The commercial and residential property and construction sectors have seen some softening in Australia recently, however, engineering construction remains strong due to public sector demand.

Companies in this sector are dealing with increasing cost pressures and lower margins, and require timely and high-level environmental advice and technical expertise to comply with strict deadlines and avoid delays to development timeframes.

Senversa can assist companies in this sector from national portfolio clients to individual site owners through all stages of the property life cycle from pre-purchase to acquisition, lease, development and integration.

Our services include due diligence, risk prioritisation and liability assessment.


Detailed Soil Investigation Works

Senversa was involved in Stage 2 Redevelopment of Rod Laver Arena Melbourne Park delivered by Development Victoria (in conjunction with Lendlease as construction partner) to assess the underlying soil conditions, manage polluted fill and reclassify a large volume of soil for off-site disposal. Works were undertaken to meet strict project timelines and enable construction activities to progress on schedule.


Strategic Plan

Senversa developed a strategic plan for the redevelopment of a high profile inner city precinct (20ha) located on a large operational rail yard in West Melbourne earmarked for future sub-division. Senversa prepared a comprehensive ‘road map’ of contamination issues (including risk identification and management) allowing our client to prepare a robust environmental strategy as part of their business case.


Remedial Scheme

The site of the new state-of-the-art stadium in Paramatta had a significant legacy of environmental contamination as a former dumping ground for waste materials.  Senversa was part of a team responsible for developing the remedial scheme for the site impacted by approx. 20,000 m3 of soils contaminated with predominantly asbestos.  The remedial works were incorporated into the design of the new stadium and implemented as an integrated element of the development, specifically, soil excavated from eight known contaminated areas was capped as engineered fill in designated locations under the proposed main stands.  The stadium is due to opened in mid 2019.


Due Diligence

Senversa was initially engaged to complete a Due Diligence for a site to be developed into a high rise student accommodation. The investigation identified an underground storage tank containing chlorinated solvents associated with a former dry cleaner that had once operated on the site. Senversa provided ongoing contamination management advice, including soil remediation during construction, mitigation of vapour intrusion risk through completion of a risk assessment supporting the responsive design / installation of a vapour barrier and assessment / management of on and off-site groundwater impacts during construction. The assessments undertaken allowed the attainment of a Clean Up to the Extent Practicable (CUTEP) determination and completion of the Statement of Environmental Audit in under 18 months to allow facility to open on time for start of the 2019 academic year.


Detailed Site Investigation

Senversa provided contaminated land services to Potentia in Nuriootpa, South Australia where land formerly utilised as a brickworks was assessed under an environmental audit confirming its suitability for future residential use. The services ranged from preliminary to detailed site investigations including (but not limited to) soil and groundwater investigations and subsequent remediation and validation works. Senversa utilised their full team of expert risk assessors, hydrogeologists and environmental field scientists during the lifetime of this project and the land was assessed to be suitable for residential purposes by an EPA accredited site contamination auditor.
