Product Overview

This Safe Work Method Statement (SWMS) is specifically developed for Retaining Wall Construction, providing a structured approach to identifying hazards and implementing effective controls on Australian worksites. It is a comprehensive document that covers multiple aspects of retaining wall design, setup, construction, and finishing to support strong WHS compliance and risk management.

Activities & Specific Tasks Covered

This document includes specific risk controls for:

• Planning and design considerations for building retaining walls, including assessment of soil type, loads, and drainage requirements
• Construction of earth retaining structures, including stepped, tiered, and engineered retaining systems
• Installation of keystone block retaining walls, including safe handling, placement, and interlocking of modular blocks
• General retaining wall construction activities, including excavation, compaction, backfilling, and structural stability checks
• Selection and use of plant and equipment such as excavators, compactors, skid steers, and small cranes for wall construction
• Excavation near services and boundaries, including dial-before-you-dig checks and protection of underground utilities
• Management of work near edges, drops, and open excavations to prevent falls into trenches or over partially built walls
• Control of ground instability, surcharge loads, and potential wall collapse during and after construction
• Installation of drainage systems (ag pipes, scoria, weep holes, geotextile) to minimise hydrostatic pressure behind retaining walls
• Manual handling of blocks, formwork, reinforcement, and materials, with controls to reduce musculoskeletal injuries
• Use of concrete, mortar, and reinforcement, including mixing, placement, curing, and safe handling of cementitious products
• Traffic and pedestrian management around the work area, including delivery of blocks, aggregates, and concrete trucks
• Environmental controls for dust, noise, sediment runoff, and waste generated during retaining wall construction

Who is this for?

This SWMS is designed for landscapers, civil contractors, builders, concreters, block and brick installers, and site supervisors involved in retaining wall and earth retaining structure construction.
