Providing Data

  • Leak investigations
  • Structural investigations
  • Materials identification and matching
  • Measurement of materials properties


    Investigations can occur prior to the creation of bid documents or to facilitate a change order.

  • Roof and facade moisture surveys
  • Deluge, flood, and leakage tests
  • Determination of rebar size, spacing, and cover
  • Non-destructive determination of concrete thickness and compressive strength
  • Location and marking of embedded reinforcement and conduit

    NDT&E investigations can provide quantitative data on the extents or specific causes of observed conditions. This quantitative data can be used to justify or focus a repair campaign, helping to prioritize budgetary allocations. Like exploratory probes, NDT&E can be used to investigate assemblies, but can provide that information at a macro scale, at more locations or even over an entire building envelope.

  • Analysis of concrete
  • Identification of stone
  • Mortar replication
  • Cleaning tests
  • Consolidation tests

    Materials investigations can provide information at the microscopic and chemical levels. Sampling may be the minimum to meet standards, or may be representative or statistical to confirm similarity or identify variations.


    Contractors use testing to meet project deadlines and budgets. NDT&E techniques are used to locate embedded elements, either for attachment, as with reinforcing anchoring, or for avoidance, as with waterproofing injection. In addition to contractually obligated testing as part of quality assurance and control, materials testing can be used to obtain approval of proposed equivalent products or techniques.

    Special Inspections

    For our own designs and for others, special inspections ensure conformance to contract documents and the structural integrity of the construction.

  • Structural Masonry
  • Wall Panels, Curtain Walls, and Veneers
  • Concrete - Cast-In-Place
  • Structural Cold-Formed Steel
  • Structural Stability - Existing Buildings
  • Underpinning
  • Fire-resistant Penetrations and Joints
  • Post-Installed Anchors
  • Exterior Insulation Finish Systems (EIFS)

    Forensic Investigations

    Sometimes we are brought on to a project during or after construction, either to test the effectiveness or quality of an implementation or to investigate an unexpected problem or condition. During forensic investigations we apply our expertise and arsenal of techniques to resolve disputes and provide guidance and insight based on objective data and criteria.
