● CONTRACTOR’s Proposal attached as Attachment A.

It is intended that the specifications and plans, which include the Description of the Project on the first page of this Contract and supplemented as may be necessary by the DEPARTMENT, shall provide for the completion of the work specified herein.

The omission of specific reference to any minor items of material or work reasonably necessary to provide a complete project, will not release the CONTRACTOR from the responsibility of furnishing or doing the items omitted.

The CONTRACTOR shall leave the site free and clean of all construction equipment, materials, and rubbish. The CONTRACTOR shall replace any defective material or workmanship in the construction at no cost to the DEPARTMENT, and shall guarantee the construction for a period of one year from the date of the Department’s final acceptance.

ARTICLE 3 - TIME OF COMMENCEMENT AND COMPLETION

The time of commencement of work under this contract shall be within a reasonable period of time after the preconstruction conference as approved by the Department. The date of completion of the work under this contract shall be: 5/14/2027.

ARTICLE 4 - BASIS OF PAYMENT

The DEPARTMENT shall make payment within 30 days of receipt of a payment request which is approved as payable by the Department, on this contract as is indicated below, by one of the following methods:

1. Lump Sum Basis- This section is not applicable to this contract. Except for adjustments as provided for herein, the

DEPARTMENT shall pay to the CONTRACTOR, for the performance of work, the lump sum of $____________, hereinafter called the Contract Sum. The Contract Sum shall be equitably adjusted to cover changes in the work ordered by the DEPARTMENT, but not shown on the drawings or required by the specifications. Such increases or decreases in the Contract Sum shall be determined by agreement between the DEPARTMENT and the CONTRACTOR.

2. Unit Price Basis- This section is applicable to this contract. The DEPARTMENT shall pay to the CONTRACTOR the unit price amount stated with respect to each item of work on the attached schedule for the total number of units each item of work completed. The number of units shown on the attached schedule is approximate only, and the final payment shall be made for the actual number of units that are incorporated into or made necessary by the work covered by this contract. Should the number of units of completed work of any individual item shown on the attached schedule vary by more than twenty percent (20%) from the number of units stated, either the DEPARTMENT or the CONTRACTOR may request a revision of the unit price for the item so affected, but such changes shall not exceed 10% of the total Contract amount. Both parties agree that under such conditions an equitable revision of the price shall be made. Changes that cannot be classified under any of the contract units may be performed at mutually agreed upon unit prices, or on a lump sum basis.

The Department, under this Contract, shall reserve the right to withhold up to 3% consistent with Iowa Code Chapter

573. The Contractor may invoice the Department only for work completed. If the work extends over a period of more than one month, the DEPARTMENT may, upon request by the CONTRACTOR, make written estimates of the value of materials complete in place and the work performed. Estimates shall be on a monthly basis or on a longer period of time mutually agreed upon. No estimate, except the final estimate, shall be for less than five hundred dollars ($500). The estimates shall be figured at the contract unit prices for contracts on a unit price basis or on a mutually agreed upon percentage of the total work completed for contracts on a lump sum basis. Each estimate shall be filed in the form of a claim against the DEPARTMENT. Estimates are approximate only, and shall be subject to correction in the first estimate rendered following the discovery of an error in any previous estimate. Should a reasonable doubt arise as to the integrity of any part of the work completed prior to the final acceptance and payment, the department will deduct from the first estimate rendered, after the discovery of such work, an amount equal in value to the defective or questioned work. Further, such work will not be included in a subsequent estimate until the defects have been remedied or the
