            Attention:       Nadine Gorton

            Dear Ms Gorton,

                    Re:      Information Request
                    At:      45 Maple Street, 4563

            With reference to the abovementioned development application and the subsequent
            information request from Council, we have prepared a response to the engineering matters
            raised as follows.

            Issue: Earthworks
            1. Provide additional detail demonstrating how the proposed earthworks will be
            undertaken to not undermine 7 & 11 Myall Street and 47 & 49 Maple Street and associated
            structures. The additional detail must be prepared by a suitably qualified person (RPEQ –
            Registered Professional Engineer of Queensland) and include, but not be limited to:
            a. demonstrate the construction methodology required to carry out the proposed
            earthworks; and
            b. demonstrate the structural integrity of the neighbouring structures and properties will
            not be adversely affected due to the proposed earthworks (cut).

            The proposed retaining wall, subsoil drainage and footings, including any temporary and
            permanent systems required during construction of the retaining wall are to be designed
            and certified by the geotechnical and structural RPEQ engineer as part of the detailed
            structural design. These systems – temporary and/or permanent – will be wholly contained
            within the subject site’s property boundaries and will not adversely affect the structural
            integrity neighbouring properties during installation (and/or removal, in the case of
            temporary systems) as is typical for constrained infill developments.

            A dilapidation report of the neighbouring structures may be conditioned prior to
            commencement of works to ensure no impacts arise to neighbouring structures as a result
            of the development.

            Issue: Sight Distance Analysis
            2. Provide a ‘Traffic Impact Report’ (or the like) and amended plans that demonstrates the
            proposed access is safe for all road users by complying with Austroads’ Guide to Road Design
            Part 4A. The ‘Traffic Impact Report’ (or the like) and amended plans must be prepared by a
            suitably qualified person (RPEQ – Registered Professional Engineer of Queensland) and
            include, but not be limited to:
