times of sampling, on the Daily Report of Operations forms required in Paragraph "CONTRACTOR QUALITY CONTROL" of this section. Fax the hydrometer readings (expressed in Grams/Liter) daily to the US Army COE Philadelphia District Office, Operations Division, at 215-656-6922 or provide them directly to the Government Representative in the field. Collect each sample at the sluice from the mixture flowing over the discharge box interior weir as shown on the attached figure. Make a composite sample by partially filling, without overflow, a one-quart container for five or six consecutive intervals such that a total of about 1 gallon is collected and combined in a bucket or other suitable container. Determine the composite sample density by the hydrometer method, no more than 5 minutes after collecting the first one-quart container sample, otherwise discard the sample and make up a new one.

a. Hydrometer Method: The hydrometer used to determine the composite sample density shall be a soil hydrometer conforming to ASTM E100, Hydrometer No. ASTM 152H, -5 to +60 grams per liter. This specified hydrometer reads density directly in grams per liter, so no other computations are required to determine density. Submit the proposed hydrometer brand and model for approval prior to commencing dredging operations. Use the hydrometer as specified by the manufacturer.

b. Weight-Volume Method: When the weight-volume method is used for density determination, measure the total sample to obtain volume in liters and weight in grams. Measurements shall be made with a 1,000 c.c. laboratory cylinder and a scale or balance capable of weighing the sample and cylinder to the nearest gram. Obtain the unit weight by dividing the net weight of the sample in grams (total weight minus the weight of cylinder) by the total volume in liters.

3.3.4 Records

Submit records of disposal area effluent measurements and corrective action taken daily to the Contracting Officer.

3.3.5 Timber Flashboards

Prior to commencement of pumping, provide a sufficient number of flashboards for the sluice as required for the retention of dredged material under this contract and ensure that the entire sluice length is effective. Brush applied preservative treatment shall be available at the site and all cut surfaces shall be heavily brushed as specified in AWPA M4.

3.3.6 Continuing Effluent Control

Upon completion and acceptance of a work assignment, provide continuing, intermittent labor to ensure that effluent control is continued beyond the completion of dredged discharge into the disposal area. Continue the control, including the removal of flashboards, until water impoundment is reduced to that which existed prior to the commencement of disposal into this area. The time required for effluent control beyond completion and acceptance of the work assignment will not be considered part of the completion time for the contract.

3.4 OVERDEPTH AND SIDE SLOPES

3.4.1 Overdepth

Material removed from within a work assignment area, to a depth of not more

Section 35 20 23 Page 11 than 1 foot below the required depth, limited by a vertical plane through the required depth contour, will be estimated and paid for at the contract unit price for removal and disposal of material.

3.4.2 Side and End Slopes

No side or end slopes are specified for this contract. Dredging limits shall be box cut.

3.4.3 Excessive Dredging

Material taken from beyond the limits specified in the Paragraphs "Overdepth" and "Side and End Slopes", will be deducted from the total amount dredged as excessive dredging for which payment will not be made.

Nothing herein shall be construed to prevent payment for the removal of shoals performed in accordance with the applicable requirements of the Special Clauses "FINAL EXAMINATION AND ACCEPTANCE" and "SHOALING".

3.5 ESTIMATED QUANTITIES

The total estimated quantity of material necessary to be removed within the specified limits as shown on the contract drawings, including allowable overdepth and areas outside the turning basin limits as previously specified, is as follows:

3.6 LIMIT OF DREDGING

3.6.1 General

The areas to be dredged are within the contract limits as indicated on the contract drawings, and as specified in the Special Clause entitled: FINAL EXAMINATION AND ACCEPTANCE, and as defined by dredging prism indicated in the Paragraphs "OVERDEPTH AND SIDE SLOPES" and "MEASUREMENT AND PAYMENT", of this section.

3.6.2 Quantity Acceptance

Clear each acceptance section in its entirety to the required depth prior to acceptance of the work by the Government. If after-dredging surveys of a portion of an acceptance section indicate dredging is required, and it was indicated by the before-dredging surveys, remove required material found to be remaining above the required depth, unless such dredging is waived by the Contracting Officer. Material removed as a result of
