2992 - Addendum No. 1.pdf

This is an Addendum No. 1 to ITB No. 26-2992-8EAR for the Tuckahoe Library Stream Restoration project issued by Henrico County, Virginia. The project involves restoration of a 600 linear foot stream reach utilizing natural channel design techniques, including channel bed raising, bankfull bench creation, and bank grading to slopes of 2 to 1 or less for stability. The restoration incorporates riffle, step, and pool cross sections designed using Virginia regional curve data and onsite bankfull data collection, with a B4c channel configuration featuring a steeper step pool sequence at downstream extents. Concurrent with stream restoration, sanitary sewer rehabilitation and pipe replacement will occur to address current exposure and degradation within the stream channel, with all denuded areas to be re-seeded, fertilized, matted, and planted with native woody stems and herbaceous cover. The project site spans three Henrico County-owned parcels and two privately-owned parcels located at Parham Road near Tuckahoe Library, with a total drainage area of approximately 65 acres comprised of 44 percent impervious and 56 percent pervious surfaces.

The addendum document provides modifications or clarifications to the original invitation to bid; specific pricing terms, set-asides, contract duration, and other salient details regarding the bidding process, response deadlines, and award information are contained within this addendum and should be reviewed in conjunction with the primary ITB document for complete procurement requirements and submission instructions.
