Carefully control unwatering of work areas within cofferdams to protect stability of thecofferdams, slopes, and foundations.I. The fish screen footprint and cofferdams within the Sacramento River shall be unwateredto the base of the excavation continuously until all disturbed material has been removedfrom the base of the excavation and the excavation limits have been approved by theCOTR, All cofferdam leakage and ground seepage shall be removed by the unwateringsystem to prevent ponding of water.J. After the fish screen excavation has been approved by the COTR, the unwatering systemshall prevent ponding of water on the surface of the excavation until the floor slab hasbeen completed and the Contractor has taken such measures as are needed to preventuplift pressures on the slab foundation. Ponded water can then be allowed to a maximumdepth of 1 foot above the top of the slab, provided all concrete work has been completedto a distance of 2 feet above the slab. Ponded water shall not exceed a depth of 2 feetabove the slab until the concrete deck is completed.K. Unwater as required to remove water from surfaces to receive concrete.L. Continuously maintain unwatering to the base of the excavation for the approachretaining walls, all other retaining walls, anchorage systems, and all excavation until allbackfill has been placed and compacted or until approval to remove the system is givenby COTR.M. Reflood work areas within cofferdams, braced excavations, open excavations, or canalsin a controlled manner to protect structure from uplift due to river or groundwater rising.Remove water to resume work at no cost to the Government.N. Ponded water may be trapped in low areas between cofferdams and will require removalbefore surface work within the areas.O. Where surface runoff discharges into excavations, divert or collect these discharges andpump to acceptable discharge points prior to the water entering excavation.P. Meet requirements of Section 01 57 30 - Water Pollution and Erosion Control fordischarges from unwatering facilities.Q. Backfill ditches excavated below final lines and grades shown on drawings to theestablished lines and grades shown with materials conforming to gradation andcompaction requirements specified for adjacent materials.R. When the horizontal portion of the forebay excavation is complete, sufficient unwateringshall be performed to remove all water to a depth not to exceed 2 feet to allow surveying.3.05 CONTACT WATERA. Removal of Water Plan shall include methods and procedures for collection, storage,testing, and disposal of all contact water.Removing and Controlling Water During Construction31 03 33 - 12

Amendment 0005Red Bluff Pumping Plant and Fish Screen Specifications No. 20-C0752B. Testing for characterization shall include tests listed in Table 31 03 33A - WaterAnalyses.C. As the characterization of the water cannot be predicted in advance, for bidding purposesall Contact Water will be assumed to require transportation to the City of Red Bluffwastewater treatment facility or other appropriate facility for disposal.Table 31 03 33A - Water AnalysesAnalytical Methods for Waste CharacterizationVOCs (SW8260B) 40SVOCs (SW8270C) 40TPH Gasoline, Diesel, and Motor Oil(SW8015M)Title 22 Metals (SW6010B/7471A) 40PCBs (SW8082) 40Dioxins and Furans (SW8290) 40Pesticides (SW8081A) 40Herbicides (SW8151) 40Estimated Number ofSamples403.06 REMOVALA. Remove equipment following ending of operations.B. Remove equipment from the site, including standby and spare equipment and temporaryelectrical supply.C. Fill and seal wells, deep wells, well-point wells, monitoring wells, and spare wells, inaccordance with State of California, Tehema County, and local well abandonmentregulations and the following:1. Attempt to pull and remove the entire casing-screen string and allow the filtermaterial to collapse into the hole.2. Seal the hole by tremieing cement grout from the bottom of the hole up to thelevel of the bottom of the excavation.3. If entire casing-screen string cannot be removed, attempt to pull and remove thecasing by separating it from the screen at the disconnect joint. If this cannot bedone, abandon the entire casing-screen string in the hole, except as requiredbelow. Seal and fill wells as required above.Removing and Controlling Water During Construction31 03 33 - 13

Amendment 0005Red Bluff Pumping Plant and Fish Screen Specifications No. 20-C07524. Cut off casing remaining in the hole not less than 3 feet below ground surface.Backfill and compact hole with clean sand or other approved material.5. If a well discharges by artesian flow, stop flow before sealing and fillingoperations by pumping from remaining wells or by placing cement grout at a ratesufficient to prevent grout dilution or displacement. Allow a minimum of 48-hourgrout set time before doing additional work in the hole.6. Remove drain pipes associated with sumps or other dewatering activities. If drainpipes can not be removed, backfill and abandon them in accordance withrequirements above.7. Backfill and compact with native materials sumps, trenches, and holes.8. When a conflict arises between the above requirements and State or localregulations, the most stringent regulation/requirement shall apply.3.07 REPAIRSA. Repair or replace damage to the work resulting from negligence, inadequate performance,or mechanical or electrical failure of dewatering or unwatering system components.1. Damages to the work include work in place and excavation.2. Damages may be due to, but are not limited to, bottom heave or flotation.B. Remove and replace damaged materials as approved by COTR.3.08 RIVER SCOUR PROTECTIONA. Prior to installation of cofferdam for fish screen or placement of any riprap in the river,make a bathometric survey with 1 foot contour intervals of the area of the river from theplanned face of the cofferdam out 20 feet into the river. Extend survey 200 feet upstreamand downstream fro the ends of the cofferdam. Tie bathometric contours to aboveshoreline contours shown on the project topographic map.B. Protect full width of river bottom from scour due to temporary construction worksincluding cofferdam, excavation and other work in the river and along the shoreline.Repair scour areas as approved by COTR. Repeat bathometric survey after scour repairhas been completed.END OF SECTIONRemoving and Controlling Water During Construction31 03 33 - 14
