Construction Engineering Services

OPAC maintain state-of-the-art tools for 3D analysis of construction configurations of complex modern bridge structures. We understand the unique requirements of building major bridges, from both design and construction perspectives.

Our proprietary technology enables complete project specific customization and rapid evaluation of proposed procedures for compliance with contract specifications. We can rapidly evaluate different construction options to determine which can best meet the needs of both the contractor and the owner. During construction, we can track geometry and provide on-the-spot recommendations for corrective actions in case of deviations.

We can evaluate stresses and deflections in precast, cast-in-place, and steel bridges built using any of the popular methods: cantilevering, span-by-span, incrementally launched, etc. For cable-stayed bridges, we have the capability to provide a refined cable stressing program that will minimize locked-in stresses and achieve the desired deck geometry with little or no cable re-stressing.
