Standards of Workmanship and Materials All materials, articles and/or workmanship are specified to be in accordance with the latest relevant British Standard Specification and/or British Standard Code of Practice, this is deemed to mean the latest issue of the British Standard Specification or British Standard Code of Practice together with any amendments. All works and materials shall comply with the latest British Standard or Euro Norm code currently in force at the time work is undertaken. “Make good” shall mean reinstate with materials and workmanship to match in every respect the surrounding work and property bonded thereto. All works are to be in accordance with BS 8221:Code of practice for cleaning and surface repair of buildings – Part 1: Cleaning of natural stone, brick, terracotta and concrete External render repair work should be carried out in accordance with BS 5262 Weather conditions If there is a risk of freezing of the building fabric, wet cleaning methods should be suspended, or suitable protection should be provided. Protection of buildings and surroundings  Protection and preliminary works requirements for the building should be provided prior to carrying out cleaning work.  Before cleaning, any fractures or open joints, including around windows, should be temporarily sealed to prevent entry of cleaning agents (non-staining, readily removable materials, such as foam rods, or temporary pointing, may be used).  Glazing and window frames should be protected with plastic and tape.  Electricity to external signs should be disconnected and external fittings (e.g. Signs and nameplates) should be removed and stored, or protected in situ.  Protection should be provided for street furniture, railings, signage, meters, vents, etc.  Decorative features (e.g. balustrades, cornices and carved ornamentation) should be protected.  Cleaning areas should be sheeted in. Other masonry materials should be protected within the cleaning area if applicable. Polished granite, limestone, marble, terracotta, and faience should be protected if chemicals are used to clean adjacent materials. Soft or brittle materials should be protected from adjacent abrasive cleaning.  All leaseholder plants, furniture and fittings shall be removed from the balcony areas, or temporarily protected.  The contractor should verify that all doors and windows shall be shut prior to commencing cleaning operations.  The contractor will be responsible for all claims for damage to leaseholder property arising from these works. Methodology  Cleaning should be from the upper parts of a structure downwards.  In cases where this is not possible, cleaning should be carried out in a manner that ensures finished work is not affected.  Temporary catchments and gutters should be provided, if required, to remove large amounts of water from the building and to avoid over-saturation at lower levels.  Gullies and other rain water discharge inlets should be protected from blockage through debris arising from cleaning and repair. Water washing  Before cleaning the exterior of a building, the building’s rainwater drainage system should be inspected to ensure that it is of sufficient capacity, and free from blockages.  An inspection of the masonry surface should be made. Temporary pointing or filling of any cracks that would let cleaning liquids enter the wall or the building should be carried out prior to cleaning.

If hot water pressure rinsing is carried out (i.e. with a minimum jet temperature of 80 ºC), it is essential to protect against damage caused by localized thermal stresses. Glass, plastics panels, windows, and paintwork should be protected. Hot water jets should not make contact with plastics frames, guttering, pipes, etc. Cast-off sheets should be installed to prevent unwanted saturation.

Clay brickwork  Water-based cleaning methods should be used to remove loosely adherent deposits only, with light brushing using a soft brush, if required.  Prewetting and rinsing, if required for a treatment, should be carried out with minimum wetting to minimize efflorescence caused by drawing salts to the surface of the brickwork.  Unless there is evidence to the contrary, bricks and joints should be assumed to be moderately to highly porous to chemical cleaner. Concentrated hydrofluoric acid-based cleaners should not be used and dwell times should be minimized.  Rinse water should not be applied at excessively high pressures, or through an unsuitable nozzle (e.g. a needle jet). Brushing  Brush fibres should not be of a material or hardness that could damage or stain the masonry surface.  Brushing should be carried out wet or dry using no more effort than is required to remove softened or loosely attached dry matter. Surfaces should be checked continuously to ensure no surface damage occurs. Brushing of surfaces should not cause hazardous types or levels of dust. Water cleaning  Large amounts of water are potentially hazardous to buildings and proper precautions and supervision should be provided so that water does not enter core material, internal iron, plaster, and wood.  A system should be established so that the minimum practicable amount of cleaning water is used, and that all potential water entry points are thoroughly sealed with sheet, tape, battens, or non-staining plugging material.  Temporary catchments and gutters should be provided, if required, to efficiently remove water from the building and to avoid over-saturation at lower levels. Stone Repairs  To be undertaken in accordance with the Technical Manual from United Kingdom Cast Stone Association and manufacturers recommendations. Render Repairs Render repairs to areas of fine cracking should be undertaken using Mendrend repair system, available from Rendit Ltd. Application should be by trained operatives strictly in accordance with the manufacturer’s guidance. A trial area shall be completed for approval by the Contract Administrator. Do not open up or hack back any render without first consulting the contract administrator.The render repair product is available from Rendit Ltd, Rear of Scope House, Doncaster Road, Barnby Dun, Doncaster, South Yorkshire, DN3 1HQ Tel: 01302 884385

Description

Health & Safety (designers risk assessment and pre-construction information)

A

The property is relatively modern and built after 1999, it is therefore considered unlikely that any asbestos containing materials will be incorporated and no asbestos surveys have been undertaken. All contractors staff should receive asbestos training as a matter of best practice.

B

The properties are relatively modern and therefore the risk of any lead based coatings is considered low. The contractor should take normal precautions relating to the dust created by any cleaning operations.

C

The buildings will be fully occupied during the works and the contractor should allow for liaison with residents and keeping them informed regarding progress. It should be appreciated that some of the flats are sub let and significant effort is expected in relation to coordination of the work to prevent damage due to water ingress through windows, vents etc. The contractor should allow for regular communication with Leaseholders and Sub-Tenants to arrange convenient times to undertake the works. The contractor should issue a letter to all residents with contact details for the site manager.

D

No information is available on the location or condition of the building services. The contractor should therefore assume that all cables and pipes are live and take appropriate precautions. Any external electrical services that are fixed to the wall should be protected if they will be subjected to excessive wetting, or at risk of being damaged by high pressure water/steam. Boiler flues, CCTV cameras, external lights, security alarm boxes, ventilation grills, air bricks etc should all be protected.

E

The site is close to the Basingstoke railway line. The work shall be undertaken to comply with all regulations relating to working close to railways. No access equipment should oversail the boundary with the railway.

F

The contractor shall ensure full compliance with The Control of Substances Hazardous to Health Regulation 2002 (COSHH). A risk assessment should be undertaken prior to usage of any cleaning chemicals. The minimum practical use of chemicals shall be made. All chemicals to be safely and securely stored and transported. The gentlest cleaner should be tried first on the facade (i.e., detergent before acids or alkalis), and the shortest dwell time should be used. No contaminated run-off shall be permitted to enter the drainage system.

G

The communal area staircases are the only fire escape for the upper floor flats and should not be obstructed during the works. All exit doors must be kept unobstructed.

H

The contractor shall prominently display warning signage in the areas where works are being undertaken. Where necessary pedestrian pathways should be blocked with hazard tape and appropriate diversions put in place.

I

The site contains a high number of young children and no tools or chemicals should be left unattended.

J

Parking around the site is extremely limited. The contractor should ensure staff do not park in the resident areas or obstruct the junctions. No large vehicles should be brought onto site without prior consultation with the Site Manager. Prior notice will be required before blocking access to any of the car parks. Note that there is limited vehicle access to the rear of the site.

K

The contractor shall meet with the onsite management team at the start and end of each day to confirm which blocks will be worked on.

L

Appropriate precautions shall be put in place to prevent trip hazards from electrical cables or water pipes where these are temporarily installed.

M

The height of the building makes water and chemical use hazardous, particularly in windy conditions. The contractor shall monitor the weather conditions and cease work if these become unsuitable for the proposed work.

N

The contractor shall take appropriate steps to limit the creation of dust.

O

Bird fouling deposits or dead pigeons should be sterilized prior to removal, or protective clothing and breathing equipment should be worn. Deposits should be wetted carefully so as not to disturb dust and sodium hydroxide-based degreasant applied with neutralization as appropriate. The deposits should then be removed with a scraper or by water rinsing. Hazardous waste should be collected and bagged for disposal by a licensed waste disposal agent. Rinsing water should not run into other parts of the building where it could deposit nutrients that could encourage biological growth.

P

All temporary connections to electric sockets should have RCD protection and be stepped down to 110V.

Q

It is important that elements are not over-wetted or subject to prolonged direct washing that may cause internal water ingress or damage to the building fabric (the render is particularly fragile and should not be "over" cleaned).

R

The contractor shall ensure all resident items on the balconies are protected, or relocated away from the work areas. It is particularly important to ensure that plants and other vulnerable items are protected. No plastic elements should be subject to direct washing with high temperature steam. Adequate protection is needed to windows and doors, in particular to prevent water ingress through trickle vents.

S

When working on the roof areas the contractor should either make use of the existing man-safe system, or should provide his own safe system of work, such as perimeter edge protection.

1.0

Access Methodology

1.1

The contractor shall supply all necessary temporary access facilities to safely undertake the works. A full method statement will be required as part of the tender submission. It is anticipated that work will be undertaken by a combination of elevated mobile platforms and scaffolds/towers. Any scaffolding must comply with BS EN 12811-1, BS 1139-2, BS EN 39, BS EN 1004, and BS 2482. Note that some of the ground around the perimeter of the site has a significant slope and is also saturated during rainfall due to blocked soakaways. Rough terrain platforms shall be used with appropriate spreader plates. Note that the perimeter of the site contains a number of drainage pipes and other buried services (exact locations unknown).

1.2

The Southern boundary of the site has a very steep embankment that makes access more difficult. The pricing schedule below (clause 5.0) provides two options for these elevations: Option 1: The contractor is to clean the full elevation, using an appropriate and safe access methodology (details to be provided with tender). It is anticipated this will require scaffolding. Option 2: The client will consider accepting a lessor standard of cleaning to the southern elevation that only involves cleaning those elements that can be reached from resident balconies or by locating hydraulic access platforms to the corners of the building. The contractor should set out what elements of the elevation will not be cleaned using this more limited access arrangement.

2.0

Pre-cleaning Activities

2.1

Trial cleaning areas The Emplyer will require the contractor to undertake a trial area of cleaning prior to commencing the main programme of work. The Employer will be under no obligation to continue with the work if the trial cleaning area is not completed to a satisfactory standard. A trial area should be cleaned to determine: a) the suitability of the cleaning method for the element, its condition, and the surface deposits; and b) the standard of cleaning that can be achieved, and its acceptability. Cleaning processes should be pretested on materials, surfaces and deposits representative of the whole building. If possible, test areas should be located in unobtrusive locations. Test areas should be small in case it is decided not to clean. When trialling different cleaning methods those which are least harmful should be tested first. Progression made towards methods which are more harmful should be made only if necessary in order to determine a cleaning method which is successful. A detailed record should be kept of trial cleaning and the location of trial areas. This should be retained for reference throughout the duration of the cleaning contract. The trial areas should be completed at least 48hrs before the main contract starts to allow the methodology for each area to be finalised. The CA's approval is required before continuing with the main programme of cleaning. The intention is that the cleaned elements should appear in similar condition to original construction.

2.2

2.3

Pre-Cleaning Repairs Any specified repair works shall be undertaken prior to the cleaning works to help prevent water ingress. The contractor shall provide the contract administrator with high level access to the entire site to determine any pre-cleaning repairs. Where necessary any vegetation that is growing up the building elevations should be cut back and removed to facilitate the cleaning works.
