Written by GovTribe AI ·

This is a Design Addendum for the RTI Pedestrian Bridge Repair project located at Fort Carson, Colorado, prepared by Engineering Studio Denver (ESD/Veradyn Engineering, LLC). The addendum addresses drainage improvements and lighting modifications for the pedestrian bridge. Key construction requirements include installation of aluminum decking with NDS 5" Pro Series grates (5-1/4" wide) secured with stainless steel screws to existing landing joists, maintaining a 3/4" air gap between the decking at the exterior wall, and implementation of drainage details as specified in the schematic plans. The project also requires replacement of six light pedestals shown on the Existing Bridge Lighting Plan, with the general contractor responsible for preparing existing surfaces free of rust and painting the existing railing with an approved paint color as specified by the DMVA (Department of Military and Veterans Affairs).

The addendum specifies that the general contractor must ensure no trip hazards are present after installation, with notes acknowledging that air gaps may vary due to site conditions. The design documents are marked "For Review Only – Not for Construction" and indicate a project number of 10748 with a date of August 25, 2026. The drawings and plans remain the property of ESD and are limited to use on the specified project only without written permission. No specific pricing, funding sources, contract terms, or response deadlines are detailed within this addendum document.
