OUR SERVICES

At EDC your project will be guided through each stage of the development and construction process by a multi-disciplined team of specialists, who are highly qualified and experienced in Civil, Structural, Fire, Geotechnical and Environmental engineering.

Our skills are appreciated by a wide range of clients including architects, developers, planners, surveyors and building owners.

Civil

From initial concepts to detailed design our civils projects include land development advice for a range of project types, including earthworks, stormwater drainage, water supply and environmental performance.

READ MORE

Geotechnical

Our team undertake geotechnical assessments and risk mitigation design for a diverse range of geohazards, including erosion, ground strength, liquefaction risk, slope stability, settlement analysis, ground improvement, retaining wall and pile design.

Structural

Highly experienced in a diverse range of small to large-scale projects, our track record for engineering excellence includes work on: multi-storey apartment buildings, offices, warehouses, factories, churches, schools, community facilities and residential projects.

READ MORE

Fire

Taking a detail-oriented ‘hands-on’ approach, providing fire engineering designs, construction detailing advice, and passive fire protection assessments for new and existing buildings from concept to completion

Environmental

EDC’s specialists in sustainable design and land contamination marry the need for safe, future friendly sites and development economy. From contaminated land studies, site remediation, energy Efficiency design to sustainable infrastructure.

OUR PROJECTS

We have a wealth of experience to offer, whether it be a new garage, multi lot subdivision or multistorey building. Our projects pages showcase this diverse work history input that has assisted in the success for our clients. These projects can be filtered to help you see projects similar to your own and give you the confidence that EDC are the design team for you.

Civil

By facilitating effective and sustainable use of natural resources we provide practical and cost-effective solutions to earthworks, roads and drainage .

Fire

Designing buildings to consider life safety and property protection in the event of fire is at the core of EDC’s specialist fire engineering service. 

READ MORE

Environmental

Our extensive understanding and knowledge of soil contamination, environmental standards and regulatory requirements, forms the basis of our cost-effective, innovative design service resulting in sustainable and safe sites.

Our Geotechnical Engineering Services

SITE INVESTIGATIONS

We carry out site investigations for all sizes of projects, residential and commercial, from small jobs that require hand auger equipment, to large-scale commercial and land development projects that may require supervision of deeper, machine-drilled boreholes and Core Penetration Tests (CPTs). We can organise specific field and laboratory testing of subsoils and rock, to obtain a detailed understanding of the variability of the ground beneath a site, including any possible contamination issues. This can be further expanded on by engaging contractors for geophysical (using ground vibration, ground radar, magnetic or induced potential) investigations if necessary

POST-EARTHQUAKE GEOTECH REPORTS

After a large seismic event, there is often a need to provide immediate and then longer-term geotechnical remediation recommendations. EDC’s Geotechnical analysis and reports provide design recommendations for immediate repair and ongoing ground stabilisation. EDC’s ‘earthquake engineers’ have first-hand experience in shallow and deep assessment methods, allowing us to assess geotechnical risks including liquefaction, slope stability and ground settlement.

SLOPE STABILITY ANALYSIS

Using our expertise in computer software to analyse the risk of future instability and our geological interpretation skills, we provide technically-sound and comprehensive advice for new developments on sloping land and remedial work on land affected by past, present or possible future instability.

GEOTECHNICAL DESIGN

EDC provides specific geotechnical designs to suit specific structure and ground interaction requirements including shallow and deep foundations, mass, segmental and cantilevered retaining walls. Our geotechnical experts integrate with our structural engineering section to provide the detailed calculations, producer statements, design drawings and specifications.

CONSTRUCTION MONITORING

We oversee earthworks projects, providing construction observation and field testing to examine and approve the progress in relation to the consent requirements. We certify the completed works and provide Producer Statements and Geotechnical Completion Reports, confirming the ground is appropriate for foundation designs. We also monitor retaining-wall construction, drainage, stormwater, sanitary and on-site wastewater disposal.

REPORTS

We provide geotechnical reports detailing site investigation and analysis findings, and provide comprehensive recommendations for earthworks, slope stability measures, retaining walls and foundations; essential for detailed structural design and the Building and Resource Consent application processes.

ON-SITE WASTEWATER DISPOSAL

Our geotechnical team work closely with our environmental engineers to carry out exploratory holes to identify soil types and suitability. This information is then compiled into a report to advise on solutions for on-site wastewater treatment and disposal systems for rural developments.
