The contractor shall remove and replace the wide-flange beam and various structural components in the following proposed order. Prior to the start of work, the government and contractor will agree on the order work shall be completed:

1) The government will operate the gate into the opened or recessed position. From here, the contractor can enter a pit to access the work area, or work can be done via a barge and scaffolding from the water. Confined space entry permits are required to access the gate pocket. Air monitoring is required if hot work is performed as oxygen levels may diminish.

2) The contractor shall secure the gate in the opened position via anchors in the top of the concrete wall and come-alongs attached to the gate. The contractor shall coordinate with the government to establish two separate anchor points. Each anchor point shall be capable of supporting a minimum 4 tons of force.

3) Remove the single section of timber fender and steel channel on the outside (water side) of the gate. The channel is welded to the gate. Set aside as the channel and fender shall be replaced later.

4) Block the 8” diameter hydraulic cylinder in the rear under the house. This will prevent damage to the cylinder and the clevis from rising when it is disconnected in the next step.

5) Disconnect the twelve (12) 7/8” diameter rods which secure the clevis to the wide flange beam. Four (4) of these rods penetrate through the outer bulkhead plate. Discard bolts.

6) Coordinate with the government to fully retract the cylinder, pulling it away from the W14x90 beam. The contractor shall expect only a fraction of an inch of retraction. The cylinder cannot be moved from here unless the body is unbolted, hydraulic lines disconnected, and physically moved back. Retain the steel shim plate for reuse.

7) On the outside or water side of the gate, there is a large plate known as the bulkhead plate. The bulkhead plate is approximately 8’ 8 ½” x 3’ 10 3/8”, and there are two layers of it, along with a filler plate between the inside layer and the beam. At each side of the bulkhead plate to be removed, there are 10” wide vertical plates to be removed which secures the bulkhead plate. At the pivoting side of the gate, there are two layers of plates. The outer plate is a 10” x 1” plate, which can be removed and set aside for later reuse. The inner plate is 10” x 5/8” and runs the full height of the gate. The plate shall be cut just below where the bulkhead plate to be removed is. The top of the 10” plate shall then be unbolted from the gate and disposed of, while the lower section of this plate shall remain. There is a variety of solid rivets and bolts which shall be removed. Retain the other 10” x 1” vertical plate as it shall be reinstalled later. Dispose of the removed rivets and bolts, as longer ones will be required later.

8) Remove the rivets on the angles at the top and bottom of the bulkhead plate. These angles will be replaced with new angles, of an equal size, galvanized A36 steel. Refer to the drawings for angles to be replaced.

9) Remove the W14x90 beam and recycle off-site. Care must be taken not to damage the hydraulic cylinder.

Any damage to government property shall be repaired or replaced by the contractor at the contractor’s expense.

10) In each side of the gate pocket, there are steel plates, known as diaphragm plates. Remove the diaphragm plates and angles as shown in the drawings. Recycle the plates and angles off-site.

11) Drill two (2) new 15/16” holes in both the clevis eye mounting and shim plate. The plate shall be modified in place, as removal of the plate includes removing the pressed-in pin from the bearing inside the clevis eye. One hole will go in each the top and bottom row of bolts. Two (2) new 7/8” bolts will be added later, for a new total of fourteen (14) bolts to secure the plate to the beam.

12) The government will inspect all work and determine if demolition is complete. The new plates and beams shall not be installed until government approval is given.

13) Apply two (2) coats of cold galvanizing compound to any areas where paint has been damaged or surface modified.

14) Insert the two (2) new diaphragm plates onto each side of the beam, including angles. The diaphragm plates are approximately 3’ 11 5/8” x 3’ 5/8” x 3/8”. Bolt the perimeter of each plate to the new angles using 3/4” hex head bolts. Use a direct tension indicating washer and tighten until dye is seen.

15) Insert the new W14x211 beam from the water side of the gate and secure to the vertical angle with 3/4” hex head bolts. Use a direct tension indicating washer and tighten until dye is seen. Verify proper mounting location as the hydraulic cylinder clevis eye mounting plate will later be joined to this. There is some small play allowed in the two axes of the hydraulic cylinder assembly.

16) Insert the bulkhead plate and bolt to the flange of the beam and the angles, using 1” bolts. The bolts shall be installed with 1” tension-indicating washers. Install a structural washer between the tension-indicating and nut or bolt head. Tighten until indicating dye is seen.

17) Install the new 10” x 5/8” vertical plate on the water side of the gate using new bolts, length to be determined by the contractor. Install the existing 10” x 1” plate which was removed and set aside earlier. New A325 bolts are required. The contractor shall determine the length of fasteners required, as there is now extra thickness and a longer length is required than what was removed. Use a direct tension indicating washer and tighten until dye is seen.

18) The government will extend the hydraulic cylinder for the clevis eye mounting plate to meet the beam. Insert the shim plate that was removed earlier. The nuts shall be on the hydraulic cylinder side. Use thread locker on the nuts.

19) Bolt the mounting plate to the beam using 7/8” bolts. Install a 7/8” tension-indicating washer. Install a structural 7/8” washer between the tension-indicating and nut or bolt head. Tighten until indicating dye is seen.

20) The government will perform a joint inspection with the contractor.

21) After inspection acceptance is given, reinstall the timber fender and steel channel by welding the channel back to the gate.

22) Remove the come-alongs securing the gate.

23) The government will operate the gate and perform a final inspection with the contractor to ensure work meets the contractual requirements.

The contractor shall supply to the government red-lined construction drawings as part of a project closeout submittal.

Payment for this line item will be one lump-sum payment when the final inspection is accepted by the government.
