d) Pre-Fabricated footing cages or reinforcing bars at “T” & “L” intersections are to have a Y12 corner
lapping bar top and bottom and lapped 500mm with adjacent bars.

e) The minimum lap length of reinforcing bar is to be 500mm or 25 bar diameters, whichever greater.

7.0 ARTICULATION REQUIREMENTS:

The specifications in this report have been specifically formulated for articulated masonry construction.
This usually results lower construction costs. All masonry walls must have full height articulation at a
maximum spacing of 8 meters. The articulation joint must separate the masonry from footing to eaves
level at this spacing. Masonry must be supported on each side of the joint in an approved manner to
retain its structural integrity.

Where used, internal masonry wails should be articulated in accordance with the masonry manufacturers
requirements for the width and type of unit used. In no instance should the spacing exceed 4.0m and
articulation should always be provided at an abutment with an externa! wall.

{f articulation of masonry is found to be unacceptable, the footing system will require re-designing.

In addition to joints in masonry, articulation is achieved wherever a 10mm (min) separation in masonry
from footings to eaves is achieved. For example, where timber panels are used above and / or below
doors and windows.

Where it is necessary to construct construction joints to meet the articulation requirements, they can be
placed in places of limited visibility. For example behind downpipes. Internal masonry walls should be
articulated where they abut the perimeter walls. .

The designer of the building must also ensure that articulation is established:
1. Adjacent to a change in floor level which exceeds 400 mm.

2. If any proposed extension abuts any existing structure, full height articulation must be established
where the new masonry joins the old.

3. Where a masonry wall transgresses from one footing type to another - e.g. from a perimeter
footing to a continuous footing.

. If the building has any masonry arches we must be contacted for further advice.

Methods of articulation are well documented in “Technical Note 61° by the Cement & Concrete
Association.

8.0 LIMITATIONS:

Field Testing Limitations The soil profiles reported in our Log Section should be representative of
the soil conditions over this site. In some cases soil conditions may change dramatically over short
distances, therefore exploration programs may not locate all variations. If site excavations reveal soil
conditions that are different from those shown in the attached log sections we must be immediately
notified. Changes to the site classification and/or footing design may be necessary.

Previous Excavations The recommendations contained in this report have not taken into consideration
the long term effects of any previous, current or potential subsurface excavation mining or potential slope
instability problems. If a slope stability assessment is required for this allotment we can arrange for this to
be done, but that type of report is beyond the scope of our commission and fees in this report.

Client Supplied Information In writing this report we have considered all the information supplied to us
by the client. Should the client or his agent have omitted to supply us with relevant information our report
may be irrelevant and / or inappropriate. We do not take responsibility for the consequences in such
cases and we will make an additional! charge if as a result, more testing or re-writing of the report is
necessary.
