This file contains the detailed construction plans and specifications for the 2026 Africa Road Underground Conduit Project in Westerville, Ohio, prepared by the Westerville Electric Division (WED). The project involves the furnishing and installation of approximately 6,100 linear feet of 2-5" Schedule 40 PVC Bore-Guard conduit and approximately 420 linear feet of 1-5" Schedule 40 PVC Bore-Guard conduit using directional boring methods across eight designated bore paths (A through H) along Africa Road, County Line Road, Polaris Parkway, Westar Boulevard, Atlas Avenue, and Carina Way. The work includes construction layout and staking by a professional surveyor registered in Ohio, maintenance of traffic in accordance with Ohio Manual of Uniform Traffic Control Devices standards, mobilization, site restoration including seeding and mulching, and coordination with the concurrent East of Africa Capital Improvement Project. Lane closures on Africa Road, County Line Road, and Polaris Parkway are limited to between 9 AM and 3 PM. The project completion date is September 18, 2026, with an engineer's estimate of $700,000.

The contractor is responsible for utility investigation, support, protection, and restoration of all existing utilities, including those from Communications Spectrum, City of Westerville (sanitary, storm, and water), Columbia Gas of Ohio, Insight Communications, City of Westerville Electric, American Electric Power, Breezeline, WeConnect, and AT&T. All conduits must be installed at a minimum depth of 48 inches below finished grade with minimum clearances of 1.5 feet vertically and 3 feet horizontally between all utilities. The contractor must call Ohio Utilities Protections Service at least two full working days prior to construction and expose and verify all utility crossings before and during boring activity. Potholing repairs shall follow City of Westerville standard drawings RD-14 and RD-15, all disturbed areas must be restored, and as-built plans marked in red must be maintained weekly and provided to the City upon project completion. The contractor must furnish only new materials, provide sanitary facilities for all personnel, secure all street plates with asphalt, maintain positive drainage on all new concrete and asphalt, and comply with all federal, state, and local safety requirements and NESC standards.
