3.05 JOINTS
A. General: Where a construction joint is to be made, the surface of the concrete
shall be thoroughly cleaned and all laitance removed. Joint locations shall be as
shown on the plan and details with the following specifics and minimums.

shelter is provided, and during such weather, all concrete placed within the
preceding 12 hours shall be protected with waterproof canvas or other suitable
coverings.

1. Set edge forms and intermediate screed strips accurately to produce the
designed elevations and contours in the finished surface.
2. Screeds and forms will be sufficiently strong to support vibrating bridge
screeds or roller pipe screeds if the nature of the finish specified requires the
use of such equipment.
3. Align the concrete surface to the contours of screed strips by the use of
strike-off templates or approved compacting type screeds.
D. Float Finish:
1.Apply float finish to all unformed horizontal concrete surfaces.
2. After placing concrete, do not work the surface further until ready for floating.
3. Begin floating when the surface water has disappeared or when the concrete
has stiffened sufficiently to permit operation of a power-driven float, or both.
4. Consolidate the surface with power-driven floats, or by hand-floating if area is
small or inaccessible to power units.
5. Check and level the surface plane with a ten-foot straightedge placed on the
surface not less than two different angles.
6. Cut down high spots and fill low spots to produce a surface with the specified
finish tolerances.
7. Uniformly slope to drains where required.
