Each shipment of drawings shall be accompanied by a Transmittal Form furnished by the Contractor giving a list of the drawing numbers and the names mentioned above.

Only drawings, which have been checked and corrected by the fabricator, should be submitted to the Contractor by his subcontractors and vendors. Prior to submitting drawings to the Engineer, the Contractor shall check thoroughly all such drawings to be satisfied that the subject matter thereof conforms to the Drawings and Specifications in all respects. All drawings that are correct shall be marked with the date, checker's name, and indication of the Contractor's approval, and then shall be submitted to the Engineer; other drawings shall be returned for correction.

If a shop drawing shows any deviation from the Contract requirements, the Contractor shall make specific mention of the deviations in the Transmittal Form furnished by the Contractor and provide a description of the deviations in a letter attached to the submittal.

The review of shop and working drawings hereunder will be general only, and nothing contained in this GENERAL SPECIFICATION shall relieve, diminish or alter in any respect the responsibilities of the Contractor under the Contract Documents and, in particular, the specific responsibility of the Contractor for details of design and dimensions necessary for proper fitting and construction of the work as required by the Contract and for achieving the result and performance specified there under.

The marked-up reproducible of the shop and working drawings or one marked-up copy or catalog cuts will be returned to the Contractor. The Contractor shall furnish additional copies of such drawings or catalog cuts when so required.

6. Occupying Private Land. The Contractor shall not (except after written consent from the proper parties) enter or occupy with men, tools, materials, or equipment, the land outside the rights-of-way or property of the Owner. A copy of the written consent shall be given to the Engineer.

7. Interference With and Protection of Streets. The Contractor shall not close or obstruct any portion of a street, road, or private way without obtaining permits therefore from the proper authorities. If any street, road or private way shall be rendered unsafe by the contractor's operations, he shall make such repairs or provide such temporary ways or guards as shall be acceptable to the proper authorities.

Streets, roads, private ways, and walkways not closed shall be maintained passable and safe by the contractor, who shall assume and have full responsibility for the adequacy and safety of provisions made therefore.

The Contractor shall, at least 24 hours in advance, notify the Police (Traffic Safety) and Fire Departments in writing, with a copy to the Engineer, if the closure of a street or road is necessary. He shall cooperate with the Police Department in the establishment of alternate routes and shall provide adequate detour signs, plainly marked and well lighted in order to minimize confusion. The traffic signs shall conform to the Traffic Control Specifications hereafter described.

8. Storage of Materials and Equipment. All excavated materials and equipment to be incorporated in the work shall be stored so as not to injure any part of the Work or existing facilities and to ensure free access at all times to all parts of the Work and to all public utility installations in the vicinity of the Work.

The Contractor shall comply with all applicable Federal, State and local laws, ordinances, rules and regulations and lawful orders of all authorities having jurisdiction over the safety of persons and protection of property.

The contractor shall designate a responsible member of his organization at the site whose duty shall be the prevention of accidents. This responsible person shall have the authority to take immediate action to correct unsafe precautions and programs.

10. Sanitary Regulations. The Contractor shall provide adequate sanitary facilities for the use of those employed on the Work. Such facilities shall be made available when the first employees arrive on the site of the Work, shall be properly secluded from public observation, and shall be constructed and maintained during the progress of the Work in suitable numbers and at such locations and in such a manner as may be required. The Contractor shall maintain the sanitary facilities in a satisfactory and sanitary condition at all times and shall enforce their use. He shall rigorously prohibit the committing of nuisances on the site of the Work, on the lands of the Owner, or on adjacent property.

11. Lines, Grades and Measurements. The Contractor shall employ a competent civil engineer, registered within the Virgin Islands as a Professional Engineer or Land Surveyor. The Contractor shall require said engineer to establish all lines, elevations, reference marks, batter boards, etc., needed by the Contractor during the progress of the Work, and from time to time to verify such marks by instrument or other appropriate means.

The Engineer shall be permitted at all times to check the lines, elevations, reference marks, batter boards, etc., set by the Contractor, who shall correct any errors in lines, elevations, reference marks, batter boards, etc., disclosed by such check. Such a check shall not be construed to be an approval of the Contractor's work and shall not relieve or diminish in any way the responsibility of the Contractor for the accurate and satisfactory construction and completion of the entire Work.

The Contractor shall make, check, and be responsible for all measurements and dimensions necessary for the fittings in the Work.

12. Dimensions of Existing Structures. Where the dimensions and locations of existing structures are of importance in the installation or connection of any part of the Work, the Contractor shall verify such dimensions and locations in the field before the fabrication of any material or equipment which is dependent on the correctness of such information.

13. Work to Conform. During its progress and on its completion, the Work shall conform truly to the lines, levels, and grades indicated on the Drawings or given by the Engineer and shall be built in a thoroughly substantial and workmanlike manner, in strict accordance with the Drawings, Specifications, and other Contract Documents and the directions given from time to time by the Engineer.

14. Pipe Location. Exterior pipelines will be located substantially as indicated on the Drawings, but the right is reserved to the Owner, acting through the Engineer, to make such modifications in location as may be found desirable to avoid interference with existing structures or for other reasons. where fittings, etc., are noted on the Drawings, such notation is for the Contractor's convenience and does not relieve him from laying and jointing different or additional items where required. Small interior piping is indicated diagrammatically on the Drawings, and the exact location is to be determined in the field. Piping shall be arranged in a neat, compact, and workmanlike manner, with a minimum of crossing and interlacing, so as not to interfere with equipment or access ways, and, in general, without diagonal runs.

15. Limits of Normal Excavation. For pipes in trench, the normal width of the trench shall be measured between vertical planes which are a distance apart equal to the sum of 2 feet plus the outside diameter of the pipe. The normal depth shall be measured to a distance of 0.5 ft. below the bottom of the pipe.

For concrete placed directly against undisturbed earth, the normal width and depth of the excavation of such concrete shall be measured to the neat lines of the concrete as indicated on the Drawings or as ordered.

For concrete placed against rock surfaces resulting from rock excavation, the normal width and depth of the excavation shall be measured to 4 inch outside the neat lines of the concrete as indicated on the Drawings or as ordered.

For other structures, except manholes as noted below, the normal width shall be measured between vertical planes 1 ft. outside the neat lines of the several parts of the structure, except that the width at any elevation shall be measured as not less than the width at a lower elevation. The normal depth shall be measured to the underside of that part of the structure for which the excavation is made.

No additional width or depth of trench excavation in earth or rock shall be allowed at standard circular manholes.

Wherever bell holes are required for jointing pipe, they shall be provided without additional compensation over and above the resulting from measurements as above described.

16. Computation of Quantities. For estimating quantities in which the computation of areas by geometric methods would be comparatively laborious, it is agreed that the plain-meter shall be considered an instrument of precision adapted to the measurement of such areas.

It is further agreed that the computation of the volume of prismoids shall be by the method of average end areas.

17. Planning and Progress Schedules. Before starting the Work and from time to time during its progress, as the Engineer may request, the Contractor shall submit to the Engineer a written description of the methods he plans to use in doing the Work and the various steps he intends to take.

Within 15 days after the date of formal execution of AGREEMENT, the Contractor shall prepare and submit to the Engineer (a) a written schedule fixing the dates on which additional drawings, if any, will be needed by the Contractor and (b) a written schedule fixing the respective dates for the start and completion of various parts of the Work. Each such schedule shall be subject to review from time to time during the progress of the Work.

18. Precautions During Adverse Weather. During adverse weather and against the possibility thereof, the Contractor shall take all necessary precautions so that the Work may be properly done and satisfactory in all respects. When required, protection shall be provided by use of tarpaulins, wood and building-paper shelters, or other suitable means.

19. Electrical Energy. The Contractor shall make all necessary applications and arrangements and pay all fees and charges for electrical energy for power and light necessary for the proper completion of the work and during its entire progress. The Contractor shall provide and pay for all temporary wiring, switches, connections, and meters.

The Contractor shall provide sufficient electric lighting so that all work may be done in a workmanlike manner when there is not sufficient daylight.

20. Protection Against Electrolysis. Where dissimilar metals are used in conjunction with each other, suitable insulation shall be provided between adjoining surfaces so as to eliminate direct contact and any resultant electrolysis. The Insulation shall be bituminous impregnated felt, heavy bituminous coatings, nonmetallic separators or washers, or other acceptable materials.

21. Record Contract Drawings. Contractor shall keep one (1) record copy of all Contract Documents, reference documents, and all technical submittals at the Site in good order and annotated to show all changes made during the construction process. Record drawings shall be up-dated and kept current on a daily basis by the Contractor. The record drawings will be reviewed by the Engineer prior to approval of the Contractor's pay requests. At the completion of the Project and before final payment is made, Contractor shall furnish the Engineer with two

(2) set of clean, legible and clear documents , reflecting all changes herein described. Changes to the drawings shall be drafted in a neat and workmanlike manner. Contractor shall also submit the record drawings on a CD-R disk based on the design plans furnished by VIWAPA in electronic format (Auto Cad). Accurate and approved as built drawings will be submitted prior to final payment (retainage) on the contract.

Features on the new installed system shall be shown as follows:

A. For fittings and change in pipe direction (both horizontal and vertical) show station location and off set distance (right or left) and depth from top of pavement. All existing utilities encountered must be shown with depth, station location and detail of the crossing.

B. For valves, corporation stops, curb stops, stub-outs end caps and acoustic access points, show a minimum of three horizontal distances ties from permanent objects and depth from top of pavement. Permanent features include corners of concrete walls, building foundation corners, manhole covers and similar features. Where only semi-permanents features are available then four distance ties shall be used, such features include utility poles, trees, fence corners and similar features.

The information may be shown in a tabular format on each sheet provided the distance reference points are clearly identified and referenced.

22. District Meter and St. John Terminal Leak Repair. Install district meter vault, related piping and meter as shown on drawings. The location is on the section of pipe line installed previously, Phase 1B, where 12 inch stub outs have been furnished for this purpose. The finished installation shall be protected by bollards as shown. The meter assembly, 8 inch Sensus Fireline, will be furnished by VI WAPA to be installed by the contractor. The installation shall be tested for leakage.

The existing submarine pipe line land terminal connection has a known leak. The terminal is located in close proximity of the WAPA water production plant in Estate Enighed, St. John.

The connection needs to be excavated to expose the fittings. The leaking joint (the transition fitting from the submarine pipe to the standard ductile iron pipe) must be disassembled; the cause of the lead determined, new gaskets furnished and reassembled utilizing a transition fitting furnished by VI WAPA. The assembly shall be pressure tested to 150 psi for two hours. The lack of visible leakage at that assembly shall be considered satisfactory completion of the work. In the even the pressure does not hold or the allowable leakage is in excess of the allowable, then further work will be based on time and materials expended, but only after written authorization of the WAPA Engineer. The work area is to be backfilled.

Included in the St. John leak repair is the replacement of the sun shield, a lengthwise cut PVC pipe, over the submarine water pipe in the surf zone. Two shield sections have been torn loose. These are to be placed over the submarine pipe and strapped with five bands of stainless steel strapping spaced equally over the pipeline. The shields are at the site or will be furnished by VI WAPA at their St. Thomas plant.

23. Work At Electric Pad. The electric pad work is a modification of the existing high voltage electric above ground terminal connection for one of two St. John 34.5 KV submarine transmission lines. Prior to any work on this facility, the contractor must advise WAPA’s Manager of Construction in writing a minimum of 7 days, of the intent to perform the work.

WAPA will disconnect the power from the facility and disconnect the terminal connections. The contractor will be given written confirmation that the power is disconnected and that work can then proceed.

Once the work has started it must be completed without interruption, as the power supply to the island of St. John during that time is dependent on the other single remaining undersea cable.

Consequently the risk exists should a problem develop on the one operational cable; WAPA will be unable to furnish power to St. John. Hence it is imperative that work at the Red Hook site be completed without interruption and in the shortest possible time.

The existing terminal enclosure and below ground sleeve are to be removed and reused for the reconstructed pad. Care shall be exercised during the removal to avoid damage. Caution is also to used while working around existing components, including the riser pole, manhole, underground ducts and water system facilities. Should damage take place, WAPA will charge the contractor for damage; require repair or replacement of any damaged component. The two existing conduits are to be incorporated with the new conduits. The contract plans show a generalized detail; the actual conduit arrangement may vary, provided all conduits terminate in the enclosure. Backfill is to be compacted to 95% maximum density. Construct new concrete pad and remount the enclosure. WAPA will reenergize the system.
