DESCRIPTION/SPECS./WORK STATEMENT

SPECIAL PROVISIONS

C.1. DESCRIPTION OF WORK.

The work covered by these specifications consists of furnishing all plant, labor, equipment and materials except for Corporation-furnished timber fenders and performing all work to repair approximately 50 feet of PZ-27 sheet piling anchored wall, known as the “North Wharf Wall” at the Spare Gate Storage Facility. A section of this wall that is approximately 40 feet long was displaced outward up to approximately 12 inches, when the bolted sheetpiling-to-waler connections pulled out through corroded sheetpiling material at certain locations. Behind the anchored wall, the granular fill has subsided. The work will require the Contractor to provide dry and stable access to both sides of the compromised sections of the wall. The repairs require the Contractor to clean, cut to sound steel, patch the steel sheets, move the wall back to its original alignment, make new waler connections to the repositioned wall and replace the granular fill behind the wall.

TECHNICAL PROVISIONS

C.14. SUBMITTALS.

SECTION C (Cont’d)

b. Contractor. The Contractor shall submit the following after contract award and prior to a preconstruction meeting:

3. A detailed safety plan to describe the measures to be utilized to insure that all aspects of the work are accomplished in accordance with OSHA Standards.

4. The work plan with shop drawings as necessary to provide detailed information shall be prepared, signed and sealed by a New York State licensed professional engineer. As a minimum, this document shall include cofferdam design and details (where proposed for wall access), detailed repair procedure, sheet pile to waler connection details, details of how existing storage pad pile foundations are to be stabilized and methods to be used in restoring the original sheetpiling bulkhead alignment.

5. Qualification/training certificates for divers and support personnel.

For the purposes of this specification, “approval” of submittals means that the Corporation has reviewed them for general conformance to the design concepts. “Approval” of any submittal does not relieve the Contractor from responsibility for proper workmanship, material conformance, dimensional accuracy and design adequacy for those elements not detailed on the contract drawings. The Contractor retains sole responsibility for dimensional accuracy of new fabrications and installations.

C.15. ANCHORED WALL REPAIRS.

a. General. The Basic Requirement Bid Items 1a. and 1b. are based on the premise that satisfactory repairs can be made by moving the displaced sheetpiling back to the original position and then restoring the failed waler connections at the sheetpiling. The sheetpiling shall be re-connected to the walers by reinforcing the connection areas in the sheetpiling web and then installing new bolts and other hardware as depicted on the contract drawings to complete the connection. It is assumed the waler and anchor tie rods and anchor wall are functional and will not require repairs. A 60 foot section of wall (designated as the “WORK AREA” and shown on the contract drawings) shall be cofferdammed or otherwise prepared so that all sheetpiling-to-waler connections within that section can be accessed for inspection and repair. Within that 60-foot work area, assume for bid purposes that 50 feet of wall containing fifteen (15) sheet piling-to-waler connections with two (2) bolts each will require restoration. The remainder of the connections within the 60-foot work area shall be inspected and any connections that appear close to failure or to have experienced significant sheetpiling thickness loss at the connection as determined by the COTR, shall also be restored as were the failed connections and paid for under Optional Requirement Bid Item No. 2a.

If, during the course of the work other deteriorated items, such as damaged/corroded walers, anchor tie rods or additional connections needing repair are discovered (beyond the designated fifteen (15) sheet piling to waler connections) and the COTR directs the Contractor to do this work, these repairs will be covered under either Optional Requirement Bid Items Nos. 2a. or 2b.

SECTION C (Cont’d)

b. Access. The sheetpiling-to-waler connections that require repair are normally below the waterline. They may best be accessed for repair by means of a cofferdam. It will be necessary for the Contractor to remove the existing timber fenders in order for the cofferdam to seal against the wall. Access to the sheetpiling-to-waler connections will also be required behind the wall (landward side). This will require excavation of the fill while simultaneously maintaining stability of the adjacent spare gate storage pad bearing pile foundations. It will be necessary for the Contractor to maintain a sump in the excavation or otherwise operate and maintain a dewatering system so that the work can be performed in the dry. To facilitate access by the Contractor, the Corporation will remove the spare gate sections from the two (2) easternmost towers.

c. Repair Procedure. In general the repair procedure will comprise the following steps:

1. The Contractor shall secure, expose and otherwise prepare a 60-foot section of the anchored wall encompassing the failed section as discussed above and shown on the contract drawings. Remove existing timber fenders as required, and then construct and dewater cofferdam, dewatering box or other mechanism as required to access the portion of the wall containing the connections to be inspected/repaired. The exact design, construction, installation, operation and maintenance of the cofferdam or other mechanism, stabilization system and dewatering system is the responsibility of the Contractor. The cofferdam/dewatering box must be able to withstand hydrostatic pressures, limit incursions of water into the dewatered area and provide adequate space for the work crews. The cofferdam could consist of a steel box or other type of structure sealed against the sheetpiling wall along the vertical sides and with a floor or possibly sealed into the bottom soils. Form-fitting flexible gasket material will reduce water leakage into the cofferdam. The Contractor shall maintain the work areas in a dewatered condition during repairs. The cofferdam/mechanism shall be designed, signed and sealed by a New York State registered professional engineer. The design shall be submitted to the COTR for approval.

2. Remove existing fill behind the wall as necessary to relieve lateral pressure, provide a work space and to provide a space to accommodate the wall as it is moved back to the original position. It will be necessary to maintain stability of the bearing H-pile supported spare gate storage pad foundations as the fill is removed. Contract Drawing No. SLS-340-73/2 shows a conceptual design for a method of maintaining existing foundation stability, but exact methods and details shall be the responsibility of the Contractor. The Contractor shall employ a New York State registered professional engineer to design the plan to maintain the foundation’s stability during the work. The design shall be included in the work plan submittal.

3. Move the displaced wall back to its original alignment as shown on the reference drawings. This could be done by pushing against an external reaction, jacking against the existing walers, jacking with a temporary external waler against the existing anchors or new drilled and grouted-in tieback anchors. The method shall be stated in the work plan submittals. The order the Contractor proposes to perform the work items (repair and reinforce, rebuild connections, move back to original alignment) shall be included in the work plan.

4. Repair and reinforce as necessary holes and weakened areas of the sheetpiling as necessary to provide a suitable bearing surface for the anchor connections. Details shall be provided in shop drawing submittals.

5. Rebuild the sheetpiling to waler connections following the concepts shown on Contract Drawing No. SLS-340-73/2. Shop drawing details shall be submitted for approval.

6. Place 2 inch minus crusher run crushed stone fill in accordance with Paragraph C.18 “Fill” behind the repaired wall to the level of the top of the sheetpiling. Care shall be taken not to overstress any part of the anchored wall system.

SECTION C (Cont’d)

7. Those connections within the work area that are not obviously damaged will be inspected by the COTR. The inspection will include a visual examination and ultrasonic thickness measurements of the sheetpiling material in the connection area in at least four (4) locations around the immediate perimeter of each washer plate. Those areas that are visibly deformed or have experienced significant thickness loss (25% or more) as judged by the COTR shall be repaired as described above.

8. Remove cofferdam, demobilize, etc. to restore the work area to original condition.

b. Methods and Materials. The exact methods and materials to accomplish the above shall be determined by the Contractor and shall be detailed in shop drawing and work plan submittals for Corporation approval per Paragraph C.14 “Submittals” above. They shall conform with the requirements of these specifications and/or approved work plan/shop drawing submittals. Materials and products not described in these specifications that will be part of the final project shall be submitted with the work plan submittals, which will form a part of the contract documents upon approval by the Corporation. In the event extra work is required per Optional Requirement Bid Items Nos. 2a. and 2b., the Contractor shall submit a work plan for these items to include materials and detailed procedures to conduct the repairs. Upon approval, this will form the basis of a contract modification under which the contractor will be compensated.

C.16. CONCRETE WORK.

a. General. If the Contractor chooses to incorporate concrete into the repair work that will remain in place, the concrete mix design shall be approved by the COTR and the concrete shall be placed and cured in accordance with all applicable American Concrete Institute (ACI) practices.

C.17. STEEL WORK.

a. General. This paragraph covers general requirements for steel work associated with repairs to the existing anchored wall. References made here to specific sections or subsections of the AWS D1.1 Structural Welding Code are based on the 2006 edition.

b. Materials. Materials shall be as shown on the contract drawings, approved submittals or described in the specifications for the specific work being performed.

7. Temporary and Tack Welds. Temporary and tack welds are subject to the same workmanship and quality requirements as for permanent welds and shall be made under the controlled conditions prescribed for permanent work.

8. Inspection by Contractor. The Contractor shall visually inspect all welds for workmanship and dimensional conformance. Completed welds shall be cleaned and carefully examined for insufficient throat or leg sizes, cracks, undercutting, overlap, excessive convexity or reinforcement and other surface defects to ensure compliance with the requirements of AWS D1.1. In addition, the Contractor must perform ultrasonic testing (UT) on all full penetration welding. Acceptance criteria for visual examination and UT are per AWS D1.1 requirements for cyclically loaded structures.

9. Defective Weld Repairs. Defective welds caused by the Contractor’s work shall be repaired in accordance with AWS D1.1, Subsection 5.26. or AWS D1.6. Defective weld metal shall be removed to sound metal by use of air carbon-arc gouging or by grinding. The surfaces shall be thoroughly cleaned before welding. Welds that have been repaired shall be retested by the same methods and acceptance criteria that were used in the original inspection. All costs of repairs and retesting shall be borne by the Contractor.

e. Bolted Connections. Bolts, nuts and washers shall be of the type specified or indicated. All nuts shall be equipped with washers except for high strength bolts. Beveled washers shall be used where bearing faces have a slope of more than 1:20 with respect to a plane normal to the bolt axis. Where the use of high strength bolts is specified or indicated, the materials, workmanship and installation shall conform to the applicable provisions of ASTM A325. Bolt holes shall be accurately located, smooth, perpendicular to the member and cylindrical. Bolt holes shall be drilled or subdrilled and reamed in the shop and shall not be more than one sixteenth (1/16) inch larger than the diameter of the bolt. Burrs resulting from reaming shall be removed. The threads of bolts shall be entirely outside of the holes. If the thickness of the material is not greater than the diameter of the bolts, the holes may be punched. If the thickness of the material is greater than the diameter of the bolts, the holes may be drilled full size or subpunched or subdrilled at least one eighth (1/8) inch smaller than the diameter of the bolts and then reamed to full size. Poorly matched or unfair holes will be cause for rejection. Drifting occurring during assembly shall not distort the metal or enlarge the holes. Subject to approval by the COTR, reaming to a larger diameter of the next standard size bolt will be allowed for slight mismatching.

b. Materials. Materials shall consist of No. 2 size crusher run limestone or equal which is 100% the product of crushing ledge rock at a quarry.
