This document is a pre-bid construction schedule for the Pratts Dam Road Creek Embankment Reconstruction Project in West Brandywine Township, Chester County, Pennsylvania. The project involves the replacement of existing retaining walls with soldier pile retaining walls, construction of a second soldier pile retaining wall, placement of rock protection along both walls, drainage improvements, full depth pavement resurfacing, safety feature upgrades, and associated work. The construction schedule spans from November 19, 2026, through May 30, 2029, comprising 41 distinct tasks with durations ranging from 1 to 222 days. Work is organized into two primary phases: Phase 1 focuses on Wall 1 reconstruction from August 2027 through July 2028, while Phase 2 addresses Wall 2 from July 2028 through December 2028. The schedule includes utility relocations with lead times for Verizon pole relocation (6 weeks) and PECO facilities relocation (16 weeks), mobilization activities, erosion and sediment control measures, winter shutdown from January through March 2029, and final construction inspection and closeout activities. All work is planned on a 5-day work week basis with 8-hour days, excluding U.S. holidays.

The schedule reflects a complex, multi-phase project requiring coordination of significant infrastructure work including caisson drilling, steel post installation, concrete lagging panel installation, temporary shoring, pavement excavation and milling, and asphalt binder and wearing surface installation. The project incorporates environmental controls throughout, with erosion and sediment control measures and pumped water filter bags required during both wall construction phases. Notable milestone tasks include detour notification and installation at project commencement, grading and topsoil placement following each wall phase, and final pavement markings and guide rail installation near project completion. The schedule demonstrates careful sequencing to manage constructability constraints, site access, and environmental compliance across the 30-month project duration.
