About this file
This document is a sealed set of technical drawings and specifications for the City of Roswell Water Treatment Plant (WTP) project. The construction project involves site preparation, erosion control, grading, utility installation, and the construction of concrete infrastructure including sidewalks, stairs, and a retaining curb system at the WTP facility located at 70 Mansell Court, Suite 200, Roswell, Georgia 30076. The project encompasses approximately 1,200 square feet of disturbance area (0.03 acres) and includes two alternate bid items: concrete stairs with handrail and a six-inch thick concrete sidewalk. Key site features identified in the drawings include the operations control building, chemical storage and unloading areas, flocculation/sedimentation basins, clearwell, high service pump station, lime building, and various stormwater management features including bioretention areas and porous paver sections. The general contractor is responsible for site demolition, utility coordination, field verification of existing utility locations and depths, compaction testing, erosion and sediment control implementation, and final grading and sodding of disturbed areas.
The technical specifications require 100 percent compaction of Standard Proctor per ASTM D-698 with field testing coordination by the geotechnical engineer, concrete treatment with Aquron or approved equivalent on all exposed concrete surfaces, and adherence to National Electrical Code standards for grounding systems and electrical installations. The contractor must verify clearances around existing electrical equipment, confirm water line depth and location to ensure a minimum of 3.0 feet clearance from proposed pad bottoms, and maintain existing drainage patterns. All concrete sidewalks must be four inches thick and broom finished with expansion joints at 60-foot intervals, and all disturbed areas must be sodded or hydroseeded. The document specifies that proposed and existing utility locations are schematic only and exact locations shall be determined during coordination with utility companies and field verification at groundbreak.
