Total station for construction - GET3407
Overview
Duration
18 hours
Purpose/ scope
This standard covers the principles of using a total station for site surveying and setting out. These principles can be applied to all types of construction including earthworks, roads, houses, buildings, foundations, piles, structural steel, structures, and reinforced concrete.
Scope:
- Set up
- Calibration checks
- Sources of error
- Topographical Surveys
- Installing Primary and Secondary Control Points
- Using different functions
- Different methods for Plumbing Columns and Walls
- Data Management and Transfer
- Capabilities and Limitations
Occupational Relevance
Training delivered against this standard would be relevant to the following occupational group(s):
- Operative and Craft; Supervision; Management and Leadership
- Students studying Civil Engineering or Construction Management at any level
- Trainee and Graduate Engineers and Construction Managers
- Those who are already using the total station on site but have not had structured training
- Site Managers who would like to be able to supervise, recruit for, check or carry out setting out activities
- People with direct experience of the construction industry who would like to broaden their skills to include using a total station to set out
Learner Pre-requisites
No qualifications or previous experience is required; however learners are expected to be familiar with basic and co-ordinate geometry, Pythagoras theorem, angles and trigonometry
Instruction/ Supervision
- As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:
- A train the trainer or instructional techniques course certificate
- Successfully completed training to this standard
- A verifiable CV demonstrating a minimum of 2 years’ experience as a site engineer across a broad range of construction projects (civils, building etc.) and current experience / CPD in the use of modern topographical equipment
- A relevant Civil Engineering degree, HND or equivalent
Delivery
Delivery may be in an on or off the job environment with outdoor space to support a range of relevant practical related tasks.
All materials and equipment must be of a suitable quality and quantity for learner to achieve learning outcomes and must comply with relevant legislation.
The class size and learner/instructor ratio must allow training to be delivered in a safe manner and enable learner to achieve the learning outcomes.
- face to face learning environment only (Such as Classroom/Workshop etc.)
- a blend of face to face and virtual
- a blend of face to face and e-learning
This standard is predominately Practical
This standard is considered to be entry level
Assessment
Informally Assessed
For the successful completion of training, the trainer must be satisfied that the learner has achieved all learning outcomes.
Quality Assurance
Assured
Quality Assurance against this standard will require initial approval of the training organisation and their content mapped to the standard. CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the Training Organisation can meet the requirements of the Training Standard. Approved Training Organisations will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB Quality Assurance team.
