SUMMARY OF WORK

08/ 15, CHG 2: 08/ 21

PART 1 GENERAL

1.1 WORK COVERED BY CONTRACT DOCUMENTS

1.1.1 Project Description

The work includes construction of breakwaters and sills for Phase I of the Barren Island Restoration (BIR) project. The sills will be constructed from Sta 125+00 to 138+25, Sta 200+00 to 255+69, Sta 300+00 to 326+00, and Sta 400 to 410+17, and the breakwaters will be constructed from Sta 500+00 to 514+06, Sta 600+00 to 615+00, and Sta 700+00 to 713+64 as indicated on the drawings.

1.1.2 Location

The work is located at Barren Island is a U.S. Fish and Wildlife Service (USFWS) refuge located approximately 1 mile west of Upper Hoopers Island.

It is a small island located in the Chesapeake Bay off the coast of Dorchester County. Originally attached to the Delmarva Peninsula, Barren Island has now eroded into two smaller, separate land masses.

1.1.3 Transportation Facilities

The work site is accessible by water only. The Contractor must make their own investigation of transportation facilities in the vicinity of the work.

1.1.4 Weather Conditions

Complete weather records and reports may be obtained from the U.S. Weather Bureau. The Contractor must identify on their own the hazards likely to arise from weather conditions during the construction period. The site of work is exposed, and suspension of work may at times be necessary during storm periods. Anticipate the possible infrequent approach of tropical and subtropical storm systems, including hurricanes between Jun 01 and Dec

01. Anticipate possible ice conditions at the work site from December through March. Determine the effect that currents and wave action will have on construction operations. The mean range of tide (Mean High Water

- Mean Low Water) and the Great Diurnal Range of tide (Mean Higher High Water - Mean Lower Low Water) at Barron Island are 1.1 feet and 1.5 feet, respectively.

1.1.5 Subsurface Conditions

A subsurface exploration program has been conducted that consists of Cone Penetration Testing (CPT), Dilatometer Testing (DMT), and Standard Penetration Borings (SPT). CPT, DMT, and SPT logs are attached at the end of this specification. USACE will not provide any interpretation of the geotechnical testing. The locations of the tests are shown on the plans and reported on the boring logs. Samples taken during the SPT testing are avaialable for examination upon request. Prior to bidding, the samples are avaiable for examination at the USACE Soils Laboratory at Fort McHenry, MD. Notify the Contracting Officer listed in the solicitation to schedule a time to examine the samples.

SECTION 01 11 00 Page 1

1.2 EXISTING WORK

In addition to FAR 52.236-9 Protection of Existing Vegetation, Structures, Equipment, Utilities, and Improvements:

a. Remove or alter existing work in such a manner as to prevent injury or damage to any portions of the existing work which remain.

b. Repair or replace portions of existing work which have been altered during construction operations to match existing or adjoining work, as approved by the Contracting Officer. At the completion of operations, existing work must be in a condition equal to or better than that which existed before new work started.
