Scaffolding for London Home Renovation Projects: A Complete Guide

SCAFFOLD FOR LONDON RESIDENTIAL PROJECTS FALLS INTO SEVERAL CATEGORIES, EACH SUITED TO DIFFERENT WORK TYPES AND ACCESS REQUIREMENTS:

INDEPENDENT TUBE-AND-FITTING SCAFFOLD (INDEPENDENT TIED SCAFFOLD): THE STANDARD SYSTEM FOR EXTERNAL ELEVATION WORK — POINTING, RENDER, ROOF REPAIRS, LOFT CONVERSION WORKS, PAINTING AND DECORATING, AND CHIMNEY WORK. CONSISTS OF TWO PARALLEL ROWS OF VERTICAL STANDARDS (UPRIGHT TUBES) CONNECTED BY HORIZONTAL LEDGERS AND TRANSOMS, WITH DECKED WORKING PLATFORMS. TIED TO THE BUILDING AT REGULAR INTERVALS (WALL TIES OR ANCHORS) — TYPICALLY EVERY 4M VERTICALLY AND 6M HORIZONTALLY. INDEPENDENT SCAFFOLD DOES NOT BEAR ON THE BUILDING — IT IS STRUCTURALLY SELF-SUPPORTING.

BIRDCAGE SCAFFOLD: A THREE-DIMENSIONAL SCAFFOLD THAT FILLS A SPACE — TYPICALLY USED FOR CEILING WORK, PAINTING HIGH VAULTED CEILINGS, INTERNAL DECORATING OF LARGE SPACES, OR WORK ON FLAT ROOF SURFACES WHERE AN ELEVATED WORKING PLATFORM IS NEEDED. EXPENSIVE IN MATERIAL TERMS (LARGE QUANTITY OF TUBE AND FITTINGS) BUT GIVES EXCELLENT ACCESS. RARELY USED IN STANDARD LONDON TERRACE REFURBISHMENTS.

ALUMINIUM TOWER SCAFFOLD: PROPRIETARY MODULAR TOWERS (HAKI, BOSS SOLO, INSTANT UPRIGHT) THAT PROVIDE A MOBILE WORKING PLATFORM UP TO APPROXIMATELY 12M WORKING HEIGHT (3:1 HEIGHT:BASE RATIO FOR INTERNAL USE; 3:1 FOR EXTERNAL). SUITABLE FOR: POINTING REPAIRS TO LOWER ELEVATIONS; GUTTERING REPLACEMENT; FASCIA AND SOFFIT WORK; AND SHORT-TERM ACCESS FOR INSPECTION. ADVANTAGES: MUCH FASTER AND CHEAPER TO ERECT THAN TUBE-AND-FITTING; MOBILE WITHOUT DISASSEMBLY (CASTORS ON BASE SECTIONS); NO LICENCE REQUIRED (USUALLY — SEE BELOW). DISADVANTAGES: WORKING DECK IS SMALLER THAN FULL INDEPENDENT SCAFFOLD; CANNOT ACHIEVE THE SAME HEIGHT AS FULL SCAFFOLD IN STABLE CONFIGURATION; NOT SUITABLE FOR HEAVY MATERIAL STORAGE.

ROOF SCAFFOLD (EDGE PROTECTION SYSTEMS): PROPRIETARY EDGE PROTECTION FOR PITCHED ROOF WORK — SYSTEMS SUCH AS LAYHER ALLROUND, HAKI STAIRWORK, AND COMBISAFE PERIMETER PROTECTION PROVIDE HANDRAILS AND TOE BOARDS AT EAVES LEVEL TO PREVENT FALLS. TYPICALLY COMBINED WITH INDEPENDENT SCAFFOLD AT EAVES LEVEL FOR LARGE ROOF PROJECTS.

SHRINK WRAP SCAFFOLD: INDEPENDENT SCAFFOLD FULLY WRAPPED IN HEAT-SHRUNK POLYETHYLENE (MONARFLEX, LAYHER LIGHTWEIGHT SHRINKWRAP) — CREATES A WEATHERPROOF ENVELOPE ALLOWING WORK TO CONTINUE IN RAIN AND PREVENTING DEBRIS FROM FALLING TO THE STREET OR NEIGHBOURS. USED FOR FLAT ROOF REPLACEMENTS, CHIMNEY REBUILDS, AND MAJOR EXTERNAL WORKS ON CONSERVATION AREA PROPERTIES WHERE DEBRIS PROTECTION IS REQUIRED. ADDS APPROXIMATELY 30-50% TO STANDARD SCAFFOLD COST.

SCAFFOLD IN PUBLIC SPACES IN LONDON REQUIRES LICENCES AND PERMITS. UNDERSTANDING THESE BEFORE PLANNING A PROJECT PREVENTS PROGRAMME DELAYS.

HIGHWAYS LICENCE (SCAFFOLD LICENCE): WHERE SCAFFOLD MUST STAND ON OR OVER A PUBLIC PAVEMENT OR ROAD, A HIGHWAYS LICENCE IS REQUIRED FROM THE RELEVANT LONDON BOROUGH COUNCIL. THIS APPLIES TO: - INDEPENDENT SCAFFOLD FOOTINGS ON THE PAVEMENT - SCAFFOLD OVER THE PAVEMENT (EVEN IF FOOTINGS ARE ON PRIVATE LAND) - ACCESS GATES AND BEAMS OVER THE PAVEMENT - HOARDING ON THE PAVEMENT EDGE

APPLICATION PROCESS: APPLICATION TO THE BOROUGH\'S HIGHWAYS DEPARTMENT — TYPICALLY 10 WORKING DAYS (2 WEEKS) MINIMUM NOTICE. SOME BOROUGHS (E.G. WESTMINSTER, CAMDEN, KENSINGTON AND CHELSEA) HAVE ADDITIONAL RESTRICTIONS AND LONGER LEAD TIMES. APPLICATION REQUIRES: SCAFFOLD DRAWING OR SKETCH; CONFIRMATION OF PUBLIC LIABILITY INSURANCE (MINIMUM £5 MILLION); AND PROPOSED DURATION. LICENCE FEE: TYPICALLY £100-500 DEPENDING ON BOROUGH AND DURATION.

SKIP PERMIT: IF SKIPS ARE PLACED ON THE PUBLIC HIGHWAY FOR DEBRIS REMOVAL, A SKIP PERMIT IS ALSO REQUIRED FROM THE BOROUGH — SEPARATE FROM THE SCAFFOLD LICENCE. COST: £30-100 DEPENDING ON BOROUGH AND DURATION.

SCAFFOLDING ON OR OVER NEIGHBOUR\'S LAND: WHERE A SCAFFOLD LEG, BOARD, OR TUBE MUST OVERHANG OR STAND ON AN ADJOINING OWNER\'S PROPERTY (COMMON IN LONDON TERRACE PROJECTS WHERE THE REAR SCAFFOLD MUST GO OVER A SHARED PARTY WALL OR NEIGHBOUR\'S GARDEN), THE PERMISSION OF THAT OWNER IS REQUIRED. THE ACCESS TO NEIGHBOURING LAND ACT 1992 ALLOWS A COURT TO ORDER ACCESS WHERE A NEIGHBOUR UNREASONABLY REFUSES — BUT IN PRACTICE, FORMAL REQUESTS AND WRITTEN CONSENT (WITH A FORMAL SCHEDULE OF CONDITION) ARE THE STANDARD APPROACH. DISPUTE OVER ACCESS CAN SIGNIFICANTLY DELAY A PROJECT.

WORKING HOURS ON PUBLIC SCAFFOLD: LONDON BOROUGH NOISE CONTROL RULES (CONTROL OF POLLUTION ACT 1974, SECTION 61 CONSENT) TYPICALLY RESTRICT NOISY EXTERNAL WORK TO MONDAY-FRIDAY 08:00-18:00 AND SATURDAY 08:00-13:00. SCAFFOLD ERECTION AND STRIKING IS NOISY — AGREE START AND END TIMES WITH THE SCAFFOLD CONTRACTOR AND INFORM NEIGHBOURS IN ADVANCE.

SCAFFOLD MOBILISATION (ERECT, ADAPT, STRIKE) IS A FIXED COST — THE MARGINAL COST OF KEEPING SCAFFOLD IN PLACE FOR AN ADDITIONAL 1-2 WEEKS IS SMALL (TYPICALLY £100-300/WEEK FOR HIRE). THE MAJOR COSTS ARE ERECTION AND STRIKING. THEREFORE:

COMBINE TRADES ON THE SAME SCAFFOLD: WHERE POSSIBLE, PLAN ALL EXTERNAL FACADE WORK THAT REQUIRES SCAFFOLD TO HAPPEN IN ONE CONTINUOUS PROGRAMME ON THE SAME SCAFFOLD. FOR EXAMPLE: ROOF REPAIR + POINTING + RENDER + CHIMNEY WORK + GUTTER REPLACEMENT + WINDOW PAINTING SHOULD ALL BE PLANNED WITHIN THE SAME SCAFFOLD HIRE PERIOD.

AVOID DOUBLE MOBILISATIONS: RE-ERECTING SCAFFOLD AFTER STRIKING IS THE MOST EXPENSIVE SCENARIO. IF THERE IS A CHANCE MORE WORK WILL BE NEEDED ON THE FACADE WITHIN 6-12 MONTHS (E.G. ADDITIONAL POINTING, CHIMNEY POINTING, OR DORMER WORK), INCLUDE IT IN THE CURRENT PROGRAMME.

ACCESS TO NEIGHBOUR\'S SCAFFOLD: WHERE A NEIGHBOUR IS ALREADY SCAFFOLDED, APPROACH THEM EARLY AND OFFER TO SHARE OR ACCESS THE SCAFFOLD (WITH APPROPRIATE LICENCES AND INSURANCE). THIS CAN SAVE £1,000-3,000 VERSUS ERECTING YOUR OWN SEPARATE SCAFFOLD.

SCAFFOLD INSPECTIONS: UNDER THE WORK AT HEIGHT REGULATIONS 2005, SCAFFOLDS MUST BE INSPECTED BY A COMPETENT PERSON BEFORE FIRST USE, AFTER ANY MODIFICATION, AFTER ADVERSE WEATHER, AND AT EVERY 7-DAY INTERVAL (FOR SCAFFOLDS ABOVE 2M). THE SCAFFOLD CONTRACTOR SHOULD PROVIDE A TG20:13 (BRITISH STANDARDS INSTITUTE) CONFORMITY CERTIFICATE AND HANDOVER REPORT. RETAIN ALL INSPECTION RECORDS.

SCAFFOLDING COSTS VARY SIGNIFICANTLY WITH: STRUCTURE HEIGHT AND AREA; SITE ACCESS CONSTRAINTS (NARROW ALLEYWAYS, SHARED GATED ACCESS); HIGHWAYS LICENCE REQUIREMENTS; DURATION; AND SCAFFOLD COMPANY RATES. THE FOLLOWING ARE TYPICAL LONDON MARKET RANGES:

ALUMINIUM TOWER SCAFFOLD (HIRE): - 3-5M WORKING HEIGHT TOWER (SINGLE BAY): £40-80/WEEK HIRE - 5-8M WORKING HEIGHT TOWER: £70-120/WEEK HIRE - DELIVERY, ASSEMBLY, AND COLLECTION: £200-400 ADDITIONAL

INDEPENDENT TUBE-AND-FITTING SCAFFOLD (TYPICAL LONDON TERRACE): - SINGLE ELEVATION SCAFFOLD, TWO-STOREY PROPERTY, ONE LIFT: - ERECT, 4-WEEK HIRE, STRIKE: £900-2,000 - SINGLE ELEVATION SCAFFOLD, THREE-STOREY VICTORIAN TERRACE, TWO LIFTS: - ERECT, 4-WEEK HIRE, STRIKE: £1,500-3,500 - FULL WRAP (ALL ELEVATIONS) ON A THREE-STOREY MID-TERRACE: - ERECT, 8-WEEK HIRE, STRIKE: £3,500-7,000

HIGHWAYS LICENCE ADMINISTRATION: £100-500 (BOROUGH FEE); SCAFFOLD COMPANY TYPICALLY HANDLES APPLICATION AND CHARGES £100-300 MANAGEMENT FEE.

SHRINK WRAP: 30-50% UPLIFT ON BASE SCAFFOLD COST.

EXTENDED HIRE: TYPICALLY £100-300/WEEK ADDITIONAL HIRE AFTER THE INITIAL CONTRACTED PERIOD.

INSPECTION: WEEKLY SCAFFOLD INSPECTIONS OFTEN INCLUDED IN CONTRACT — CONFIRM WITH SCAFFOLD CONTRACTOR.

HOW TO GET COMPETITIVE QUOTES: - PROVIDE CLEAR INFORMATION ON HEIGHT, ELEVATION LENGTH, AND DURATION - SPECIFY WHETHER PAVEMENT LICENCE WILL BE NEEDED - ASK FOR A FIXED-PRICE CONTRACT INCLUDING ERECT, HIRE FOR THE REQUIRED DURATION, AND STRIKE - THREE COMPETITIVE QUOTES MINIMUM — SCAFFOLD PRICING VARIES WIDELY IN LONDON - CHECK THAT THE SCAFFOLD COMPANY HAS: PUBLIC LIABILITY INSURANCE MINIMUM £5 MILLION; EMPLOYERS\' LIABILITY INSURANCE; AND CISRS (CONSTRUCTION INDUSTRY SCAFFOLDERS RECORD SCHEME) TRAINED OPERATIVES
