Managing soil issues can have an adverse impact on project delivery. We are undertaking research initiatives to identify key areas where project delivery can be improved to save time during the construction process. This time saving means that our clients can commence or recommence trading sooner resulting in potentially earlier revenue generation of up to $250,000 per week.
We are currently investigating and trialing environmental management strategies focusing on pre-classification, early treatment and cost effective removal from site to allow construction and fuel systems installation to commence as early as possible in the project timeline. This review is a nationally focused strategy. The areas of research are as follows:
- Comprehensive Preliminary Site Investigations;
- Pre Classification of soil contamination;
- Pre engineering geotechnical investigation and report for tank farm excavation stability, required batters and or benching requirements;
- Early HSSE risk assessment in relation to engulfment or cave-in;
- Conduct an in-situ investigation based on laboratory sampling, to delineate the extent of contamination and determine the volume and level of contamination before commencement of proposed excavation;
- Immediately treat as a pre-emptive measure with a product such as Biosolve to control odour and begin treatment process to reduce contamination levels;
- Stockpile soil in smallest piles increasing the surface area exposed to the air, sun and rain speeding up natural process of hydrocarbon removal;
- Separation of stock piles will reduce volumes requiring specific treatment and will significantly reduce the disposal and treatment costs associated with highly contaminated soil;
- Management of stockpiles to prevent cross contamination. Ensure that mixing of contaminated and uncontaminated soils does not occur. This will increase the treatment timeframe and will also result in higher disposal costs; and
- Earlier testing and faster results of soil classification.
We will report back findings to the Centre of Excellence for further discussion and dissemination.
