PROJECT SIGN

PART 1 - PROJECT SIGN

1.1 Scope

Furnish labor and material required for the construction and painting of a sign as shown on the attached sketch.

PART 2 - GENERAL

The Contractor shall identify the project by means of an appropriate sign mounted in a conspicuous area of the work site, as indicated by the Contracting Officer or his designated representative. The sign shall be erected within 10 days of initiation of work at the job site.

The sign shall contain the following information in English:

a. Project No.

b. Project description

c. Constructed under Supervision of Base Civil Engineering

d. Contracted by 31st Contracting Squadron

e. Contractor

f. Design Engineer

g. Inspector

h. Contract Management: 31 CONS Construction Flight

i. ERP Coordinates

Lettering of the sign will be as shown on the following sketch, and may be painted or stenciled directly on sign. The sign will remain the property of the Contractor, and shall be promptly removed upon completion of the project.

Additionally, standard signs as per Italian Legislative Decree 81/08, and specifically per direction of the Safety Coordinator, will need to be installed at the site.
