About this file

This document is Addendum #1 for the Bay Pines National Cemetery Gravesite Expansion Phase 2 project, dated 27 June 2025. The addendum details multiple revisions to contract drawings and specifications across 23 separate items, focusing on modifications to site plans, road profiles, erosion control plans, and technical specifications.

Key drawing revisions include shifting Road B 12' to the northwest, adjusting project limits of disturbance, adding new storm drainage profiles, modifying road radii and elevations, and updating erosion and sedimentation control plans. Specification changes involve updates to natural stone veneer engraving requirements, joint sealant specifications, and precast columbarium unit surface finishes. The addendum also introduces a new specification section for Temporary Environmental Controls (Section 01 57 19), which provides comprehensive guidelines for environmental protection, including management of air, water, land resources, noise control, and waste disposal during construction activities.

10.Handle discarded materials other than those included in the solid waste category as directed by the CO/COR.

C. Protection of Water Resources: Keep construction activities under surveillance, management, and control to avoid pollution of surface and ground waters and sewer systems. Implement management techniques to control water pollution by the listed construction activities that are included in this contract.

1. Washing and Curing Water: Do not allow wastewater directly derived from construction activities to enter water areas. Collect and place wastewater in sediment basins prior to entering retention/detention ponds, allowing the suspended material to settle, the pollutants to separate, or the water to evaporate.

2. Control movement of materials and equipment at stream crossings during construction to prevent violation of water pollution control standards of the Federal, State, or local government.

3. Monitor water areas, wetlands and wetland buffers affected by construction.

D. Protection of Fish and Wildlife Resources: Keep construction activities under surveillance, management, and control to minimize interference with, disturbance of, or damage to fish and wildlife.
