Fabrication of Vertical Lift Gates, Montgomery Locks and Dam

The Pittsburgh District of the U.S. Army Corps of Engineers has a need for the fabrication and delivery of two Vertical Lift Gates for The Montgomery Locks and Dam located approximately 31.7 miles downstream from the Point at Pittsburgh, Pennsylvania. Fabrication of the lift gates includes idler sprockets, drive sprockets, and chains for each gate fabricated. The contract also covers fabrication and delivery of machinery support beam pedestals for the existing operating equipment for each gate that is fabricated. Installation of the gates will be performed separately.

The gates and machinery pedestals will be constructed using various sizes of steel shapes and steel plate. The majority of the steel items will conform to ASTM A992 Grade 50 and ASTM A709/A709M Grade 50F. In addition, there are several stainless steel items including pins, roller and wheel components, and seal plates. Connections will be accomplished by a combination of welding and bolting. All welded joints are welded in accordance with AWS D1.5 and are to be tested by applicable non destructive testing (ultrasonic, magnetic particle, and visual). After fabrication and before cleaning, metalizing and painting the gates will be thermally stressed relieved in accordance with AWS D1.5.

Each gate is comprised of a central leaf section and two end truck sections. The leaf section is a three dimensional welded truss system with a front skin plate. The leaf is approximately 14 feet high by 12 feet wide by 100 feet long. The end trucks are plate weldments approximately 14 feet high, 6 feet wide and 4 feet deep with an attached wheel assembly. The gate is metalized and painted, has access platforms and ladders, and weighs approximately 130 tons. The gate leaf and trucks will be shop assembled for inspection, then disassembled and shipped. The gate leaf is to be delivered in one piece; field assembly will not be accepted. The machinery pedestals are built-up sections comprised of wide flange sections and plates and are approximately two feet wide by 4 feet long by 6 feet high.

Components of the gate include the framing, skin plate, diaphragms, diagonals and gussets, fenders, seals, wheels, rollers, grease systems, miscellaneous machined parts, walkway framing, grating, handrails, and associated accessories. The contractor will be responsible to develop and submit detailed shop drawings for review and approval.
