2411.01 DESCRIPTION.
This construction shall consist of furnishing and installing treated laminated floors in accordance with the contract documents and the following provisions.

2411.02 MATERIALS.

A. Lumber.
The floor strips shall be of the nominal dimensions shown on the plans. All floor strips shall be common class timber, either Douglas Fir or Southern Pine, meeting requirements of Article 4162.06, and shall be surfaced on four sides. All floor strips shall be treated with preservative in accordance with Section 4161.

B. Hardware.
Article 4153.07 shall apply.

2411.03 CONSTRUCTION.
Floor strips shall be placed on edge and securely nailed to preceding strips with at least one nail in each space between stringers or joists. The length of these nails shall be not less than 2.5 times the nominal thickness of the strips. For floors with wood stringers or with nailing strips on steel beams, each floor strip shall be nailed to each stringer or nailing strip with 20d (5.72 mm diameter by 100 mm long) nails.

When provided in the contract documents, laminated floors may be attached directly to steel beams by means of clips. Each clip shall be securely nailed to floor strips with not less than two 20d (5.72 mm diameter by 100 mm long) nails. Clips shall be positioned so they will hold the plank in close contact with top flanges of beams to prevent the plank from working loose due to relative movement between the plank and flanges.

Successive strips shall be placed and fastened to bear firmly on all supports and to be in close contact with the preceding strip. The space between any two adjacent strips shall not exceed 1/8 inch (3 mm). The surface of the completed floor shall show no variation in elevation greater than 1/8 inch (3 mm) between adjacent strips.

The ends of the strips shall be cut in lines parallel to the center line of the roadway.

Floor drainage shall be provided by means of crown in the roadway surface, when specified in the contract documents.

2411.04 METHOD OF MEASUREMENT.
The quantity of lumber used in laminated wood floors shall be computed by the Engineer in thousands of board feet (cubic meters) from the nominal widths and thicknesses of the strips and overall dimensions of the floor parallel to the length of the strips. Nails, clips, and other hardware will be considered incidental and will not be measured separately for payment.

2411.05 BASIS OF PAYMENT.
Laminated floors constructed in accordance with the contract documents will be paid for at the contract unit price per thousand board feet (cubic meters) for common class lumber as defined in Section 4162. This payment shall be full compensation for furnishing all lumber, hardware, and other material, and for the performance of all incidental work necessary to complete the structure in accordance with the contract documents.
