The expanding business has a growing £700m project pipeline, after securing a series of major built environment and water industry contracts during 2018.
It is now starting the hunt to find talented people to join its 1800-strong team across 12 UK offices, off-site build and fabrication facilities.
Head office expansion plans are also underway.
John Homer, chief executive of nmcn since 2016, said: “We are in a robust industry position and the launch of the nmcn brand signals the start of a new growth era for us.”
“Revenues have continued to rise, our cash position remains solid and a series of major contract wins are feeding our growing pipeline of work for the next five years and beyond.
“We are therefore looking to extend our team with an intensive recruitment campaign running over the coming months.”
Revenues have surged 76% during the last five years for the £340m turnover company.
Recent major contract wins include the £55m Bellozanne Treatment Works in Jersey, the multi-million Highways England’s Regional Delivery Partnership and South West Water Civil Engineering K7 Capital Works and MEICA frameworks.
Now working with 10 of the biggest water providers, Homer said several large-scale infrastructure contracts wins were instrumental in nmcn’s progression to becoming the largest multi-disciplined contractor in the water sector.
