Attachment 4 - Site Investigation and Slab Report

 

NOTES

1. CONCRETE CLASS

CONCRETE TO BE CLASS N25 FOR SLABS & CLASS N20
FOR FOOTINGS & PIERS. 80 SLUMP. 20 NOM. AGGREGATE

2. CONCRETE COMPACTION

ALL CONCRETE TO BE MECHANICALLY VIBRATED FOR
COMPACTION IN TRENCHES OR FORMWORK.

3. SITE SOIL CONDITIONS

IF SOIL OR SITE CONDITIONS VARY FROM THOSE
INDICATED IN THE SITE INVESTIGATION REPORT THEN
THE FOOTING AND SLAB DESIGN SHOULD BE VERIFIED
WITH E.B.LS.

4, SCALED DIMENSIONS

DO NOT SCALE THIS DRAWING FOR SET OUT. REFER TO
DIMENSIONED WORKING DRAWINGS.

5. TERMITE MANAGEMENT.

PROVIDE TERMITE MANAGEMENT SYSTEM TO REDUCE
LIKELIHOOD OF TERMITE INFESTATION & TO DETER
CONCEALED ENTRY.

6. FILL COMPACTION

COMPACT FILL UNDER SLAB TO 65% SAND DENSITY
INDEX OR 98% STANDARD COMPACTION. USE ONLY CLEAN
SOIL - FREE OF ORGANIC OR COMPRESSIBLE MATTER.

7. ARTICULATION JOINTS

ARTICULATION JOINTS TO BE CONSTRUCTED IN ACCORDANCE
WITH “CONCRETE INFORMATION" FROM THE CEMENT AND
CONCRETE ASSOCIATION OF AUSTRALIA - TECHNICAL NOTE 61.

8. LOAD BEARING

LOAD BEARING WALLS SHOULD BE SUPPORTED BY SLAB
THICKENINGS. WHERE THIS DOES NOT OCCUR, VERIFY THE
DESIGN WITH E.B).S.

9. SITE INSPECTIONS

THE FOOTING & SLAB PREPARATIONS SHOULD BE VERIFIED

BY INSPECTIONS DURING CONSTRUCTION. WHERE PREPARATION
VARIES FROM THE DESIGN THEN ADEQUACY SHOULD BE
VERIFIED WITH E.B.1.S

10, HOT WEATHER CONDITIONS

DURING HOT OR WINDY CONDITIONS
ADDITIONAL PRECAUTIONS SHOULD BE TAKEN

TO CONTROL EVAPORATION, TO REDUCE THE RISK
OF PREHARDENING CRACKING IN CONCRETE,
THIS MAY TAKE THE FORM OF A SPRAY ON ANTI -
EVAPORATIVE AGENT AND ESTABLISHING A
TEMPORARY WIND BREAK

11, BLOCK WORK REINFORCING

VERTICAL STARTER BARS ARE TO BE PROVIDED TO COINCIDE
WITH THE LOCATIONS SPECIFIED BY THE DESIGNER. THESE ARE
GENERALLY AT ALL CORNERS, EITHER SIDE OF OPENINGS
AND AT 1200 MAX CENTERS AND ARE TO BE CAST INTO

THE FOOTING AND/OR SLAB

12, PLUMBING (STORMWATER & SEWER)

FOR “M, H1, H2 & E" CLASS SITES, PROVIDE ROTATION BENDS &
TELESCOPIC JOINS TO ACCOMODATE MOVEMENT OF SOIL
WITHOUT SEPARATION OF PIPEWORK. PIPEWORK FITTINGS SIMILAR
TO “STORMPLASTICS" (WITH RECOMMENDED PRACTICE) IS
RECOMMENDED. WHERE LARGE RUNS OF PIPE, SOFT SOILS OR
UNCOMPACTED FILL LOCATED UNDER SLAB, PROVIDE SUPPORT
FIXING TO SUSPEND FROM MAIN SLAB

13, REFERENCED DOCUMENTS

THESE DRAWINGS SHALL BE READ IN CONJUNCTION WITH
REPORT No. 210417-SI/FD BY EBIS

COMPLIANCE WITH DESIGN

FOR COMPLIANCE WITH OUR DESIGN, THE FOLLOWING
MINIMUM STANDARD FOR PIER/PAD FOOTING CONSTRUCTION
IS REQUIRED:

BASE OF PIERS ARE TO BE OF AT LEAST THE SPECIFIED DIAMETER

LOOSE SOIL IS TO BE FULLY REMOVED TO EXPOSE THE SPECIFIED
FOUNDING SOILS;

WHERE COMPLETE REMOVAL OF SOILS IS UNACHIEVABLE, THEN
DEPTH OF THE FILL SHOULD BE LIMITED TO NO MORE THAN 50mm
AND COMPACTED TO ACHIEVE AN ALLOWABLE BEARING CAPACITY
OF 200kPa

AS A GUIDELINE ONLY

FOR SAND:

A70 x 35 STUD SHALL NOT PENETRATE MORE
THAN 20mm USING GREAT EFFORT

FOR CLAY:

A N12 ROD SHALL NOT PENETRATE MORE
THAN 50mm USING GREAT EFFORT
