At Redco Consulting Professional Engineers we have been providing general engineering design and consulting services throughout New Zealand since 1993. Our services include structural engineering design, fire engineering design and seismic assessment and strengthening. We have offices in Auckland, Tauranga and Hawkes Bay and employ over 20 staff.

We have built a reputation for cost-effective solutions for building projects. We focus on building strong working relationships with our clients. Our dedicated team of professional engineers have extensive experience providing innovative solutions for residential, commercial, industrial and agribusiness developments. In addition we provide engineering design for other applications including swimming pools, tents, sunshades & canopies, retaining walls, container based buildings, prefabricated modular buildings and steel water tanks.

Our offices are well appointed with fully-networked computer facilities for analysis, design, draughting and general office duties. With these resources, no project is too small or too large for us. At Redco we are all about giving our clients an ingenious, cost-effective solution for their building projects.
