A.
All work performed as a consequence of these Rules and Regulations shall be subject to the review of the Board, which shall approve and accept or disapprove and reject each phase or portion of such work and at completion shall recommend the acceptance of all work or disapproval of the work with reasons therefor. The Board will employ a Registered Professional Engineer to act as its agent in the inspection of the work to insure compliance with these Rules and Regulations and to report to the Board his recommendations as to approval or disapproval of the work. Such Engineer will make certain inspections as prescribed herein in order to check the adequacy of the work at various stages prior to such work being covered by subsequent work. However, the Board, its Engineer, and such other persons as the Board may designate shall have the right to inspect the work any time. Therefore, the applicant shall at any time provide safe and convenient access to all parts of the work for inspection by the Board or its authorized agents.
B.
All work which has been disapproved or is not acceptable to the Board shall be removed and replaced or otherwise corrected to the point of complying with the requirements of the Board for acceptance. Any work which has been covered by subsequent work prior to acceptance, or is otherwise not available or obscured to the point of rendering inspection of the work difficult, shall be considered to be not acceptable to the Board. Such subsequent work shall be removed as directed by the Engineer to insure availability of the work to be inspected as required herein. The release of the performance guarantee shall depend upon the acceptance of all work prescribed herein and on the Definitive Plan and as directed by the Board.
C.
At points indicated in Article V and as further described hereinafter, the construction of the required improvements shall be inspected by the Board's Engineer or authorized agent, and unless approval of the work completed, including approval of materials used, to each such point has been given in writing, no further work shall be commenced. Such inspections may include the taking of certain samples for laboratory analysis or testing; in such cases, the applicant shall insure that the Engineer is in no way hindered or obstructed in the course of obtaining such samples. Where such samples are removed from the completed work, the applicant shall replace and restore such work, to the satisfaction of the Engineer, to its condition prior to the taking of the sample. The Engineer may require certified copies of delivery receipts or bills of lading or other certification as to the description of materials used or incorporated in the work. The Engineer may also require a sample of any materials or supplies which may be incorporated in the work; such samples shall be furnished at the expense of the applicant, and the applicant shall be liable for all costs and fees incurred by the Board as a result of testing such materials.
