W9123822R0031 FOLSOM DAM - HCR FOX HVOF RODS REPLACEMENT The Government anticipates issuing a Request for Proposal (RFP) with the intent of awarding a Firm-Fixed Price construction contract for the Folsom HCR Rods Replacement. Project Description: This project replaces existing hydraulic cylinders and rods for Flood protection spillway gates due to early signs (cracking of top coating) of advanced corrosion. The scope of work will include deconstruction of the (12) existing hydraulic cylinders and removal of the spare cylinder, manufacturing, transporting, providing off-site storage for up to two years, installing and testing twelve (12) replacement hydraulic cylinders assemblies and providing one spare, and integrating the control system. The existing cylinder rods are 8-inch in diameter and 40 feet long. The design of the new cylinders and rod systems will be of a performance-based requirement and need to accommodate existing structure tolerances. The replacement hydraulic cylinder assemblies must be compatible with the existing gate connection points, cylinder trunnion supports, hydraulic cylinder connections for power, controls, hydraulic fluid piping, and rod position system power and signal wiring as well as the PLC input card. The new hydraulic cylinder rod coating will be laser cladding/weld overlay over groove-based hall-effect contactless linear measurement sensor and transducer for position measuring system. A critical aspect of the hydraulic cylinder assembly design is thorough quality assurance/quality control (QA/QC) procedures during manufacturing, transportation, installation, control system integration and cylinder testing. The construction scope of work will include performing on-site existing condition assessment and survey, protection of existing concrete spillway and concrete piers during construction, deconstruction of existing hydraulic assemblies from a gate in the fully closed position, replacement of hydraulic cylinder assemblies with new hydraulic cylinder rod position measuring system linked to the rod design, clean existing hydraulic fluid (550 gallons per gate), re-wire the new cylinder rod position measuring system to the existing PLC input card, update the PLC program to recalibrate the position measuring signal and make use of the non-volatile memory, install new 24-hour uninterruptable power supply (UPS), and perform dry and wet testing of gates. The Contractor is responsible to remove and recycle or dispose of 13 existing hydraulic cylinders and rods. In accordance with DFARS 236.204(i), the estimated magnitude of construction is expected to be between $10,000,000 and $25,000,000. This prospective contract action will be conducted using NAICS Code 237990 (Other Heavy and Civil Engineering Construction). The size standard is $39,500.00. Product Service Code is Y1PC (Construction of Other Non-building Facilities). The solicitation will proceed as a full and open competition and is estimated to be issued on or about 9 May 2022, with proposals due tentatively on 21 June 2022. The RFP will be issued on the Government Point of Entry known as sam.gov and will establish a firm proposal due date/time. If applicable, the site visit date, time and location will be identified in the solicitation. BE ADVISED THAT THIS PROJECT MAY BE DELAYED, CANCELLED OR REVISED AT ANY TIME DURING THE PRE-SOLICITATION, SOLICITATION, SELECTION, EVALUATION, NEGOTIATION AND/OR FINAL AWARD PROCESS. The only INTERESTED VENDORS LISTS (plan-holder's/bidder's list) is available via SAM.gov. Contractors are responsible for self-identifying as interested vendors and viewing other interested vendors. Contractors should check sam.gov frequently for any changes to the interested vendors list and notice.
