Achievements:

In conjunction with our concreting subcontractor, Shamrock Civil created a formwork design that enabled faster stripping and forming of the planter diamonds which reduced time and cost.
Shamrock Civil developed a revised planter design in conjunction with ADCO Constructions to eliminate the requirement of the strata vault system which resulted in cost savings to our client.
