Assessment Guidance

Learning Outcome 1:

Produce an annotated drawing of the construction technique for a free standing and a retaining wall summarising the differences.

Compare the benefits and limitations of 5 different bonds using SWOT analysis (Strengths, Weaknesses, Opportunities & Threats).

Compare the benefits and limitations of 3 different bricks and 2 different blocks using SWOT analysis

Learning Outcome 2:

Learners will mark out and excavate footings for a free standing brick wall
Construct a range of brick bond free-standing walls to centre specifications. Learners will construct returns and piers.
Learner to apply render to a smooth finish

Learning Outcome 3:

From a centre devised scenario student to produce a report for the customer explaining the various building regulations and planning restrictions for a proposed landscape wall construction.

Learners will explore the current building regulations and determine sources of accurate information. Legislation covering boundary disputes, party wall, heights, planning permission, conservation areas and listed property work explored.

Learners will produce a risk assessment covering health and safety legislation for the proposed landscape wall construction

Aim

The purpose of this unit is to provide learners with an understanding of how to construct and maintain walls.

The learners will be able to develop the skills, knowledge and techniques to construct walls in gardens and the landscape and comply with the health and safety regulations.

Unit Learning Outcomes

1.

Understand the construction of landscape walls.

Landscaping dwarf walling, types
• wall foundations
• facing brickwork
• rubble walling
• stone walling
• precast concrete structures
• timber structures
• fencing
• composite walls
• blockwork
• integrated drainage
• functions as retaining structures
• resistance to over turning
• single and one brick thick construction


Types of Bond
• stretcher bond
• English garden wall bond
• English bond
• Flemish bond


Specifications
The design specification for a wall that may include any of the following properties
• brickwork strength
• classification of engineering brickwork
• insertion of dpc’s
• foundation reinforcement
• brick sizes, metric , imperial
• type of mortar mix constituents e.g.(1:4, 1:2:4)
• type of pointing required, flush, bucket handle, recessed, weather struck
• drainage to rear of wall if used as a retaining structure
• thickness of wall and size of any supporting piers
• capping to top of wall to resist weathering


Walling materials
The application of different materials to create an aesthetic landscaping structure that functions as an independent wall or as a retaining structure
• use of engineering brickwork at ground level, Class A and B, red or blue
• facing brickwork, wire cut, hand made, recycled bricks, smooth finish
• coloured mortar
• pointing features
• use of solid concrete blocks
• rendering finish with external galvanised beads to blockwork

Assessment Criteria

  • 1.1

    Explain the difference in construction techniques for a free standing and retaining wall.

  • 1.2

    Assess the suitability and cost of a range of different bricks and bonds for a free standing wall in the landscape.

2.

Be able to construct landscape walls.

Wall construction, workshop simulation, work experience or employment

• excavation for foundation
• concreting of foundation
• construction of class B engineering brickwork courses
• construction of half brick walls
• construction of one brick walls
• construction of attached piers
• application of different bonding techniques
• pointing to courses
• insertion of retaining wall drainage
• backfilling to walls


Blockwork wall with rendered finish
• excavation for foundation
• concreting of foundation
• construction of class B engineering brickwork courses
• construction of 100mm walls
• construction of 190mm walls
• construction of attached piers in blockwork
• pointing to courses
• insertion of retaining wall drainage
• rendered finish to blockwork
• backfilling to walls

Assessment Criteria

  • 2.1

    Mark out and excavate footings.

  • 2.2

    Construct a single brick wall with attached pier.

  • 2.3

    Apply render to a smooth finish.

3.

Understand codes of practice and legislation.

Legislative constraints, Building regulations, Planning Permission

Planning Constraints: Application of planning law to landscaping works
• colour of walling
• height adjacent highway junctions
• conservation areas
• listed consent
• tree preservation orders
• flooding risks
• hard surface drainage
• natural drainage

Building Regulations: Application of building regulations approved documents to landscaping works
• associated landscaping drainage
• support structural elements
• party wall foundations
• external landscaping lighting

General Legislation
• Party Wall Act
• Health & Safety at Work Act
• Construction Design and Management Regulations.

Assessment Criteria

  • 3.1

    Explore building regulations and planning constraints for landscaping.

  • 3.2

    Explain the application of health and safety legislation to landscaping.
