Product/System Evaluation

The  process of evaluating products is one of thorough review, analysis, testing and certified documentation.  Working with the TimberLogic team,  the submission process is of top quality.

Contact us for assistance with the preparation of appropriate documentation, quality control programs/manuals, engineering analysis and testing necessary to produce an evaluation report.

Evaluation of building products and systems involves many components that TimberLogic can provide:

  • Construction manuals
  • TimberLogic Reports (theoretical performance)
  • 3rd-party inspections
  • Quality control procedures
  • Independent physical testing (empirical performance)
  • ICC700 Green Building assessments
  • Evaluation to ICC400 Standard on the Design & Construction of Log Structures

Testing to Demonstrate Settling in Log Walls

posted Dec 27, 2012, 3:05 PM by TimberLogic LLC

Ed and Alex teamed up to develop the protocol for this test of log wall settling (photo below). 

The walls are assembled per producer specifications, measured, and loaded. Concrete weights rest on top of the log walls only. Measurement and moisture content probes are placed prior to loading into a steam-fired dry kiln (background). Each test assembly spends 21 to 28 days in the controlled atmosphere of the kiln prior to removal. Final settlement determination is made upon inspection and measurement of the wall assemblies following removal from the kiln.

Use ICC Evaluation Services' Evaluation Reports for Broader Acceptance

ICC Evaluation Services (

One way to improve the ability of your building product or system to gain approvals through building departments is to follow the Acceptance Criteria (AC) developed by ICC Evaluation Service (ICC-ES).  The various AC’s generally follow ANSI consensus procedures and incorporated contributions from ICC-ES staff, industry participants, and other experts.  These reports not only help building officials understand building methods and materials, but they support acceptance by design professionals and other organizations that use the product.

While there are a couple of competitive organizations (e.g., IAMPO, Architectural Testing) that provide similar services, Rob’s affiliation and experience with ICC has been fruitful in producing quality results.  As a member of the ICC-ES Advisory Committee, Rob also has participated in efforts to improve the services of ICC-ES. 

Examples of the results produced by the TimberLogic team (Rob, Ed and Alex) include AC233, Alternate Dowel-type Threaded Fasteners that has led to OMG/FastenMaster’s ESR-1078 and its updates.

Just as in the evaluation of a green certification, quality assurance is extremely important in this process.  One of the single most expensive elements of a submittal for an evaluation report can be the Quality Assurance Program.  The ICC-ES AC for quality control programs is clear and very detailed.  The importance of a third-party verification and enforcement of an on-going quality control program is required to insure that the evaluation report reflects performance of the product that is manufactured.  Changes made to the product without due process through the Quality Assurance Program can void the report.
