PART 3 - EXECUTION


32 13 13 - 4

3.1 PREPARATION OF SUBGRADE: Scarify earth subgrade to a depth of not less than 6 inches and compact it to 90% percent of maximum density. 3.2 BASE COURSE: Spread and compact base course on prepared subgrade in accordance with paragraphs 26-1.04 and 26-1.05 of "Standard Specifications". 3.3 INSTALLATION OF CURBS AND GUTTERS: 3.3.1 Construct concrete curbs and curb gutters as indicated, with faces and backs formed for the full depth. Before removal of the forms finish the surface true to grade by means of a straightedge float, not less than 10 feet long, operated longitudinally over the surface of the concrete. Construct form clamps so as not to interfere with the operation of this float. Trowel the face of the curb smooth to a depth of not less than 2 inches below the flow line or to the flow line of integral curb and gutter, and then finish with a steel trowel. Finish the top gutter face and round the front and back edges as indicated. Give the curb face a final fine brush finish with brush strokes parallel to the line of the curb. Give tops of curbs a smooth trowel finish. 3.3.2 Provide expansion joints at ends of curb returns and at maximum intervals of 80 feet on straight runs. Provide weakened plane joints at maximum intervals of 20 feet between expansion joints. Use preformed joint material and edge with tool having a radius of not greater than 1/4 inch. Construct weakened plane joints to a minimum depth of 1/2 inch by scoring with a tool which will leave the corners rounded and insure a free movement of the concrete at the joint. 3.3.3 Finish top and face of curbs and curb and gutters true and straight, of uniform width, and free from humps, sags or other irregularities. When a straightedge 10 feet long is laid on the top or face of the curb or gutter, the surface shall not vary more than 1/4 inch from the edge of the straightedge, except at grade changes or curves. 3.3.4 Walkway Expansion Joints: Provide filler and cap per plans/details. 3.4 INSTALLATION OF SIDEWALKS, MOW STRIPS AND OTHER FLATWORK: 3.4.1 Preparation:

.1 Remove foreign matter accumulated in the forms.

.2 Rigidly close openings left in the formwork.

.3 Wet wood forms sufficiently to tighten up cracks. Wet other material sufficiently to maintain workability of the concrete.

.4 Use only clean tools.


32 13 13 - 5

3.4.2 Conveying:

.1 Perform concrete placing at such a rate that concrete which is being integrated with fresh concrete is still plastic.

.2 Deposit concrete as nearly as practicable in its final location so as to avoid separation due to rehandling and flowing.

.3 Do not use concrete which becomes non-plastic and unworkable, or does not meet required quality control limits, or has been contaminated by foreign materials.

.4 Remove rejected concrete from the job site.

3.4.3 Placing Concrete in Forms:

.1 Deposit concrete in horizontal layers not deeper than 24", and avoid inclined construction joints.

.2 Remove temporary spreaders in forms when concrete has reached the elevation of the spreaders. 3.4.4 Placing Concrete Slabs:

.1 Deposit and consolidate concrete slabs in a continuous operation, within limits of construction joints, until the placing of a panel or section is completed.

.2 Bring slab surfaces to the correct level with straightedge, and strike off.

.3 Use bullfloats or darbies to smooth the surface, leaving the surface free from bumps and hollows.

.4 Trowel surfaces to a uniform smooth texture free of trowel marks ready to receive final finishes as specified. 3.4.5 Joints: Tool the surfaces of flatwork to provide weakened plane joints in accordance with patterns indicated. Where no pattern is indicated, mark flatwork into rectangles not less than 12 square feet nor more than 20 square feet. Use a scoring tool that will leave the corners rounded. Form expansion joints 1/4 inch wide at all returns and opposite expansion joints in curbs. Where curb is not adjacent, form expansion joints at intervals of 60 feet. Fill expansion joints with premolded expansion joint filler. 3.4.6 Tolerances: The surface of flatwork shall not vary more than 0.02 foot from a 10 foot straight edge except at grade changes. 3.4.7 Broom finish: After concrete has been troweled and joints have been formed, use a stiff fiber broom to provide a uniformly straight scored surface at right angles to the general flow of traffic. Provide a medium broom texture at all exterior concrete paving, except provide a heavy


32 13 13 - 6

broom finish at ramps and walks exceeding 5 percent slope. Definition of medium and heavy broom finish will be as determined by the Architect at the time sample panels are reviewed. 3.5 DEFECTIVE WORK: Repair or replace deficient work as directed by the Architect and at no additional cost to the Owner.
