Site work for a civil project in Walla Walla, Washington. Completed plans call for site work for a water / sewer project.

The US Army corps of Engineers, Walla Walla District is planning to award a Hybrid Construction with Supply project entitled Lower Snake River Navigation Lock Tainter Valve System Upgrades. The work is located at the Ice Harbor Project (HLD) in Burbank Washington; Lower Monumental Project (LMA) in Kahlotus, Washington; Little Goose Project (LGA) in Starbuck, Washington; and Lower Granite Project (LLA) in Pomeroy, Washington. The North American Industry Classification System (NAICS) code for this project is 237990-Other Heavy and Civil Engineering Construction with $45,00,000 in annual receipts. The scope of work includes replacing four culvert valve bodies with new valves (four at each site, sixteen total) at HLD, LMA, LGA and LLA. This will be a firm-fixed-price hybrid construction with supply contract. The construction portion has an estimated magnitude of the construction between $10,000,000 and $25,000,000. Performance and payment bonds will be required for the construction portion of the contract only. The tainter valves are located in the navigation lock at the referenced projects, inside the fill/drain culverts, at varying depths below the spillway deck. The main access is down the valve shaft via crane and basket. The tainter valves have an approximate size of 15 feet tall, 12 feet wide, and 19.5 foot in radius. The weight of each tainter valve is approximately 54,000 lbs. This project also includes the replacement of the associated mechanical equipment, including linkages, hydraulic cylinders, and hydraulic power units. The trunnion yokes, pins, bushing, and keeper plates shall also be replaced. The electrical systems will also be updated, which includes power and control for each of the valves. The work described herein involves the repair of four tainter valves and associated operating assemblies at each of the above referenced locks and dams. The contractor or their subcontractor who will be responsible for fabrication shall be certified under American Institute Steel Construction (AISC) quality certification program with one of the following certifications: Major Bridge Fabricator (CBR), Certified Bridge Fabricator - Advanced (ABR), Certified Bridge Fabricator - Intermediate (IBR), or Certified Hydraulic Fabricator (HYD). In addition to the above required certifications, the fabricator shall be certified with the Fracture Critical Endorsement (F). There are three major actions included in this contract scope of work: 1. Fabrication of the replacement parts 2. Removal of the existing equipment 3. Installation of the replacement equipment Only one pair of the tainter valves will be replaced at a time at each project, such that the other pair of valves on the project will remain fully operational to allow normal navigation movement through the lock. HLD-LMA-LGA-LLA Tainter Valves Combined Requirements Summary Scope of Work: Replace tainter valve trunnions for each replaced valve, including the bases, pins, bushings, anchor bolts and epoxy backing Rehabilitate the stainless-steel sealing surfaces in the culverts by performing weld repair and machining. Replace the lifting eyes for each tainter valve. Replace the entire linage assembly that connects each valve with its hydraulic operating cylinder. This includes the connecting rod and pin assemblies, crosshead assemblies, push rods and push rod guides. Replace both hydraulic operating cylinders. Replace the hydraulic power unit (HPU) for each tainter valve. This includes the motor, pump, tank and associated piping connections to the operating cylinder and electrical controls. Replace electrical components including the motor cables, thermal overloads, motor starter and circuit breaker, transformer, auxiliary relay, pressure and temperature switch, and time delay relays. Provide commissioning services to test the entire tainter valve system to verify satisfactory installation and operation. All on-site work shall be performed in accordance with the Corps of Engineers Safety and Health Requirements Manual (EM 385-1-1) The contractor will be responsible for establishing and managing an effective on-site Safety and Health program in accordance with EM 385-1-1 that will require the development and submission of a comprehensive project specific Accident Prevention Plan for Government acceptance. In addition, the contractor will be required to develop and submit for Government acceptance, and Activity Hazard Analyses for each phase of work and a project specific Fall Protection Plan that complies with EM 385-1-1. A site Safety and Health Officer (SSHO) employed by the prime contractor shall be required for each shift of the contractor'385-1-1s on-site operations. The SSHO shall possess a minimum of 5-years experience in construction safety on similar projects, shall have completed the 30-hour OSHA Construction Safety training within the last 5-years, and shall have completed at least 24-hours of formal safety training each year for the past 5-years. A qualified Fall Protection Competent Person shall be provided by the contractor for each shift of the contractor's on-site operations that involves work that exposes workers to fall hazards. This contract will require the contractor to furnish mobile crane equipment, crane operators, and rigging equipment that comply with the certification and testing requirements of EM 385-1-1. The contractor will be responsible for establishing and managing an effective Contractor Quality Control (CQC) System A CQC System Manager employed by the prime contractor shall be required to be on-site for each shift of the Contractor's operations. The CQC System Manager must possess a minimum of 5-years relevant experience in a supervisory or management position such as Quality Control Manager, Quality Assurance Manager, or Construction Manager directly involved in the management of construction quality at the project site. In addition, the CQC System Manager shall have completed the course entitled "Construction Quality Management for Contractors" within the last 5-years. The Contractor will be required to use the Government-furnished Construction Contractor Module (referred to as QCS) of the Resident Management System (RMS) to record, maintain, and submit various information throughout the contract period. QCS is a Windows-based program that can be run on a stand-alone personal computer or on a network. The Government will make the QCS software available to the Contractor after contract award. The project will involve the development and management of Contractor furnished submittals for items such as pre-construction plans, product data, test reports, and contract close-out documentation as required by the technical specifications of the contract. Miscellaneous work within the project includes the delivery of Record Drawings to the customer. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document.
