1.12 PROFIT

a. Weighted guidelines method of determining profit shall be used on any equitable adjustment change order or modification issued under this contract. The profit factors shall be as follows:

Factor Rate Weight Value Degree of Risk 20 See Item Relative difficulty of work 15 b. below Size of Job 15 Period of performance 15 Contractor's investment 5 Assistance by Government 5 Subcontracting 25

b. Based on the circumstances of each procurement action, each of the above factors shall be weighted from .03 to .12 as indicated below. The value shall be obtained by multiplying the rate by the weight. The value column when totaled indicates the fair and reasonable profit percentage under the circumstances of the particular procurement.

(1) Degree of Risk. Where the work involves no risk or the degree of risk is very small, the weighting should be .03; as the degree of risk increases, the weighting should be increased up to a maximum of .12. Lump sum items will have, generally, a higher weighted value than the unit price items for which quantities are provided. Other things to consider: the portion of the work to be done by subcontractors, nature of work, where work is to be performed, reasonableness of negotiated costs, amount of labor included in costs, and whether the negotiation is before or after performance of work.

(2) Relative Difficulty of Work. If the work is most difficult and complex, the weighting should be .12 and should be proportionately reduced to .03 on the simplest of jobs. This factor is tied in to some extent with the degree of risk. Some things to consider: the nature of the work, by whom it is to be done, where, and what is the time schedule.

(3) Size of Job. All work not in excess of $100,000 shall be weighted at .12. Work estimated between $100,000 and $5,000,000 shall be proportionately weighted from .12 to .05.

(4) Periods of Performance. Jobs in excess of 24 months are to be weighted at .12. Jobs of lesser duration are to be proportionately weighted to a minimum of .03 for jobs not to exceed 30 days. No weight where additional time not required.

DOCUMENT 00 73 00 Page 5

(5) Contractor's Investment. To be weighted from .03 to .12 on the basis of below average, average, and above average. Things to consider: amount of subcontracting, mobilization payment item, Government furnished property, equipment and facilities, and expediting assistance.

(6) Assistance by Government. To be weighted from .12 to .03 on the basis of average to above average. Things to consider: use of Government-owned property, equipment and facilities, and expediting assistance.

(7) Subcontracting. To be weighted inversely proportional to the amount of subcontracting. Where 80 percent or more of the work is to be subcontracted, the weighting is to be .03 and such weighting proportionately increased to .12 where all the work is performed by the Contractor's own forces.

1.13 AS-BUILT DRAWINGS

The Contractor shall provide a marked-up half size drawing to show actual work performed to include necessary sketches, modification drawings, shop drawings and notes. Red ink is to be used for additions and deviations from the contract. Green ink is to be used to indicate work deleted from the contract. The drawings shall be maintained by the contractor as the work progresses and available for review by the government representatives. The as-built drawings shall be submitted for approval at the completion of the project. The completed set shall be available at time of final inspection.

1.14 PORTABLE TOILETS

Toilet facilities will not be available for Contractor's use. The Contractor shall provide and maintain portable toilets for use by the Contractor's staff and Government staff. Toilet(s) shall be placed at the location directed by the Contracting Officer. To prevent overturning by high winds, all portable toilets shall be anchored down.

1.1 APPLICABLE REGULATIONS AND PUBLICATIONS

All diving operations shall be performed in accordance with the following regulations and publications. Where there is a difference in standards that exist, the more stringent regulation or publication shall apply. Where the specifications are more stringent than the regulations and publications, the specifications shall apply.

1.1.1 US Army Corps of Engineers EM 385-1-1(30 NOV 2014) Safety and

Health Requirements Manual (Primarily Section 30) available on-line at http://www.usace.army.mil/Safety-and-Occupational-Health/Safety-and-Health- Requirements-Manual

1.1.2 OSHA 29 CFR 1910 Subpart T (OSHA

1.2 GENERAL REQUIREMENTS

The Contractor shall provide all necessary personnel and equipment to perform the work described herein, to place and remove temporary plug(s) as required to perform repair work on the lower level intake pipe at the Bear Creek Dam Intake Structure. Diving work will be accomplished using surface-supplied air (SSA).

1.2.1 DRAWINGS

See drawings for locations of intake structure and low level intake at bottom of reservoir. Larger and more detailed drawings may be available and at the U.S. Army Corps of Engineers, Tri-Lakes Office.

1.2.2 WORK AND DIVE CREW

The work will be accomplished using surface-supplied air (SSA) and a dive crew manned as prescribed in EM 385-1-1 (30 NOV 2014).

SECTION 01 08 00 Page 2

1.2.3 EQUIPMENT REQUIRED

The Contractor shall provide primary and emergency air supply, dive suits, hoses, lines, and all other related diving and safety equipment necessary for the work to be performed.

1.2.4 DIVER COMMUNICATIONS

(1) Hardwire communication with the divers is required at all times.

Electronic communication systems with an external speaker shall be incorporated so the entire dive team can monitor communications.

(2) Communications devices shall be tested prior to each dive, maintained in an operable condition, and protected from damage during use and storage IAW the manufacturer’s recommendations.

(3) All dive operations will be terminated in a safe, orderly fashion using line-pull signals if voice communications are lost.

After completing pipe repairs, a dive will be performed to release water into the tunnel by partially deflating the inflatable plug to introduce water to the pipe and check the butterfly valve, flexible couplings and seal for integrity. Secure the inflatable plug in the tunnel to prevent displacement during deflating.

This portion of the work will be repeated until the acceptable level of leakage has been attained as stated in the Statement of Work. After the leakage rate has been determined to be acceptable to the Government, a final dive will be performed to remove the inflatable device(s).

1.3.1 DEPTH OF DIVE

The depth of the water where the work is to be performed will be approximately a maximum of 31 feet to the lowest level of intake opening.

The projected pool elevation during the dive is expected to be 1558 feet

MSL.

1.3.2 LOCATION OF THE DIVE

The location of the work is at the northeast end of the reservoir, directly over and around the submerged low level intake opening of the 36 inch diameter pipe that feeds the lower butterfly valve located in the intake structure building.
