To help guide you in the development process, please find below technical information.

REQUIREMENTS

Engineering drawings

Engineering drawings or reports are generally requested by councils as part of the design information specifying or justifying a development.

COUNCIL

Websites

The websites for councils in the far south coast of NSW which are geographically closest to us are listed below.

BUILDING DESIGN

BASIX certificate

BASIX (Building Sustainability Index) Certificates were introduced by the NSW government in 2004 as a control tool to help reduce the amount of water and energy use in residential buildings.

SITE CLASSIFICATION

Residential Slabs and Footings

A site soil classification to AS2870 (Residential Slabs and Footings) will generally be necessary for most residential dwellings.

FOUNDATIONS

Australian Standard AS2870

The Australian Standard AS2870 ‘Residential Slabs and Footings’ sets out the requirements for the classification of a site and the design and construction of footing systems for houses.

SLABS

Floor slabs

Floor slabs are constructed from reinforced concrete. The ground below the slab should have a damp-proofing membrane.

BEAMS

Support loads

Beams are used in a building to support loads such as those from upper floors, walls or roofs. They allow for larger openings or spans than would otherwise be possible with joists or rafters.

DRAINAGE

Stormwater Drainage Design

Most councils have guidelines on drainage design. Read for useful design resources online.

EROSION & SEDIMENT

Soils and Construction Volume 1

During construction in any development there is potential for storm events to cause erosion and the removal of sediment from the site.

RETAINING WALLS

Specifications for piers & walls

This project involved the design and specification of concrete piers to support an existing driveway and the specification of a reconstructed rock retaining wall.

ROADS & DRIVEWAYS

Junctions to main roads

Council will generally advise or provide conditions to a development application when specific design of junctions to main roads are required.

SEWER

‘Drains’ program and ‘Civil 3D’

Tasman Engineering Consultants can design sewer systems for your subdivision. We utilise the latest engineering tools using the ‘drains’ program and ‘Civil 3D’.

OSMS

On Site Sewage Management

On Site Sewage Management involves the disposal of wastewater entirely on land where that wastewater was generated.

STRUCTURAL INSPECTIONS

Local inspection services

Tasman Engineering Consultants can undertake structural inspections when requested by the Principal Certifying Authority (PCA).

FAILURE GALLERY

 Structural Failures

We are often asked to investigate structural failures and sometimes we just see them so here are a few photos.
