STATEMENT OF WORK

Dated: February 2, 2026

A. OVERVIEW

Bay Pines VHA uses steam to create hot water used for heating buildings and to make domestic hot water. The pipes that carry this steam leaves the boiler plant (Building

#100F) and go underground out to locations where the steam is used. If there are locations where this underground steam diverges and goes to two separate buildings this is done in a manhole

There is a steam manhole between buildings 1 and 111 on the Bay Pines VHA campus.

This manhole is the junction point for the steam as it leaves the energy plant and goes to

Buildings 1, 71/101, 2, 37, 23 and 22. The steam at this location splits and goes to

Buildings 1, 22 and 23 via one pipe and the remainder of the buildings via another pipe.

There is an active steam leak in this steam manhole. The only way to safely evaluate this leak (determine the extent of the leak and thus the material needed to fix the leak) is to shut the steam down to this manhole from the energy plant. Due to the extent of the leak, it is thought (by in house, steam subject matter experts) that the steam will not be able to be turned back on to this manhole once it has been shut down, until the repair is made.

This will leave no heat to the buildings listed above until the leak is fixed. It is anticipated this leak will takes several months of time to repair due to lead time for materials and the amount of work to be done.

The piping on the exterior of this manhole is a proprietary jacketed system. Some of this pipe needs to be replaced to fix this leak, that is known. This pipe has a long lead time of months. In order to reduce the downtime for this repair new sections of this pipe will be ordered to ensure all possible leak and repair situations are covered before shut downs happen and repairs begin.

B. OBJECTIVE

The objective of this work is twofold.

First is to install rental heating hot water boilers in B71 and 101 to provide heating hot water to these buildings for the duration of the repair. These are the only buildings fed by this steam leg that houses patients overnight. Even with preordering the exterior piping before shutting down the steam to this manhole, this repair will take weeks to complete.

These boilers will need to be powered from a diesel powered generator as there is not sufficient available electrical power in the buildings.

Second is to purchase, install and test/commission all required steam piping to repair this leak. This will include digging up the ground at least 6 foot away from this manhole to replace 2 sets of pipes that go into and come out of this manhole as well as replacing all piping and fittings inside the manhole.

C. SCOPE OF WORK (RENTAL)

NOTE: Before the rental systems are procured and put into operation, all new underground piping needs to be ordered from Rovanco. Planning for and obtaining of the items needed for the rental systems can be done to coincide with an anticipated delivery date of the pipe. Once these new pipes have been received on site is when rental systems can be installed and started up.

Communication of these events to VHA FMS staff is critical.

1. To keep heat and domestic hot water to the patient occupied buildings of the

CLC (71 and 101) vendor shall provide all required systems and piping connections to provide heating hot water and domestic hot water to these buildings.

2. Vendor will provide electric powered hot water boilers. These boilers will be located inside the mechanical rooms of B71 and B101. The work of installing rental boilers for these buildings has been done recently and at that time a

Lattner, S165 LW (16.5 HP) and a TB-209 (27.5 HP) boiler were used for this purpose.

a. It is responsibility of the vendor to verify the sizing of each of these boilers based on the heating hot water and domestic hot water heat exchanger sizes in the buildings as these temporary boilers will be used for both heating hot water and domestic hot water. The above can be used for reference.

b. Spool pieces of piping are available on site to be used to connect these boilers to the buildings heating hot water systems. Spool pieces are VA property and will be returned to the VA at the end of the rental period.

c. Final connection from the boiler to the spool piece needs to be done with high temperature rubber hose. Vendor will be responsible for fabricating and installing this hose for each boiler.

d. Vendor will be responsible for all required maintenance of these boilers for the duration of the rental.

e. In the event of a failure that is not repairable within 24 hours vendor will provide replacement boiler(s) within 36 hours.

3. Vendor shall provide a diesel generator(s) large enough to power these boilers.

a. Vendor is responsible for sizing of these generators to ensure they are the right size and power (Volts, amps, phase) for the boilers.

b. Vendor will be responsible for keeping these generator(s) fueled. This will include checking the oil level while the generator is off for refueling.

c. Vendor will be responsible for all other required maintenance of these generator(s) for the duration of the rental. Oil changes, coolant level inspections /changes and other preventive maintenance required by the manufacturer.

d. In the event of a failure that is not repairable vendor will provide a replacement generator within 24 hours.

4. Maintenance of the boilers and generators shall be planned to coincide with each other when possible to limit down time.

a. All maintenance (planned or emergency) shall be communicated to the

COR for this project.

5. Vendor will provide all electrical power cords needed to safety go between generator(s) and boilers.

a. This will include any cable protection needed for areas power cords will cross walkways.

6. Vendor shall provide fence to go around generator(s) for duration of the rental period. 6 foot tall minimum. Double locked with a VA lock to allow VA access.

7. Vendor will start up and verify full operation of this rental system. This start up can be done on a weekday.

a. All systems (generator and boiler) shall be tested for full operation before final connections are made to reduce downtime.

8. Once the rental systems to provide hot water (heating and domestic) are complete to B101 and B71 then the steam to the manhole can be shutdown and

LOTO.

9. Once the need for the rental system is complete, vendor will be responsible for disconnecting the boilers from the piping systems and restoring the piping systems to what they where reconnecting the heating hot water in the mechanical room for B71 and B101. This cannot be done until steam has been restored to B71and B101 mechanical rooms.

SCOPE OF WORK (LEAK REPAIR)

NOTE: All piping, fittings, valves, welding and other associated work done for this repair shall follow VHA TIL spec section 33 63 00, Steam Energy Distribution and 33 08 00

Commissioning of Site Utility Systems. There are other notes throughout this section that are above and beyond these specs. They need to be followed as well.

1. All HPS (high pressure steam) and PC (pumped condensate) pipes are being replaced. This applies for pipes internal and external to the manhole. (External to ~6 feet of the manholes or to the anchors, which ever is further)

2. If investigations are needed of the pipe outside the manhole that is allowed before the steam system is shut down.

a. No shutdown of the existing system to investigate the inside of the manhole is allowed.

b. Investigation holes are not required to be back filled, provided 6 foot tall chain link fence surrounds the investigation locations.

3. Vendor shall work with Rovanco piping company to obtain 4 pieces of jacketed pipe to be used to replace the pipe on the exterior of the manhole.

a. Pipe must match the pipe defined in Rovanco job no 41556.

Documents for this Job no. can be found in Appendix B of this SOW.

b. For the pipes that go to the West of the manhole (to Building 1) and to the North of the manhole (from B100) there is a concrete anchor (thrust block) within 5 feet of the manhole. Enough pipe will have to be ordered to allow this anchor to be replaced and these sections of pipe will need the anchor detail (from drawing set) to allow the anchor to be replaced.

i. If exploratory digs need to be made to determine the exact location of these anchors to then determine the amount of pipe to be ordered, that is allowed. Holes will not have to be refilled, just will need to be protected by fencing. (6’ chainlink)

c. All pipes that go to the south of the manhole (to B71) do not need to be replaced.

d. The underground High Pressure Condensate pipes (From b100 into

Manhole and from Manhole to B71) are not being replaced. They are being abandoned in place.

e. Rovanco will determine the amount of total pipe that needs to be ordered and the materials and procedures to be followed for installing these sections of pipe. Pipe will not be ordered from Rovanco without them creating a drawing set for this order with installation instructions.

f. These sections of pipe shall all have Rovanco manufactured above ground end seals on the ends going into the manhole.

i. Carrier pipe for each pipe section shall extend at least 3 foot past the end plate for connection of the piping inside the manhole.

g. This step (ordering the pipe) is critical to happen first. This pipe has a long lead time and no other work can happen on this project until this pipe has an anticipated delivery date or the pipe has been delivered to the site.

h. It is critical to follow all Rovanco handling and storage recommendations for this pipe. Damage to the pipe, rusting of the pipe, wet insulation will render these section of pipe unusable and they will have to be replaced at vendors cost.

i. This includes unloading of the pipe, when the pipe is being stored on site and while it is being installed.

4. Vendor shall provide a LOTO procedure for the steam to the manhole. This shall include all HPS, HPC, PC and electrical sources of energy into that manhole.

5. The exterior work around this manhole will need a dewatering system to ensure water is removed from the excavations. Vendor needs to plan for that.
