Total Project Site Excavation: 160.5934m3

13 December 2021Excavation Validation Package Project Title: EC17-05 VMF Unit: CTG 68.2 - NMCB ONE Prepared By: CTU 68.2.1 - Detail Ukraine

Summary:

The following is a breakdown of the total excavation required on the VMF to ensure that the Detail does not come across additional asbestos containing material for the duration of the project.

The overall site excavation volumes seen below show what remains to be excavated in teal. The voids in the left and rear portions show what has already been excavated by the detail. The volumes have been separat-ed into 23 parts and their volume calculations can be seen in the following pages.

For the Utility trenches, the project plans were blown up to a 1:1 scale using digital design programs to allow for a more accurate depiction of the overall lengths of each trench.

Finally, with the spoils likely being removed from the site, the project will require additional select �ll materi-al for back�ll and compaction. The total volume of back�ll was calculated by taking the total excavation and subtracking the trenches’ bedding sand volume

Trench Width and Depth Calculations:

Note: Trench Excavation calculations are based on the maximum trench size for a 4” underground pipe. Trench dimensions will vary slightly based on size of pipe but will have a di�erence of less than 100mm in depth and width.

- 4” pipe = 101.6mm

Depth:

- 101.6mm (pipe diameter) + 150mm bedding thickness + 800mm minimum coverage for frost protection = 1051.6mm or 1.0516m

Width:

- 101.6mm (pipe diameter) + Max 300mm each side = 701.6mm or .7016m

Overall Utility Trench Calculations:

Under Ground Communications: 143.4001 x 1.0516 x .7016 = 105.8m3

Under Ground Electrical: 399.8108 x 1.0516 x .7016 = 294.9814m3

Water: 396.1272 x 1.0516 x .7016 = 292.2636m3

Total Utility Trench Excavation Volume = 693.045m3

Total Excavation Volume of Project EC17-005:

Total Project Site Excavation + Total Utility Trench Excavation Volume = Total Excavation Volume

160.5934m3 + 693.045m3 = 853.6384m3

Select Fill Requirement:

Total Excavation Volume - Bedding Sand Volume = Total Select Fill

Bedding Sand Volume = 939.3381(linear meters of trenches) x .15 (depth of bedding sand) x .7016 (Width) = 98.8559m3

853.6384m3 - 98.8559m3 = 754.7825m3 Select Fill
