For over 35 years, Simcox Construction has made an impact throughout Marlborough and its surrounding regions. Today, we are part of the Isaac Group—a formation of companies all committed to providing the best possible service to our clients.

Originally formed in 1984, Simcox initially focused on drainage works, successfully securing the Marlborough District Council (MDC) Rivers Maintenance Contract in the early '90s, which we held consistently until 2024. This local knowledge of our waterways and weather events led to a number of high-profile flood recovery projects in partnership with MDC.

In the late '90s, we added wider infrastructure experience, including residential and industrial subdivision works, and vineyard development, which is now one of our core specialities. In the early 2000s, we acquired our quarry, Barrack’s Quarry. This asset supplies us with various roading and drainage aggregates, as well as large rocks for foreshore and riverbank protection.

Today, Simcox carries out the full spectrum of civil construction works with specialist knowledge across earthworks, drainage, quarry, surfacing, traffic management, and fleet teams. Numbering over 100 staff, we have the skills and experience to partner with you on civil construction works of any size.
