Case Study: Utility & Drainage Survey with Confined Space Entry on Tier 1 Site

The Durkin team proudly delivers smart, safe, and effective solutions in complex environments. In a recent project for a Tier 1 construction site, we were engaged by a blue-chip client to carry out a detailed utility and drainage survey—a critical part of their planning and asset management processes.

Project Overview

The client required a high-accuracy utility and drainage survey to capture detailed subsurface infrastructure information on a highly active and tightly managed Tier 1 construction site.

While our survey scope was typical for a project of this nature, the challenge escalated when we identified several large stormwater pits on site that required confined space entry to properly assess internal pipe condition using CCTV tractor cameras.

The Challenge

To perform a compliant confined space entry, our team needed to secure an anchor point next to each stormwater pit to safely lower technicians and equipment into the space.

However, installing an anchor point in the ground near each pit would not only be cost-prohibitive but also time-consuming and disruptive to the site’s ongoing operations. Given the project’s tight timeframe and the client’s expectations around site access and safety, we needed to find a more flexible and efficient solution.

Our Solution

Our Project Engineer worked closely with our Plant and Equipment Hire Supplier to explore alternative options. Through this collaboration, we sourced a portable, certified anchoring system that met all confined space safety requirements and could be quickly mobilised to multiple locations across the site.

This innovative solution allowed our team to safely access the stormwater pits without the need for permanent infrastructure or additional groundworks.

Results Delivered

Using the portable anchoring system, we were able to:

• Set up confined space entry operations quickly and safely

• Complete all planned pipe condition assessments on time

• Avoid costly delays and additional groundworks

• Maintain full compliance with Tier 1 safety standards

The successful delivery of this project is a testament to Durkin’s ability to think on our feet, collaborate with trusted suppliers, and implement practical solutions that benefit both the project and the client’s budget.

At Durkin, we’re always looking for ways to deliver quality outcomes without compromising on safety or efficiency. Whether you’re planning a large-scale infrastructure development or need precision utility mapping on a sensitive site, our experienced team is ready to help.
