Addendum #1 - Loop Sensor Question.doc

This is Addendum #1 to an Invitation for Bid (IFB 6100064773) issued by the Pennsylvania Department of Transportation (PennDOT), Engineering District 5-0, dated November 5, 2025. The addendum clarifies bidding procedures and specifications for the furnishing and installation of loop detector sensors across six counties: Berks, Carbon, Lehigh, Monroe, Northampton, and Schuylkill. The solicitation requires electronic bid submission by November 13, 2025, at 10:00 AM. The contract scope includes three primary line items: furnishing and installing site traffic loop sensors (each), maintenance and protection of traffic (per hour), and separate pricing for nighttime and daytime work (per hour). The contract term is one year with potential two-year renewals allowing for a 3% line item increase per renewal period. Contractors must be capable of responding to requests within 48 hours and performing work simultaneously across multiple work areas.

The addendum addresses key pricing and specification questions from potential bidders. For loop sensor installation, which varies in size from 6x6 up to 8x50 feet, bidders are instructed to average all sensor sizes and provide a single per-unit price. For maintenance and protection of traffic, pricing should be calculated per flagger per hour, with bidders charging separately for each additional flagger if more than one is utilized on a project. Daytime and nighttime work rates are intentionally separated in the bid structure to allow for cost differentiation, though bidders may submit identical pricing if costs are the same. The issuing officer notes that individual counties within District 5-0 may have different processes but emphasized that bidders should simply place pricing according to the line item structure, regardless of county variations.
