Attachment 3 - Engineering Report · 51994.1391.01

Based on a visual inspection of the building, a review of the original building design drawings and a
review of the letter provided by the original design Engineer of the building, SCSE advises that
removing this wall will not have an adverse impact on the original structural design intent of the
building relevant to this location.

SCSE understands the proposed new wall is to be a double cavity 90/90 brick wall. SCSE advises that
provided this wall is constructed in accordance with the relevant Australian Standards, NCC and BCA
requirements suitable to that of an N2 wind location (after taking into account shielding
considerations), that the construction of this new wall in the location as shown in the below Figure 2
will not have an adverse impact on the original structural design intent of the building relevant to
this location.




                                            Figure 2 - Proposed Wall Location

SCSE advises that the brick cavity wall is to have medium duty wall ties between the veneers with a
maximum vertical spacing of 600mm and a maximum horizontal spacing of 450mm. The wall ties are
also to be fixed into the floor, soffit of the slab over and adjacent wall ends to adequately restrain
the edges of the wall.

SCSE also advises that a 200x10 traditional ‘T’ bar Galintel is required over the door opening. Both
the wall ties and Galintel are to be installed in accordance with the manufacturer’s specifications and
recommendations.

SCSE has not carried out any further review of the building design then directly applicable for the
above review and has not carried out an dilapidation survey of the existing building.

Please feel free to contact the aforementioned should you wish to discuss any of this further.



Yours sincerely

Dear Sir,

Re: PROPOSED ALTERATIONS TO UNIT 2, “BELLE DE JOUR”
24 EDGAR BENNETT AVENUE, NOOSA HEADS

| understand that you would like to relocate the external wall between the Study and
the rear patio out into the patio area so that the new wall location would be in line
with the rear wall of the adjacent bedroom.

| undertook the original design of the building and have re-familiarised myself with
the design using my original structural drawings. The wall is not a major supporting
wall and can be removed and relocated without affecting the structural integrity of
the building. The wall incorporates a sliding door and there appears to be a beam
over the door. This beam is constructed from concrete block and can also be
removed without affecting the structural integrity of the building.

The patio area is higher than the finished internal floor. This difference in level has
been created using a non-structural concrete topping and can be safely removed to
ensure the new internal area is the same level as the current internal floor. It should
be noted that underneath the existing sliding door location there is a concrete hob
constructed integrally with the main structural slab. This hob is not structural and
can also be removed. However, | would advise that a similar hob be constructed
under the new location of the wall and door, with the new hob being well bonded to
the existing slab and the finished hob and adjacent external surface treated with a
suitable waterproof membrane before applying floor finishes and installing the door.

Please contact me if you require any further assistance.
