1.8 PROCUREMENT REQUIREMENTS

A. Invitation to Bid: Reference Form

B. Bid Form: Reference Form

C. Bid Bonds: AIA Document A310 2010 Edition Bid Bond shall be used. This form is approved

and recommended by the American Institute of Architects (AIA).

D. Contractor’s Qualification Statement: AIA Document A305 1986 Edition Contractor’s

Qualification Statement shall be used. This form is approved and recommended by the

American Institute of Architects (AIA). In addition to this form, contractor is to provide a

reference list of five school districts where they have completed re-roof projects similar to this

project in the last 5 years; include names, phone numbers, and email addresses.

E. E-Verify: U.S. Citizenship and Immigration Services; U.S. law requires companies to employ

only individuals who may legally work in the United States-either as U.S. citizens, or foreign

citizens who have the necessary authorization. This diverse workforce contributes greatly to the

vibrancy and strength of our economy, but that same strength also attracts unauthorized

employment. E-Verify is an interest-based system that allows businesses to determine the

eligibility of their employees to work in the Unites States. E-Verify is fast, free and easy to use-

and it’s the best way employees can insure a legal workforce. E-Verify will be used for this

project.

F. Experience Modification Rating (EMR): An insurance EMR rating is an indication of the

frequency and severity of past worker’s compensation claims. A company’s EMR rating

measures its past history of worker’s compensation claims against others businesses in the same

industry. For federal projects, contractors are required to have an EMR rating of .90 or less.

That is the rating requirement for this project.

G. Contract Labor: For this project, the roofing contractor will not be allowed to use contract labor

forces. All roofing work needs to be performed by the contractor’s employees. Sheet metal

work may be subcontracted to a company and must be listed on the bid form as such.

H. Prevailing Wage: For this project, contractor shall use the Missouri Division of Labor

Standards, Annual Wage Order No. 23, March10, 2016, Section 024, Clay County.
