CIVIL ENGINEERING

Our team of experienced designers and drafters have a combined total of over 95 years experience in civil design, surveying and drafting fields.

No job too big or small

"

"

Our team of experienced design engineers have extensive technical understanding of typical council design guidelines and Ausroad/RMS design standards we incorporate this knowledge into our designs to ensure that all project objectives are met whilst remaining cost effective.

 

GDS will calculate the peak flow rates prior to commencing the design of main drains and watercourses.

 

We will then analyse these calculations as a primary consideration when determining the hydraulic grade for your site, ensuring the finished surface level of your developed land is designed to allow for overland water flow through drains and underground pipes.

 

GDS uses MUSIC Modeling (The Model for Urban Stormwater Improvement Conceptualisation ), a water quality tool which assists the planning and design of stormwater management systems, tailoring  to your land development needs, making sure you achieve water quality targets and requirements for your area.

 

GDS will accurately assess the performance of stormwater treatment devices and estimate pollutants generated, to provide expert recommendations on the most appropriate stormwater management system for your development.

We output a wide range of high quality detail designs and drawings consisting of:
