Steam must be maintained at all times during the contract to meet the facility needs, except for short-term shutdowns (usually less than 8-hour duration) scheduled in advance with the VAMC. Contractor shall completely prepare site for building operations, including demolition and removal of existing structures, and furnish labor and materials and perform work for The Replace Steam & Condensate System (Oval 1) project as required by drawings and specifications. Visits to the site by Bidders may be made only by appointment with the Contracting Officers Representative (COR). Offices of Miller-Remick, LLC, as Architect-Engineers, will render certain technical services during construction. Such services shall be considered as advisory to the Government and shall not be construed as expressing or implying a contractual act of the Government without affirmations by Contracting Officer or his duly authorized representative. Before placement and installation of work subject to tests by testing laboratory retained by Department of Veterans Affairs, the Contractor shall notify the COR in sufficient time to enable testing laboratory personnel to be present at the site in time for proper taking and testing of specimens and field inspection. Such prior notice shall be not less than three workdays unless otherwise designated by the COR. All employees of general contractor and subcontractors shall comply with VA security management program and obtain permission of the VA police, be identified by project and employer, and restricted from unauthorized access. Temporary Utilities: As described in the Specifications, limited use of electricity for 115V tools will be available with no charge to the contractor for performance of the contract. The contractor must provide its own sources for larger loads, such as welding equipment. Domestic water will be available at no charge to the contractor, but the contractor is responsible for all temporary connections. The contractor must provide reduced pressure backflow preventers for all locations of connection to the CVAMC system and must maintain the temporary connections to prevent leakage. Adequate space for staging of materials will be in coordination with the VAMC in accordance with the Specifications. ITEM 1, The Replace Steam and Condensate System (Oval 1) project is for the partial removal and replacement of the underground medium pressure steam and condensate piping to and from the buildings located in Oval 1 (buildings 1, 2, 3, 4, 5, 6, 7, 8, and 9) and some of the outlying facility buildings (building 10, 11, 12, 15, 16, 17, and 69). This project includes but is not limited to the following: Be advised that post design of this project, the VA awarded the Tree Management and Sidewalks System project (VA project 542-14-104) for construction. This project will have an impact on the accuracy of the contract documents. The area known to be most impacted is the underground pipe path between Building No. 7 and Building No. 8 where a rain garden is planned. The contractor shall include in their bid the restoration of the rain garden (coordinate with COR). The facility steam system operates year-round for HVAC (i.e. building heating and AC reheat) and domestic water heating. It is the intent of this project that all work will be accomplished and completed during the warmer months (approximately April 1 through November 1). Shut down of the steam system must be minimized. The contractor shall plan and coordinate all required steam shut-downs with the VA COR. Steam shut-downs are limited to 8-hours maximum. The Contractor shall develop a phasing plan using new steam valves and providing new temporary steam and condensate piping, valves, pipe supports, and if necessary, providing temporary building and domestic water heating to achieve this objective. All temporary piping shall be insulated and jacketed and routed in a manner to avoid blockage of walkways and building access. In the event the temporary piping is routed across a sidewalk or roadway, temporary pedestrian and vehicle ramps shall be added. The contractor s phasing plan is subject to final approval by the VA. Final approved phasing plan shall not be grounds for a change order. Due to the age of the original steam and condensate system, asbestos containing materials (ACM s) are suspected. In order to minimize disturbance, the existing piping, and trenches etc. shall be abandoned in place with the exception of the piping and trench sections interfering with the installation of the new system. The VA has removed a majority of the ACM s over the years, however there are sections and areas of the original system that remain and have not been abated. The known areas of concern are within this project: Existing manhole No. 3 (EMH3), and associated piping to and from Building No. 11. Sections of the original underground steam & condensate piping system and concrete pipe trenches. The new pipe pit within the basement of Building No. 16. Note: The existing grade is capped with a flowable fill or concrete mixture. The unexcavated basement sections located in Building 10. Prior to demolition, the contractor shall have the materials, soils, etc. Tested for the presence of ACM s and if tested positive properly removed. Contractor shall provide unit pricing for the testing and possible removal of ACM s as follows: ACM assessment at the abovementioned locations. Cubic foot of soil (EMH3 and Building No.16). Cubic yard of concrete (existing underground pipe trench and concrete soil capping (Building No.16)). Linear foot of pipe insulation for pipe sizes 3 to 8 (EMH3 & underground piping). Linear foot of underground piping for pipe sizes 3 to 8 . Cubic yard of shotcrete encapsulation for the Building 10 basement to cover the existing grade and cap the soil.

Asbestos encapsulation of Building 10 basement with Shotcrete The contractor shall provide all equipment, labor, materials, tools, and supervision required to perform asbestos abatement by encapsulation of the dirt in the sections of crawl space where the steam line runs. This involves removal of all debris from the surface of the crawl space and removal of dirt to the extent required to facilitate the work of the contract. All removals will be considered to have some level of asbestos content. Additionally, all surfaces of existing pipes, insulation and walls/columns will be washed prior to encapsulation. Since the washed surfaces include broken edges of fiberglass insulation on the chilled water pipes, the wet insulation will be removed, and the insulation edges will be squared off and sealed. The encapsulation includes placement of a plastic barrier across the surface of the crawl space dirt, and application of a 6-inch thick shotcrete layer. Vertical plastic barriers will be applied to separate the remediated portions of the crawl spaces from the un-remediated portions. Pervious concrete squares will be installed 40 50 feet apart in the shotcrete to facilitate drainage from any leaking pipes and prevent moisture build-up associated with mold and legionella. The scope of this requested change is to lay out a membrane and blow shotcrete over the dirt floor of the basement spaces. The covered area must extend the entire width of each portion of basement, from wall to wall. The scope also includes all necessary containment and PPE and safety requirements associated with the work. The scope also includes any soil excavation needed prior to shotcrete application. All containment, abatement and encapsulation work must be performed by a qualified and certified abatement company, and must include proper disposal of all asbestos-containing and contaminated materials. Excavation must be accomplished at both drip legs to accommodate proper installation of the new drip legs as detailed as well as all necessary maintenance access. The excavation depths must account for the necessary thickness of water-permeable shotcrete or pervious concrete cover. The area of the excavation must be a minimum of 6 square feet to prevent pooling of water below the drip legs. Any leaks in the crawl space must be able to drain through the shotcrete/concrete cover. The approximate areas of basement space needing shotcrete covering as described above are as follows: Building 10: 4400 sf (broken up in two side by 2600 sf and 1800 sf) Building 10 basement BID ITEM II: Delete the new steam and condensate piping from Building No. 14 to Building Nos. 15 and 12.
