SSPH 4.0 Bidding Specifications
1.0 INTENT
It is the intent of this specification to provide for the purchase of one (1) new and unused Slip-in Style Asphalt Heater to be used for the purpose of maintaining proper working temperature of hot mix asphalt.
The following specification is based upon a Stepp Mfg SSPH 4.0 Slip-in Style Premix Heater. The Public Works Department has evaluated different styles of asphalt hotbox equipment and has determined that this product is best suited for the DPW needs in terms of quality and features. This specification shall not be interpreted as restrictive but rather as a measure of quality and performance against which all other Slip-in Premix Heaters will be compared.
In comparing proposals, comparison will not be confined to price only. The successful bidder will be one whose product is judged as best serving the interests of the DPW when price, product, quality and delivery are considered. The DPW also reserves the right to reject any or all bids or any part thereof, and to waive any minor technicalities. A contract will be awarded to the bidder submitting the lowest responsible bid meeting the requirements.
2.0 EQUIVALENT PRODUCT
Bids will be accepted for consideration on any make or model that is equal or superior to the hot box specified. Decisions of equivalency will be at the sole interpretation of the DPW. A blanket statement that equipment proposed will meet all requirements will not be sufficient to establish equivalence. An original manufacture’s brochure of the proposed product is to be submitted with proposal.
3.0 INTERPRETATIONS
In order to be fair to all bidders, no oral interpretations will be given to any bidder, as to the meaning of the specification documents or any part thereof. Every request for such a consideration shall be made in writing. Based on such inquiry, the DPW may chose to issue an Addendum in accordance with local state laws.
4.0 GENERAL
The specification herein states the minimum requirements of the DPW. All bids must be regular in every respect. Unauthorized conditions, limitations, or provisions shall be cause for rejection. The DPW will consider as irregular or non-responsive any and all bids that are not prepared and submitted in accordance with the bid document and specification, or any bid lacking sufficient technical literature to enable the DPW to make a reasonable determination of compliance to the specification. It shall be the bidder’s responsibility to carefully examine each item of the specification. Failure to offer a completed bid or failure to respond to each section of the technical specification (COMPLY: YES NO) will cause the proposal to be rejected without review as non responsive. All variances, exceptions and/or deviations shall be fully described in the appropriate section. Deceit in responding to the specification will be cause for rejection.
