1.2.5 TIME EXTENSIONS FOR UNUSUALLY SEVERE WEATHER

1. This provision specifies the procedures for determination of time extensions for unusually severe weather in accordance with the contract clause entitled "Default: (Fixed Price Construction)". 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.

2. The following schedule of monthly anticipated adverse weather delays is based on National Oceanic and Atmospheric Administration (NOAA) or similar data for the project location 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.

MONTHLY ANTICIPATED ADVERSE WEATHER DELAY

WORK DAYS BASED ON (5) DAY WORK WEEK

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 paragraph 2, above, the contracting officer will convert any qualifying delays to calendar days, giving full consideration for equivalent fair weather work days, and issue a modification in accordance with the contract clause entitled "Default (Fixed Price Construction)".

SECTION 01 35 13 Page 1032

1.2.6 Contract Accruals

The Contractor shall submit a monthly listing of accruals. Accruals are used to provide projections of the incremental costs not yet paid for, but earned.

1.2.7 PROJECT/SITE CONDITIONS

1.2.7.1 Condition and Use of Project Site

The drawings indicate elevations and the reference drawings indicate the latest elevations at the project site. A notification of at least five (5) calendar days shall be given to the Contracting Officer prior to bringing any equipment or material to the work site. The Contractor shall be responsible for damages that may be suffered due to his operations. The Contractor shall note Clause entitled "Protection of Existing Vegetation, Structures, Equipment, Utilities and Improvements."

However, it is the responsibility of the Contractor to establish the exact horizontal and vertical location and size of all existing utility lines which are located within the required work area. The Contractor shall confer with the owners of the crossings regarding their exact locations and elevations and will be held responsible for any damages done to them by the construction operations. If the Contractor damages any existing utility line, vegetation, structure, equipment or improvement, a report thereof shall be made immediately to the Contracting Officer. In any event, existing utility lines, vegetation, structures, equipment or improvements shall be protected from damage, and if damaged, shall be repaired by the Contractor at his own expense.

If, in the opinion of the Contracting Officer, there are not contract unit or lump sum prices applicable to any part of such work an equitable adjustment pursuant to the Contact Clause entitled "Changes" of the contract, will be made as full compensation for the repairs of the part of the permanent work for which there are no applicable contract unit or lump sum prices.

SECTION 01 35 13 Page 1036

PART 3 EXECUTION

3.1 CONTRACTOR RESPONSIBILITIES

Transportation for Inspectors - The Contractor will be required to furnish, on the request of the Contracting Officer or any inspector, suitable transportation from all points on shore designated by the Contracting Officer to and from the various pieces of plant, and to and from the various parts of the work. Should the Contractor refuse, neglect, or delay compliance with these requirements, the specific facilities may be furnished and maintained by the Contracting Officer, and the cost thereof will be deducted from any amounts due or to become due the Contractor.

The Contractor acknowledges that it has taken steps reasonably necessary to ascertain the nature and location of the work, and that it has investigated and satisfied itself as to the general and local conditions which can affect the work or its cost, including but not limited to:

(1) conditions bearing upon transportation, disposal, handling, and storage of materials;

(2) the availability of labor, water, electric power, and roads;

(3) uncertainties of weather, river stages, tides, or similar physical conditions at the site;

(4) the character of equipment and facilities needed preliminary to and during work performance.

The Contractor also acknowledges that it has satisfied itself as to the character, quality, and quantity of surface and subsurface materials or obstacles to be encountered insofar as this information is reasonably ascertainable from an inspection of the site, as well as from the drawings and specifications made a part of this contract. Any failure of the Contractor to take the actions described and acknowledged in this paragraph will not relieve the Contractor from responsibility for estimating properly the difficulty and cost of successfully performing the work, or for proceeding to successfully perform the work without additional expense to the Government.

The Government assumes no responsibility for any conclusions or interpretations made by the Contractor based on the information made available by the Government. Nor does the Government assume responsibility for any understanding reached or representation made concerning conditions which can affect the work by any of its officers or agents before the execution of this contract, unless that understanding or representation is expressly stated in this contract.

3.2 LAYOUT OF WORK

The Government has established bench marks and horizontal control points at the site of the work. These are described and indicated on contract drawings.

From these control points the contractor shall lay out the work by establishing all lines and grades at the site necessary to control 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. The Contractor shall establish

SECTION 01 35 13 Page 1037 and maintain at the site of the work any horizontal and vertical controls shown on the contract drawings.

The Contractor shall furnish, at his own expense, all such stakes, spikes, steel pins, templates, platforms, equipment, tools and material and all labor as may be required in laying out any part of the work from the control points established by the Government. It shall be the responsibility of the contractor to maintain and preserve all stakes and other markers established by him until authorized to remove them. If any of the control points established at the site by the Government are destroyed by or through the negligence of the Contractor prior to their authorized removal, they may be replaced by the Contracting Officer, and the expense of replacement will be deducted from any amount due or which may become due the Contractor. The Contracting Officer may require that work be suspended at any time when horizontal and vertical control points established at the site by the Contractor are not reasonably adequate to permit checking the work. Such suspension will be withdrawn upon proper replacement of the control points.

3.3 Construction Procedure

The plan for repair of the East and West Arrowhead Breakeate is typical for a rubble mound stone structure. The order of the work is as follows:

A. Place and grade the bedding stone – Type “C” stone.

B. Place and grade the under layer stone – Type “B” stone on the bedding stone to the depth specified on the contract drawings. Note that the entire berm must be constructed prior to any construction above its top elevation to insure adequate slope stability.

C. The cover layer which is composed of Type “A” stone is to be constructed last by placing each unit individually in a random manner starting at the base of the slope and working toward the top. The cover layer shall be placed in a nominal two-layer thickness.

Construction practices for placement and quality of materials will follow those marine procedures normally found acceptable by the U.S. Army Corps of Engineers.
