MS-2 median is shown on the plan incidental items quantity sheet as measured by the square yard, with a quantity of 10,537sy. A check of the quantity confirms measurement by the square yard. The bid item #1310 is measured by the linear foot, which is the correct unit of measure, however the quantity provided is the square yard quantity of 10,517. This quantity appears to be incorrect, Can you verify this and make the correction or detail how this item should be priced?

Borings 14BH-20, 14BH-21, 14BH-22, 14-BH23 only go to a depth of 25'. This is not nearly deep enough to determine the length of temporary sheet pile required for this area. Additional geotechnical information is required from VDOT in order for the contractor to make reasonable assumptions for design of the sheet pile wall. Based on current information a temporary sheet pile wall will not suffice for construction of the permanent sheet pile wall, or to hold up the existing roadway. Please provide additional boring information.

I already checked those and they are not deep enough either, and follow the alignment of the permanent sheet pile wall rather than the temporary sheet pile wall. Furthermore those indicate very poor soil conditions as evidenced by weight of hammer in the blow counts. The entire area is essentially slop. Deep Boeing’s are required to formulate a temporary sheet pile wall design.

The referenced borings were terminated at elevations ranging between El. -42 and El. -65 feet. Deeper borings were completed for the bridge foundations to the east. The deepest recommended tip elevation for the permanent sheet pile wall is El. -30 feet, which is above the bottom elevation of the test borings. The referenced borings indicate a layer of medium dense to dense sandy soils between approximate elevations El. -25 and -40 feet, with some variation. VDOT and its consultant designer are responsible for design of permanent features. Design of temporary support of excavation is the responsibility of the contractor.
