GBA Case History Series – Case History #113 - Challenge Yourself...Be a Consultant...Serve your Client...The GBA Story

Summary

A GBA Member Firm performed construction materials engineering and testing (CoMET) services for a new nine-story hospital. Another firm’s geotechnical report recognized the pavement subgrade would include poorly graded soil-rock fill and recommended a bearing ratio that the GBA Member Firm recognized as a “worst case” for design purposes. It became apparent early in the grading process that the fill should produce a higher bearing ratio. This conclusion, based on field observations made during construction, proved to be correct. Despite a lack of precedent, the GBA-Member Firm recognized an opportunity to save the owner a significant amount on asphalt paving costs by reducing pavement section thickness. This resulted in hundreds of thousands of dollars of savings. The result fostered a great relationship with a new client. Unfortunately, the Member Firm overlooked an opportunity to be fairly compensated for the additional risk and value derived.
