1 Gas Network Team Leader Unit SMLMAO12 Reinstatement of Modular Surfaces and Concrete Footways This unit is designed to allow the candidate to demonstrate the skills and knowledge required to carry out the reinstatement of modular surfaces and concrete footways. The candidate will be able to remove existing modular or concrete surfacing, to prepare the sub-base, to lay bedding materials and modular or concrete surfacing, using the correct equipment. They will also be able to identify and dispose correctly and safely of surplus materials, and materials that cannot be re-used. What does this specification look like? Gas network team leaders need to be able to: RMSCF1 Remove existing modular and concrete surfacing RMSCF2 Prepare sub-base RMSCF3 Lay bedding materials RMSCF4 Lay modular or concrete surfacing RMSCF5 Dispose of surplus materials RMSCF6 Follow safe working practices RMSCF7 Understand relevant health and safety guidance and legislation What do I need to take this module? Prior to taking this module, candidates should have completed all the following units: SMLMSW1, SMLMSW2 and SMLMSW3. Consideration should be made for the completion of SMLAOSW4 and SMLAOSW5. Candidates to be assessed as competent in this area must successfully meet the criteria listed below or have other unitary evidence demonstrating an equivalent level of competence. Evidence should be gathered from the workplace on at least one occasion Energy & Utility Skills Group Page 1
