3.1.26 Machine Installation, Startup and Testing.

3.1.26.1 Work to be Performed by the Arsenal. This project is classified as a turn-key with the contractor being responsible all work associated with the installation unless otherwise stated. Upon receipt of the required installation and foundation drawings (see 3.1.17), Watervliet Arsenal will designate an installation site and outline a general machine location on the shop floor. Once the machine is installed, positioned and rough leveled by the contractor or their designated rigging crew Watervliet personnel will run utilities (power and air) to first points of connection on the machine. Watervliet must be provided with sufficient time to accomplish these connections. However, if the installation instructions supplied by the contractor are incomplete or insufficiently detailed, installation work will stop and the contractor will be required to dispatch a service engineer. Installation will resume upon his arrival and continue under his guidance.

Note: If installation instructions, foundation drawings and electrical and hydraulic schematics are not delivered at or before the times specified (see 3.1.17), the Government reserves the right to forestall delivery and/or final acceptance testing of the machine by an amount of time equal to the delay in receipt of instructions, drawings or schematics.

3.1.26.2 Work to be Performed by the Contractor. This project is classified as a turn-key with the contractor being responsible for all costs and work associated with the installation unless otherwise stated. The Contractor shall be solely responsible for all costs associated with skidding and shipment, rigging, and installation at WVA. Once an installation site is identified by Watervliet personnel and if required, a foundation is constructed, the contractor or their designated third party shall layout and core drill the holes for the machine anchor bolts. Please note that the majority of the Watervliet Arsenal’s shop floor is covered with 2” thick wood block. It shall be the contractor’s responsibility to cut out and remove wood block and to supply and install any leveling pads necessary for installation. Contractor personnel shall arrange for rigging services to off load the machine and contractor personnel shall be on-site at Watervliet when the machine arrives and is off loaded to supervise the placement of the machine on the installation site by the rigging service. Outside rigging services should be advised that only certified grade 8 chains are permitted to be used at the Arsenal and that all rigging slings must be tagged and certified for the weights being lifted. In most cases no Arsenal forklift services and/or Arsenal personnel will be available for the installation. Only propane powered forklifts are permitted and must also be equipped with a roll cage. Operators of forklifts shall have and be able to produce valid forklift licenses. Arsenal overhead pendant cranes (within load capacities) can be used by the contractor/rigging service for the installation. The contractor shall provide written certification to the WVA representative that all contractor/rigger personnel are qualified, through either formal training or experience per OSHA, to operate pendant controlled overhead cranes. Contractor personnel shall also adhere to the WVA requirements to wear OSHA approved non-tinted safety glasses with side shields and safety shoes while in the manufacturing shop areas. The contractor shall ensure they bring all equipment/material necessary for the installation of the machine(s). Watervliet does not have the resources to provide such material. Crane capacity within each building is limited (2, 5, 10 or 15 tons) and therefore if not adequate then the contractor will need to provide alternate means necessary for the installation. Specific building crane capacities where the equipment is to be installed should be verified with the WVA technical POC.

Once the machine is positioned and rough leveled by the contractor WVA personnel will run utilities to the machine. Watervliet must be provided with sufficient time to accomplish these connections. The contractor, through his own service personnel shall be fully responsible for the startup and testing of the machine, conduct any acceptance tests specified in sections 3 & 4 and perform the required on-site training. The contractor and the service personnel shall remain until the machine activation and testing have been successfully completed. Under no circumstances should the contractor plan on gratuitous Arsenal assistance for diagnosis, troubleshooting or repair of the equipment during activation and testing. Should such activity prove necessary, it shall be the contractor's responsibility to provide the appropriate labor and materials. If the contractor chooses to request Arsenal assistance in lieu of providing his own resources, the request will be reviewed by the Technical POC who shall reserve the right to impose a charge for the assistance. Approvals, even on a charge basis, should not be taken for granted since there is no guarantee that appropriate Arsenal personnel will be readily available. In such cases, the Arsenal will not be held responsible for delays in acceptance of the equipment resulting from nonavailability of Arsenal personnel or Arsenalfurnished equipment.

IMPORTANT: Under normal circumstances the contractor will be allowed to work as long as is desired during normal work days. Contractor work outside Watervliet’s normal work days cannot be guaranteed. Watervliet is on a condensed work schedule. Normal work hours/days for this schedule are four 9-hour workdays (Friday off) one week and four 9-hour days, one 8-hour day (Friday) the following week. Contractor work on the Friday off and weekends cannot be guaranteed. Contractor’s classified as foreign nationals may further restrict work hours and days available.

If the contractor requests Watervliet Arsenal to ship misc. material via UPS, FedEx or by other similar carrier then the contractor shall provide their carrier account number for this purpose.
