Intrax Housing - Services - Intrax Consulting Group

Soil/ Geotechnical

Our soil services start with detailed subsurface investigations and site classifications in line with AS 2870. Every bore log, DCP result and probe reading is recorded in our central database. With experience nationwide, we deliver highly quality reporting.

Using mechanical drill rigs capable of drilling down to 8m, alongside probes and DCP testing, we accurately map soil profiles. We collect lab samples and conduct on-site compaction checks to confirm earthworks compliance. Survey data like slab heights and AHD links are integrated directly into our geotech models, reducing rework and producing quick turnarounds on reporting.

To support structural design loads and durability, we deliver wind-rating reports to AS 4055, detailed wind analyses per AS 1170 and snow-loading assessments tailored to local climate extremes. Corrosive-durability ratings to AS 3700 and salinity testing inform material selection and drainage strategies to mitigate long-term deterioration. BMO and LCA services reduce risk on everything from subdivisions to critical infrastructure. As part of our housing team, we offer true end-to-end services with in-house engineering, cutting costs and speeding up delivery.

Soil services we offer:

Surveying

Our surveying services support the full lifecycle of housing developments, from early stage contour and level surveys right through to construction and compliance work. We operate across greenfield and brownfield sites, delivering precise, reliable data to meet the high-volume and fast-turnaround demands of residential builders and developers.

Utilising state-of-the-art technology, including drones and 3D laser scanners, coupled with advanced software and digital platforms, we ensure rapid data capture, seamless collaboration and high accuracy. Our scalable model and integrated approach with geotechnical and engineering teams help reduce delays, accelerate approvals and support compliance throughout the build cycle.

Structural Engineering

Our specialised Housing Structural team delivers innovative, cost-effective and on-time structural engineering solutions tailored to the diverse needs of Australia’s residential and light commercial sectors.

We provide structural engineering design and consultancy across volume housing, boutique custom homes and light commercial structures. Our nationwide team of experts brings extensive experience across multiple sectors. Combined with in-house systems and quality processes, a dedicated R&D team and partnerships with leading Australian universities, we consistently deliver high-quality, on-time designs that are proven to reduce risk. Our scale and agility enable us to take on large, complex projects or standardised volume designs—supporting builders with responsive, reliable engineering at every stage.

Structural engineering services we offer:

Civil Stormwater Design

We offer full-service stormwater design for detached homes, duplexes, large multi-unit builds, NDIS housing and boutique projects.

From gravity-fed drainage and OSD to WSUD and overland flow, we tailor each design to meet site-specific and council-specific conditions. All solutions align with NCC and authority standards.

Our designs are coordinated with geotechnical, structural, and survey data to reduce foundation risks and improve constructability. Early engagement and collaboration ensure practical, cost-effective drainage outcomes.

Using Civil 3D, MUSIC, STORM, and custom tools, we deliver efficient, compliant designs. We work closely with builders and suppliers to ensure installation ease and first-time approvals.

Civil engineering services we offer:

Construction Stage Services (CSS)

Our CSS team supports builders during construction—resolving issues on-site with speed and expertise.

We handle slab rectifications, service clashes, design tweaks, and compliance concerns. With in-depth knowledge of the original designs, our engineers deliver code-compliant, constructable solutions that minimise delays.

Working closely with supervisors and trades—remotely or on-site—we provide practical guidance and hands-on help. Whether it’s a quick fix or major remediation, we act fast to keep projects moving.

Our engineers often resolve the same designs they created, closing the loop and improving outcomes across builds.

CSS we offer:

Energy Rating

Our Energy Rating team delivers fast, accurate, NCC-compliant assessments for all residential types and light commercial builds.

We provide energy and Whole-of-Home assessments for detached homes, Class 2 buildings, and medium-density projects. Whether you need a 6 or 7-star rating, BASIX, or a performance solution, we tailor the approach to suit your project.

All assessments are conducted by accredited NatHERS assessors using approved software to model designs and produce certificates. Our team works closely with your design and engineering teams to reduce iterations and achieve efficient, buildable, and compliant outcomes.
