North Campus Underground Utilities Repairs

USDA, Ames, IA

1/6/25

BACKGROUND:

During a 2024 excavation around Valve Vault 105 to replace the chilled water lines for building 5, there were some issues with other utilities discovered in this area. There are portions of the campus steam condensate piping from buildings 5 and 7 to steam valve vault 105 that have deteriorated beyond the point of repair and need to be replaced. Both steam condensate lines from building 7 and building 5 are damaged and leak condensate into the ground. In addition, a 12-inch reinforced concrete storm sewer of this area has a sag in the pipe which causes improper drainage and seepage from one of the joints in the storm sewer piping. It was discovered that this 12-inch concrete storm drain is close to resting on the fiberglass PPW (Pumped Pretreated Waste) PPW piping and will need some support before backfilling. Finally, during a 2013 excavation, in this same area, the leak detection conduit that runs between PPW Vault 110 and PPW Vault 111 was damaged and was not repaired correctly which causes ground water to enter these vaults through the conduit.

SCOPE:

This project will consist of 5 separate sections of work as identified below:

1. Section 1 – Replacing a section of campus steam condensate piping from building 7 to steam valve vault 105.

2. Section 2 – Replacing a section of campus steam condensate piping from building 5 to steam valve vault 105.

3. Section 3 – Replacing sections of sagging storm drain piping.

4. Section 4 – Repairing the previously damaged 2-inch leak detection piping.

5. Section 5 – Repairing leak in west PPW piping.

Section 1: Replace condensate piping for building 7

1. Remove approximately 4,400 square feet of concrete roadway from Valve Vault 105 to center of concrete parking area on the west side of building 5 as shown on page P03 of the drawings. Approximately 1,600 square feet of roadway was removed during a previous excavation and is currently backfilled with sand and gravel. This area will also need to be re-excavated.

2. Expose the condensate line from Valve Vault 105 to center of concrete parking area on the west side of building 5 as shown on the drawings. The damage is believed to be approximately linear 125 feet from the vault, but it’s location will need to be verified by the contractor. The contractor shall excavate to the nearest joint beyond this location and replace the pipe in whole sections of pipe.

3. Remove the existing 4-inch steam condensate pipe up to the 6-inch condensate line inside Valve Vault 105.

4. Install new 4-inch insulated campus condensate piping from the 6-inch line inside Valve Vault 105 to the end of excavated area. This shall include replacing the existing expansion joint in Valve Vault 105 (details on drawing P07). This shall also include replacing the existing steel sleeves and mechanical link seals where the new piping enters and leaves the concrete vault. Upon completion, configuration shall match existing.

5. Contractor shall review the specifications for options for steam condensate piping. If a factory-prefabricated, pre-insulated water piping rated for steam condensate ratings is chosen, the preferred manufacturer is Perma-Pipe or approved equivalent.

6. Perform leak tests on the new 4-inch condensate pipe to ensure it is leak free as per the specifications.

Section 2: Replace condensate piping for building 5

1. Expose the building 5 condensate line from Valve Vault 105 to steam manhole east as shown on drawing P03. This area is a combination of grass and concrete.

2. Remove the existing 3-inch condensate pipe from the nearest valve inside the east manhole up to the 6-inch condensate line in Valve Vault 105. This includes the expansion loop.

3. Install new 3-inch condensate pipe from Valve Vault 105 from the 6-inch condensate into east manhole to the valve (see drawing P11). This is to include the sparge pipe and expansion loop in the line. This shall also include replacing the steel sleeves and mechanical link seals where the new piping enters and leaves the concrete vault and manhole. Upon completion, configuration shall match existing.

4. Contractor shall review the specifications for options for steam condensate piping. If a factory-prefabricated, pre-insulated water piping rated for steam condensate ratings is chosen, the preferred manufacturer is Perma-Pipe or approved equivalent.

5. Perform leak tests on the new 3-inch condensate pipe to ensure it is leak free as per the specifications.

Section 3: Replace sections of storm drain

1. Expose the existing 12-inch storm drain to the north of Valve Vault 105 (see drawings P12).

2. Extra care and caution shall be taken around the 2 fiberglass PPW (Pumped Pretreated Waste) piping that is under the existing storm drain.

3. Expose sufficient area to remove 18 linear feet of the 12-inch storm drain.

4. Install new foundation base for new storm drain piping per ASTM C76. Use extreme caution when compacting over the top of the fiberglass PPW lines. Ensure there are no sharp objects that could damage the PPW lines during compaction of base materials.

5. Install steel reinforcement bracing over PPW lines between 2 sections of base foundation as shown on drawing page P04. Neither the new storm drain, nor the new support system shall be in contact with the fiberglass PPW lines. The support system shall prevent any physical contact with the PPW lines. Contractor shall design and engineer the needed support and provide to Contracting Officer’s Representative (COR) as a submittal.

6. Install 18 linear feet of Class IV RCP (Reinforced Concrete Pipe) storm drain piping per

ASTM C76.

7. Properly slope the new 12-inch storm drain piping per industry standards and codes.

Slope shall be from east to west and be towards the storm drain located close to Valve Vault 105. Match slope of remaining pipes to ensure water drains appropriately to manhole. See elevations on drawing page P02.

8. Ensure the joints on the storm drain are sealed with no cracking or leaking per ASTM C443.

Section 4: Replacing damaged leak detection conduit

1. Expose the PPW lines within the area of previously excavated area (see P03, P12, and P13) to expose the Robroy PVC coated conduit that runs along the west side of the PPW lines.

2. Coordinate the disconnection of the leak detection system and pit float system with the USDA staff from PPW111 to PPW110. The contractor shall then remove of all wiring between PPW111 and the junction box in PPW110 from the damaged conduit.

3. Existing stainless steel float systems and electrical components of leak detection systems shall be reused.

4. Remove bent and damaged section of Robroy PVC coated conduit between closest couplings in the excavated area.

5. Replace damaged section of leak detection conduit with materials of the same make and manufacturer, Robroy Plasti-Bond or approved equivalent.

6. Replace all wiring removed from the conduit with new. Do not reuse the existing wiring.

7. Install new wiring back into PPW Vault 110 through PPW Vault 111 via the conduit system. See page P16 of drawing set for details on wire size and type.

8. Contractor shall use waterproof connectors and splices when reconnecting wiring.

9. Seal open ends of 2-inch leak detection conduits once wiring has been installed and tested to prevent ground water from entering the vault through the conduit system.

Product recommendation: Polywater® FST™ Foam Duct Sealant.

10. Coordinate with USDA staff for the reconnection and testing of the leak detection system and pit float system and to ensure that both systems operate as designed.

Section 5: Patching and repairing leak in west PPW line.

1. Expose the two fiberglass PPW lines to allow for pressure testing and leak locating.

2. Contractor shall expose the PPW piping from the 12-inch storm drain up to the existing chilled water lines for building 5 (approximately 10 feet), all the way around the piping to allow for easier locating of the leak. See image on page P12 of drawings for reference.

This area is under the previously exposed areas seen in drawing P03. This area will coincide with the excavation needed for Section 4.

3. Once exposed, the USDA facilities staff shall pressure test the interstitial piping of the west PPW line to locate the leak via an air test. The leak is believed to be at one of the two couplings on the secondary containment shown on drawing P12 on the west line.

4. Once leak has been located, contractor shall repair the area with an approved epoxy fiberglass repair kit.

5. USDA facilities staff shall then retest to ensure integrity of the interstitial pipe. The pipe must not exhibit leaks from this area of repair and must maintain a pressure of 10 PSI of air for at least 1 hour.

General contractor requirements across all sections.

1. Contractor shall hydro-excavate all areas to locate and expose existing utilities. Once all utilities in the specified areas are located and exposed, contractor shall be allowed to use normal excavating processes. No existing infrastructure shall be damaged during the hydro-excavation and excavation processes.

2. Contractor shall ensure that all excavated areas are appropriately shored or sloped to prevent trench collapse per OSHA requirements. Spoil offset may also be required to prevent any soil collapse that could move or otherwise damage the exposed utility infrastructure.

3. The scope of the project shall be performed in a neat, workmanlike manner and shall be sequenced for efficient workflow and to minimize interruption to the daily activities and ongoing research at the facility to the greatest extent possible. This includes coordinating excavation and activities across sections to minimize the project duration.

4. All existing to remain utility infrastructure should be protected from the elements as appropriate. In particular, the piping shall be appropriately secured to prevented from experiencing movement in the event of water entering the excavated areas, particularly during heavy rainstorms. Regular dewatering of this area may be necessary due to the water table. All means and methods of completing this are the responsibility of the contractor and shall not damage existing infrastructure.

5. In the event of two or more consecutive days/nights freezing temperatures, or a deep freeze, the excavated areas shall be backfilled to prevent damage to critical infrastructure. An exception may be made only at the CO and COR’s discretion.

6. All areas shall be backfilled and compacted per the specifications. Areas should not remain exposed to the elements longer than is needed to complete and inspect the repairs. Backfilling around the PPW lines requires special consideration as defined in the specifications.

7. Contractor shall coordinate any utility outages with the COR at least 2 weeks in advance of beginning work.

8. Work may not be completed in the vault unless steam has been shut off and locked out.

Steam through this vault is critical to nearby buildings. As such, any work in the vault must be completed between Friday after 5:00 PM when steam can be shutoff and Saturday at 5:00 PM when steam must be brought back online. It is probable that the vault will need to cool prior to people entering it. If vault work cannot be completed by 5:00 PM Saturday, work must halt. Multiple outages may be scheduled at one time but must be coordinated with campus. Depending on the time of year and current projects, consecutive weekends may or may not be acceptable. If repairs are not completed during the set of scheduled outages, campus will require no less than two weeks notification for the next planned outage(s).

9. It is strongly recommended that the contractor prefabricates all piping infrastructure to be placed inside the vault prior to scheduling the outages to limit the total duration of steam outages.

10. All equipment necessary to moderate conditions inside the vault are the responsibility of the contractor.

11. All construction debris from this project shall be removed from the site by the contractor at the end of the project.

12. Contractor shall be responsible for backfilling the trench and repairing/restoring any disturbed portions of the surrounding area back to its original condition.
