Specifications include, but are not limited to: On-going temporary use of bulldozer and other heavy equipment and operator services for the City of Savannah. Work will be on an "on call" basis as necessary when City equipment is inoperative. Response time is of particular importance. The City requires response within 24 hours of call to contractor. Additionally, on an as-needed basis, weekend work may be required of the contractor. Following are descriptions of the type of equipment needed. Bidders do not have to have all equipment to bid. All vehicles must have current DOT inspections and be able to operate safely on the highway. 4.6.1 Tandem Dump Truck (minimum of three (3) available, size - minimum 14 CY). 4.6.2 Loader (minimum of one (1) equal to, or better than, a Cat 930). Note: The working environment for this machine is particularly adverse to pneumatic tires. A loader with foam-filled tires, solid tires, or on tracks is therefore highly desirable. 4.6.3 Dozer (minimum of one (1) equal to, or better than a D-6). 4.6.4 Excavator (minimum of one (1) equal to, or better than a Deere 200). 4.6.5 Motor Grader (size – minimum twelve (12) feet).
