We specialize in the provision of structural, mechanical and piping (SMP) construction and maintenance services to greenfield, operational and shutdown projects. Through strong alliances and existing joint venture arrangements with allied services (civil, concrete, E&I) we are able to execute vertical packages on a turnkey basis.

KG adds value where possible through Early Contractor Involvement (ECI), using its breadth of experience to help assess and optimize the constructability of your design.
