EMIA S3EMIA-209-ATT2 AECOM SHE Construction Guidelines (Physical Construction SHE means and methods) AECOM SHE Construction Guidelines (Physical Construction SHE Means and Methods) (S3EMIA-209-ATT2) Revision 0 June 8, 2016 Page 1 of 233 PART 1 PHYSICAL CONDITION OF CONSTRUCTION PROJECTS AECOM SHE Construction Guidelines (Physical Construction SHE Means and Methods) (S3EMIA-209-ATT2) Revision 0 June 8, 2016 Page 2 of 233 PHYSICAL 1 – FALL PREVENTION 1.1 Design Risk Review 1.1.1 Constructability Where a design review or Constructability Review is to be undertaken. 1 Review 1.1.2 Risk Assessment The Contractors on site have completed a project risk assessment 2 including addressing work at height issues and eliminating the reliance of harnesses as the primary and sole means of work at height protection. Detailed Safe Work Method Statements (SWMS) should be prepared for all Work at Height. 1.2 Perimeter Protection 1.2.1 Edge Protection Robust physical barriers, such as screens, guard rails, and net systems 3 must be provided to prevent persons or materials falling any distance likely to cause injury, during works at height. 1.2.2 Exterior Work Work conducted outside of the perimeter protection must have lanyards 4 used to tie-off tools and equipment. Horizontal catch nets are installed as close to the construction operations as practical with exclusion zones established below. 1.3 Frame Erection 1.3.1 Metal Frame Metal frame structures must be erected from Mobile Elevated Work 5 Erection Platforms (MEWPs) and where access to the steel cannot be avoided, workers are to use beam gliders for access and safety nets and guard rail systems must be incorporated during metal decking operations. 1.3.2 Formwork Erection Concrete formwork/falsework systems should be proprietary systems and 6 are erected from safe working platforms or, are erected from below either manually or, through the use of MEWPs below the deck level. 1.3.3 Following Works Edge protection systems are designed as part of the frame erection 7 process and provide protection for following works (e.g. cladding). 1.4 Scaffolds, Temporary Works and Working Platforms 1.4.1 Working Platforms Scaffolds, temporary works and working platforms are planned, erected, 8 altered or dismantled by competent persons to ensure the right design and equipment is used for the specific situation. 1.4.2 Structural Integrity For scaffolds, temporary works and working platforms - all structural 9 members are free from visible defects, the structure is plumb, and adequate cross-bracing is provided. All scaffolds must be stable with sound footings, wheels locked (where fitted) and tied into structure where height/base ratio is greater than 3:1. 1.4.3 Safe Access All scaffolds and working platforms have safe ladder access provided. 10 AECOM SHE Construction Guidelines (Physical Construction SHE Means and Methods) (S3EMIA-209-ATT2) Revision 0 June 8, 2016 Page 3 of 233 1.4.4 Complete Decking All working platforms are closely planked, free from defective or damaged 11 planks and debris. 1.4.5 Protected Edges All scaffolds and working platforms have guard rails, mid-rails, and toe 12 boards installed on all open sides of platforms from which people or materials may fall. Where materials may fall over toe boards - netting or fencing is provided. 1.5 Penetrations, Risers and Shafts 1.5.1 Lift Shafts Openings to lift shafts are fully protected with a secure, full height system 13 preventing unauthorised entry and eliminating the risk of falls of persons or materials. Safe working platforms are provided for all those working in lift shafts. 1.5.2 Penetrations and Penetrations and risers are limited in size and number as far as 14 Risers practicable and have mesh cast in during construction or are fitted with other robust protection such as metal guard rails or covers, which prevent falls through them. 1.5.3 Floor Openings All floor openings are protected with robust, securely fixed (screwed or 15 bolted - not nailed) and clearly marked covers to prevent the fall of materials or persons through them. The covers do not present a tripping hazard. 1.6 Ladders 1.6.1 Use of Ladders The project team has undertaken a process to minimise the use of all 16 types of ladders and incorporated the use of safer means of working at height (e.g. scissor lifts, scaffold towers and podium steps). All ladders in use must be structurally sound, safely installed and used only as a means of access. Ladders in use must be stable, fit for purpose and use in a safe manner. 1.7 General Precautions 1.7.1 Securing Materials All construction materials that might be blown or swept off of roofs, 17 exposed floors or scaffolds are effectively secured when work has ceased and/or high winds are predicted. 1.7.2 Work around water Where water is present - additional measures have been taken to prevent 18 drowning. 1.7.3 Loading Platforms All loading platforms are assessed before installation and are fitted with 19 guard rails to all sides where people or materials may fall. All loading platforms must be checked to ensure there are no snagging points on them. If snagging points are found the platform must not be used until remedial measures were taken to remove the potential for snagging. AECOM SHE Construction Guidelines (Physical Construction SHE Means and Methods) (S3EMIA-209-ATT2) Revision 0 June 8, 2016 Page 4 of 233 1.7.4 Mechanical Access All mechanical access systems have guarding that is robust and fit for 20 Systems purpose. Restraining harnesses are worn and secured by persons working in MEWPS with articulated booms. 1.7.5 Rubbish Chutes Rubbish chutes and skips/dumpsters used for rubbish disposal (from 21 upper floors) are located and/or fenced off so as to prevent danger to the public and workers. 1.7.6 Suspended Access All persons working on suspended access (bosun’s chairs / cradles / 22 gondolas / swing stages) must wear and use appropriate independent fall prevention equipment to effectively protect them from any failure of the equipment or suspension system. 1.7.7 Vertical Access Access to general work floors is provided by the full permanent solution 23 where ever possible. Where this is not possible, temporary staircases of adequate width and complete with handrails are provided. PHYSICAL 2 – LOGISTICS 2.1 Site Access Control 2.1.1 Gate Entry All locations shall effectively control access to the site/premises to prevent 24 unauthorised persons entering. 2.1.2 Recording of all All persons (workers and visitors) entering and leaving the location should 25 Persons be recorded for accounting purposes in emergency situations. 2.2 Fencing 2.2.1 Site Fencing All construction works in the vicinity of members of the public must be 26 fenced off to prevent unauthorised access. All works lasting more than a few hours should erect suitable fencing or hoardings to prevent unauthorised access. 2.2.2 Entry Signs Access points and site rules should be clearly signed. 27 2.3 Public Protection 2.3.1 Lifting Operations The project must ensure that the public is excluded and/or protected via a 28 suitable physical barrier during lifting operations. 2.3.2 Public Interface Projects must provide suitable protection to public pedestrians and motor 29 vehicle users when vehicle movements into/out of and within the site are occurring. Projects must keep public walkways and roadways clean and free of construction-related hazards or materials at all times (except for cordoned-off areas). AECOM SHE Construction Guidelines (Physical Construction SHE Means and Methods) (S3EMIA-209-ATT2) Revision 0 June 8, 2016 Page 5 of 233 2.3.3 Public Health The project will employ effective environmental health measures in the 30 public interest to ensure dust, noise and vibration control measures are employed to meet legislative requirements. 2.4 Pedestrian and Vehicle Safety 2.4.1 Separate Access Separate site entrance/exit points for pedestrians and vehicles will be 31 established to keep them apart. 2.4.2 Pedestrian/Vehicle Physical and/or visible barriers (e.g. guard rails, traffic cones) should be 32 Segregation used to segregate pedestrians and vehicles along common access areas. Pedestrian crossing points must be provided across vehicle routes to access main work areas. 2.4.3 Hazard Notification Signs and/or lights, fences and barricades must be in place to inform 33 drivers and pedestrians of hazards and precautions. 2.4.4 Parking Parking areas for different kinds of vehicles, (e.g. delivery trucks kept 34 separate to private vehicles) must be created for the project. 2.4.5 Deliveries Delivery procedures and storage arrangements (including crane loading 35 areas) must be detailed and communicated. To avoid reversing risks a one-way traffic system should be used. Where unavoidable trained traffic signalers must be used to control vehicle movements in confined or congested areas.
