“3.3. DYNAMIC PILE ANALYSIS FOR STEEL PIPE PILES

A dynamic pile analysis shall be performed on the test piles in the location shown on the drawings. The Contractor shall not order and furnish any other pipe piles until the pile driving analyzer testing and review of the test report is complete, and the Government has provided the actual production pile lengths. The Contractor shall submit a performance report in pdf and MS Word format summarizing dynamic test results for test piles within 5 calendar days of completing field work. Dynamic testing provides supplemental information for evaluating pile integrity, hammer, and drive system performance, assessing pile installation driving stresses, and pile capacities.

Dynamic testing will validate the static testing results previously performed for the production piles. These results may require adjustments to the pile lengths. The pile load testing includes dynamic load tests with the results used to determine the pile length bid quantities. Two test piles will be tested for this project, both driven to EL. -108 at the location indicated on the contract drawings. Perform dynamic testing on the test piles during the full length of the pile driving (i.e., from the ground surface around EL. 0 to the end of driving) and during restrike a minimum of 14 days after initial driving. If the piles are spliced, the gauges shall then be installed on each pile segment. Upon completion of testing, the test piles shall be pulled and may be reused as production piles provided, they are cleaned, painted, in satisfactory condition as determined by the Contracting Officer, and do not require an additional splice. Provide equipment to obtain dynamic measurements, record, reduce and display its data that meet the requirements of ASTM D4945. The equipment must have been calibrated within 6 months prior to the start of the testing operations and thereafter throughout the contract duration. Drive test piles at the locations indicated.

The Contractor shall employ an independent inspection firm, hereinafter referred to as the “Contractor’s Geotechnical Consultant,” experienced in the pile driving process, monitoring of test pile installation, and in the use of the Pile Driving Analyzer and its related equipment. Perform dynamic pile analyses as follows:”

Award will be made as a whole to one bidder.

NOTE 1: Bidders shall furnish unit prices for each item listed in the Schedule requiring a unit price. If the bidder fails to insert a unit price in the appropriate blank for required item(s), but does furnish an extended total, or an estimated amount for such item(s), the Government shall deem the unit price to be the quotient obtained by dividing the extended amount for that line item by the quantity. IF A BIDDER OMITS BOTH THE UNIT PRICE AND THE EXTENDED

TOTAL OR ESTIMATED AMOUNT FOR ANY ITEM, ITS BID SHALL BE

DECLARED NON-RESPONSIVE AND THEREFORE INELIGIBLE FOR

AWARD.

* NOTE 2: Any bid may be rejected if the Contracting Officer determines in writing that it is unreasonable as to price. Unreasonableness of price includes not only total price of bid, but the price for individual line items as well. Any bid may be rejected if the prices for any line items or sub line items are materially unbalanced (See RFO 14.306-3, Rejection of Individual Bids).

NOTE 3: THE NOTICE TO PROCEED (NTP): The successful bidder is advised that performance and payment bonds shall be submitted in accordance with the time frame in block 12B of SF 1442. The NTP will be issued immediately after verification of acceptable performance and payment bonds. Within seven (7) days after issuance of the NTP, the Contractor shall initiate a meeting to discuss the submittal process with the Area or Resident Engineer or his authorized representative. Physical work cannot start until the Accident Prevention Plan, Contractor Quality Control Plan, and other submittals which may be required, have been submitted and approved and all preliminary meetings called for under the contract, have been conducted.

EVALUATION OF SUBLINE ITEMS (Dec 2019).

Item No. 0025 is subdivided into two or more estimated quantities and is to be separately priced. The Government will evaluate each of these items on the basis of total price of its subline items.

(End of Clause)

VARIATIONS IN ESTIMATED QUANTITIES - SUBLINE ITEMS (Dec 2019).

This variation in estimated quantities clause is applicable only to item No. 0025.

(a) Variation from the estimated quantity in the actual work performed under any second or subsequent subline item or elimination of all work under such a second or subsequent subline item will not be the basis for an adjustment in contract unit price.

*(b) Where the actual quantity of work performed for item No. 0025 is less than 85% of the quantity of the first subline item listed under such item, the contractor will be paid at the contract unit price for that subline item for the actual quantity of work performed and, in addition, an equitable adjustment shall be made in accordance with the provision entitled VARIATION IN ESTIMATED QUANTITY.

*(c) If the actual quantity of work performed under item No. 0025 exceeds 115% or is less than 85% of the total estimated quantity of the subline item under that item and/or if the quantity of the work performed under the second subline item or any subsequent subline item under item Nos. NONE exceeds 115% or is less than 85% of the estimated quantity of any such subline item, and if such variation causes an increase or a decrease in the time required for performance of this contract the contract completion time will be adjusted in accordance with provision entitled VARIATION IN ESTIMATED QUANTITY.
