Do you need expert structural testing?

We have experience in a variety of structural testing situations from determining the structural properties of complete buildings to their components such as balustrade testing, barrier testing, glass testing, suspended ceiling testing and GPR concrete scanning.

Structural testing and analysis evaluates the integrity, strength, stability, and performance of structures. The goal is to ensure that structures can withstand the loads, forces, and environmental conditions they will face in use. There are several methods and techniques used in structural testing.

  • Load testing involves subjecting a structure to various loads to simulate real-world conditions and assess its behaviour.
  • Finite Element Analysis computer-based simulation technique used to analyse the behaviour of structures and components under various loading conditions. 
  • Dynamic testing involves subjecting a structure to dynamic loads such as vibrations or seismic forces. This is especially important in earthquake-prone areas to assess how well a structure can withstand these forces. 
  • Fatigue testing evaluates how a structure responds to repeated loading and unloading cycles.
  • Field load testing involves applying actual loads to a structure in its real-world environment. It is often used to verify the accuracy of analytical models and predictions.

The data gathered from these tests is used to validate design assumptions, make necessary adjustments, ensure safety, and ultimately contribute to the successful construction and operation of reliable structures.

Structural Testing services

  • Field testing of structures, structural elements and in situ connections to evaluate their strength, stiffness and earthquake resistance. We also assess the serviceability of buildings and floor systems impacted by forces associated with normal use.

  • Concrete durability testing using on-site and laboratory testing to assess carbonation depth, chloride ion contamination and diffusion.
  • Concrete core sampling, testing, and evaluation for compressive, tensile and flexural strength.
  • Steel reinforcement testing including concrete scanning for location, cover depth and assessment of corrosion risk, strength and Leeb hardness.
  • Structural element connection tests using economical small-scale tests to determine the mechanical properties of fixings and connections.
  • Post installation proof testing and quality assurance.
  • Other disciplines: Structural Engineers, Seismic Engineers, Fire Engineers.

Balustrade testing, Glass testing and Suspended ceiling testing for code compliance of new or alternative product systems

Our team of structural testing engineers have experience in balustrade testing, barrier testing, glass testing, and suspended ceiling testing and understand their critical role in ensuring the safety, function, and visual appeal of buildings.

Our experienced structural testing team has comprehensive practical knowledge of system compliance with New Zealand standards and building codes. We have performed code compliance and performance testing on a variety of non-structural elements in buildings such as:

  • Balustrade testing – balustrades and barriers primarily serve as safety features, preventing falls from elevated areas such as balconies, staircases, terraces, or mezzanines. They also contribute to architectural aesthetics and may have functional aspects such as noise reduction or privacy enhancement. Balustrade testing follows the Department of Building & Housing guidance on barrier design and New Zealand loading standards AS/NZS 1170.0
  • Glass testing – is becoming popular as a structural material in buildings due to its unique mechanical, optical, and aesthetic properties. Despite its growing popularity, there is a notable absence of design aids and comprehensive standards to assist in achieving appropriate structural designs for glass and glazing.  We can assist in designing structural glass and glass testing to NZS 4223.3.
  • Suspended ceiling testing – suspended ceilings play a significant role in enhancing the functionality, aesthetics, and comfort of buildings while providing practical solutions for concealing services, improving acoustics, enhancing thermal performance, and ensuring fire safety compliance. To ensure the safety of occupants, suspended ceiling systems must comply with standards and building codes. Suspended Ceiling testing adheres to ASTM E3090/E3090M-17 (or standards as specified by clients).

Our team of structural engineers conducts physical real-world testing in our own testing laboratory to provide accurate and reliable results.

Product Testing services

  • Code Compliance: Building codes and regulations dictate the design, materials, and installation of systems to ensure they meet safety standards. New Zealand building standards and codes may differ from regulations in other regions, so certification of alternative systems is essential to ensure compliance and safety. 
  • Real-World Simulation: Balustrade testing procedures simulate real-world scenarios including load/displacement testing of hardware, structural elements, and infill panels. Our rigorous physical glass testing is crucial in meeting industry standards and ensuring the compliance of your systems.
  • Suspended ceiling system testing involves applying loads to the ceiling system to simulate real-world conditions and assessing its ability to withstand these loads without failure. Structural integrity testing helps ensure that the grid system, suspension components, and ceiling panels are robust and durable.
  • Assured Quality: With our physical testing, you can be confident that your balustrade, barrier, or suspended ceiling systems meet the requirements of the NZ Building Code.
  • Other disciplines: Structural Engineers, Seismic Engineers, Fire Engineers

Do you need accurate GPR scanning on your project?

Using the latest equipment and techniques we can assist with all your GPR and concrete scanning requirements where accurate data is essential for effective design.

GPR scanning helps evaluate the condition of buildings and structures without damaging them. This technique can identify issues, assess their severity, and provide information for maintaining, repairing, or upgrading a structure. GPR concrete scanning is used to show the location of reinforcement and identify problems like cracking or corrosion. This knowledge is important to understand a structure’s health and identify potential issues that may require repair or updating. Additionally, concrete scanning can detect defects such as voids or hollow spots in concrete that may weaken a structure. Knowing where such problems exist in advance can help prevent damage or failure of the structure.
