TASK 7 Equi pment 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 proposed 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 B 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 (horizontal:vertical ). The Project Manager will provide reference <br /> stakes to delineate the channel location . Any cut material procuced 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 /> Speci fi cations 15 .0 of the "Standard Work Speci fi cation incl uaed in the <br /> CMLRD General Bid Specifications, 1989 applies to this bid item. <br /> b) Measurement and Payment <br /> Payment for this task will be reflected under Item 7 of the Bid Schedule <br /> as an hourly rate for a CAT D-6 bulldozer or equivalent machine. The <br /> hourly rate bid shall reflect the CONTRACTORS estimate for equi pnent and <br /> personnel costs per hour to complete the task.
