It’s the end of 2023, so we’re back once again with a statistical review of Constructive Evaluation’s year.

When it comes to foundation investigations and ground sampling, the are many methods Constructive Evaluation can employ to achieve desired results. One such technique is cable percussion drilling. This efficient practice is widely used in the construction industry for its ability to reach deep below the surface and provide invaluable information about soil and rock conditions.

Construction projects of any scale require a strong foundation to ensure the safety and structural integrity of the built environment. Geotechnical investigations play a crucial role in the early stages of construction, helping engineers and designers gain valuable insights into the ground conditions on which a project will be built

RAAC (Reinforced Autoclaved Aerated Concrete), has gained recent notoriety due to its potential dangers. In this blog post, we will delve into what RAAC is, highlight its associated risks, explore why it is banned across Europe, and underscore the significance of regular maintenance to mitigate any hazards.

This non-destructive testing method allows construction professionals to assess corrosion levels in reinforced concrete structures accurately. In this blog post, we will delve into the half cell testing method & its advantages

Trial pits (sometimes known as foundation pits, trial holes & trial trenches) are Constructive Evaluation’s most common geotechnical works. But what exactly are they and why do we use them?

This year marks Constructive Evaluation’s 30th anniversary. To celebrate the occasion, we thought we’d share with you the history of the company

In a change of pace from our usual blogs on the services we offer, this month we thought we’d review Constructive Evaluation’s year.

With Halloween upon us, we thought now would be the perfect time to look back at one of our more macabre projects. In late 2016, a council in London instructed us to undertake investigation and levelling works to 19 burial vaults in one of their former cemeteries

Rope Access External Defect Survey. A case study detailing the method, difficulties, challenges and solutions when carrying out a defect survey to the external elevations of a multi-storey structure

Jetty Structural Survey. A case study detailing the method, difficulties, challenges and solutions when carrying out a structural survey in a marine environment

It’s very easy to overlook the extreme loads fixings are put under. As such, it’s important to make sure that fixings aren’t going to fail. So, how do you test for something like that?

Our geotechnical team have been hard at work in London this week carrying out a plate load test. But what is a plate load test?

If you work in the construction industry, you’ll have heard countless times to be wary of asbestos. What you may not know, is that there are different asbestos surveys for different situations.

Window and windowless sampling are methods of soil extraction that retain the various horizons of the soil, so that they may be analysed, measured and profiled.

Whatever your building type from bridges to listed buildings, houses to nuclear power stations, Constructive Evaluation’s building surveyors have been involved in the structural investigation of a great variety of building types and are able to offer both intrusive and non-destructive testing to determine the existing construction form.

This week we’re going to be looking back at a dart rig job we undertook in 2019. This particular job was interesting because it highlighted the challenges of working in old buildings

Electromagnetic and GPR concrete scanning has become the preferred method of non-destructive reinforcement determination and inspection throughout the construction industry. To maintain structural and seismic integrity, engineers are frequently requesting that embedded reinforcement be avoided when cutting or coring through concrete structural elements.

Constructive Evaluation was recently commissioned to carry out a Site Investigation to an island situated on the River Thames. Before we could carry out our investigations, we first had to get to the island

In 2016 Constructive Evaluation Limited were instructed by our client, to undertake load testing to features on the Kew Gardens Great Pagoda
