SECTION 1 – GENERAL PROJECT DESCRIPTION

The project will execute the repair or replacement of the Underground Utilities of Steam, Domestic Water, Sanitary and Storm Sewer at the White River Junction Vermont VAMC. The Hospital and all buildings with few exceptions must remain operational 24/7 throughout the project.

SECTION 2 - BACKGROUND

The original buildings of the WRJ VAMC campus and utility systems serving them were constructed circa 1930’s and 1940’s. Throughout the years, building have been renovated, expanded and added to the campus. A large portion of these utilities are original or have been patched as a result of failures. This project concerns the Domestic Water, Steam, Sanitary and Storm Water utilities. Failure of any of these services poses risk of operational interruption.

· The WRJ VAMC relies on a dependable source of potable water to maintain clean and sanitary operating conditions and for fire protection. Portions of the supply lines were replaced in 1998 with ductile iron pipe, but most lengths are cast iron pipe over 80 years old. All sections have experienced failures and multiple patches. The WRJ VAMC relies on a dependable source of water to maintain clean and sanitary operating conditions and for fire protection.

· The existing boiler plant serving the campus, located in Building B-2, distributes medium pressure steam to the buildings on campus. The direct buried section of steam carrier piping from building B-28 to Buildings B-4, B-6, and B-7 was installed circa 1937, and is original to the buildings it serves. The existing steam carrier piping, the MPS & PC lines and the carrier pipe house have survived far past the typical manufactured life expectancy and are showing signs of leakage and insulation degradation.

· All wastewater is conveyed offsite to the municipal collection and treatment system maintained by the Hartford Vermont Department of Public Works Wastewater Division. The sanitary sewer system is a critical utility for the operation of the WRJ VAMC. The facility depends on continuous operation of the sewer system to remove wastewater from the facility and maintain clean sanitary operation. Blockage or collapse of the sewer lines would result in sewer backups within the Medical Center’s buildings and would cause disruption to the VAMC’s operations and could create unsanitary conditions in the facility; Vitrified clay pipe is known to have extensive root intrusion and cracking in many areas. Asbestos cement pipe also shows signs of deterioration and have been patched in many areas.

· The stormwater sewer system is an important utility for the operation of the WRJ VAMC. Blockage or collapse of the stormwater lines would result in unsafe conditions on the roadways and pedestrian routes within the campus, either through the formation of sinkholes around collapsed pipe, or from flooding induced by stormwater collection segments which are not functioning properly. Failing stormwater systems are also an environmental concern and could lead to erosion and sedimentation issues on the campus and adjacent properties. The stormwater system collects runoff from across the campus. Corrugated metal pipes have deteriorated, and vitrified clay pipes were found to have tree root intrusion, cracks and fractures. Asbestos cement pipes and reinforced concrete pipes also show signs of deterioration, multiple patches and offset joints. Some manholes and catch basins have critical deficiencies.

K. Utilities:

1. White River Junction VAMC uses about 47,000 gallons of potable water per day. Potable water is supplied by Hartford Vermont Department of Public Works through an 8” water main at Route 5 near the main entrance, routes to Building 2 where it is pumped to the water tower. From the tower the water delivered throughout the campus by a distribution network. Because replacing water supply lines could risk service interruption or repair of structures/sidewalks/roadways or other utilities, a new location is proposed. Refer to drawings and specifications to accurately determine lengths water pipe and quantities of various valves and hydrants that will be replaced. Refer to Specification Section 01 00 00 for instruction to operate, exercise, fully inspect, and if necessary repair all station valves and hydrants.

2. The Boiler plant delivers medium pressure steam to many buildings on campus via direct buried insulated pipe known to contain asbestos. Condensate is collected and pumped back to the Boiler Plant. Refer to drawings to accurately determine lengths of Steam carrier piping will be replaced. New sleeves are to be provided at the inlet and outlet of each building, including patching and sealing. All steam connections to existing building steam piping are to be made inside the buildings. Existing interior building steam piping systems are to remain and are not included.

3. The WRJ VAMC’s wastewater collection needs are fulfilled by a sanitary collection system that was originally constructed in the 1938 to 1942 period, then appended as the facility expanded over time. All wastewater is conveyed offsite to the municipal collection and treatment system maintained by the Hartford Vermont Department of Public Works Wastewater Division.
