  • Friendly and experienced staff capable of finding the right solution, no matter the problem


How can we help you achieve the best outcome?



We have been involved in the BIM process for over fifteen years.  When BIM is introduced into the construction process, the method of project delivery changes completely.  A virtual model of the building developed prior to the construction process enables Engineers and modellers to solve design, co-ordination and construction problems in the model.  When this process is carried out fully, variation costs caused by rework and poor co-ordination is eliminated.  The model can also be used for programming and cost planning.

  • Achievement of outstanding design principles

  • Delivery of maximum value

  • On time delivery
