) existing 100HP Sullair air compressors and disposing of them in accordance with federal, state, and local codes. This is to include all fluids contained within each air compressor.

5. Replacing both Cutler-Hammer 200A, 600V disconnect switches feeding each existing air compressor. Both switches failed a recent short circuit study performed in 2022. Both existing disconnect switches shall be replaced with new disconnect switches that are properly rated above the calculated kA rating according to the latest study. Short circuit study results shall be provided to the contractor for reference.

6. Installing (4) four new automated valves. Two (2) on each discharge of the existing Sullair air dryers and two (2) on the discharge of the new air compressors and connecting them to Metasys for monitoring and automation.

a. Johnson Controls will need to be involved in the setup and programming.

b. Contractor shall ensure new automated valves are compatible with Metasys.

c. Contractor shall install new automated valves on the discharge side of each air dryer to gain the ability to isolate each dryer to eliminate the need to run both sets of dryers at all times. Currently, both sets of air dryers run constantly to prevent the offline set from accumulating moisture. This is a loss of 90CFM just to keep the offline set dry. Contractor shall install valves to isolate the discharge on the offline set and keep the inlet open and then we should be able to prevent moisture from accumulating in the offline set. This will gain us 90CFM.

7. Installing two (2) new water-cooled, rotary screw air compressors. Detailed specifications are listed below. New air compressors must have:
