Procurement Office - FAQ

The Airport Authority’s Procurement and Contracting Ordinance and State laws establish the legal authority for the operation of the Procurement Department. The Airport Authority’s Board holds the legal authority to award contracts in excess of $100,000. The Chief Executive Officer has been delegated the authority to award most contracts at or below $100,000. The Director of Procurement has been delegated the responsibility for the daily operation of the Procurement Department. The Airport Authority’s Procurement and Contracting Ordinance prohibits the actual purchase of any item or service without the proper authority, as evidenced by a contract or purchase order issued by the Airport Authority's Procurement Department. Therefore, the Airport Authority will not be responsible for payment of orders placed by anyone outside the Procurement Department. Orders placed without the proper authority will not be paid by the Wayne County Airport Authority.

The mission of Procurement is to meet the needs of our internal and external customers by: providing procurement support and advice to departments; providing accurate information to departments, citizens and vendors; and procuring goods and services that are of the best values so all departments may provide the most valuable and economical services.

Although a sealed bid technique is not used for informal requests for quotation, SFQs are made on a competitive basis by securing quotes from at least three (3) vendors whenever possible.

The Wayne County Airport Authority normally contracts for two types of purchases; one-time and term. One-time contracts may include goods and/or services and require a firm price for a fixed quantity. Term contracts may include goods and/or services to be delivered and/or performed on an as-needed basis, at fixed unit prices or fixed discount schedules.

Successful bidders will be expected to deliver the materials and/or services within the specified time. If delivery dates cannot be met, Procurement must be notified immediately. The Procurement Department will decide what action should be taken.

Vendors are advised that the Airport Authority requires proper labeling and Material Safety Data Sheets (MSDS) on all products covered by the Hazard Communication Act- 29 CFR1910.1200.

All formal bids and proposals are evaluated by the Director of Procurement or the designated Procurement representative, as well as the Requesting Department (end user). For bids, the award is made to the lowest responsive (conforms in all material respects) and responsible (has the capability to perform and the integrity and reliability which will assure good faith performance) bidder. For proposals, the award is made to the proposer whose proposal is deemed most advantageous to the Airport Authority based upon the evaluation criteria. After the award has been made, the Procurement Department will issue a purchase order to the successful bidder/proposer.

All shipments to the Wayne County Airport Authority must be made to the locations designated on the purchase order. Deliveries may be required to different Departments in various locations.

The purchase order number must appear on the shipping or delivery ticket, as well as on the invoice. Failure to meet specified delivery schedules may result in cancellation of the order.

A delivery normally must be made in the exact quantity called for on the purchase order. Partial deliveries, however, are required and/or accepted in some instances. The Airport Authority will make payment on partial deliveries when (1) a contract for the supply of goods, commodities, or contractual services extends over a period of months; and (2) authorization for payment is made by the receiving Department. In the case of any partial delivery, the shipping ticket and invoices must indicate the actual quantity being delivered and not the total quantity ordered by the Airport Authority.

In order to receive payment for goods or services furnished to the Wayne County Airport Authority, the vendor is required to submit an invoice to:

The Wayne County Airport Authority
Airport Finance Accounts Payable

Michael Berry Administration Building
11050 Rogell Drive, Bldg. #602
Detroit, MI 48242-5004

Invoices should not be sent to the Requesting Department (end user) or to Purchasing. Submitting the invoice anywhere other than to the Finance Department may delay payment. Invoices must show:

  1. Purchase order number;
  2. Complete descriptions of the goods or services furnished;
  3. Quantity;
  4. Unit prices and extensions;
  5. The discount terms;
  6. Name of Department to which shipment was made.
  7. The vendor's invoice number.

Once the vendor submits a valid invoice (see question above) to the Wayne County Airport Authority Finance Accounts Payable Department, the invoice is matched with the Airport Authority's receiving report and a copy of the purchase order. The Airport Authority’s Finance Department then issues a check for the amount due to the vendor. Correct invoices are usually paid within 14 days of receipt.

Vendors experiencing problems with their contract should contact the Procurement Office at (734) 247-7900.
