Scaffolding 15 Golden Rules

1. Materials used to construct the scaffold must be in good condition. Boards should be clean and in good condition. Other materials, such as ropes, gin wheels and ladders, must be in sound, serviceable condition. All gin wheels must display the safe working load (SWL), gin wheels must

have a through inspection certificate within the last 12 months and all ropes require a thorough inspection certificate every 6 months.

2. The scaffold must be rigid, built of sound materials on good foundations and be secured to the structure using appropriate ties as per B G Solar scaffold drawings. Baseplates and soleboards are required under each upright on all fixed scaffolds.

3. The ground conditions on which the scaffold is constructed must be capable of carrying the weight of the scaffold plus the additional loading. The ground beneath sole boards must be level and properly compacted.4. To ensure stability of the scaffold (prevent movement either towards, away or side to side from

the structure) the scaffold must be tied to the structure, this may be via physical ties into the building or use of rakers (as per BG Solar drawings)

5. Working platforms must be close boarded and must be fitted with guard rails and toe-boards, including stop end boards. If materials are to be stacked on the platform above the height of the toe board, a suitable barrier (such as a brick guard) must be used to prevent the materials from falling. 6. The scaffold work platform must be erected as close as possible to underside of gutter/fascia board. Any gaps between inner board and structure must be kept as small as possible to prevent falls. Any gaps in excess off 225mm must have an inside scaffold board fitted7. Scaffolds erected in locations where it is likely to be exposed to severe weather conditions (high winds) must have the scaffold boards secured down to prevent dislodgement.

8. When undertaking work from either a sloping or flat roof type, if access is required within 3m of the roof edge (for example a gable end) the roof edge must be protected with edge

protection guard rails that is constructed of suitable strength, with toe boards to prevent objects falling to ground level. Ridge protection is to be installed where possible.

9. All work platforms must be provided with a safe means of access. Where extensive work is to be carried out and access is required to carry materials and equipment then the use of a stairway (Haki Staircase) for access should be provided. When ladders are to be used for access they must be secured properly (near to the top of the ladder and on the stiles not the rungs by either ladder clips or rope lashing single couplers are not acceptable) and be long enough to extend either 1m or 5 rungs above the work platform to provide a secure handhold. Ladders can be fitted inside the scaffolding but trap doors must be installed to prevent falls. Ladder access installed externally must have a self closing ladder/safety gate installed, which must open ‘inwards’ onto the platform.

10. If a gin wheel and rope is required, it must be securely attached to the scaffold as per the design drawing. The Gin wheel must display its SWL, and thorough inspection certificates must be seen. Gin wheel require thorogh inspection every 12 months and ropes every 6 months. If these certificates are not available then the gin wheel and ropes must not be used

11. Modular scaffolding must be dent free12. Overhead electric cables: Overhead power lines are normally un-insulated and can be lethal if contact, or near contact, is made. If overhead electric cables have been identified these must

be made safe before any scaffold is erected, generally this will be via protective sheathing. Proof

that it has been made safe must be obtained from the utilities company prior to erectionRev 5: January 2014




13. Falling objects/danger areas: The scaffold contractor must take all reasonable steps to prevent scaffold materials from falling off a scaffold while it is being constructed, altered or

dismantled. Physicals guards must be erected around the work area in which erection and dismantling is to take place to prevent unauthorised persons, including customers, from getting near to the

work area. Suitable signage must be displayed to warn persons of the work activities.14. Scaffold in public areas & Protection for BG Solar Customers: To reduce ‘contact hazards’ at lower levels, ie. head height, joints should be wrapped to prevent injury from sharp edges and plastic protective cups placed over the ends of scaffold tubes. Scaffold uprights should be wrapped in Hi—visibility warning tape. All access ladders must be securely boarded when the scaffold is left unattended. In public access areas ‘Heras’ fencing panels should be securely erected around scaffold perimeters to stop unauthorised access. 15. Inspection & Tagging Requirements of scaffolds: All scaffolding, including modular

scaffolding, must be inspected by a competent person employed by the scaffold company upon completion of erection. A scaffold Handover certificate must be issued by the scaffold contractor. A ‘Scaf-

Tag’ must be attached to the scaffold that has been correctly completed, signed and dated. The tag must be displayed at the access ladder location.

Every scaffold must be inspected prior to use, after any alteration, after any event which may have affected its stability, ie: after high winds. Scaffolds must be inspected at regular intervals and must not exceed seven days.

Scaffolds erected at 2m and above must have an inspection record entry recorded in an F91 or equivalent register

London & QuadrantLargest Social Housing Project in the UK

With 64,000 properties L&Q is one of the largest UK social landlords. British Gas fit 400 3.68Kw 16 panel Solar PV systems to 400 properties across multiple sites throughout the UK.

This is a testament to the logistical and large scale planning ability of British Gas. Completed between April 2011 and May 2012.

Working in partnership with British Gas, the installation of these panels will enable L&Q to claim the Feed-In tariff as well as selling surplus energy back into the grid. Savings were then reinvested into L&Q’s housing stock and resident services. The aim is to reduce carbon emissions by approx 600 tonnes each year for at least 25 years across the 400 properties.

British Gas installed a 4.1MWp ground mount array, the largest solar array, at the UK Plant of Toyota in Burnaston. The 16,800 panels will produce enough electricity annually to produce 7,000 cars. The system went from approval to commission in less than 3 months.

Along with the main array several showcase arrays were built including a 200kWp integrated glass wall showcase. The speed

and efficiency of British Gas meant that in less than 2 months; 4.5km of trenching done, 130,000 meters of DC cable laid, 6km of LV Cable laid, 3KM MV cable laid and 16,800 solar panels fitted

Developing workers and complying with strict British Gas health & safety rules made this one of our most successful commercial projects to date. It has give us the skills and knowledge to make these projects reality.

Southampton City CouncilCESP scheme and solar PV

As part of a CESP energy performance improvement project Southampton City Council engaged British Gas to install solar PV arrays on the roofs of five 16 storey tower blocks. With a potential Feed in Tariff deadline in early March 2012 the work had to be compressed into a 3 week installation timeframe.

British Gas Solar installed arrays of 35 kWp on the five tower block roofs, essentially in two weeks, including mounting frames on bespoke steel support posts. The electricity generated will feed the landlord supply of the blocks including communal lighting and lift power. The council will benefit from the feed in tariff for 25 years, and the electricity generated will save 78 tonnes CO2 per year.


Millennium Seed BankArchitecturally Sensitive Installation

Using black PV modules British Gas Solar installed 50 kWp across 6 of the barrel roof sections (2 rows). The system was commissioned prior to the December 2011 FiT deadline.

The Millennium Seed Bank at Wakehurst Place in West Sussex was first opened in 2000, and has a series of barrel roofs. In 2011 British Gas Solar was engaged to design and install a roof mounted solar PV system which would not detract from the architectural design of the building.


Marwell ZooCommitment to Sustainable Business Practices

With the December 2011 FiT deadline fast approaching Marwell appointed British Gas Solar to design and install two systems on animal enclosures at the zoo. These systems represent a leading commitment to Marwell’s commitment to sustainable business practices.

British Gas Solar installed and commissioned a total of 49.68kWp on the roofs of the Heart of Africa Building and the Okapi House in under 3 weeks ahead of 31st Dec 2012


Historical Royal Palaces

Three of Britain’s most iconic and best-loved palaces are getting a green makeover through a rigorous insulation project which will be installed by British Gas and Rockwool.

After these historic buildings, Hampton Court Palace, Kensington Palace’s Orangery and the Tower of London’s Queen’s House, have been properly insulated they will cut a combined £130,000 from their gas bills and reduce their CO2 emissions by 850 tonnes over the lifetime of the insulation.

In total, nearly 4500 square meters of the three palaces will be covered by insulation – the equivalent of 100 average semi-detached houses. 11,000 rolls of insulation will be required for the project which will take around 1000 hours to complete.

Hampton Court Palace, the former 16th Century residence of King Henry VIII, will be the focus for nearly 80% of the work with over 3,500 square meters of the palace, being insulated. The Queen’s House at the Tower of London, built in 1530 for Anne Boleyn (King Henry VIII’s second wife) and Queen Anne’s early 18th century Orangery at Kensington Palace will also feel the warmth of this initiative.
