Summary

The Member Firm performed a geotechnical engineering study for a major structure and recommended drilled shafts that would require permanent casing. The drilled-shaft constructor offered an innovative “value-engineered” approach to remove the casing and save money. Unfortunately, construction problems developed and resolution required extensive investigation, testing, redesign, and big dollars. Surprisingly, by sharing responsibility and costs, litigation was avoided.

Summary

The civil engineer retained the Member Firm to perform a geotechnical engineering study for a major municipal wastewater treatment facility but dictated a generalized scope despite a challenging site. After learning of unfavorable foundation conditions (near-surface rock), the civil engineer relocated a portion of the facility and directed the Member Firm to perform additional study but, against the firm’s recommendations, ignored the rock. The firm completed the additional study and the final report and construction began. Predictably, the Member Firm learned that the contractor had encountered rock and had submitted numerous change orders (CO) for rock excavation. Because the COs were rejected by the civil engineer, the contractor filed a claim for damages based on unforseen subsurface conditions. (Resolution was not reported.)

Summary

Member Firm provides geotechnical engineering services and CoMET for a new project on the site of an existing shopping center. CoMET services were provided “as needed” for demolition of the shopping center. A few years after the completion of construction, one of the three new retaining walls deflected significantly. Investigation of the backfill led to some surprises. On cue, the owner sued to reclaim the repair costs.

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.

Summary

A GBA Member Firm’s scope of services included a geotechnical engineering study and construction materials engineering and testing (COMET) services for a medical office building in area with old fill, expansive soil, and shale. During construction, the Member Firm was discouraged (“if we want your opinion we will ask for it”) from making suggestions and was only responsible “to enforce the plans and specifications as written and recommend alternative approaches only if specifically requested to do so.” A few months after construction ended, sidewalks began to move due to frost heave. The Member Firm and constructor in charge got the blame, which eventually led to mediation. The client’s former project engineer “spoke highly” of the Member Firm, which got them released from the litigation.

Summary

A GBA Member Firm performed an environmental site assessment (ESA) for a commercial real estate developer. After the Member Firm reported the laboratory tests, which indicated unacceptable levels of a contaminant, the prospective purchaser reneged and demanded a return of its deposit. After getting a second ESA from another laboratory, the Member Firm reviewed the second laboratory’s results and agreed that the initial lab did not record the results correctly, and the contamination levels were not as severe. Both the developer and prospective purchaser sued the Member Firm who, in turn, sued the other laboratory. The Member Firm prevailed against the initial lab but recovered less than half the total amount of the settlement it reached with the developer and prospective purchaser.

Summary

An architect for a church retained a GBA member firm to perform a limited-scope geotechnical study for a federally funded retirement home. Only boring logs and a brief letter report to the structural engineer were needed for the design of a pile foundation. Unfortunately, the design was not within the budget and the structural engineer refused to change the design and withdrew from the project. The replacement structural engineer redesigned the foundations and satisfactory load tests were performed but the federal agency balked until a geotechnical study was provided for the revision. A new geotech was retained but after the agency reviewed their report, the agency directed that a mat foundation be used. The church filed suit against the original member firm for the new costs.

Summary

The GBA member firm performed a preliminary geotechnical study to estimate foundation-construction costs for a small housing development. The project stalled and years later the developer sold the land with the geotechnical report to another developer. The new owner retained a different firm for a geotechnical study for the new project. When the new geotechnical firm identified problematic soils necessitating a deep foundation system, the new owner filed a $650,000 claim against the member firm alleging negligent misrepresentation. Adamant that the suit was unjustified, the member firm’s CEO finally acquiesced and accepted a $70,000 settlement offer from the new owner rather than risk the uncertainty of a jury trial.
