1. Scope of works

Pour, place and power-float finish a reinforced concrete ground-bearing slab for a domestic rear extension, using a concrete pump and delivery wagon. Site: 42 Beechwood Close, Bristol BS9 4P**. Contractor: Foundation & Groundworks Solutions Ltd (project ref FGS-2065). Client / principal contractor: Mr & Mrs Harding. The work is planned for one day (pour and finish) starting Tue 23 Jun 2026, with 4 operatives led by T. Whelan, Site Foreman (SSSTS, CPCS). The pump and wagon work from the domestic driveway and operatives reach the pour along a boarded route. Reinforcement mesh, spacers and DPM are checked in place before the pour and a curing membrane is applied after finishing. The work is done under a risk assessment under Regulation 3 of the Management of Health and Safety at Work Regulations 1999 and the duties in CDM 2015, with this method statement as the agreed way of working. Items to confirm before work starts: the full site postcode (shown as BS9 4P**); the weight of the pump and wagon and the ground bearing capacity of the driveway, to be confirmed with the pump and concrete suppliers and Mr & Mrs Harding at the pre-start walk; the location of drains, manholes and buried services under the driveway and pump position, and any overhead cables near the boom, confirmed by T. Whelan on the pre-start walk; whether the wagon can stand fully on the driveway or needs road space (if so, permission from the highway authority); the depth of the formwork and any drop at the slab edges; whether the power float is petrol or electric; the curing membrane product name and its Safety Data Sheet; where the wagon and pump will be washed out; and which other trades or residents will be on site on the day. T. Whelan confirms these with the pump supplier, the concrete supplier and Mr & Mrs Harding before the pour is booked.

2. Sequence of works

Method statement, safe system of work

  1. Pre-start walk the day before with the pump operator or supplier where possible: check driveway ground, drain covers, overhead cables, wagon and pump positions, route in and out, and agree the concrete delivery and pump set-up agreement with the client and suppliers
  2. Confirm the delivery time, volume and slump with the concrete supplier and check the pour area, shuttering, DPM, mesh, spacers and levels are complete and signed off before concrete is ordered
  3. Brief all 4 operatives on this RAMS, roles, the banksman, the exclusion zone, emergency arrangements and the stop-work rule. Everyone signs the briefing sheet
  4. Set up barriers and signage across the driveway and boundary, close off the pour area to residents, the public and other trades, and keep clear walkways to the house and welfare unit
  5. Lay and check boarded access routes to the pour, cap or cover any exposed reinforcement ends, and check shuttering is braced and secure
  6. Wagon arrives and is guided onto the driveway by the trained banksman. The driver and pump operator set out outriggers on spreader mats and check the boom is clear of overhead cables and people
  7. Pump operator sets up and secures the pipeline or hose, checks couplings and agrees hand signals and radio with the placing team
  8. Pump a small first load to prime the line. Operatives stay clear of the hose end until the flow is steady and the hose handler is in position
  9. Place the concrete in layers from the far end towards the wagon, with two operatives on the hose and two spreading, levelling and vibrating. Keep the hose controlled and never let it whip
  10. Use the poker vibrator on 110V supply to compact around mesh and edges, keeping cables off the wet slab and out of walkways
  11. Screed to level and close the surface. Operatives use kneeling boards and rotate tasks to limit time spent kneeling and on vibrating tools
  12. When the surface is ready, the trained operator power floats the slab, rotating tasks, with refuelling or charging done away from the slab and ventilation kept open if a petrol machine is used
  13. Clear the pump line by the pump operator's method with the area kept clear. Wash out the wagon chute and pump only at the agreed washout point, with no discharge to drains
  14. Apply the curing membrane as agreed and protect the surface from rain, frost, rapid drying and foot traffic. Leave barriers and warning signs in place around the slab
  15. Clean tools at the washout point, remove all waste, tidy boards and equipment, and check the driveway and pavement are clear of spillage
  16. Final check with the client, remove barriers once the area is safe, record the pour, and report any incident or near miss to T. Whelan

4. COSHH assessment

Built on COSHH 2002 regulations 6 and 7 and HSE guidance L5.

Check each entry against the supplier's Safety Data Sheet before work starts. Take workplace exposure limits from HSE EH40/2005.

Ready-mixed reinforced concrete (wet concrete)

Task or use
Pumped, placed, vibrated, screeded and power-floated into the ground-bearing slab
Route of exposure
Skin contact, eye contact and splashes. Inhalation of dust is possible from dry cement residues when cleaning up, and ingestion from contaminated hands.
Who could be harmed
The 4 operatives placing and finishing the concrete, and anyone close to the pour, harmed through skin burns, dermatitis or eye injury.
Hazards
Wet concrete is alkaline and can cause skin irritation, burns and dermatitis, and serious eye damage. Kneeling in wet concrete can cause burns. Cement dust can irritate the nose and throat. Check section 2 of the supplier's Safety Data Sheet for the exact hazards of the mix supplied.
Controls
  1. Eliminate hand contact by pumping the concrete and using tools such as rakes, screeds and floats rather than hands, and plan the work to reduce the amount of hand placing
  2. Choose a ready-mixed supply to avoid on-site mixing and cement dust, and ask the supplier about a lower-alkalinity or low-dust mix where practicable
  3. Engineering controls: use kneeling boards so no one kneels in the wet concrete, keep clean water and an eyewash station at the pour, and use the pump so fewer people handle the material
  4. Administrative controls: limit the number of people in the pour, keep others back, brief on skin and eye contact, wash skin immediately after contact and at breaks, change soaked clothing and boots, and rotate tasks
  5. Follow the Control of Substances Hazardous to Health Regulations (COSHH) 2002 and HSE guidance L5 (the COSHH Approved Code of Practice)
PPE
  • Waterproof, alkali-resistant gauntlet gloves, with specification from the Safety Data Sheet
  • Long sleeves, waterproof trousers and rubber boots that cover the trouser legs
  • Eye protection to BS EN 166 and a face shield for hose work
  • Disposable dust mask or RPE only if the Safety Data Sheet or the task requires it when handling dry cement residues
Storage and disposal
The concrete is delivered ready mixed and no bagged cement is stored on site. Leftover concrete goes to the supplier or is placed or allowed to harden in a designated area, and washings are collected at the washout point and disposed of through a licensed route, never to drains, in line with the Safety Data Sheet. Set concrete is disposed of as construction waste.
First aid and spillage
Skin: remove contaminated clothing and wash with plenty of clean water straight away, then seek medical advice if irritation or burns develop. Eyes: rinse with clean water for at least 10 minutes holding the eyelids open and get urgent medical help. Do not rub the eyes. Spills: contain with sand or boards, allow small spills to set or scoop up wet, and keep out of drains.
Health surveillance
Skin checks are expected for regular exposure to wet cement because of the risk of dermatitis. Operatives who have no signs of skin problems are checked by the foreman and by the employer's occupational health arrangements. This is a one day job, but anyone who reports skin problems should be referred.
Check against the Safety Data Sheet
Before work starts, get the supplier's Safety Data Sheet for the concrete mix and confirm the hazard statements in section 2, the PPE and glove specification, first aid measures, and spill and disposal advice. Check workplace exposure limits for dust in HSE EH40/2005.

Curing membrane

Task or use
Sprayed or applied onto the finished slab to control moisture loss during curing
Route of exposure
Inhalation of spray mist or vapour, skin contact, eye contact and ingestion from contaminated hands.
Who could be harmed
The operative applying the membrane and anyone close by or downwind, harmed through irritation of the skin, eyes and airways.
Hazards
The hazards depend on the product, which may be water-based or solvent-based. Check section 2 of the supplier's Safety Data Sheet for the health hazards and for fire risk.
Controls
  1. Substitute with a water-based, solvent-free or low-odour product where it will do the job, and confirm the product before work starts
  2. Apply by low-pressure spray or roller to limit mist, and apply outdoors where the air moves freely and the wind carries mist away from people
  3. Administrative controls: limit the quantity taken to the slab, keep others and the public away during application, keep containers closed, ban eating and smoking, and wash hands before breaks
  4. Follow the Control of Substances Hazardous to Health Regulations (COSHH) 2002 and HSE guidance L5 (the COSHH Approved Code of Practice)
PPE
  • Chemical-resistant gloves, with the type taken from the Safety Data Sheet
  • Eye protection to BS EN 166
  • Respiratory protection only if the Safety Data Sheet requires it, to the specification it gives, face-fit tested where tight-fitting
  • Overalls with long sleeves
Storage and disposal
Store in the original sealed, labelled containers in a secure, ventilated place away from heat and ignition sources, and out of reach of the public and children. Dispose of empty containers and unused product as the Safety Data Sheet advises, through a licensed waste route. Never pour to drains.
First aid and spillage
Skin: wash with soap and water. Eyes: rinse with clean water for at least 10 minutes and seek medical help. Inhalation: move into fresh air and seek medical help if unwell. Spills: contain with absorbent material, keep from drains, and dispose of the waste as the Safety Data Sheet advises.
Health surveillance
None is expected for a single short application, but this depends on the product, so check the Safety Data Sheet. Report any skin or breathing problems to the foreman.
Check against the Safety Data Sheet
Before work starts, get the Safety Data Sheet for the curing membrane product and confirm the hazard statements in section 2, flammability, the glove and respiratory protection specification, first aid, spillage and disposal advice. Check workplace exposure limits in HSE EH40/2005 if the product contains solvents.

8. Competence & training

All 4 operatives hold CSCS cards. One operator is power float trained and one is a trained banksman. T. Whelan, Site Foreman, holds SSSTS and CPCS and supervises the work. The pump operator and wagon driver are provided by the supplier and must be competent and hold the relevant training for their plant. Everyone attends the site briefing on this RAMS and signs it before work starts. Training for the specific plant, and any gaps, are to be confirmed by T. Whelan with the suppliers before the pour.

9. Permits

  • Concrete delivery / pump set-up agreement, agreed with the client and suppliers before the pour
  • No other permits are expected for this one day pour. If the wagon or pump needs space on the public highway, permission from the highway authority is needed first. To be confirmed by T. Whelan with the client at the pre-start walk

10. Access & egress

Pump and wagon use the domestic driveway, with a banksman controlling movements and entry onto and off the highway. Operatives reach the pour on a boarded, level route kept clear of hoses, cables and slurry. A separate, fenced route is kept for the client and others to reach the house. Emergency vehicles keep access to the driveway and street where possible.

11. Welfare

Site toilet and welfare unit on the driveway, with hand washing facilities, drinking water and a place to eat and rest. Clean water and eyewash at the pour for washing off concrete. Facilities are kept clean and operatives wash before eating, drinking and leaving site.

12. First aid

A trained first aider and a stocked first aid kit are on site, and the first aider is named at the briefing. Eyewash and clean water are at the pour for concrete splashes. Any injury or near miss is reported to T. Whelan and recorded in the accident book. Serious incidents are reported under RIDDOR where required.

13. Emergency procedures

In an emergency, stop the pump and all plant, make the area safe and call 999 if anyone is seriously hurt. Raise the alarm and keep the public and residents back. Meet at the agreed point on the pavement or in the client's front garden. Banksman and foreman check everyone is accounted for. For hose or pipeline failure or boom contact with overhead cables, keep everyone clear, do not touch the machine and wait for the supplier and emergency services. The address and nearest A&E details are given at the site briefing, and the full postcode is to be confirmed before work starts.

14. Environmental

Wash out the wagon chute, pump and tools only at the agreed washout point, with washings contained and disposed of through a licensed route, never to drains or soil. Keep concrete slurry off the road and pavement, and clean up spills straight away. Keep fuel for the power float in a sealed container with a spill tray. Take waste, packaging and offcuts away and recycle where possible. Keep noise and dust down and work only within agreed hours.
