About this file
This is a construction baseline and technical specification document for the Maple Avenue Reconstruction project in Connecticut, detailing the roadway improvements from Route 163 to the Department of Public Works (DPW) Garage. The project encompasses approximately 58.7 stations of roadway rehabilitation work, including 2-inch mill and overlay operations from station 0+30 to 32+50, full-depth reclamation from station 32+50 to 58+70, and various pavement widening and reconstruction activities. Key work items include the replacement of 444 feet of Type R-B 350 metal beam guiderail with end anchorages, installation of 506 linear feet of compost/woodchip erosion and sediment control sock in the initial phase and 280 linear feet in subsequent phases, replacement and adjustment of multiple catch basin tops with Connecticut Department of Transportation standard types (C, C-L, and C-M), installation of 23 linear feet of new 15-inch HDPE drainage pipe in one location and 275 linear feet in another location, construction of 4-foot bituminous concrete sidewalk sections, installation of various concrete curb walls and ramps, and application of epoxy resin line markings and crosswalk markings throughout the project.
The construction baseline data provides detailed station information, northing and easting coordinates, curve data with radius and deflection angles, and line data with bearings and distances for the entire 58.7-station project length. The document specifies typical construction sections for both crowned and super-elevated roadway configurations, with reclaimed base material meeting specific gradation requirements per DOT 819 specifications. Catch basin replacement follows CTDOT standard details HW-0586-07A, HW-0586-07B, HW-586_07D, and HW-586-08 for various configurations. Drainage improvements include matching existing invert elevations and installing temporary bituminous concrete surface course reinstatement. The project includes environmental considerations with approximate wetland and 50-foot wetland upland review areas identified on the plans, and contractors must protect all excavations through appropriate shoring or bracing methods to prevent cave-ins or damage to adjacent structures and utilities.
