Efficient Compaction Operators (ECO)
This course focuses on compaction in the field and industry 'best practice' to achieve a better result. This course has received outstanding feedback over the years and is fast becoming the industry benchmark for road builders and maintenance staff. This course will give your staff the knowledge and confidence to do the job right, first time.
Expected course completion time: 4 hours
$250 per student
Module One
Introduction to Compaction.
Introduction to road (pavement) theory and earthworks. Field compaction methods for construction materials. Detailed description of construction layers. Practical tips for machine operators. Practical guidance for technical staff.
Module Two
Materials used for civil construction.
Cohesive and granular soil types; their origins, characteristics and field identification. How to fix poor materials. Material grading and how it can be changed in the field.
Module Three
Soil mechanics including: wet and dry density and moisture content. Field techniques for wetting and drying. Field tests for Optimum Water Content (OWC). Layer thickness for construction materials. Primary compaction using vibration. Secondary compaction using weight and/or PTR. How to 'read' a roller to know when to stop. Plateau testing.
Module Four
Typical compaction field gear.
How they work. What materials to use them on.
How to recognise overuse of plant. How to recognise good compactors from bad ones. Plus a ton of good old tricks!
Efficient Compaction Advanced (ECA)
This is a course that is aimed at engineers, laboratory staff, and advanced practitioners. This course is a must for your technical staff if your business is building quality roads. Want to know more about construction materials and testing? This is the one for you!
Expected course completion time: 4 hours
$250 per student
Module One
Detailed introduction to the importance of understanding compaction. Implications of poor compaction. Design life vs actual life. Causation of some premature failures. Field compaction techniques and how they work. Materials from a geological perspective, including 8 soil types found in subgrades. How understanding geology is useful for civil engineering.
Module Two
Engineering soil classification.
Field identification of different soils, their characteristics and how to fix poor materials. In-depth review of soil mechanics including: density (wet and dry), moisture content (including field tests), air voids, specific gravity/solid density, CBR, shear strength, Atterberg Limits.
Module Three
Laboratory testing. Proctor/ compaction curves and the 3 techniques used to find MDD/OWC. Particle Size Distribution (PSD) and the different gradings (well, poorly and gap grading). Sand equivalent and how to interpret the numbers. Plastic limit, liquid limit and Plasticity Index. Using PI to establish stabilising techniques and binders. CBR testing including soaked CBR. This module will show you how to get clever with the numbers!
Module Four
Field testing and contracts.
We cover Scala penetrometer (DCP), Impact Testers, Shear Vanes, Nuclear Density Meters (NDM's) and more.
We show you the limitations of each device, and what they show you. Detailed Plateau Testing and how to get clever with it. Typical roading contracts pulled apart. Contractor responsibilities and requirements. Areas of ambiguity and how to address.
Nuclear Density Meter Users Course (NDMUC)
This course covers all you need to know about NDM's and their place in the industry. NDM's are used all over the world for site testing and the correct operation and understanding of the gauge is absolutely critical. This course will show your staff what it is, how it works, and how to transport and store the device - a must if your business uses NDM's
Expected course completion time: 4 hours
$250 per student
Module One
Gauge theory and introduction to the 'nuts and bolts' of the machine. What it measures in the soil. What the numbers actually mean. How the NDM generates the important numbers. Who can use the device. How the NDM works based on radiation theory, including decay and half-life.
Module Two
Technical guidance for density and moisture. How the lab numbers affect the NDM. What numbers need to be programmed into the NDM. Proof of how a NDM measures water content. Implications of NDM moisture measurements and how to correct these issues. Effects of stabilised materials with the NDM and how to fix.
Module Three
Modes of measurement for all material types. Backscatter and Direct Transmission. Standard Counts and how to deal with counts that have failed. How to prepare a surface for all materials. How to perform your testing correctly. How to program a NDM with correct laboratory numbers.
Module Four
Routine maintenance. How to clean the shield mechanism. Battery replacement. Calibration of your NDM; 3 block & 5 block.
Legal road transportation of your NDM. Storage of your NDM and record keeping.
Radiation Safety Officer (RSO)
A single module that covers the Office of Radiation Safety 'Core of Knowledge' syllabus for most non-medical applications. It is primarily aimed at RSO's who need to be appointed by the Managing Entity under the Radiation Safety Act, 2016. This course covers the requirements under C10 (X-Ray) and C12 (Radioactive) of the ORS Codes of Practice. Applicants will be required to complete the online quiz at the end of the presentation, and E- certs will be emailed to you. This course is also recognised as satisfying the requirements for a 'Use License' application, or those wishing to expand their knowledge due to Source Licensing and new legislation.
Expected course completion time: 3 hours

Note: Larger organisations or more than 15 participants will benefit from our onsite learning.
What people say about our courses
Finished the Compaction course yesterday with the team, and i must say it is by far the best course I have ever been on! For a one day course the knowledge you receive from Stu is gold dust or should I say lime dust? Haha.

Used Civiltrain NZ several times and look forward to doing so again in the future. Professional and knowledgeable. Makes for a very successful and stress free programme.
