Testing labs in Shepparton, VIC

Downer EDI Works Pty Ltd is an Australian engineering and construction services company that provides infrastructure maintenance, design, and asset management across Australia and New Zealand. While primarily focused on roads, railways, airports, and bridges, the company operates testing and quality assurance laboratories as part of its construction materials and quality control operations. The company's testing capabilities are concentrated in geotechnical and civil construction materials analysis. Downer operates the Somerton QA Laboratory in Victoria, Australia, which holds ISO/IEC 17025 (2017) accreditation from NATA (National Association of Testing Authorities) since March 5, 1991. This facility specializes in testing aggregates, asphalt, concrete, and soils used in infrastructure projects. Additionally, Downer operates Road Science laboratories through subsidiary operations in both Australia and New Zealand, with IANZ (International Accreditation New Zealand) and NATA accreditation across multiple locations including Auckland, Tauranga, Wellington, and Christchurch. The Somerton QA Laboratory's accredited testing scope includes comprehensive evaluation of construction materials: aggregate property testing via particle size distribution and fine particle analysis per Australian Standards AS 1141; asphalt extraction and grading analysis using bitumen content evaluation and moisture determination per AS/NZS 2891 standards; and asphalt volumetric properties assessment including bulk density measurement, maximum density evaluation, and voids analysis. The laboratory also performs sample collection services including aggregate stockpile sampling and uncompacted asphalt sampling. Through its Road Science division, Downer provides expanded materials testing services including bituminous materials analysis (bitumen composition, residue, water content, viscosity, penetration, softening point, flash point, and durability testing) and performance evaluation (elastic recovery, permanent deformation, fatigue life, and abrasion resistance). Soil evaluation services encompass classification, compaction characteristics, dispersion, modulus testing, stabilization procedures, and pre-treatment analysis. Pozzolanic materials testing for lime analysis is also available through this operation. Downer's infrastructure and materials testing laboratories serve primarily road authorities, local government, and construction contractors requiring validation of construction materials and quality assurance for civil engineering projects. Services are conditionally available to external clients. The company's testing is aligned with Australian Standards, Austroads specifications, State Road Authorities requirements, and international standards. Real-time production testing during asphalt manufacture includes binder content verification, aggregate grading checks, and mix density evaluation, supported by field assessment capabilities including compaction checks and temperature monitoring. Downer's environmental credentials include Environmental Product Declaration (EPD) certification for their asphalt products, demonstrating third-party validation of sustainability claims.
