Lower Monumental Navigation Lock Downstream Gate Hoist Machinery Upgrades

Added: Jun 19, 2015 8:19 pm The work described herein involves the replacement/upgrade of the navigation lock downstream gate hoist mechanical machinery and the associated electrical and control equipment, and the rehabilitation of the gate hoist friction sheaves.

Mechanical upgrades consist of the hoist drive components required to operate the gate, the overhead service crane in each machinery room, and the mechanical aspects of limits and controls for gate operation.

Furnish and install the following items for the hoist drives in each machinery room: new pinion gears, pinion shafts, pinion bearings, couplings, and brakes. In addition, install new Government-furnished gearboxes.

Install new bearings for the friction sheaves in each machinery room. In order to replace the friction sheave bearings, the contractor must have technical experience, labor, and physical plant required for jacking and shoring of the existing 18 foot diameter friction sheaves that weigh approximately 112,000 pounds each. Upon completion of the bearing replacement, the contractor will be responsible for precise alignment of the friction sheave bearings and the alignment of open gear contact between the new pinion gears and the existing friction sheave ring gears.

The contractor will be responsible for gate hoist wire rope load balancing that will require the services of a qualified engineer with a minimum of three years experience with load cells and load monitoring equipment to ensure the loads are evenly distributed across all hoist wire ropes at the completion of the work.

The overhead service cranes in each machinery room will be replaced with commercially-available five ton rated electric wire rope hoists. New overhead cranes shall be single-girder top running bridge-type furnished with pendant style pushbutton remote control and wall-mounted pushbutton control station.

Structural upgrades consist of rehabilitation and weld repair of the downstream gate hoist friction sheaves, fabrication and installation of new machinery supports and pedestals, fabrication and installation of new work platforms, gratings, handrails, guardrails, ladders, and ladder cages, and structural modifications to the existing overhead service crane corbels.

All weld repair performed on the gate hoist friction sheaves must conform to American Welding Society (AWS) D1.5 - Bridge Welding Code requirements. Accordingly, contractor welders shall pass the qualification tests prescribed by AWS D1.5 prior to performing work on this contract. Develop welding procedures in accordance with AWS D1.5 and provide the services of AWS D1.5 certified welding inspectors to conduct required non-destructive testing of new and repaired welds on the gate hoist friction sheaves.

Structural modifications to the existing overhead service crane corbels consist of the installation of an adhesive anchor system to increase the load capacity of the corbels from 5,000 pounds to 7,000 pounds. Evaluate concrete drilling locations for the presence of existing reinforcing steel with Ground Penetrating Radar or an approved equivalent method.

Electrical upgrades consist of replacement of the machinery room motor control centers and power supply wiring and circuit breakers, installation of new variable frequency drive (VFD) equipped motors, new main power disconnects, new power distribution blocks, new VFD's, new control voltage transformers, new dynamic brake resistors, new programmable logic controllers (PLC), new network switches, new fiber optic panels, and new control relays.

New PLC installations require the contractor to provide PLC program development, licensed software packages, shop testing, and operator field tests. New VFD installations require specified hardware, programming software, onsite installation supervision by the VFD manufacturer, VFD test plans, and execution of performance verification tests.

New control panel, graphic panel, and equipment panel installations require specified hardware to be verified through Government-witnessed shop testing prior to delivery to the work site.

A critical element of the project involves complex sequencing and coordination of commissioning and cut-over of new equipment and systems, and highly technical interfaces between new and old systems. The Contractor must demonstrate experience and qualifications necessary to manage challenging Quality Control and Commissioning programs for both factory and on-site testing requirements. The project involves the procurement of complex electrical and control equipment with long lead times. Complete on-site work in close coordination with the Government lock and dam facility, and minimize outages and disruptions to operations.

Provide on-site customer operations and maintenance training by authorized representatives of the new equipment manufacturers.

Miscellaneous elements of the contract include RCRA 8 metal based paint and asbestos containing material (ACM) removal and disposal from existing equipment.

The construction magnitude is estimated between $1,000,000 and $5,000,000. 100% performance and payment bonds will be required. NAICS code for this project is 237990, and the small business size standard is $36,500,000 average annual receipts.

Solicitation No. W912EF-15-R-0048 will be posted to the FBO website on or about August 4, 2015. Solicitation is open to small business concerns only. The proposal due date will be contained in the solicitation and any solicitation amendments that may be issued.
