TASK 7 Equipment Rental <br />a) Additional Bulldozer Work <br />The existing drainage pattern, on and adjacent to the project area, is <br />shown on the drainage map included in this bid document (See Drainage <br />Plan). Also depicted on this diagram are Droposed drainage <br />improvements. POND A (existing) receives run-off from the northwestern <br />portion of the property and will remain in place. In this phase of the <br />project, the CONTRACTOR will reclaim any disturbance caused to this <br />drainage during the course of the project to restore the integrity of <br />this drainage and existing sediment pond. <br />An existing drainage which enters the project area from the west and <br />crosses through the central portion of the site, generally follows the <br />historical channel. The PIT 1 & PIT 2 complex excavation has since <br />captured some of the run-off from this channel. The CONTRACTOR will also <br />perform what surface work is required to restore all storm run-off to <br />this historic channel in such a fashion as to insure that Pond 8 is <br />utilized in sediment control. This will require the CONTRACTOR to <br />establish a drainage Swale from just west of the reclaimed strip-pits, <br />running northeast into Pond B (See Drainage Plan). This drainage Swale <br />has an estimated length of 500 feet. The dimensions of the drainage <br />Swale shall be 12 feet wide and one foot (1 ') deep with side slopes set <br />at 4:1 (h orizontal:vertical ). The Project Manager will provide reference <br />stakes to delineate the channel location. Any cut material proaiced from <br />establishing the drainage Swale shall be used as topsoil material and <br />will be placed according to the instructions of the PROJECT MANAGER. <br />Any additional bulldozer work which may arise will also be covered under <br />this task. <br />Specifications 15.0 of the "Standard Work Specification included in the <br />CMLRD General Bid Specifications, 1989 applies to this bid item. <br />b) Measurement and Payment <br />Payment for tJiis task will be reflectea under Item 7 of the Bid Scheti~le <br />as an hourly rate for a CAT D-6 bulldozer or equivalent machine.
