Commercial and development

Structural and civil engineering for commercial and development projects

For architects, building designers, builders, developers and council project teams across Geelong, the Bellarine and south-west Victoria. You see your model before anything is built.

Who we work with

  • Architects and building designers: structure that respects the design intent, with clashes sorted out in the model, not on site.
  • Commercial and industrial builders: engineering for design-and-construct jobs and tender pricing, with a model your team can price and sequence from.
  • Developers, surveyors and planners: civil and structural input from feasibility through to council engineering conditions.
  • Council and water authority project teams: design for community buildings, pavilions, change rooms, structures and site civil works.

What we design

  • Warehouses, factories, workshops and industrial sheds in steel, concrete and timber
  • Shops, offices, fit-outs and alterations to existing commercial buildings
  • Multi-unit and mixed-use buildings
  • Mezzanines, platforms, canopies and equipment supports
  • Retaining walls and footings on difficult and reactive sites
  • Car parks, pavements, site grading and stormwater, including on-site detention
  • Subdivision roads, drainage and lot grading

You see your model

Every structure is designed as a 3D model using Building Information Modelling (BIM). Your design team, builder or project manager can walk through the structure and check it against the architecture and services before construction drawings are issued. The drawings and computations come from the same model, so what you review is what gets built.

Software includes Autodesk Revit, AutoCAD, Advanced Steel and Civil 3D.

Designed to the right Standards

Commercial and multi-unit buildings (NCC Volume One, Class 2 to 9) are designed to the commercial Australian Standards for loading, concrete, steel and timber, not to the domestic housing Standards. Where a Standard has limits on building class, wind or height, we flag them early so there are no surprises at building permit.

How a project runs

  • Brief: send the drawings, sketches or tender documents you have.
  • Fee proposal: a written scope, programme and fee, so everyone knows what is included.
  • Model and design: we build the structure in 3D and share it with your team.
  • Documents: drawings and computations for your building surveyor, council or tender.
  • Construction support: answers to site questions and stage inspections.

You deal with the engineer who designs, checks and signs off your project. Principal engineer James Milne: B Engineering (Hons) RMIT, MIEAust, NER, RPEQ, Victorian Professional Engineer registration 2939.
