About this file

This file consists of engineering design plans and specifications for the Colonial Park Stormwater Improvements – Area C1 Dual Pipe project in Lower Paxton Township, Dauphin County, Pennsylvania. The project involves replacement and improvement of the existing storm sewer system, including storm sewer pipe, manholes, inlets, and endwalls, along with sanitary sewer lateral adjustments, pavement, curb, sidewalk, and driveway restoration, and erosion and sediment control measures. Bids for construction are being received online through PennBID until Monday, December 14, 2026, at 10:00 AM local time, with bid opening and results to be posted shortly thereafter. The design documents, prepared by Herbert, Rowland & Grubic, Inc., comprise seven sheets including site location maps, existing conditions and demolition plans, site improvements with proposed channel profiles, erosion and sediment control details, and construction specifications with multiple detail sheets addressing endwall types, storm sewer trenches, riprap aprons, seeding schedules, pumped water filters, erosion control blankets, and bypass pumping systems.

The project requires bid security in the form of a Certified Check or Bid Bond in an amount not less than ten percent. Prospective bidders are instructed to register with the PennBID website for access to all official notifications, addenda, and bidding documents, with telephone inquiries explicitly prohibited and all questions to be submitted through PennBID in accordance with the Instructions to Bidders. The documents indicate a revision date of November 11, 2026, and the engineer of record is listed as Herbert, Rowland & Grubic, Inc. of Harrisburg, Pennsylvania. No specific set-asides, incumbents, funding sources, or pricing terms are identified within the provided design documents.
