3.2 EXCAVATION

3.2.1 General

Contractor's equipment mobilized to the project site for excavation shall be suitable for excavation in the borrow area shown in the plans and capable of dredging at the borrow areas maximum depth.

3.2.2 Borrow Area Characteristics

The characteristics of the materials in the borrow areas may be as generally indicated by the sediment boring logs and grain size distribution curves area located in Section 00 31 32 GEOTECHNICAL DATA REPORT (GDR).

The descriptions of the material found within the GDR are based on the site investigations and core borings and only describe the materials obtained from those investigations. The Contractor is solely responsible for any interpretation or conclusions drawn therefrom. The Contractor may visit the location to view the core samples prior to the start of construction. The Contractor shall provide a five (5) day notice to the Contracting Officer or their represent agent of their requested visit. The material found in each of the borrow area sediment core borings (vibracores) is indicative only of the sand at that discrete location. The CONTRACTOR should be aware that it is possible for material of differing characteristics to be present in the borrow areas, including material differing from that contained in the vibracores.

3.2.3 Borrow Area Dredging

The borrow area and each subdivision selected by the Contracting Officer for excavation shall be completely excavated within reasonable limitations before relocating the dredge to another borrow area. Excavation shall be performed in a uniform and continuous manner so as to avoid creating multiple holes, valleys, or ridges. The borrow area shall be dredged to maximize the removal of sand from each sub-area of each provided borrow area. The purpose of this requirement is to avoid "wasting" sediment which could be used to renourish the beach now and in the future. The Contractor is not permitted to dredge within the dredging exclusion zone unless otherwise directed by the Contracting Officer.

3.2.4 Overflow Dredging

Overflow is considered a part of the dredging process and is permitted to occur within the borrow site during loading to the extent that turbidity and water quality standards required by Sections 01 57 20 ENVIRONMENTAL PROTECTION and 01 57 25 TURBIDITY AND DISPOSAL MONITORING are met.

3.2.5 Borrow Area Excavation Limitations

All excavation shall be performed within the horizontal and vertical limits of the borrow areas shown in the drawings. Under no circumstances shall excavation occur below the designated tolerance limit of excavation as shown in the drawings. No dredging is permitted in excess of the dredge depth shown in the drawings, referenced to NAVD88. Additionally, the Contractor shall not disturb the sediment in any manner below the depth of allowable disturbance which is one (1) foot below the maximum target depth of excavation. The material located below the indicated allowable tolerance depth is of unknown quality and may not be suitable for beach

GROUP4-10-R-0027 SECTION 35 20 25 Page 17 Revision 0005 renourishment. The Contractor will be required to certify in each Daily Quality Control Report that the excavation was conducted in compliance with the Drawings and Specifications including excavation and sediment tolerance depth.

3.2.6 Unsuitable Material

If continuous reaches of rock, clay or other unsuitable materials or unacceptable materials as defined in the paragraph titled "QUALITY CONTROL FOR BEACH FILL" are encountered in the borrow area, the Contractor shall change the location and depth of excavation within the borrow limits when necessary to provide the best fill material available at no additional cost to the Government. The location of unsuitable material encountered within the borrow area shall be noted on the Contractor's Quality Control Report (copy appended to the end of Section 01 45 05 DREDGING/BEACH FILL PLACEMENT

- CONTRACTOR QUALITY CONTROL). If the Contracting Officer determines the quality of beach fill is being adversely affected, that location shall be avoided in future passes of the dredge.

3.2.7 Magnetic Anomalies

A magnetometer survey was conducted at the borrow site with buffered returns shown on the drawings.

3.2.8 Probability of Rock in Borrow Area

It is not anticipated that material greater than 3/4" will be encountered at each borrow area. Dredging shall be restricted to the borrow area limits shown on the plans. The Contractor is put on notice that materials outside the borrow area contain a higher percentage or rock fragments within the sand and continuous rock surfaces.

3.2.9 Dredge Location Control

The Contractor shall have, in continuous operation on the dredge, electronic positioning equipment that will accurately and continuously compute and plot the position and the deepest penetration of the dredge.

3.2.9.1 Hopper and Scow Control

However, in the event of NDQMP System failure (not fully operational), the Contractor shall notify the Contracting Officer and continue tracking using the vessel electronic positioning equipment for up to 48 hours until the NDQMP System is fully operational and in use. If, upon NDQMP System failure, the Contractor cannot use vessel electronic positioning equipment or cannot use the NDQMP System within 48 hours of failure, all dredging operations for the vessel shall cease until the NDQMP System is fully operational. Any delays resulting from NDQMP System failure shall be at the Contractor's expense.

3.2.9.2 Other Dredge Type Control

Other dredge types shall meet all of the following requirements, and this information shall be compiled and submitted to the Contracting Officer bi-weekly:

a. The Contractor is required to have electronic positioning

GROUP4-10-R-0027 SECTION 35 20 25 Page 18 Revision 0005 equipment that shall horizontally locate the dredge when operating on the project, as well as determine the depth of dredging. Continuous locations of the dredge shall be made at all times during dredging.

b. A color-coded plot, in the project reference datum, of the draghead, cutterhead, or other hydraulic or mechanical dredging device shall also be recorded daily depicting the vertical and horizontal limits of the material dredged that day. Any horizontal or vertical dredge violations shall be clearly defined.

c. The Contractor is required to calibrate the equipment as required by the manufacturer or as required by the Contracting Officer. Proof of calibration shall be submitted to the Contracting Officer.

d. For Horizontal control, the location of the dredge is to be computed by coordinates with a probable range error not to exceed +/- 3 feet. The Contractor's method of horizontal location of the dredge shall be submitted for review. LORAN-C shall not be permitted for location control.

e. The Contractor is also required to have a depth of dredging indicator accurate to within one half a foot (0.5 feet). The instrument used shall indicate the depth of dredging at all times. This equipment shall include real-time measurement of the water (tide) level. The reported elevation of dredging shall be adjusted by the measured water level elevation and shall have a probable range error not to exceed 0.5-feet vertical.

f. If the dredge is outside the borrow area limits, the Contractor shall provide reason the dredge is outside the borrow area limits such as turning around annotated on the position chart and the dredge depth…
