Services
Geotechnical Engineering
We maintain contact with leading academics and international consultants. This provides us with an up-to-date understanding of the latest investigation techniques and technological advances.
Geotechnical investigation services include:
- Site investigations, including specialist field testing such as Cone Penetrometer (CPT), Plate Loading Test, Pressuremeter, and Dilatometer
- Test pit excavations
- Geotechnical interpretations and provision of parameters for geotechnical and structural designs
Pavement Design & Testing
We provide a wide range of pavement investigation and design solutions including:
- Site investigation, testing and sampling to investigate subgrade conditions, or the condition and construction of existing pavements
- Residential road – Industrial hard stand area – highway and freeway
- Pavement designs, granular, bound or concrete pavements.
- Development of subgrade improvement options
- Residual life estimation and rehabilitation options for existing pavements
- Assessment of suitable pavement options and their comparative costing
- Detailed pavement design of options using CIRCLY
- Provision of subsurface drainage requirements
- Development of construction drawings and specifications
- Road pavement and construction supervision
- Benkelman Beam testing and Falling Weight Deflectometer testing
Landslip & Slope Stability Assessment
We provide landslip risk investigation and advice for properties and infrastructure asset owners where risk to landslip is a concern or are subject to an Erosion Management Overlay. A landslip risk assessment may involve surveying of the slope, engineering geological survey, site surveillance, drilling and soil or rock testing programs to assess the ground conditions.We can provide you with the following services, tailored to your site to minimise costs:
- Expert advice for property landslip risk
- Experienced and trained staff for infrastructure risk assessments
- Landslip investigation
- Back analysis & forensic investigation
- Stability monitoring
- Land instability management and monitoring advice
Laboratory & Earthwork Testing
We provide the following testing:
- CBR Testing
- Compaction testing – standard and modified
- Shrink swell index testing
- Sampling of aggregates
- Sampling from stockpile, pavement
- Particle size distribution
- Sieve analysis; material finer than 75μm
- Disturbed sampling from stockpile, pavement, windrow; undisturbed sampling
- Site selection by random and stratified random number
- Sample preparation; pre-treatment by repeated compaction
- Classification tests Section A2 (laboratory tests only) Moisture content (oven method, microwave); moisture content correlation method; liquid limit (Casagrande); plastic limit; plasticity index; linear shrinkage; particle density; sieve analysis; description, identification and classification of soils
- Fine particle analysis
- Hydrometer analysis
Instrumentation & Monitoring
We provide you with expert advice on instrumentation and monitoring for your next project. To increase reliability and reduce cost on any project or asset, engineers need valid and accurate and reliable data to analyse.
Geotechnical instrumentation and monitoring can be carried out manually using local logging or remotely depending on the data requirements and accessibility of the site.
Our consultancy services are tailored to your requirements and we provide integrated monitoring systems that can be connected to your existing system.
Environmental Assessment
Infradsign provides practical, innovative and cost- effective solutions with respect to contaminated sites throughout Australia.
Services include:
- Sampling, testing and classifying contaminated soil
- Analysis and disposal of contaminated soil in accordance with EPA Industrial Waste Resource Guidelines (Phase 1)
- Phase 2 environmental site assessments
- Review of current and historical site activities to identify potential areas for further investigation
Investigations we can conduct:
- Preliminary Site Investigation (Stage 1)
- Detailed Site Investigation (Stage 2)
- Remedial Action Plan (Stage 3)
- Site Validation (Stage 4)
- Salinity and Aggressivity Assessment and Management Plan
- Acid Sulphate Assessment and Management Plan
- Dam Dewatering/Decommissioning
Design of Geo-Structures
Geotechnical structures such as retaining walls, tunnels, deep foundations, coffer dams, earth dams and embankments are designed based on the interactions between the ground and the corresponding structures. We aim to deliver practical geotechnical designs that are both cost effective and safe.We assists by selecting the right geotechnical design parameters, running the design model with advanced softwares and verifying them during construction. The services provided by the geostructure design team include:
- Designing temporary or permanent structural systems, from prefeasibility to construction
- Carrying out design work of challenging nature that involves soil-structure interaction
- Providing input based on past experience in the design of deep excavation, vertical retention systems, tunnel portal using cut and cover method, top down or bottom up construction methods, or any other methods that suit clients needs.
- Planning, developing work and time schedules, including coordinating and directing resources on engineering projects to meed the deadlines
- Supervising construction works and certifying the completed works
Residential Engineering
Our engineering services involved testing founding soils for residential buildings.
Over time, our engineers have accumulated a wealth of knowledge in understanding the behaviour of soil and rock of various geological origins.
Identifying problematic soils allow us to design custom solutions to the advantage of our clients.
Tunneling Services
Infradesign is Australia’s leading geotechnical company with Australia wide experience, and highly qualified engineers and field technicians experienced with tunnelling works and infrastructures
