Concrete Structure Investigations COVID-19 advice for clients


Hello valued clients and contacts,

Concrete Structure Investigation’s response to the Covid-19 Level 3 alert, with the upgrade to Level 4 Wednesday midnight:

CSI can continue to work remotely on your queries for pricing and completing reports where data has already been collected., as our team can work remotely on these and share electronically for peer review.

CSI can go to site where the work is for Essential Services, but we will not be able to attend non-essential site work until the current Level is downgraded.

As with the rest of the country, we are very sorry not to be able to progress your business requirements beyond the points above. We wish you all to be safe and let’s hope we can beat the spread of the virus and be back to work as soon as possible.

If you are contacting us about some pricing here are some really good tips so that we can get it right for you:

To assist CSI’s representatives with ensuring that we can provide you with the most cost effective, accurate and timely pricing and service we request you please share with us any information that you may have about the structure or building you are enquiring about. Sending us all drawings, photos and any other relevant information will ultimately benefit your project and allow us to be more informed. Please see below for a list of required information.

If you have any of the below information please share it with us

  • As built plans (Structural and architectural)
  • Scoping Documents
  • Photos
  • Hazzard registers and health and safety plans
  • Asbestos registers

If you have information and are unsure that it is useful please do send it to us regardless, to be able to provide our best service we require to be informed.

Please contact Kurtis 0800 33 77 67 if you have any questions.

Best regards, The Team at CSI

Material Testing

1. What is Material Testing?

CSI offers concrete and steel reinforcing bar properties testing through compressive and uniaxial tension tests, respectively. The test to determine compressive strength of concrete is conducted according to NZS 3112: Part 2: 1986 while the test to determine tensile strength of reinforcing bars is conducted according to AS/NZS 4671.

Additionally, CSI is also able to determine weld shear strength of mesh reinforcement, where the test is conducted according to BS EN ISO 15630-2.

2. When would you use Material Testing?

When you want to experimentally determine the properties of concrete and steel reinforcing material from existing reinforced concrete structures, for example because such specifications cannot be found or simply for quality assurance purposes.

3. What are the Benefits of Material Testing?

There are different purposes for knowing the properties of concrete and steel reinforcing material in existing reinforced concrete structures. For example, to be used in design calculations for structural upgrade, additional loading with significant intensities to be installed on the structures, or if there is concern about environmental effects on the original properties of the concrete and steel materials, such as chloride ingression to concrete or thermal exposure on steel reinforcement (i.e. in the event of fire).
