STRIPPING, REMOVAL OF FORMS

Forms shall not be removed until the concrete in contact with them has hardened sufficiently to withstand such action without damage. Striking and removal of forms shall be carried out carefully and under the Builder’s direction to ensure the concrete is not jarred nor the surface damaged. The Builder shall take particular care in such striking and removal of formwork in areas which are to remain permanently exposed. The minimum stripping time for each reinforced concrete element whether post tensioned or conventionally reinforced shall be as directed by the Structural Engineer. Removal of bottom forms between bearers or props prior to the removal of supports may be permitted by the Structural Engineer, provided the formwork has been designed to allow such removal without disturbances of the supports. The contractor shall provide sufficient tomming to ensure that the loads caused by green concrete floors (not up to design strength F’c, as shown in the specification or on the drawings), formwork, building equipment and materials, is supported by such a number of concrete floors that no floor carried loads exceed its capacity. The number of floors to remain tommed will depend on the design dead and live load of the floors, the pouring cycle and the rate at which the concrete gains its strength. Neither walls, nor any permanent loadings, shall be erected on any part of the structure while any part is still supported by formwork.

Type CFF - Scratched Finish Floating shall begin when the water sheen has disappeared and or when the mix has stiffened sufficiently to permit the proper operation of a power driven float. The surface shall then be consolidated with power-driven float. Hand floating shall be used in locations inaccessible to the power-driven machine.

Type CRS - Steel Trowelled Finish Where a trowelled finish is specified, the surface shall be finished first with floats, as specified above, where applicable, then with power trowels and finally with hand trowels. The surface shall be thoroughly consolidated by the hand trowelling operations. The finished surface shall be free from any trowel marks, uniform in texture and appearance, and shall be planed to a Class A tolerance.

Type C - Integral Surfacing (surfaces to be carpeted) Screed off concrete immediately after pouring to the levels indicated, apply additional cement driers, dust over slab, work with wood float and finish with steel trowel to a smooth even finish.

Type CFB - Broomed Finish (External pavement slabs and driveways not scheduled to be finished) Give a coarse transverse scored texture by drawing a broom across the surface. This operation follows immediately after floating and shall be performed as outlined in Type CFF in the foregoing.

3.07 Curing & Protection

Freshly cast concrete shall be protected from premature drying and excessively hot or cold temperatures. CURING

All exposed surfaces of concrete (surfaces which are not in contact with forms) shall be cured as specified by the Structural Engineer.

PROTECTION

The concrete shall be protected from damage due to load over-stresses, heavy shocks and excessive vibration, particularly during the curing period. All finished concrete surfaces shall be protected from damage due to any cause such as construction activities, rain and running water. Self-supporting structures shall not be loaded in any way which will overstress the concrete.

34


3.08 Rejection

Hardened concrete shall be liable to rejection if the test strength of the sample is less than F’c specified, or if:

i. It fails to comply with the particular requirements specified herein or specified by the Structural Engineer

ii. It is porous, segregated, or honeycombed, or, iii. Its placing has been so interrupted that there is a construction or like joint not to

the Structural Engineer’s approval or, iv. The reinforcing steel has been displaced or, v. Construction tolerances have not been met or, vi. The required surface finish has not been achieved or, vii. The concrete can be shown to be otherwise defective.

3.09 Services In Concrete Work

All ducts, conduits, sleeves, sumps, bolts, boxes and cleats, etc...where shown on the Structural Engineers drawings are to be positioned on the formwork and are to be approved by the Structural Engineer.

Where pipes, conduits, etc. of outside diameter less than 25mm are embedded running parallel with the surface of the concrete, they shall have clear concrete cover equal to their outside diameter but not less than 40mm. They shall be placed so as not to displace reinforcement from its correct position, and shall be at least 100mm clear from any pipes, etc. The placing of pipes, conduits, etc. of outside diameter greater than 38mm shall be subject to Structural Engineers approval. All conduit or pipe layouts are to be approved by the Structural Engineer before work is commenced. These conduits or pipes shall be laid over the bottom reinforcement and under the top reinforcement.

See Contract drawings and other trades for necessary jointing between reinforced concrete work and/ or other materials. All expansion joints between two concrete surfaces and/ or between concrete and other materials are to be free of all contact and clear of the dimensions specified and are to be inspected and approved by the Architect before being covered and/ or filled with mortar. This applies to all expansion joints, vertical as well as horizontal. Where expansion joints in concrete are to contain

35


water seals in P.V.C. or metal designed and shown by the Engineer they are to be

dealt with as above.

3. 11 Construction Joints

The construction joints shall be located where indicated on Structural Engineers drawings and/ or where directed by the Structural Engineer. Reinforcement at construction joints shall be as shown on Structural Engineers drawings.

3. 12 Concrete Reduced Levels

Reduced levels shown on the Architectural Drawings are shown as either finished or structural levels. Before pouring any R.C. slabs, the Builder shall confer with the Architect for the set-down to be allowed for finishes. Structural floor levels shall be set out so that different adjoining floor finishes specified shall be flush. Where floor wastes are shown and where floors are shown graded to outlets allow for setting down the structural slabs to take extra thickness of grading required. Beams and slabs are not to be cranked but set down for their whole length.

3. 13 Floor Finishes

Refer to Architectural Drawings and / or this Specification, for superimposed finish to concrete floor slabs.

3. 14 Waterproof Membrane

The membrane shall extend under all edge thickenings and vertically up edge of slab, terminating approximately flush with finished floor level of the slab. The membrane shall be lapped at least 300mm, at all joints and taped with an approved adhesive tape at least 50mm wide. At all vertical junctions, the membrane shall be turned up the full depth of the slab. Reinforcement chairs are to be suitably cushioned to eliminate the possibility of puncturing the membrane. Any damage to membrane is to be repaired prior to the placing of concrete all to the approval of the Architect. The membrane shall be laid and/ or fixed immediately prior to pouring of concrete and where during pouring the membrane is pierced the pour shall be stopped and membrane made good before pouring recommences. Before the membrane is laid, the Builder shall ensure that the surface of the fill is compacted suitably smooth and to the Structural Engineers specification and obtain the approval of the Architect prior to commencement of the laying.
