The split between a design engineer and a construction sub is where most geotechnical subcontract problems originate. The engineer's design doesn't account for the construction method. The sub's installation deviates under field conditions. The RFI cycle between them delays your project while you're managing three parties who each believe the problem belongs to someone else.
GeoStabilization International provides design-build geotechnical subcontracts where our in-house engineers and our installation crews operate as one team under one subcontract. The design is optimized for our construction methods. Field deviations are resolved by the same engineers who wrote the design. The closeout package is prepared by the team that built what's in it.
GeoStabilization International provides design-build geotechnical subcontracts across slope stabilization, earth retention, rockfall mitigation, and ground improvement scopes — combining PE-stamped engineering with self-perform construction under one subcontract price.
Slope stabilization scopes where the design isn't yet complete — or where the owner wants the sub to carry design risk — are delivered by GSI as design-build subcontracts. Our engineers develop the nail pattern, drainage design, and facing specification from the geotechnical boring data, and our crews install to our own design. One PE owns the design. One sub owns the construction.
Permanent and temporary earth retention systems developed from performance specifications are designed and built by GeoStabilization International. We select the retention method optimized for our construction approach and install to the performance criteria in your subcontract.
On design-build subcontracts, GSI manages the complete owner submittal cycle — from design calculations through material certifications and field QA records — under one project engineer responsible for both the design and the construction documentation.
Most prime contracts on geotechnical scopes create a liability gap: when the design-build outcome doesn't meet the performance spec, the designer says the contractor deviated, and the contractor says the design didn't reflect field conditions. That dispute cycle costs more than the original subcontract in some cases.
GeoStabilization International's design-build subcontract puts both the design engineering liability and the construction performance under one agreement. Our project engineer owns both the design decisions and the construction outcomes — and when post-installation monitoring confirms the system is performing to the performance spec, your owner's closeout acceptance reflects work designed and built to the same standard.
