SECTION 01 11 00

SUMMARY OF WORK

PART 1 GENERAL

1.1 SCOPE OF SECTION

This section presents a general description of the work to be accomplished under this contract on Brigantine Island, between Absecon Inlet and Brigantine Inlet located in Atlantic County, New Jersey, and the work to be accomplished under this contract at Great Egg Harbor Inlet and Peck Beach located in Ocean City, New Jersey.

1.2 DESCRIPTION OF WORK

1.2.1 Base Bid

The contract work consists of a Base Bid to place, along the Atlantic Ocean coastline, approximately 350,000 cubic yards of beachfill in the northern portion of Brigantine Island between 14th Street South and 1,000 feet north of 14th Street North, and approximately 1,000,000 cubic yards of beachfill between the groin at Seaview Road and 14th Street in Ocean City. With respect to Ocean City, present surveys currently indicate that beachill will only be placed in these areas. However, due to the dynamic nature of the shoreline, beachfill may be needed anywhere within the Federal project limits at the time of actual construction, namely from the groin at Seaview Road to 36th Street.

In addition to beachfill, the Base Bid work for both Brigantine Island and Ocean City will include providing and installing groin hazard signs.

In addition to beachfill, the Base Bid work for Brigantine Island includes: the re-construction of pedestrian crossovers; planting dune grass; structure monitoring; and providing sand and split rail fence.

1.2.2 Options

The contract work may also consist of three separate options (Options 1, 2 and 3) to place an additional 25,000, 50,000 and/or 75,000 cubic yards of beachfill on Brigantine Island, and three separate options (Options 4, 5 and 6) to place an additional 200,000 cubic yards of beachfill per option in the Ocean City project area, depending on which, if any, options are awarded. Pre-placement condition surveys, as specified in Section 01 71 23 SURVEY REQUIREMENTS, will determine the exact location and quantity of beachfill material required within the limits indicated, and will be a determining factor in the award of Options for additional quantities of beachfill. Where Options for additional beachfill are awarded, the additional beachfill material shall be placed immediately after the initial Base Bid quantity has been placed in the area(s) to be covered by the awarded Option. The intent is to complete the beachfill template in a given Base-plus-Option area, before proceeding with work further along the construction baseline for a particular project site.

In addition to beachfill, the contract work for Ocean City may include one or more options for stormwater outfall work (Options 7 through 13), consisting of replacing various lengths of 12-inch and 24-inch ductile iron pipe and replacement of damaged or missing pile bents, top and bottom pipe support timbers, and side timber bracing for 12-inch, 18-inch, and 24-inch

Section 01 11 00 Page 1 outfall pipes. If awarded, this work shall be coordinated with City of Ocean City officials.

1.2.3 Common Work

All beachfill work---Base Bid and Option, Brigantine and Ocean City---will include the requirements for structure monitoring as specified in the contract package.
