broken up by mechanical means such as rippers, jack-hammers or percussion drills.

Rippable Rock: massive pieces of rock equal to or exceeding 0.5 cubic metres with a smallest

dimension that exceeds 0.75m and that cannot be excavated at a rate exceeding 4.0m3 (bank) per hour

with a 75 kw backhoe of good working condition and operated by an experienced competent operator.

Non-Rippable Rock: Means all other rock.

Other than Rock: Other material encountered in excavation.

Sub-Grade: The natural ground below the excavations.

Filling: A general term for material spread and compacted over the sub-grade to make up finished

levels or levels to the under-side of the base.

Sub-Base: Selected filling spread and compacted over the sub-grade to make up levels to the underside

of the base.

Base: A selected filling layer spread and compacted to form an acceptable working surface directly

under the building.

4.105 Approval for Variations

Before starting excavation work which may involve a variation (whether addition or deduction) because

of the nature of the material to be excavated, obtain a determination as to the nature of the material from

the Principal. The variation is derived from the determination. If no prior determination has been

obtained, the variation, if any, is to be made only at the discretion of the Principal. The Contractor shall

measure and record the volumes, locations and horizon depths of rock that are encountered. Where the

Principal is unable to attend on site at the time rock is encountered to quantify volumes, the excavated



rock is to be stockpiled adjacent to the site for a period negotiated between the Contractor and the

Principal to enable the Principal to determine the nature of the material and the volumes.

4.106 Site Clearing

Remove from site progressively any debris or growth which may constitute a fire hazard.

4.107 Use of Explosives

Do not use Explosives.

4.108 Protection of trees

both above and below ground.

Give notice to the Principal and obtain instruction before repair of trees damaged during the work.

4.109 Work Near Trees

Take necessary precautions to protect trees specified or shown to be retained from damage by

groundworks, including the following:

A. Do not store, stockpile, dump, or otherwise place under or near trees, bulk and harmful

materials including oil, paint, waste concrete, boulders and the like. Do not place spoil from

excavations against tree trunks, even for short periods. Prevent wind-blown materials such as

cement from harming trees and plants.

B. Prevent damage to tree bark. Do not attach stays, guys and the like to trees.

C. Do not remove topsoil from within the foliage line of trees specified. If it is necessary to

excavate within the foliage line, use hand methods so that root systems are preserved intact and

undamaged. Open up excavations under tree foliage for as short a period as possible.

D. Do not cut tree roots exceeding 50 mm diameter unless necessary. Where it is necessary to cut

tree roots, use an axe or chain saw or similar means such that the cutting does not unduly

disturb or rock the remaining root system. Immediately after cutting, apply an approved

bituminous fungicidal sealant to the cut surface to prevent the incursion of rot or disease.

E. Avoid compaction of the ground under trees. If the ground under trees has been unduly

compacted during the work under Contract, for example for the operation of heavy

constructional plant, loosen the soil by coring.

F. Carry out coring by forming 75 mm diameter, 300 mm deep core holes at 900 mm centres for

the whole of the area affected and backfilling the core holes with sand watered in.

4.110 Site Investigation

The information given in the any attached report, or shown on the Drawings, or both, is information on

the nature of the ground at each tested part. It is not a complete description of conditions existing below

the surface. The accuracy of the information is not guaranteed and will not be a basis for cost variation.

4.111 Provisional Depths

The footing or strip depths shown in any attached Engineer’s Report or on the Drawings are the

minimum requirements. Approval of the Engineer and Principal is required for any variation to these

depths. If there have been variations to the Contract levels or dimensions of excavations, do not

vibrator heads clean and free of mud or other deleterious matter when inserted into the concrete.

Avoid contact of the vibrating head with surfaces of the forms.

7.310 Curing Concrete

After placement of concrete, exposed surfaces shall be kept continuously wet for a minimum period of

seven (7) days by covering with water saturated material. Protect freshly cast concrete from premature

drying and excessively hot or cold temperatures. Erect windbreaks in windy conditions to shield the

concrete surface during and after placing. Maintain the concrete at a reasonably constant temperature

with minimum moisture loss for the curing period.



Curing and Protecting Concrete: Cure as soon as the surface of the concrete has hardened sufficiently to

prevent damage but in no case later than two hours after the finishing operation has been completed.

Keep continuously moist by:

The use of waterproof paper or

The use of an approved polyethylene building film, or

The use of other approved moisture retaining covering.

Secure the covering material firmly against the concrete for the full length of edges and laps and at

frequent intervals between to prevent air circulation at the concrete surfaces.

Period of Curing: Continue for seven days for normal Portland cement concrete. For high early

strength concrete, continue for three days.

Prevent rapid drying out at the end of the curing period.

Spray strip footings, pads and similar finished items with ‘CalcureD’ or similar as recommended by the

manufacturer.

Chemical curing agents shall not be applied to any floor slabs that are scheduled for tiling or application

of any floor covering with adhesive.

wind pressure, effect of dead loads, without strain to glazing, without buckling of components and without

excessive stress to members or assemblies.

Contact with Other Materials: Coat metal surfaces in contact with mortar, concrete, plaster, masonry, wet-

application of fire-proofing and absorbent materials with an anti-galvanic, moisture barrier material. Isolate,

with inert material, dissimilar metals for the prevention of electrolytic action and corrosion.

Distortion: Design the glazed assembly to minimise visual distortion of reflected images.

PART III EXECUTION

25.301 Examination

Visit site and inspect conditions, comparing conditions to Drawings, before delivery of materials to site.

Rectify any discrepancy or unsuitability of substrate.


25.302 Conditions of Installation

Install backing boards or panels in accordance with manufacturer's precise instructions.

Rectify substrate so that when checked with a 2m straightedge, gap under the straightedge does not

exceed 6mm.

Allow new concrete to dry out for at least 4 weeks before rendering or direct fixing of tiles.

Floor screeds: broom finished.

25.303 Setting Out

As far as possible, set out work so that no tile less than half size occurs. Align joints in floor tile at right

angles to each other and straight with walls to conform to patterns selected. Verify locations of

equipment before installing tile. Co-ordinate with plumbing and other trades. Fully tile surfaces under

surface-mounted items.

Expansion Joints

Set out panels of tiling so that tiles may expand or contract to and from corners of tiled walls and floors.

Allow for expansion in each corner of 5mm minimum. Fill expansion joints with silicone as

recommended by the manufacturer. (N.B. expansion joint filler to be sufficiently flexible)

Control Joints

Provide control joint:

At junctions of dissimilar wall construction

In walls, no more than 2.5m apart.

25.304 Bedding and Screed Mixing

Tile fixing mortar is to be adequately cohesive and water retentive but not richer than 1:3 nor leaner

than 1:4 cement/sand by volume.



Within these limits the choice of the precise proportions is governed by the need to produce a mortar of

the required properties with the minimum water content. These proportions will depend on the sand in

use and is found by practical trial before tile fixing starts.

Once the proportions are established, make every attempt to minimise random variations. Batch by

weight wherever possible. Do not batch with shovels.

The mixing of mortars by a suitable machine is to be preferred whenever it is practicable.

Volume batching: Base batching on multiples of a whole bag of cement (50kg, approximating 0.035m3

or 35 litres). In such cases measure by volume using correctly made gauge boxes or other suitable

containers of fixed, measurable volume. This method allows water addition to be checked and thus

permits approximate mix proportions to be established and maintained.

Where mixing by machine is not possible, mortars may be mixed on a clean non-absorbent surface

using clean hand tools. Whatever method of mixing is used, blend the materials thoroughly in the dry

state before water is added. Continue mixing until the batch has a uniform consistency.

No water should be added once mixing is complete. Discard mortar which is unused within 2 hours of

adding the mixing water.

25.305 Bedding Methods

Portland Cement Bedding, Semi-Dry Mix Method:

Mix: One (1) part cement to four (4) parts of sand by volume, mixed dry, with only sufficient water

added to make a crumbly consistency which retains its shape when squeezed in the hand. It is important

to ensure complete mixing of the cement and sand.

Before laying the mix, establish finished floor levels by means of dots. Spread roughly to a thickness

slightly greater than that required for the actual bed.

Thoroughly compact and draw-off to the required level. Lay only sufficient bedding mix for one man to

deal with satisfactorily in one operation.

Pour a slurry consisting of one (1) part cement to one (1) part sand by volume with sufficient water to

make it slightly fluid, over the bedding and spread with a trowel until it is about 3mm thick.

Place tiles, which preferably are dry, in position and firmly beaten into the bedding. Form joints of at

least 2mm and regulating should be done at this time.

Wash off if necessary after the joints have set thoroughly.

Minimum bedding thickness 25mm.

Bedding with Adhesives (Walls Only):

Apply adhesive to a thin bed or thick bed according to site conditions:

Apply thin bed adhesives when the background is true to within 3mm when tested with a 2 metre

straightedge, at thickness not less than 1.5mm and not more than 3mm. Apply with a notched trowel.

Apply thick bed adhesives when deviations up to 6mm, over a 2 metre length, are present in the

background, or when applying tiles having deep keys or ribs on their backs. Thick bed adhesives should

be used at thicknesses not less than 3mm and not exceeding 12mm. Apply with either 10 x 10 x 10mm

notched trowel, solid bed or buttering method.

Application Methods:

Notched Trowel Method: Apply the adhesive to the background as a screed, then form ribs by combing

it with a notched trowel of the type recommended for the particular application. Do not apply adhesive

in areas larger than one square metre at a time.

Solid Bed Method: Apply the adhesive to the background as a screed and bring it to a true surface,

working in one square metre area at a time.

Buttering Method: Spread the adhesive evenly over the back of the tile to a thickness slightly greater

than the final bed thickness required, so that when the tile is pressed or tapped firmly into position, the

correct thickness is achieved and the tile is solidly bedded over its entire surface.

Apply dry tiles immediately into the adhesive, before it skins.

Press the first tile firmly into position and then remove it to check that complete contact is being made

with the adhesive. Make occasional similar checks throughout the tiling work. The whole of the back of

the tile is to be in good contact with the adhesive. Do not allow voids to occur beneath tiles.

Remove surplus adhesive remaining on the face of the tile or in the tile joints, after fixing, before it

skins.

Form joints straight and constant in width. Under no circumstances fix tiles with tight joints.

Allow tiles to set for a minimum 24 hours before grouting and protect from weather, water penetration,

etc. during this period.



Expansion Joints: Refer Clause 303 B, complying with AS 3958.1. See Clause below.

Cement based Adhesive method for extruded, quarry or terracotta floor tiles:

Secure to a prepared concrete surface with cement based adhesive 10mm thick with a 10mm notched

trowel. Comply with manufacturer’s current instructions

25.306 Installation - General

Wall tiling: Comply with the recommendations of AS 3958.1 and AS 3740.

Floor tiling: Comply with the recommendations of AS 3958.1 and AS/NZS 3661.

Adhesives: Comply with AS 2358 and recommendations of adhesive manufacturer.

25.307 Tolerances and Cleaning

General: Install tiles in true planes so that when checked with a 2m straightedge, gap under the

straightedge does not exceed 3mm. In sloped floor tiling this tolerance does not apply across

intersections of fall planes. Adjust tiles within 10 minutes of fixing.

Cleaning: Clean down using a damp cloth before cement smears and surplus mortar begin to harden on

the surface or in the joint spaces, care being taken to avoid disturbance of the tiles during the setting of

the bedding.

Lighting: Whenever possible the lighting at the time of applying the bedded finish is not to be

appreciably different from the ultimate permanent lighting.

25.308 Grouting

Except as otherwise required, do not commence grouting for at least 24 hours after placing of tiles.

Follow specific instructions of materials manufacturer.

Grout Mix:

General use, except as noted below: Apply an approved pigmented prepared grout mix, one (1) part

Portland cement to one (1) part fine dry sand by volume mixed to a paste consistency with the

minimum of water; too wet a mix may result in the joint filling cracking or drying out.

Floors: Prepared grout, acid resistive.

Walls: Epoxy-based mortar grout, mildew resistant.

Colours: as per Schedule or as selected by the Principal.

Grouting and Curing:

Apply the grouting mix to as large an area as can be worked before hardening commences. Apply with

a squeegee working back and forth over the area until the joints are completely filled. Remove surplus

grout from the tiles with the aid of a damp, not wet, cloth and the joints then tooled. After the grouting

has dried, final polish using a clean, dry cloth.

Remove surplus grout from the floor surface; on no account use sawdust for this purpose, as there is a

danger that sawdust entering moist joint surfaces may break down their strength, and cause them to

become porous.

In dry weather, grout joints after maintaining damp condition for three days by sponging down, fog-

spraying or other methods. Allow floors to set 48 hours before permitting ordinary foot traffic.

25.309 Protection

Prevent walking on or contact with floor or wall tiles for a minimum of seven days. During that period,

cover floor tiles
