1st Ave N - The invitation to bid indicates: mill, underseal (chip seal), repave, and finishing with chip seal. - I don't see where the underseal or finish chip seal is indicated in plans, typical sections, surfacing summary, specs, or quantity. I assume no chip seal on 1/2" plant mix, but please clarify anyway.
Answer
Submitted: Thursday 29-OCT-2026 10:20 AM
The Invitation for Bid is outdated. There is no underseal or micro-milling in the project.
In the Proposal, the project descriptions and plan sets are correct.

A significant number of the sign locations are requiring removal of posts and foundations while replacing them with new posts and foundations in the same place. Because there is no demolition and replacement of sidewalks, the sign removal work will require unecesary demolition for removal of old bases only to be replaced with the same foundation and new pole of the same type. If the existing foundation and/or sign pole is undamaged, in the correct location, and of the same type as what is specified in the plans, will the Department allow the existing foundation and/or pole to be a Use As Is? The cost savings would come in the reduction of pounds paid for Posts Tubular Sq Perf.
Answer
Submitted: Friday 06-NOV-2026 08:48AM
Existing foundations and poles that are of the same type, size, and breakaway performance, are allowed to be used at the discretion of the project manager. The project is replacing multiple older style sign supports that are breakaway in a single direction with multi-directional breakaway systems. For each foundation and base approved for reuse, the payment will be for actual quantities used. If the foundation is not removed per 619 requirements on a “replace”, then a removal will not be paid. Only the sign sheeting and support if used.
This allowance is only valid for tubular steel square supports (PSST), all other supports are to be replaced as shown in the plans.

The project description in the Proposal states that this will be a scrub seal on both road sections, however the bid item for emulsion is CHFRS-2P. Is this a scrub seal or a standard seal and cover?
Answer
Submitted: Tuesday 03-NOV-2026 07:50 AM

The project description has been revised to reflect this: UPDATED PROJECT DESCRIPTION
As a result, the following bid items have been revised:

Can the state push the beginning of this work until March 1 or later in 2027? The railroad coordination often takes 12 weeks or longer and the temporary facilities permits would likely also not be approved by Feb 1 if they are started on before the project is awarded.

In the Request for Qualifications, Section V. SOQ Requirements, A. General, Paragraph g. The last sentence states: "The contractor, design professional, and key personnel assigned in the Design-Build Firm's SOQ cannot change after submitting SOQ, without prior written approval from MDT." Does this also apply to the Critical Support Staff in section B. Evaluation Criteria? This question is in particular reference to the Traffic Control Manager. Is it the intention of MDT to have the Firm choose a Traffic Control Manager before the price proposal thereby limiting the Firm in choosing between competitive subcontractors, or can this Manager be changed based on the most competitive subcontractor quote solicited by the firm?
