Services for Owners & ContractorsServices for LawyersCRI ProjectsOur TeamAbout Us

Services for Lawyers  
We are better than other "experts" because we have:
  • Experience on the stand
  • Experience in construction industry
  • Educational/engineering background
  • Scientific approach and methodology
  • Testimony based on statistics and engineering – withstands judicial scrutiny
  • Published work
  • The ability to be articulate under pressure
  Expert Witness
Construction Research provides what most other “expert” witnesses can’t—testimony based on statistics and engineering versus generalized experience and opinion.
Our expert witness services are fact-based and unbiased, withstanding tough judicial scrutiny.

In addition,
Construction Research is uniquely qualified to assist contractors in establishing entitlement and a remedy for labor and equipment related cost impacts. Our extensive study and documentation of labor productivity in steel framing, and installation/finishing of gypsum wallboard has resulted in an important publication that benchmarks industry standards.

Construction Claims Consulting
We work with owners and construction companies to:

Collect Information | Monitor | Analyze | Gather/Write the Claim | Support Legal Action if Required

  Construction Payment Claims
Construction payment claims grow out of the basic conflict that contractor (or subcontractor) believes he is forced to execute his work in a manner that is different and more costly than he expected when the bargain between the parties was made.

At Construction Research, we hope to become involved early in the project and help to resolve claims and avoid litigation, through diligent and accurate documentation of the changes and impacts.
It is always better, cheaper, and more efficient for all parties to negotiate a change order than process a claim.

Through our construction industry research activities, Construction Research is uniquely qualified to assist contractors in establishing entitlement and a remedy for labor and equipment related cost impacts; in particular, establishing a causal link between the alleged breach, and a loss or increase in cost of production.

We use multiple methods to calculate cost impacts including: scientific management models; project specific work process models; specific industry standards and studies: simulation; and cost based methods


Construction Research uses advanced methods and tools to provide an allocation of fault.
  Construction Defect Claims
The majority of the construction defect claims in the Pacific Northwest involve complex water intrusion and damage analysis.

Our construction defect service is distinguished from the “run-of-the-mill” construction expert firms in the way in which we use advanced operations research tools to provide an allocation of fault analysis.

Construction Research has also partnered with the Civil Engineering Department at Portland State University to analyze complex forensic engineering problems such as concrete wall and structural steel connection failures.

  Third Party Neutral Service

CRI’s Dr. Williams has been a registered professional engineer for nearly 25 years and has worked in the engineering design and construction industry all of his life. He has taught Construction Contracts and Law, Construction Management, and Project Management in the Civil Engineering Department of Portland State University since 1995, and has served as a Third Party Neutral, or Arbitrator, on a variety of construction related disputes.

We have a professional engineering background
of 25 years.
  Construction Industry Research
CRI has conducted research in the construction industry since its founding. We have applied advanced methodological tools such as: Delphi Process, Analytic Hierarchy Process, Data Envelopment Analysis, Simulation, as well as common and advanced statistical methods, to evaluate construction operations and impacts.

CRI founder Dr. Gerry Williams, studied the technical efficiency of project delivery systems used in the public building industry in Oregon from 1980 to 2000, and has delivered a number of lectures on the advantages and disadvantages of the different approaches. Recently the firm, in collaboration with Dr. Tim Anderson of Portland State University, has completed a major labor productivity impact study in the Metal Stud Framing, Drywall, and Taping and Finishing trades, which is published by the Northwest Wall & Ceiling Bureau and the Northern California Drywall Contractors Association. The firm, along with Dr. Anderson, is currently working on a similar nation wide study for the Finishing Contractors Association, which will include: commercial and industrial painting, glazing, floor covering, and finishing trades.



Dr. Williams is principal author, along with Dr. Anderson, of
“Impacts to Labor Productivity in Steel Framing and the Installation and Finishing of Gypsum Wallboard"
–a study sponsored by NWCB
and NCDCA.
