PERFORMANCE WORK STATEMENT

PERFORMANCE WORK STATEMENT (PWS)

Fort Randall Dam Spillway Gates Nondestructive Testing

1.0 General Information.

1.1 Background.

1.1.1 Fort Randall Dam is located on the Missouri River near the town of Pickstown, South Dakota. The spillway is located on the left descending bank between the embankment and the powerhouse. The spillway flows are controlled by 21 radial Tainter gates which are 40 feet wide by 31 feet high. The Tainter gates were constructed in 1952 and 1953. The structural steel was specified as Federal Spec QQ-S-741 Grade A, Class I, Type II which has specified minimum yield stress of 32 ksi, minimum tensile strength of 58 ksi, and weldability similar to ASTM A36.

1.1.2 In 1998, ASTM A36 structural steel plates and shapes were welded to the gate arm struts to increase capacity for loads due to wave action and trunnion bearing friction. Structural steel diagonal braces were welded to the end frames to resist forces caused by trunnion bearing friction and wave action.

1.1.3 In 2014, a painting contract was awarded that also required a Certified Weld Inspector (CWI) to perform visual inspections of all fillet welds and a technician certified for ASNT SNT-TC-1A for Level II to perform magnetic particle testing (MT) of fillet welds with paint removed. A few fillet welds were not accessible for MT.

Cracked fillet welds on fracture critical members were excavated and repaired. Numerous fillet welds were reported to be undersized or to have some minor degree of undercut or lack of fusion. Because the fillet welds with minor deficiencies such as undersize, undercut or lack of fusion have relatively low stress they were judged to not be a priority for repair.

1.1.4 The 2014 contract also required a technician certified for ASNT SNT-TC-1A for Level II to perform ultrasound testing (UT) of complete joint penetration (CJP) welds with paint removed. The UT observed lack of fusion and/or incomplete penetration in almost all of the CJP welds.

1.1.5 The 2014 inspection observed corrosion with section loss on the bottom surfaces of the trunnion girder anchor flanges near their embedment in concrete.

1.1.6 The 2014 inspections noted that the cast-steel trunnion hubs were observed to have highly irregular surfaces.

1.1.7 At the connections of skinplate assemblies to the upstream flanges of the girders, erection bolts were removed and the holes filled with weld metal (herein referred to as plug welds). The 2014 MT of base metal surrounding the plug welds did not report any cracks. No attempt was made to use ultrasound to test the interior of the weld metal or the fusion zone.

1.2 Scope of Work. This is a non-personal services contract to provide nondestructive testing, paint removal and touchup painting on two of the Fort Randall Dam Spillway Gates with the options to test two more. The intent of this contract is to more accurately determine sizes and locations of previously reported flaws in the Spillway Gates at Fort Randall Dam so that a Fitness For Service (FFS) analysis may be performed by the government to determine if the defects need to be repaired. NDT methods will include visual inspection, shear wave ultrasound, phased array ultrasound, magnetic particle testing, and dye penetrant testing. Work will also use phased array ultrasound to measure extent of loss due to corrosion of steel plates where plates are embedded in concrete. Testing will require removal of vinyl paint at the locations to be tested and re-coating with a vinyl paint system. Work will be on the downstream side of the gates with the gates closed. Shielding of work areas from gate seal leakage may be required.

Access to the locations to be tested will require spillway apron access. After NDT testing has been performed, reports of the NDT results of the gates are to be submitted. The government shall not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the contractor who, in turn is responsible to the government. This is a firm fixed priced, performance based service contract where the government defines and measures desired outcomes, while contractor methods are generally not constrained or directed.

1.3 Period of Performance: The period of performance shall be 240 days not to include the winter exclusion period in paragraph 1.3.1.

1.3.1 Winter Exclusion Period: No work will be required at the site during the period of 01 November through 01 April inclusive. The days in this period have not been included in computing the calendar days for completion of the work. If the Contractor wishes to perform work during this no work period, they shall prepare and submit a cold weather work plan for approval by the Contracting Officer. The cold weather work plan shall detail the Contractor's means and methods for ensuring quality of work during severe weather and cold ambient temperatures. Approval for work during this time is not a guarantee and the determination will be made by the Contracting Officer based on the details of the Contractor's cold weather work plan. No time extensions will be granted for delays during this period.

1.4 Contractor Personnel

1.4.1 The contractor shall perform the preponderance of work under this contract using his or her own forces except as provided in Paragraph 1.4.2 Subcontracting. Employees who perform this work shall be qualified persons on the contractor’s own payroll. Personnel are required to be at least 18-years old and qualified to perform the work.

Prepare all surfaces to be painted in accordance with the coating manufacture product data application instructions. The finished coating must be free from holidays, pinholes, bubbles, runs, drops, ridges, waves, laps, excessive or unsightly brush marks, and variations in color, texture, and gloss. Apply each paint coat in a manner that will produce an even, continuous film of uniform thickness. Brush strip edges, corners, crevices, seams, joints, and other surface irregularities for each coat applied to ensure they receive an adequate thickness of paint. Submit Paint Application Procedure for field touch-up activities. Include containment, environmental protection, surface cleaning, temperature requirements, mixing, thinning, spray/brushing equipment, recoat and dry times, and measuring film thickness for each procedure.
