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.

Every construction project starts with a plan, but plans rarely survive contact with real conditions on site. That is where the as-built schedule comes in, since it records what actually happened rather than what was supposed to happen. For anyone conducting construction delay analysis, this document is often the single most important piece of evidence in […]

In construction, a slower pace on-site doesn’t always indicate poor performance or contractor inefficiency. In many cases, contractors intentionally reduce productivity because an existing project delay has already made accelerated work ineffective. This strategic approach, known as pacing, helps avoid unnecessary costs while aligning work with the project’s actual progress.
