Case Studies
Expert Witness Service For Multi-million Delay
- Claims, Featured, Residential
HPM Consultants was retained to evaluate delays affecting the Dolores Huerta Gardens Apartment project arising from extended Southern California Edison (SCE) lead times and additional Solar As-Built Approval requirements introduced during construction. The dispute focused on whether these events qualified as excusable delays under the contract and whether the contractor was entitled to additional time-related compensation.
- Public / Municipal
HPM Consultants was hired to evaluate delays in the City of Ventura Veterans Project and determine the causes of the late completion. The review focused on whether owner-related issues, including switchgear and design delays, impacted the project schedule. The project completion date was extended by about 348 days beyond the original schedule. Questions also arose about whether contractor activities caused concurrent delays or whether the owner-related delays controlled the critical path.
- Public / Municipal
HPM Consultants was retained by the contractor of a municipal building to evaluate alleged project delays associated with construction activities. The analysis focused on determining whether soil remediation delayed project completion or whether other contractor-related events were responsible for the extended completion date.
The project involved multiple concurrent construction and tenant-improvement activities that experienced numerous schedule revisions, redesigns, and added work scopes. Soil remediation impacted completion, prompting an independent forensic schedule review by HPM Consultants.
- Multi-family
HPM Consultants was retained to evaluate delays affecting the Bowery Bayside Multi-family Apartment Buildings project, including extended punch-list corrections, work slowdowns, and prolonged completion activities. The dispute focused on determining the causes of significant schedule overruns and whether contractor performance and coordination issues impacted substantial project completion.
- Commercial
HPM Consultants was retained to evaluate delay claims associated with the Lakeside Equestrian Park project, including allegations related to building permits, sewer right-of-way access, and sewer connection design. The dispute focused on whether these issues delayed project completion and whether the contractor was contractually entitled to additional time and compensation.
- Commercial
HPM Consultants was retained in connection with River Street Marketplace Commercial Development delay dispute to determine whether alleged delay events materially impacted overall project completion. The assignment focused on identifying actual delay drivers, evaluating critical path impacts, and distinguishing alleged delays from other concurrent project activities.

Once a construction dispute moves into litigation, both sides typically depose the opposing expert before the matter ever reaches trial. A construction expert witness deposition is the moment every assumption behind a technical report gets tested directly, under oath, by opposing counsel.

Construction delays rarely stay isolated to a single cause. When an owner-caused delay and a contractor-caused delay happen at the same time, working out who owes what requires concurrent delay analysis, not a simple count of days. A Los Angeles construction delay expert witness deals with this exact scenario regularly, since overlapping delays are far more […]
