SUMMARY OF WORK

PART 1 GENERAL

1.1 SCOPE

This section presents a general description of the work to be accomplished under this contract at Indian River Inlet (IRI), in Delaware.

1.2 DESCRIPTION OF WORK

The contract work consists of placement of satisfactory beachfill material on Indian River Inlet North Shore to construct a beach berm and dune system along the Delaware coast, on the north side of Indian River Inlet, for coastal protection of Route 1.

a. Contract includes a Base Bid and 4 Options

b. The Base bid work includes the placement of approximately 300,000 cubic yards of satisfactory beachfill material along IRI north shore.

c. Option 1 includes the placement of 100,000 cubic yards of satisfactory beachfill material along IRI north shore.

d. Options 2, 3 and 4 each include the placement of 50,000 cubic yards of sand along IRI north shore shore.

e. The approved borrow area available for use under this contract is the Indian River Inlet Ebb Shoal, consisting of Area A and Area B.

Obtain all beachfill material for the work under this contract solely from this approved inlet borrow area. Beachfill material from any other source including trucking from upland sources will not be considered under this contract.

f. The use of mechanical/bucket dredges will not be allowed under this contract.

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 award of options for additional quantities of beachfill. Where options for additional beachfill are awarded, the additional beachfill will be placed immediately after the initial quantity.

1.3 CONTRACTOR ACCESS

Access to the work site is available by land and water. Access to the shorefront shall be at the locations indicated on the drawings. Access to the inlet borrow area is by water only. Conduct all investigations necessary to establish the specific routes to be used for the contract work. Compliance with all applicable Federal, State, County, and local regulations regarding weight limitations and other vehicle restrictions regarding the use of these routes is solely the responsibility of the Contractor.

Document the original conditions of the access area and route by taking detailed photographs of those areas prior to starting work. See Section

01 32 33 CONSTRUCTION PHOTOGRAPHY for requirements.

Any damage to the roads due to truck traffic or other Contractor operations shall be repaired, subject to the Contracting Officer's approval, at no additional cost to the Government.

1.4 CONTRACTOR'S WORK LIMIT

Significant differences between segments shall be defined as elevation differences greater than 1 foot over a distance of 10 feet or greater along a profile line, and occurring on two or more adjacent profile lines.

3.3 SURVEY CONTROL

a. Survey control descriptions are provided in Appendix A30 and https://rsgisias.crrel.usace.army.mil/apexcrrel/f?p=493:4. Survey the control network utilizing surveying procedures and methodology that meet or exceed accuracy tolerances of +/- 0.10 feet in the vertical and +/- 0.10 feet in the horizontal.

b. USACE-NAP survey control networks are periodically adjusted and updated. This process results in changes to control monuments and coordinates. It does not change the coordinates of the survey baseline.

The survey baseline coordinates and the coordinates of the physical monument may vary. It should be assumed that the survey control network and the survey baseline are independent entities. The physical monument may or may not be on the survey baseline. Establish the relationship between the supplied physical monumentation and the survey baseline.

c. If the name of the survey control point includes stationing or numbers of any kind, the station name should not be assumed to be exact stationing on the survey baselines or profile lines. Coordinates shown on the Survey Control Sheets (DA Form 1959) will govern. Station naming often refers to historic project information and standard calculations must be performed based on coordinates in order to derive the specific relationship between

SECTION 01 71 23 Page 5 the control point and the survey baseline.

d. Stake and flag all temporary bench marks or control points set within the work limits and clearly label the elevation of the point on the stake.

3.4 SURVEY LOGS

Prepare survey logs in digital spreadsheet form describing all survey progress and activity for pre- and post-placement condition surveys and for before- and after-dredging surveys and submit daily, by email, to the Philadelphia District Survey Point of Contact and the COR. The spreadsheet shall be an ongoing log describing all survey lines that have been started as well as completed.

b. BMAP Free Format

Format Description:

One ASCII file containing all data points for all cross sections.

For each cross section in the file, the format includes:

1. One profile header line including three fields separated by a space:

(a) Profile ID;

(b) Survey descriptor: "Preplacement"; "BD"; "AD"; or "Postplacement";

(c) Date of data collection in "YYYYMMDD" format

Note: Use Profile IDs listed in drawings for pre/post placement surveys;

Use station in "xxx+xx" format as Profile ID for BD/AD profile surveys

2. One line listing the integer number of points "N" in the profile

3. "N" lines including two fields separated by a space:

(a) distance from baseline (positive offshore, in ft);

(b) elevation (relative to NAVD 88, ft)

Notes:

a. Points within a cross-section should be sorted such that distances from baseline are listed in ascending order

b. No two points within a cross-section may have the same distance from baseline (adjacent points should be separated by distance of at least 0.1 ft)

c. The file should include no blank lines between data lines within a cross-section or between sequential cross-sections

Format Notation:

The format for each cross-section is represented notationally as:

"Profile Header" : Line 1 -- text line including profile ID; survey descriptor; survey date

"N" : Line 2 -- integer number of points in the cross section

"Xi" "Zi" : Lines 3 to N+2 -- X,Z data pair (distance offshore from baseline, elevation) separated by a space (listed in "i" rows from 1 to N)
