E.Basis of Acceptance. Scuppers, drainage troughs and downspouts shall be accepted at the work site by the Engineer -in-Charge upon certification of the manufacturer that the materials used and fabrication procedure employed conform to the requirements of section 576. The Eng ineer may reject any scupper, drainage trough or downspout system which, in his opinion, exhibits poor quality or workmanship.
576-3.02 Erection of Downspout Systems
A.General
1.Pipe Installation. The pipe shall be laid true to line and grade as shown on the plans or as directed by the Engineer, with joints close and even, so that a true and even surface of invert will be made over the joints throughout its entire length. Horizontal pipe shall be installed so that the minimum slope shall not be less than 1:50. Pipe shall be placed in accordance with the requirements of this specification unless special methods are called for on the plans or in the itemized proposal.
2.Field Testing. Prior to the acceptance of the structure by the Department, the downspout system should be flushed out and tested to insure that it is flowing at full capacity. Any obstruction in the downspout system preventing the free flow of drainage or its operatio n at full capacity shall be removed to the complete satisfaction of the Engineer.
