UNIT PRICE SCHEDULE NOTES AND DRAWINGS:

The following notes and drawing explain and define the line items of the Price Schedule. The notes are numbered to refer to the appropriate line item. These notes are drawings from a part of the Price Schedule and Contract Specifications.

GENERAL NOTES

· See “Area Conversion Chart” which is attached for Work Item 46. It may be used to convert outer diameter of pipe insulation to surface area of insulation in square feet per linear foot.

The Conversion Chart may also be used to determine the surface area of “bared” piping to determine WI 43 costs.

· The unit costs for all work items which either remove ACM or which remove ACM contaminated non-ACM have already included the costs of packaging, transporting and proper disposal of the resulting Asbestos Waste at “approved landfills”.

· The unit costs for all work items which provide materials (e.g. scaffolding, plywood, wafer boards, planks, etc.) have already included the costs of transporting them to the project site, and to the work area, and back out of the work area, etc., and cutting costs, if required.

· For fittings (elbow, tees, valves, etc.) add 3 L.F.

1. Area = (D x 3 ft. where D = outer diameter in feet

2. Asbestos Contractor shall use this formula to calculate area to be used for each fitting.

· For each flange add 4 LF . Area = (D x 4 LF where D = outer diameter in feet

a. Asbestos Contractor shall use this formula to calculate area to be used for each flange.

UNIT NOTES

Units listed in the Unit Price Schedule are defined below:

Note: See unit price schedule notes and drawings on the sheets which follow.

AREA CONVERSION CHART

This chart is provided for use in conjunction with the Price Schedule to convert pipe diameters and lengths to square foot surface units.

Example: To install new lagging on 12 linear feet of 5” outside diameter insulated pipe.

12 linear feet x 1.31 (factor for 5 inch diameter pipe) = 15.72 feet, round off to 16 square feet.
