The Contractor's entrances are shown on the drawings and are shared by others. The Contractor shall comply with all language contained within the Rights of Entries obtained by the United States Army Corps of Engineers (USACE). The Contractor is responsible for obtaining and complying with all Federal, State, County, and any other jurisdictional agency, requirements for permits, criteria, and use. The South Bay Boat Ramp existing access ramps as shown shall not be used for construction.

For construction access, construct access ramps and turn-around to accommodate construction equipment and construction means and methods.

While working in or driving through the limits of the South Bay Boat Ramp (Station 2637+00 to Station 2647+00), the Contractor shall use flagmen to direct and coordinate all traffic movement within the limits of the South Bay Boat Ramp.

For access and traffic control along the crest of HHD, the Contractor may elect to design and construct temporary turnouts every 1000 feet along the embankment. If so elected, the Contractor must provide a design and submit a Temporary Turnout Plan for approval by the government prior to commencement of work. The plan shall comply with the requirement of Haul Road prescribed in Specification Section 01 50 02 Temporary Construction Facilities.

The Contractor may utilize area within the limits of construction as laydown areas. The limits of construction are shown. If the lakeside slope of the embankment is used, the lakeside slope will be subject to lake-stage, lake-surge and lake-waves which may inundate the lakeside slope, see specification section 00 33 50 .

1.7 LAYOUT OF WORK

Read this paragraph in conjunction with the Clause LAYOUT OF WORK (FAR 52.236-17) of Section 00700 CONTRACT CLAUSES in Volume 1.

SECTION 01 11 00 Page 4 Amendment 0003

1.7.1 Established Project Control

The Government has established monuments along the work site(s). Each monument is represented in the contract drawings by a Designation and in most cases, an alphanumeric Permanent Identifier (PID). Information concerning the location and elevations can be found within the Survey Notes on the plan sheets. The Survey Notes for each included field survey will cite a particular survey number, and specify the control used to conduct that survey. Additional information is included in the Survey Notes that must be duplicated if an attempt to recreate the subject survey is desired.

See Section 00 31 21 CONTROL MONUMENT DESCRIPTIONS.

1.7.2 Layout

From the monuments, control data and elevations established by the Government, the Contractor shall complete the layout of the work and shall be responsible for all measurements that may be required for the execution of the work to the location and limit marks prescribed in the specifications or on the contract drawings, subject to such modifications as the Contracting Officer may require to meet changed conditions or as a result of necessary modifications to the contract work.

1.7.3 Survey

The Contractor shall furnish, at his own expense, such stakes, templates, platforms, equipment, tools and material, and all labor as may be required in laying out any part of the work from the monuments, control data and elevations established by the Government. It shall be the responsibility of the Contractor to maintain and preserve all stakes and other marks established by the Contracting Officer until authorized to remove them, and if such marks are destroyed by the Contractor or through his negligence, prior to their authorized removal, they may be replaced by the Contracting Officer, at his discretion, and the expense of replacement will be deducted from any amounts due or to become due the Contractor.

The Contracting Officer may require that work be suspended at any time when location and limit marks established by the Contractor are not reasonably adequate to permit checking of the work.

1.8 DAMAGE TO WORK

The responsibility for damage to any part of the permanent work shall be as set forth in Clause PERMITS AND RESPONSIBILITIES of Section 00700 CONTRACT CLAUSES in Volume 1. However, if, in the judgment of the Contracting Officer, any part of the permanent work performed by the Contractor is damaged by flood, earthquake, hurricane, or tornado, which damage is not due to the failure of the Contractor to take reasonable precautions or to exercise sound engineering and construction practices in the conduct of the work, the Contractor will make the repairs as ordered by the Contracting Officer and full compensation for such repairs will be made at the applicable contract unit or lump sum prices as fixed and established in the contract. If, in the opinion of the Contracting Officer, there are no contract unit or lump sum prices applicable to any part of such work, an equitable adjustment pursuant to Clause CHANGES of Section 00700 CONTRACT CLAUSES in Volume 1 will be made as full compensation for the repairs of that part of the permanent work for which there are no applicable contract unit or lump sum prices. Except as herein provided, damage to all work (including temporary construction), SECTION 01 11 00 Page 5 Amendment 0003 utilities, materials, equipment and plant shall be repaired to the satisfaction of the Contracting Officer at the Contractor's expense, regardless of the cause of such damage.

1.9 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 shall be in a condition equal to or better than that which existed before new work started.

1.10 EXISTING UTILITIES

1.10.1 Under Ground Utility Location

All underground utilities within the work limits must be positively identified in accordance with the American Society of Civil Engineers, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data (latest edition). All underground utilities within the work limits must be positively identified by a private utility locating service and coordinated with the Government. Any utilities found which are not shown on the construction drawings must be brought to the Contracting Officer's attention prior to proceeding with construction.

The Contractor shall coordinate service disconnections of active utilities with the Contracting Officer at least 30 days prior to impacting the utility with construction activities and shall provide weekly progress updates until such time that the utility is taken out of service. The progress update shall include the date at which the active utility impacts construction such that there is no disruption to the Contractor's work and progress.

1.10.2 Notification Prior to Excavation

Notify the Contracting Officer at least 15 days prior to starting excavation work. Contact utility authority 15 days prior to excavating.

Contractor is responsible for marking all utilities not marked by utility authority.

1.10.3 Utilities at South Bay Boat Ramp

At the South Bay Boat Ramp there is an inactive 12 inch ductile iron pipe, raw waterline, crossing the cutoff wall alignment. The Contractor shall remove this pipe and appurtenant features from the embankment to the limits shown. Abandon any portion of pipe not removed in accordance with Section 02 41 00 DEMOLITION. The excavation shall be backfilled with compacted soil in accordance specification section 35 41 00 EMBANKMENT

CONSTRUCTION.

1.10.4 Utilities at Structure S-276

At Structure S-276 there are underground utilities buried approximately 3

SECTION 01 11 00 Page 6 Amendment 0003 feet deep. The Contractor shall coordinate through the Contracting Officer with Operations Division staff to de-energize and secure the utilities. The Contractor shall remove the wires from each (6 are expected) conduit, remove a section from each conduit as required to install cutoff wall beneath the conduits. Once the cutoff wall is installed, install the section of removed conduit and install the wires as they were prior to construction.

1.10.5 Piezometers

Protect existing piezometers during construction. Should an existing piezometer become damaged, the Contractor shall provide piezometer(s) in accordance with Section 02 32 10 SUBSURFACE DRILLING AND SAMPLING FOR PIEZOMETER INSTALLATION at no cost to the Government. Existing piezometers shown shall be automated in accordance with Section 33 24 15

VIBRATING WIRE PIEZOMETERS.

1.11 TIME EXTENSIONS FOR UNUSUALLY SEVERE WEATHER (31 OCT 1989)

This provision specifies the procedure for the determination of time extensions for unusually severe weather in accordance with the Clause DEFAULT (FIXED-PRICE CONSTRUCTION) of Section 00700 CONTRACT CLAUSES in Volume 1. In order for the Contracting Officer to award a time extension under this clause, the following conditions must be satisfied:

a. The weather experienced at the project site during the contract period must be found to be unusually severe; that is, more severe than the adverse weather anticipated for the project location during any given month.

b. The unusually severe weather must actually cause a delay to the completion of the project. The delay must be beyond the control and without the fault or negligence of the Contractor.

1.11.1 Schedule of Monthly Anticipated Adverse Weather Delays

The schedule of monthly anticipated adverse weather delays is based upon National Oceanic and Atmospheric Administration (NOAA) or similar data for the project location for a daily precipitation greater than or equal to

0.50 inches and will constitute the base line for monthly weather time evaluations. The Contractor's progress schedule must reflect these anticipated adverse weather delays in all weather dependent activities.

See Section 00 33 50 WEATHER AND WATER STAGE DATA to obtain MONTHLY

ANTICIPATED ADVERSE WEATHER DELAY WORK DAYS BASED ON 5-DAY WORK WEEK.

1.11.2 Contractor Responsibility

Upon acknowledgment of the Notice to Proceed (NTP) and continuing throughout the contract, the Contractor will record on the daily CQC report the occurrence of adverse weather and resultant impact to normally scheduled work. Actual adverse weather delay days must prevent work on critical activities for 50 percent or more of the Contractor's scheduled work day. The number of actual adverse weather delay days shall include days impacted by actual adverse weather (even if adverse weather occurred in previous month), be calculated chronologically from the first to the last day of each month, and be recorded as full days. If the number of actual adverse weather delay days exceeds the number of days anticipated in Section 00 33 50 WEATHER AND WATER STAGE DATA (rounded to the nearest whole number), the Contracting Officer will convert any qualifying delays

SECTION 01 11 00 Page 7 Amendment 0003 to calendar days, giving full consideration for equivalent fair weather work days, and issue a modification in accordance with the Clause DEFAULT (FIXED PRICE CONSTRUCTION) of Section 00700 CONTRACT CLAUSES in Volume 1.
