PILING (PROVISIONAL)


The contractor shall take full responsibility for piling work and shall guarantee that piling work will support the calculated loads laid down by the engineer without injurious settlement. The actual lengths of piles shall be determined on site by the contractor in consultation with the engineer who will give all assistance possible. This does not in any way relieve the contractor of his responsibility or obligation to provide the specified guarantee.

Indemnity:

The contractor shall indemnify the employer against any injury to or death of any person and all loss or damage to all structures resulting from the failure of any pile. In the event of the failure of any pile the contractor shall make good such pile and all consequent damage at his own expense.

The contractor shall insure by means of a policy, approved by the principal agent, against risks arising out of the responsibilities, guarantee and indemnities specified. The contractor shall pay all premiums in respect of this insurance policy. The guarantee shall be for the amount and effective period as stated hereafter in this bill

The responsibility for the design and performance of all piles shall lie with the Piling Contractor and the Piling Contractor shall supply a 'Piling Guarantee' or a 'Piling Liability Insurance Policy' in this regard. The 'Piling Guarantee' or a 'Piling Liability Insurance Policy' is to be in place for a minimum period of 3 years after the final pile has been installed. The Piling Contractor's Pile Design Engineer must submit a 'Certificate of Stability' to the Principal Structural Engineer on completion of the piling contract

The 'Piling Liability Insurance Policy' should have insurance cover for the following sections :

1.Public Liability Cover2.General Construction Liability Cover3.Foundation Failure Indemnity Cover4.Products and Defective Workmanship Liability Cover5.The 'Certificate of Insurance' is to be submitted to the Principal Structural Engineer for approval.

The work comprises the design and installation of 31piles per block. The contractor is referred to drawing No 007-S-CRU-PILE issued together with these bills of quantities in order to acquaint himself fully with the nature and scope of the work

Piles are to be installed subsequent to the site beingexcavated or filled to the correct levels

Scope of work

Drilling

"Hard rock" shall mean granite, quartzitic sandstone or other rock of similar hardness, the removal of which would normally require drilling, wedging and splitting or the use of explosives

Classification of material

"Earth" shall mean all ground other than that classified as "hard rock" and shall include made-up ground and loose stones or pieces of concrete not exceeding 0,03m3 in volume as well as hard material the removal of which would normally warrant the use of pneumatic tools and which includes hard shale, ferricite, compact ouklip and material of similar hardness

General

Concrete grout strength for all piles at 28 days is 30MPa. Concrete cube tests to be carried out on pile grout for every 20 piles installed. 6 cubes to be taken after every 20 piles installed (3 cubes to be tested at 7 days and 3 cubes to be tested at 28 days). Results of the cube tests to be submitted to the Principal Structural Engineer for approval

Pile type is 250mm Ø pressure grouted Continuous Flight Auger pile (in 'end bearing') with a maximum service load of 603 kN

Pile cut-off level to be 50mm above soffit of the concrete ground beam or as indicated on the piling layouts with 500mm pile rebar projection

Pile integrity testing is to be carried out on all piles by an independent Geotechnical Engineer. No 'in-house' integrity testing by the Piling Contractor will be accepted.

All pile setting out is to be carried out by the Piling Contractor and verified by the Main Contractor whom assumes full responsibility for the pile setting out.All pile positions are to be set out by the Piling Contractor's registered Engineering Surveyor.

The final piling design is to be submitted by the Piling Contractor to the appointed Geotechnical Engineer for approval. The cost for this approval process is to be provided for by the Piling Contractor. The Piling Contractor can only commence with piling, pending the approval of the final pile design from the appointed Geotechnical Engineer and the approval from the Principal Structural Engineer.

The maximum permissible deviation of the pile positions shall be 50mm.

GRANOLITHIC

The method to be used shall be either the monolithicmethod or the bonded method

Method

For granolithic applied monolithically, the concrete floorshall be swept clean after bleeding of the concrete hasceased and the slab has begun to stiffen; any remainingbleed water shall be removed and the granolithic appliedimmediately thereafter. For granolithic to be bonded tothe floor slab after it has hardened, the slab surfaceshall be hacked (preferably by mechanical means) untilall laitance, dirt, oil, etc is dislodged and swept clean ofall loose matter. The slab shall then be wetted and keptdamp for at least six hours before applying thegranolithic

Preparation

Granolithic shall attain a compressive strength of at least 41MPa. The coarse aggregate shall comply with SANS 1083 and shall generally be capable of passing a 10mm mesh sieve. Where the thickness of the granolithic exceeds 25mm, the size of the coarse aggregate shall be increased to the maximum size compatible with the thickness of the granolithic

Panels

Where possible joints between panels shall be positioned over joints in the floor slab and shall be at least 3mm wide through the full thickness of the finish, separated by strips of wood or fibreboard and finished with V-joints

Monolithic granolithic shall be applied to the partially setslab and thoroughly compacted and lightly wood floatedto the required levels

Laying

Bonded granolithic shall be applied to the slab after applying a 1:1 sand-and-cement slurry brushed over thesurface and allowed to partially set before applying thegranolithic. The granolithic shall be throughly compactedand lightly wood floated to the required levels

After wood floating, the monolithic and bondedgranolithic shall remain undisturbed until bleeding hasceased and the surface has stiffened. Any remainingbleed water and laitance shall then be removed and thesurface steel trowelled or power floated

Granolithic shall be covered with clean hessian withwaterproof building foil over and kept wet for at leastseven days after laying
