At Gremalco, we partner with clients across road, rail, utility infrastructure, and subdivision projects. We work on upgrades, relocations, and augmentation of electrical, water and wastewater, gas and telecommunication network infrastructure to allow for the improvement and transformation of the communities in which we all live, work and play.

We’re family-owned, based in Western Sydney, and we like to think big!

Since 2000, we’ve helped deliver some of the largest greenfield and most complex brownfield construction projects in New South Wales, with project values up to $50m – and that makes us incredibly proud.

We’re also proud of the relationships we build with our client partners. They know that the earlier they get us involved, the sooner we can help them find the best solutions for their projects. As engineers, we succeed in finding opportunities that others overlook. We’re planners, forward thinkers and collaborators who anticipate (and relish) challenges! With us there are no surprises, we get in and get the job done.

We are proud to be an industry-leading utilities infrastructure and civil engineering company
