Background

Asbestos, a contaminant of the modern world once hailed as a product of the future asbestos was widely used in the building industry because of its cost, convenience and excellent heat insulation properties from backyard dunnies to factory roofs. Over time it was discovered to have serious adverse health effects particularly when airborne. While it has fallen into disuse (except in specialty products), because of the long lead times to discovery it is present is widely present in land fill everywhere from school playgrounds, sporting fields, recreation zones and demolished building sites.

It is considered important to remediate, where the extent of remediation required is dependant on the degree of contamination, knowledge of the contamination site and the intended and use in the future. While there is considerable fear in the community around asbestos, it is quite manageable.

Asbestos Remediation

Our Approach

Our approach has three main phases, each leading to the next and controlling costs through elimination of risks and knowledge acquired. Our approach enables you to have a good understanding of your suspected contamination and to enable you to effectively manage your site now and into the future. While the steps are common across remediation for any contaminant, our wide experience with asbestos allows us to deliver a timely cost effective solutions where you are in control of the process (and budget)

Preliminary Site Investigation (PSI)
Preliminary Site Investigations

This is a paper based study that investigates the known history of the site, including its use and can provide good evidence on the the scale (if any ) of the contamination. We also look to the neighbouring geography to look for cross contamination. For many clients looking to cover their bases this might be as far as you need to go. if you need to go further it is an effective tool in fine tuning your onsite testing to reduce time and cost required.

Contaminated Sites Evaluation
On Site Testing (DSI)

Based on the outcomes of our PSI or evidence you have collected from the site our next stage is to conduct sampling on site (a detailed site investigation – DSI). A sampling, analysis and quality plan (SAQP) is developed to make sure we sample the right locations and depths, and test for targeted types of contamination. Sampling may include soil, groundwater, surface water, building materials, or gas/air. We test general or targeted locations, and will often try and determine if any contamination has migrated off your site.

Risk Assessment and Remediation
Site Remediation

Based on the results our field tests and the intended land use we progress from a Tier 1 up to Tier 3 risk assessment. If that indicates an unacceptable risk to human and ecological receptors, we develop a customised remediation action plan (RAP) which assesses remediation options and outlines the best fit for the project and how the remediation should be implmented. Where appropriate we will engage technical specialists and contractors that we know and have used for many years and take care of all the management of the entire project, with regular reporting to you!
