Reinforcement and embedded metalwork shall be accurately placed and maintained in position during concrete placing and vibrating. Welding of reinforcing bars, including tack welding, shall be in accordance with AWS D1.4 (1996). Welding procedures and electrode requirements shall be based on a mill report on the reinforcing bars to be welded. Mill reports shall be obtained from the bar manufacturer and shall be available for inspection at the jobsite during welding work.

(4) Tolerances. -- Dimensional tolerances shall be in accordance with PCI MNL-116. (5) Finishes. -- (a) Standard underside finish. -- The finish shall be produced by smooth, clean forms such as steel- or plastic-lined forms. Normal color variations, small surface holes caused by air bubbles, and minor form marks will be permitted. Major spall, honeycombing, or structural defects will not be acceptable. (b) Standard top finish. -- This finish shall be produced by using a vibrating screed or unformed surfaces, with hand finishing to flatten projections. Normal color variations, minor indentations, and minor chips and spalls will be permitted. Major imperfections or honeycombing will not be acceptable. (c) Broom finish. -- Floating may be performed by use of hand- or power-driven equipment. Floating shall be started as soon as the screeded surface has stiffened sufficiently, and shall be the minimum necessary to produce a surface that is free from screed marks and is uniform in texture. Joints and edges of slabs and other joints and edges shall be tooled where shown on the drawings or as directed. Light broom finish shall be applied after floating has been performed. Broom marks shall be parallel to the direction of traffic. (d) Ends of prestressed units. -- (aa) Nonexposed ends. -- Strands shall be recessed and the ends of the strands coated with a suitable protective bituminous material.

Epoxy mortar shall be mixed from the proper color fine aggregate and cement so that the patching will match the end of the unit. The surface of the epoxy mortar shall be ground to match the color of adjacent concrete. Patching which does not match the end of the unit in color and texture shall be removed and replaced. (6) Curing. -- Units shall be cured by steam, radiant heat, or water curing. Curing compounds, sealers, or coatings shall not be used for curing. (a) Steam curing. -- Immediately after casting, units shall be enclosed to prevent escape of moisture. Enclosures shall not contact the concrete or its immediate formwork to allow full circulation of the saturated vapor around the concrete. The ambient temperature under the enclosure and about the units shall be between 70 and 100 degrees Farenheit for at least 3 hours after completion of concrete placement. Thereafter, the temperature shall be maintained between 120 and 160 degrees Farenheit until the required strength is attained. The ambient temperature rise about the units shall not exceed 40 degrees Farenheit per hour. Following the curing period, the concrete shall be protected from rapid drops in temperature which may damage the concrete. (b) Radiant-heating curing. -- Radiant heat shall be applied to units immediately after casting by pipes circulating steam, hot oil, or hot water, or by electric blankets or heating elements. Pipes, blankets, or heating elements, shall not contact concrete formwork or test cylinders. During radiant-heat curing, rapid loss of moisture in any part of the concrete unitshall be prevented. Moisture may be applied by a cover of moist burlap or cotton matting. Moisture may be retained by covering the unit with an insulating cover or other tight enclosure which will promote even application of heat and prevent loss of moisture. Ambient temperatures about the units shall be maintained as specified for steam curing. (c) Water curing. -- Units shall be cured as soon as the concrete has attained sufficient set to prevent detrimental effects to concrete surfaces. Water curing shall be accomplished by covering the concrete with water-saturated material or by applying moisture using a system of perforated pipes, mechanical sprinklers, porous hose, or other methods approved by the Contracting Officer, which keep exposed surfaces continuously wet until the required strength is attained. Units shall be continuously cured until the design strength is ensured; however, curing shall not be discontinued until concrete has reached 500 pounds per square inch less than the design strength. Curing time shall be adjusted, based on specified concrete testing, to ensure that the units meet specified design strength. (7) Testing. -- Concrete shall be tested by the manufacturer in accordance with PCI MNL-116 and the test results shall be sent to the Bureau of Reclamation, Pacific Northwest Construction Office, PO Box 2967, Yakima WA 98907-2967. Units shall not be shipped until specified test results have been received by the Government. (8) Shop cleaning and protection of metalwork. -- Exposed surfaces of welding plates shall be cleaned of loose mill scale, loose rust, weld slag, dirt, and other foreign matter. Cleaned surfaces shall be protected by a method which permits safe effective welding, prevents rust stains on the concrete. Petroleum-based products, silicone oils and greases, and materials which would produce toxic fumes during welding shall not be used. (9) Marking. -- Units shall be marked in accordance with the approved drawings. Identifying marks shall not be applied to concretesurfaces which will be exposed to view after erection. h. Inspection. -- Government representatives and the Contractor will jointly inspect the first production units with standard top finishes at the manufacturing plant. At least 14 days before curing is completed for the first units with theses finishes, the Contractor shall notify the Bureau of Reclamation, Pacific Northwest Construction Office, PO Box 2967, Yakima WA 98907-2967, of the date that curing of these units will be completed. The Government will arrange these inspections. i. Handling, delivery, and storage. -- Units shall be lifted and supported at the lifting and supporting points indicated on the approved drawings during manufacture, transportation, storage, and erection. Units shall be delivered to Tieton Dam located on the Tieton River about 32 miles northwest of the City of Yakima, Washington, approximately at mile post 166 of Washington State Highway 12, as shown on Drawing No. 33-100-2754 and Drawing No. 33-100-2753. The exact date, time, and location of delivery shall be coordinated with the construction contractor. The precast manufacturer will be responsible for delivering the units to the above location. The construction contractor will offload the units from the delivery truck. The name, address, and telephone number of the construction contractor will be provided by the Government when available. Units shall be stored off the ground and separated by battens at each bearing point. Lifting devices shall be accessible and undamaged. II.
