Engineering Consulting Services Christchurch
Our engineering consulting services are broad and cover a wide range of structural and civil needs. We work on projects using concrete tilt-panel and insulated sandwich panel construction, steel, timber, reinforced concrete block, and polystyrene block systems. These materials provide strength, efficiency, and durability, making them ideal for both residential and commercial applications.
We also specialise in seismic analysis of %NBS and detailing for strengthening, which is especially important in Canterbury given the region’s history with earthquakes. Beyond structures, our team provides sewer system designs, and stormwater drainage solutions. Soil investigation and foundation design are also part of our services, ensuring your project is structurally sound from the ground up.
