Cyclic Maintenance on Gravel Roads and Storage Areas SOW

SOUTHEAST REGION

Introduction:

Vicksburg National Military Park (VICK) is comprised of several discontinuous units related to the US Civil War, including:

· The Campaign for Vicksburg: For 18 months Union and Confederate Forces engaged each other all through the region as they positioned for control of Vicksburg.

· The Siege of Vicksburg: For 47 days, the Union General US Grant held the Confederate Army and city of Vicksburg under a hard and brutal siege.

The multiple sites are managed under one administration and are located in and around a 40-mile radius surrounding Vicksburg, Mississippi. Sites related to the Campaign for Vicksburg include the Port Gibson Unit (Shaifer House), Raymond Unit (Battle of Raymond), and Champion Hill (Crossroads and Coker House). The Siege of Vicksburg sites include the main battlefield and National Cemetery within the City of Vicksburg, Pemberton's Headquarters, Louisiana Circle, Navy Circle, and the USS Cairo.

At the main battlefield unit at 3201 Clay Street, the park facilities maintenance complex is sited at a bottom of a hill along a drainage. The complex contains several buildings and gravel access roads.

Objective:

Vicksburg National Military Park plans to resurface existing gravel roads and parking/storage areas in and around the Maintenance Complex. A total of one (1) roads and two (2) parking/storage areas will be re-graveled as part of this project. These include the Maintenance Access Road (approximately 24,200 sf), Operations Building parking/storage (approximately 8,000 sf), and Upper Storage parking/storage (2,000 sf). Contractor will measure and verify the approximately 34,200 square feet of gravel roads and parking/storage areas to be resurfaced. See Figure 1 for map of areas.

· Resurfacing will include:

· Scarify road/parking lot surface to remove all grass and vegetation

· Regravel with “DOT base” of crushed limestone base rock, grade with crown for drainage. See Scope for depth of gravel to be used for each road/parking lot.

· Compact all gravel road/parking lot surfaces to approved psi (pounds per square inch).

· All new lime base and gravel will match the existing color of existing gravel drives and parking/storage areas.

· Gravel must meet Federal DOT standards for “DOT base” material and not be more than 1.5 inches in diameter.
