C41 Repairing/ Renovating/ Conserving masonry GENERALLY / PREPARATION

101 APPROVED STONEMASONS or experienced brick

The work described in this section should be carried out by qualified stonemasons working for an approved stonemason subcontractor whose name shall be supplied to the CA for approval before putting the work to hand.

106 REMOVE COPING STONEWORK: REBUILD / REBED

This is to be carried out to all existing stones where indicated in the description of works. Mortar mixes to be agreed on site.

136 REMOVE FIXED ITEMS/REPAIR HOLE WITH LIME MORTAR

This is to be carried out where noted in the description of works.

140 RECORD OF WORK

• General: Record work carried out to masonry clearly and accurately using written descriptions, sketches, drawings and photographs, as necessary

• Specific records: Photograph areas to be treated and cross referenced to drawing. • Documentation: Submit on completion of the work.

- Number of sets: One. MORTAR REPAIRS GENERALLY

401 RAKE OUT LIME MORTAR JOINTS

Rake out well to a depth of 35mm using chisels or hacksaw blades of appropriate width so as not to damage existing. Flush out with water to ensure debris does not wash off and stain below.

406 CEMENT REMOVAL

Remove cement patch repairs. This is best achieved by continual gentle tapping with a hammer at the centre of the repair until the different mechanical properties between the brickwork and the cementitious mix causes the two to part without damage. The process is lengthy, and time should be allowed for it. Care is to be taken to avoid damage to the stone substrate, particularly where the repairs are deep and well adhered. Avoid damage to edges of surrounding stone. Remove cement pointing by using hand tools such as quirks or narrow chisels. Clean out joints using dry air sprays and nonferrous or stiff bristle brushes.

3.1.02 The works to be carried out are as stated on the drawings and/or described below. In the event of discrepancies, the drawings are to take precedence. The following items are to be separately priced but the tender sum will constitute an all-inclusive offer:

3.1.03 All discrepancies are to be notified to the CA as soon as they are discovered. The relevant clauses within this specification are to be sent to any subcontractor undertaking the works for them to ensure they price correctly. Missed items will have been deemed to be all inclusive within the price.

3.1.07 Due to the age of the properties (either built or refurbished circa 2003) asbestos was no longer allowed to be used within the UK construction industry. Whilst it is unlikely asbestos will be found within the buildings during these works, there is always the possibility (however slim) that there may be unknown asbestos in hidden locations which may become disturbed. If any material is discovered that may possibly contain asbestos, the material must not be disturbed in any way until the CA has been informed and it has been tested by a specialist. This must be organised by the Contractor in cooperation with the Contract Administrator, following the procedures laid down by FirstPort.

3.1.08 Due to the age of the buildings, it is unlikely that Lead will be present within the materials as elements were all stripped right back during refurbishment, the Contractor must however remain aware of paints and the like especially within the older blocks on site, which may have lead paint below the top surface.

To Collection £



£ p 3.1.09 It is to be assumed that the premises will be occupied in accordance with

the Preliminaries throughout the contract period. Access will be required at all times through the entrance doors & to fire escape doors. This is a residential estate & contractors are to be aware of this when considering works. Contractor will need to allow for suitable separation and protection for all work taking place.

3.1.10 Allow for protection of the building users from the building works. The Contractor is to allow for the protection of the ‘live’ areas. All debris is to be removed from site as it is produced in accordance with the hours stated in the preliminaries. It may be necessary to temporarily store materials on site pending suitable times for removal. There are the facilities for skips on site, however these must be more than 5m from a building.

3.1.11 Allow for the provision of adequate contract site safety signage visibly displayed or attached to working area to main entrance.

3.1.12 All items below are to be included but are not exclusive and the contractor is to allow for any other items he feels are necessary according to the drawings.

3.1.19 All loose and friable waste which may cause dust spread is to be double bagged before taking through common parts to the compound for removal from site.

3.1.20 It is recommended that this site is visited before pricing.

3.1.21 Where numerical amounts are stated, this is as a guide for the re-measurement of works on site. Where amounts differ, these will be added or omitted as required. the contractor should make his own measurements on site both for tendering purposes and also when ordering materials etc.

3.2.06 The contractor is to confirm the proposed access equipment to be utilised on site and associated costs herein. Should the method of access differ between elevations, then the type and cost of the proposed access will be clearly set out on an elevation by elevation basis and fully illustrated / detailed within the contractors tender return using separate costings sheets if necessary. The contractor must take into account the vehicle access routes on the site, particularly when working along the main thoroughfares such as the Boulevard.

3.2.10 All windows on the site are timber framed, the site is in a conservation area and as such care must be taken to prolong the life of the existing windows as long as possible. There are a combination of side hung casements and sliding sash windows across the various blocks. Allow for contacting each resident to ask them to leave their windows open on specific days. For this reason a residents liaison officer is recommended to be available on the site during the works. Please note that residents may forget to open windows and allowance must be made to miss windows and return to areas when the windows are able to be opened.

3.2.11 Where decorating windows – Satinwood - Apply 1 coat of Weathershield Quick Dry Undercoat (colour tba) with a brush and 2 full bodied satinwood coats (Brilliant White). Gloss - Apply 2 coats of Weathershield Quick Dry Undercoat (Colour tba at pre-contract meeting) with a brush and one full bodied gloss coat (Colour - Brilliant White). Paints as Section M60/126 by Dulux.. Paints as Section M60 by Dulux. The external faces and opening casement reveals are to be decorated, but not the internal faces. Colour of undercoat to be agreed at pre-contract meeting. All windows are to be decorated in the open position, allowed to dry, then shut at the end of each day. The site is not to be left completely unattended during the day as whilst the site is gated, there are undesirables who still manage to enter the site.

3.2.12 When preparing the metalwork to be painted, it is advised that a mini air sander (run off a small air compressor) is used e.g. 3M Roloc Disc Sander (which has the quick change Roloc pads). This equipment will produce a smooth finish quickly and get in between the railings easily. The finish required on the metalwork prior to it being decorated shall be to the standard produced by a mini air sander even if none is used. Note: electric drills or large grinders with sanding attachments do not produce an even finish. When using power tools googles shall be warn at all times.

3.2.13 Where repairs are requested below these are to be priced, however all repair works such as repointing or resin repairs to timber are to be agreed with the CA prior to being undertaken. Where it asks for a cost for Xsqm of repointing, should more or less be required, the figure submitted will be utilised as the agreed rate.

3.2.14 Where lime bloom/efflorescence is visible on the brickwork, these areas are to be brushed with a stiff brush/wire brush to remove as much as possible. The CA is to be on site to assess damage caused (much of the staining has come from the discharge of overflows and boiler flues). The boiler flue discharge is likely to be acidic and therefore may have etched the brickwork. These works are not to be undertaken in the wet and should be agreed on a block by block basis before starting.

3.18 General

Access 3.18.01 Provide all access equipment required to undertake these works.

Allow for protection of surfaces such as paving and provide spreader plates and door fans as required if utilising scaffolding. Ensure that any scaffolding which is erected to walkways and above entrances is accentuated and relevant warnings and protection against impact implemented.
