K-INSTALL – SUPPLY & INSTALL SOLUTION FOR RESIDENTIAL DWELLINGS
K-Install provides the framework for the delivery of a consistent plasterboard supply and installation service for residential dwellings.
This manual sets out Knauf’s expectations in terms of delivering the service, with a particular focus on safety and quality outcomes. Satisfying these expectations is a fundamental requirement of achieving and maintaining Knauf “accredited installer” status.
5
SUPPLY & INSTALL SOLUTION
K-INSTALLSAFETY
The K-Install safety system is composed of several different elements. The basis of the Knauf accreditation system as it relates to safety revolves around setting the expectations, checking that those expectations are being met, and addressing issues where they arise. To maintain Knauf accreditation, subcontractors will be reviewed each year to ensure satisfactory performance.
INDUCTION
Having completed the training material, there is a questionnaire which must be completed in order to demonstrate an understanding of the requirements. A pass mark of 100% is required in order to successfully complete the Safety Induction.
Once successfully completed, there is a requirement to provide details such as your Construction Induction Card number and a recent photograph which will be included on the Knauf Accredited Installer Card.
SAFETY CHECKLIST
The Safety Checklist will be used by the contractors in observing behaviours of subcontractors on site. The checklist covers the main areas of risk on sites such as housekeeping, electrical safety, PPE, work methods and tools and equipment.
Non-conformances are to be addressed immediately with the relevant subcontractor, and a record of the checklist is to be maintained by the contractor.
ANNUAL REVIEW
Together with the contractors, Knauf will conduct an annual review of their subcontractor base to ensure the adequate performance of the subcontractor in relation to safety. Should the subcontractor not meet the performance expectations, their Knauf accreditation will not be renewed. If any subcontractors are in serious breach of safety requirements between annual reviews, their accreditation will be cancelled immediately.
6
K-INSTALL
OTHER SAFETY REQUIREMENTS
In addition to these accreditation measures, a number of different tools have been developed to assist contractors and subcontractors manage the safety risks associated with completing the work.
While the format and content of the templates used may be different, it is required that subcontractors have the following processes in place;
Site Risk Assessment
Used to identify the risks on each site, and the control measures to be put in place to manage the risks
A Site Risk Assessment should be completed prior to starting work, and again at any stage the conditions on site change
Stilts Risk Assessment
To be completed if stilts are going to be worn
Used to identify the risks specific to the use of stilts
The Stilts Risk Assessment should be completed prior to putting the stilts on and starting work
Job Safety Analysis (JSA) or Safe Work Method Statement(s) (SWMS)
These describe the way in which a task is carried out in the safest way possible
There is an example included in the appendices of this manual which can be used as a guide by subcontractors in developing their own or using the sample JSA/SWMS if it is confirmed by them as relevant to the task
Material Safety Data Sheets (MSDS)
Any hazardous substance or dangerous goods on site require a Safety Data Sheet to be accessible
All MSDS for Knauf manufactured products are available on the Knauf website www.knaufplasterboard.com.au/sds
7
SUPPLY & INSTALL SOLUTION
THE MINIMUM SITE SAFETY STANDARDS
It is expected that subcontractors adhere to the following site safety rules as a minimum:
Compliance with legislative requirements
All workers must have completed the K-Install accreditation program
All workers must have completed the builder’s induction program where relevant
All workers must have their Construction Induction Card on hand (or a photo of it)
All workers are to wear safety footwear, and any other relevant Personal Protective Equipment required to safely undertake the task or any other Personal Protective Equipment as required on the particular site
A Site Risk Assessment must be undertaken prior to commencing work. All workers must be familiar with the Risk Assessment (and sign it), and the Risk Assessment must be kept available on site
A JSA/SWMS should be completed for each task on site, and these must be available
All workers must be trained in the relevant JSA/SWMS
Workers must be adequately supervised at all times
A well-stocked first aid kit must be available on site
Tools and equipment should be in good working order and appropriate for the task at hand
All electrical leads must be tested and tagged, and in date
An MSDS should be available for all hazardous substances or dangerous goods on site
If a situation arises which poses an immediate risk, stop work and fix the issue or advise the site manager
Injuries or incidents to be reported to the Site Manager are as follows:
An injury which requires medical treatment beyond simple first aid (seeing a doctor)
A notifiable incident
Any incident where an inspector from a statutory body attends site
Any incident which may result in legal action
If a hazard arises which can’t be controlled8

K-INSTALL QUALITY
The K-Install Quality Induction works in much the same way as the K-Install Safety system. Both of the Safety and Quality Inductions must be successfully completed prior to the Knauf Accredited Installer Card being issued.
INDUCTION
Having completed the training material, there is a questionnaire which must be completed in order to demonstrate an understanding of the requirements. A pass mark of 100% is required in order to successfully complete the Quality Induction.
Once successfully completed, there is a requirement to provide details such as your Construction Induction Card number and a recent photograph which will be included on the Knauf Accredited Installer Card.
QUALITY CHECKLIST
The Quality Checklist will be used by the contractors in observing installation practices of subcontractors on site. The checklist covers the main areas of correct installation of plasterboard.
Non-conformances are to be addressed immediately with the relevant subcontractor, and a record of the checklist is to be maintained by the contractor.
ANNUAL REVIEW
Together with the contractors, Knauf will conduct an annual review of their subcontractor base to ensure the adequate performance of the subcontractor in relation to quality. Should the subcontractor not meet the performance expectations, their Knauf accreditation will not be renewed. If any subcontractors are in serious breach of quality requirements between annual reviews, their accreditation will be cancelled immediately.

K-INSTALL
OTHER QUALITY REQUIREMENTS
For the best possible quality of finish, it is important to make sure that the dwelling is plaster ready. That is, all of the basic requirements that should have been completed prior to installation of plasterboard have actually been completed. This also helps to reduce re-work at later stages of the build.
The Plaster Ready Assessment should be completed prior to commencing work. Any obvious issues should be brought to the attention of the Site Manager for rectification. The template in this manual is a guide to identify the important aspects to have right before starting work.
The contractor is responsible for ensuring the Plaster Ready Assessment is completed prior to commencement of the work, as well as completing the Quality Checklist during installation to ensure correct installation methods are being followed by the subcontractor.
Once all work is completed, the contractor should inspect the job and complete a Final Inspection Certificate to be issued to the builder.
OTHER RESOURCES TO ASSIST WITH QUALITY INSTALLATION
Subcontractors must be familiar with the Knauf guide which covers Plasterboard Installation Guide - Low Rise Residential Dwellings. A copy is available on the Knauf website www.knaufplasterboard.com.au/brochures-installation-guides. The Guide is available in English and Chinese. Aside from being familiar with the guide, subcontractors must ensure they install the plasterboard and associated products in line with the guide.
The Australian Standard which governs plasterboard installation is AS/NZS 2589:2017 – Gypsum Linings – Application and Finishing. All works must be completed in accordance with both the Australian Standard and the Knauf Installation Guide.
Having a standard builders specification is also a useful way to ensure the plasterboard and associated products are installed to the particular requirements of the builder. K-Install includes a template to assist with capturing this information. 11
SUPPLY & INSTALL SOLUTION
STANDARD PROCEDURES
To standardise the delivery of the supply and installation service, K-Install includes a standard set of procedures to describe how the service works.
The procedures cover;
Levels of finish
Timeframes prior to starting and timeframes on site
Calling a job up to start
Plaster ready and plaster start
Safety considerations
Pre-paint process
How to organise rectification work (maintenance)
How to organise credits and back charges
How to organise warranty works
KNAUF ACCREDITATION
As indicated earlier, in order to achieve Knauf accreditation, it is a requirement to successfully complete the K-Install Safety and Quality Induction Assessments.
Aside from the induction assessments, Knauf will also undertake a practical assessment of the subcontractor on site to observe the safety behaviour and quality of workmanship demonstrated. This will be done using the safety and quality checklists contained in the Appendices to this manual.

The safety induction forms part of the Knauf accreditation process
We want to ensure you are aware of the expectations around safety
It also aims to provide some practical tips to help you prevent injuries
It is the beginning of us working together, and a very important part of that is to understand that safety is non-negotiable.

K-INSTALLK-INSTALL
Compliance with legislative requirements
Ensure all work is conducted in a safe manner and is supervised
All workers are to have their construction induction card on them (or a photo of the card on their phone)
Other induction requirements have been met (e.g. builder induction, site specific induction)
All workers are to have been trained in the Safe Work Method Statement (SWMS) relevant to the work they are doing
There should be a stocked first aid kit on site and accessible
Personal Protective Equipment (PPE) is to be worn
Safety footwear (steel capped boots or shoes)
Other task appropriate PPE (e.g. dust masks for mixing or sweeping, gloves for handling metal). All task specific PPE should be noted on the SWMS
The purpose of the Site Risk Assessment is to identify any hazards that may present a risk of injury
Once a hazard has been identified, then something needs to be done about it to ensure it is fixed
All workers on site should sign off on the Site Risk Assessment prior to starting work so they are aware
If work cannot proceed safely, then do not start. Call the Site Manager to help resolve the issue
Each day, things on site may have changed. If they have, complete another Site Risk Assessment to see if there are any new hazards everyone needs to be aware of
There are no right or wrong answers on the Site Risk Assessment – it needs to reflect what is actually on site
GENERAL EXPECTATIONS
SITE RISK ASSESSMENTS
15
SAFETY INDUCTION
Traffic management refers to keeping machinery and people away from each other
This is especially the case on larger sites, but also when material deliveries are being made
When deliveries are being made, it is important that you keep out of the way of the truck as sometimes board or cornice may fall off the truck
A good reference guide is 'Move It – The GBMA Way' from the Gypsum Board Manufacturers of Australasia (GBMA)
Plasterboard should preferably be stacked horizontally on the floor
Sometimes due to space restrictions, it may be necessary to stack the board vertically against the frame.
TRAFFIC MANAGEMENT
STORAGE AND MOVEMENT OF PLASTERBOARD
It may be a good idea to use a spotter when reversing a vehicle to assist in the driver’s ability to notice obstructions and people
If there are traffic signs or rules on the site, these need to be observed
Councils are becoming more concerned about vehicles taking mud onto council roads – they are fining builders for this
The board should then be restrained properly. Be very careful when handling board from vertical stacks – if it falls on you, it could cause serious injury
Use correct manual handling techniques when cutting, lifting and carrying board
16
K-INSTALL
A Safe Work Method Statement (SWMS) is a description of how the task you are performing is safely carried out
It is your responsibility to have the relevant SWMS on site and available for everyone to refer to if required
All workers must be trained in the SWMS before carrying out the task
Messy work areas can lead to trips and falls, which may cause an injury
The safest way to work is to tidy up as you go
Before you start work, the site should be handed over to you in a tidy manner. If it isn’t, let the Site Manager know
You should sweep the site regularly during the day
SAFE WORK METHOD STATEMENTS
MAINTAINING A SAFE WORK AREA
If there are site specific requirements or hazards, these should be captured in a site specific SWMS
Knauf has developed a generic SWMS for you to adapt as may be needed
Keep doors and hallways clear of trip hazards
Store tools correctly (e.g. in a milk crate) and put them away properly at the end of each day
Ensure that any plasterboard stacked vertically against the frame is restrained at the end of each day or while not being used
17
SAFETY INDUCTION
Ensure the tools and equipment you have are the right ones for the task you are performing
Tools and equipment should be in good working order and well maintained. Check before you start work
Some of the tools used in plastering are sharp, and a number of injuries occur due to cuts on scrapers and Stanley knives. It is advisable to wear cut resistant gloves when handling scrapers or knives, as well as when handling metal products
Before connecting any power tool to the power supply, ensure there is a residual current device in place and that it is working
Domestic power boards and double adaptors are not allowed on site
Electrical leads are to be tested and tagged every 3 months as a minimum. All electrical leads on site must be tagged and in date
Where possible, keep electrical leads off the ground and out of water
TOOLS & EQUIPMENT
ELECTRICAL SAFETY
18
K-INSTALL
The risk of falling from a height on a housing site is real
Voids, stairwells, windows and balcony doors are just some examples of areas you could fall from
Ladders, steps, stilts and trestles will also likely be used in plastering, and you can fall from these too
It is important to ensure that all these potential risks are identified and controlled before you start working
Make sure you move trestles and ladders as required, and do not over stretch when you are on them – this could cause a loss of balance
If you move any part of the void protection (for example when passing sheets upstairs), it needs to be replaced immediately and not left open
Steps and ladders should be well maintained with treads regularly cleaned
Do not use milk crates or compound buckets instead of steps or ladders, as it is easy to lose balance on them
Use industrial grade ladders, not domestic ones
Do not stand on the top step or second top step of a ladder – read the warnings on the ladder
Do not over reach when on ladders
Ladders between floors should be secured at the top and bottom
Include safety precautions for the use of ladders in your SWMS
FALL PROTECTION
STEPS & LADDERS
19
SAFETY INDUCTION
If at all possible, avoid using stilts and look for alternate methods such as trestles or steps
You need to have undertaken the appropriate training in order to use stilts
Prior to starting work, you should complete a stilts risk assessment
You should check that the stilts are in good working order and well maintained
You should also check that the area you will be working in is appropriate for the use of stilts – there should be no trip hazards
Do not use stilts in stairwells or outside
To avoid over-balancing, do not over stretch and do not lift heavy or awkward items (and do not lift from below your feet)
A current Material Safety Data Sheet (MSDS) must be on hand for all hazardous substances or dangerous goods on site
The MSDSs for all of Knauf’s products are on the website
You should also ensure that you have an MSDS for any hazardous substances you bring on site, and store and handle them the correct way
Remember to use appropriate PPE when handling hazardous substances
USE OF STILTS
MATERIAL SAFETY DATA SHEETS

K-INSTALL
Some incidents must be notified to the relevant authorities
So that there is no doubt, report all incidents to your Site Manager when they are identified
The purpose of reporting incidents is so that we learn from them, and also to make sure you are okay. You will not get in trouble for reporting an incident
REPORTING OF INCIDENTS
Do a Site Risk Assessment at the start of work, and any time something on site changes
Have your Construction Induction Card on you (or a photo)
Everyone is to be trained in the SWMS for the tasks they are doing
Ensure there is a well stocked first aid kit on site
All electrical leads are to be tested and tagged every 3 months. They must be current
Wear the appropriate Personal Protective Equipment
Safety footwear (boots or shoes) Dust masks, gloves, safety
glasses when required
Keep your work area tidy as you go and avoid tripping hazards
Check that all equipment including ladders, trestles, stilts are in good working order before starting

Plasterboard must be kept dry and should be stacked clear of the floor using supports not more than 600mm apart as shown
Plasterboard must not be installed until the building is weather-proof
Condensation must not be allowed to form on plasterboard, otherwise this can lead to:
Joint distortion Mould growth Fastener popping Plasterboard becoming soft and sagging

QUALITY INDUCTION
Prior to installation of plasterboard, the frame must be suitable to allow installation according to the standard
This will help to ensure the best possible finish, and reduce costly and time consuming re-work later in the process
Some of the basics are;
Perimeter noggings installed in external ceilings and garage ceilings
Change of direction noggings installed in all required areas
Insulation installed correctly in ceilings and walls
Electrical rough in complete
Plumbing rough in complete
Box gutters/flashings installed where applicable and house water-tight
Bulkheads appear square and level
Any obvious framing issues have been fixed
Ceiling trusses appear level
LEVEL 3
A Level 3 Finish is recommended where no decoration is required such as walls above ceilings and concealed storage areas. The requirements for a Level 3 Finish are:
Framing requirements,
A bedding coat and second coat on all face layer joints and corners.
THINGS TO LOOK FOR TO ENSURE FRAME READY LEVELS OF FINISH
AUSTRALIAN STANDARD 2589:2017

K-INSTALL
LEVEL 4
Level 4 is the default finish and is recommended for most applications, when lighting is favourable and light tone, flat or low sheen paints are used. The requirements for a Level 4 Finish are:
Framing and back-blocking requirements,
Face layer joints finished using a Three Coat Jointing System,
A quality three coat paint system.
From section 3.1.4 of ASNZS 2589:2017 Level 4 shall be the default level for gypsum lining, unless specified otherwise.Flat or low sheen paints shall be used for this level 4.All joints and interior angles shall have tape embedded in jointing cement/jointing compound and a minimum of two separate coats of jointing cement/jointing compound applied over all joints, angles, fastener heads and accessories. All jointing cement/jointing compound shall be finished evenly and be free of tool marks and ridges in preparation for decoration.NOTES:1. In critical lighting conditions, surface
imperfections may still be apparent in aLevel 4 surface finish.
2. Where gloss, semi-gloss and deep tonepaints are used, surface imperfections will bemore evident.
LEVEL 5
Level 5 involves skim coating the entire wall or ceiling to provide an even surface texture.
The requirements for a Level 5 Finish are:
Framing requirements
Back-blocking of all ceiling joints and wall butt joints,
Joints finished using a Three Coat Jointing System,
Application of a skim coat over the entire surface to provide uniform texture and porosity,
A quality three coat paint system.

CEILINGSGENERAL REQUIREMENTS
Garage ceilings are subject to conditions that are more demanding than in other parts of the home. This is the case even when garages are located under the same roof as the rest of the home. Garages have large doors that when open let in rain and strong wind. Cars are garaged wet and they are not normally heated spaces. These factors call for a more durable installation to avoid future maintenance issues.
GARAGE CEILINGSGENERAL REQUIREMENTS

EXTERNAL CEILINGSGENERAL REQUIREMENTS
External ceilings include alfresco areas, carports, balconies and breezeways with plasterboard installed horizontally or sloping away from the main dwelling.
External ceilings are subjected to harsher conditions than internal ceilings, and therefore they need additional protection from the weather. This extra protection is designed to control the major causes of external ceiling faults.
MINIMUM CONDITIONS TO USE PLASTERBOARD IN EXTERNAL CEILINGS
The plasterboard must be designed for the appropriate loading conditions.
Cross ventilation above the cavity.
Condensation on the back and front of the lining must be controlled.
The plasterboard & compounds must not be subjected to direct water, high humidity, sea spray or dampness
The plasterboard and compounds must be installed after the roof covering has been installed and sealed.

STANDARD PROCEDURES FOR THE INSTALLATION OF PLASTERBOARD IN DOMESTIC DWELLINGS
71
AS/NZS 2589:2017 – Gypsum linings – Application and finishing
Victorian Building Authority's (VBA)Guide to Standards and Tolerances 2015
Knauf Plasterboard Installation Guide for Residential Buildings
Move it - the GBMA Way. A Guide to Safe Site Delivery of Plasterboard and Associated Products
Our standard level of finish is Level 4 as detailed in AS/NZS 2589:2017. To achieve a finish other than Level 4, this would need to be specified.
From the standard;
“Flat or low sheen paints shall be used for this Level 4.
All joints and interior angles shall have tape embedded in jointing cement/jointing compound and a minimum of two separate coats of jointing cement/jointing compound applied over all joints, angles, fastener heads and accessories. All jointing cement/jointing compound shall be finished evenly and be free of tool marks and ridges in preparation for decoration.
Notes:
1. In critical lighting conditions, surface imperfections may still be apparent in a Level 4 surface finish.
2. Where gloss, semi-gloss and deep tone paints are used, surface imperfections will be more evident.”

A further guide to Quality of Finish and Tolerances
Appendix E to AS/NZS2589:2017 provides a further guide for assessment of surface deviations and tolerances in evaluating whether or not joints, angles and fastener points in gypsum wall or ceiling linings have been finished to an acceptable standard. This covers recess edge joints, butt joints, external angles and internal corners. Some basic points:
1. For walls and ceilings measured over a 1.8m straight edge at any point, there is a tolerance of 4mm over 90% of the area, and 5mm over the remaining area.
2. A joint can be overbuilt by up to 2mm.
3. Joints are unacceptable if they show a distinct peak. The joint should be crowned.
4. An underbuilt or hollow joint is unacceptable.
5. When testing walls for adequate fixings, they should be pressed rather than banged. If there is movement between plasterboard and frame, additional screw fixings will be required.
6. Screw pops and mitre cracking up to 1mm are usually caused by frame movement and are not a plaster defect.
73
STANDARD PROCEDURES
The number of days to allow for the various processes are summarised in the table below. The days referred to are normal working days, and therefore do not take into account weekends or public holidays.
Call ups need to be made by 4pm to meet the above timeframes. If after 4pm, an additional day would be required.
For larger houses, there may be a requirement to extend the timeframe depending on the extent of works involved, but this would be a discussion at the beginning of the project. As a general guide, an allowance of 1 day per 100m² of plasterboard is required to complete installation.
STANDARD TIMEFRAMES
Process Number of working days
Call up for delivery and installation 5
Installation of single storey house 6
Installation of double storey house 10
Call up for pre-paint 5
Pre-paint works 5
Call up for maintenance work 5
Maintenance works Depends on scale
74
K-INSTALL
Call ups can be made by phone or email to the contractor, with email being preferred.
The delivery address and delivery date will be needed, and confirmation that the site is plasterboard ready (see next section for a description of what this means).
The installation start date would normally be the next working day after delivery, unless the job has been called up as a frame stage delivery.
Confirmation of the call up will be made by phone or email (or through your proprietary system if applicable).
HOW TO CALL UP A JOB FOR DELIVERY AND INSTALLATION
75
STANDARD PROCEDURES
A plasterboard ready site is one that has clear and unobstructed access. This means;
Externally
All rubbish is removed to allow a clear place for the truck to park and a clear pathway for the plasterboard to be carried
The truck parking location needs to be as close to the house as possible to enable passing of the plasterboard straight to the building
Any trenches are covered with suitable ramps
The walkway is clear and is not blocked by other tradespeople or equipment
Internally
Hallways are clear of rubbish and obstacles
The storage floor area is clear of any rubbish and obstacles
As far as possible, there are no other tradespeople working in the hallways and storage room area
A PLASTERBOARD READY SITE
76
K-INSTALL
It also means that plasterboard can be stored in a safe place where it is unlikely to be damaged. This typically means that;
The roof is installed
The building is water/weather proof
The floor area where the plasterboard is to be stored is clean, clear, dry and free of obstacles
Sites that are not plasterboard ready can increase the risk of injury and product damage.
If Risk Assessment performed by the delivery carrier indicates that the site is not 'plasterboard ready', the GBMA recommends that delivery of plasterboard not go ahead until a 'plasterboard ready' site can be confirmed.
Source: Move it the GBMA Way
77
STANDARD PROCEDURES
Before sending trades to site to install plasterboard, the contractor's Plastering Co-ordinator will make sure the job is ready to start. The Plastering Co-ordinator will check to see whether services (electrical and plumbing) are installed, whether insulation has been installed, and whether there are any other obvious issues which could delay installation of the plasterboard.
It is important that when the project is called up, the frame will provide a suitable substrate for the plaster work.
The site should be handed over to the Plasterers in a clean and tidy state - it should be swept out, and clear of other building materials which could cause trip hazards and the like.
Some examples of issues that can delay the plastering process are:
No access to water and power on site
Change of direction noggings not installed
Perimeter noggings not installed
Bowed or twisted studs
Protruding noggings
Steel angle braces not set in flush with the surface of the framing
Services not installed (e.g. plumbing, electrical)
Pipes or wires not correctly set back into the cavity
Excess insulation forced into cavity
Alfresco and garage not ready at the same time as the house for a single storey (and alfresco ready at the same time as the house for a double storey)
PLASTER START
78
K-INSTALL
There are some important safety considerations that need to be taken into account in the plastering process.
Stair void protection in a double storey house must remain in place throughout the plastering process
Kitchens and fix materials should not be delivered while plasterers are on site, as this creates a potential trip hazard
Where at all possible, other trades should not be on site at the same time as the plasterers. This sometimes has the potential of trades working above other trades, as well as their tools and materials being in the way of the other
If there is not enough room to stack plasterboard horizontally, it may be a requirement that the board is stacked vertically against the frame. This introduces a risk that the board could fall and cause injury, so the plasterboard must be correctly restrained.
SAFETY CONSIDERATIONS
79
STANDARD PROCEDURES
On a single storey dwelling, the pre-paint is carried out after the house has been fixed out and the kitchen cupboards have been installed.
On a double storey dwelling, the pre-paint is carried out after the house has been fixed out, kitchen installed and under stairs framed out. If the garage and porch were not ready with the main part of the house on a double storey, these areas should also be ready to be done at the same time as the pre-paint.
A call up for pre-paint is similar to the original delivery and installation call up - telephone or email through your requested pre-paint date to the contractor, and provide the site address.
The standard lead time for a pre-paint call up is 5 working days, and the standard time allocated for pre-paint work is generally 5 working days (depending on the extent of work required). The pre-paint process works as follows;
Day 1 - the house will be inspected to identify any areas which require rectification works and will be marked up to show those areas. This is preferably done with the contractor's Plastering Co-ordinator and the Site Manager together so that there is agreement as to the extent of work required
Day 2 to 4 - all items marked up during the pre-paint inspection will be fixed
Day 5 - the plasterers will return to complete the work and sand off any patches
Where rectification work is required as a result of other trades damaging the initial work, or as a result of frame issues, and depending on the extent of the work, it may be necessary to treat the rectification as maintenance work.
Once pre-paint work has been finished, the Painter should apply the first coat of paint. If minor plaster defects are identified after the first coat of paint, the painter should rectify. If the plaster defects are excessive or identified as a major issue, the painter should contact the Site Manager before applying any further coats of paint. The Site Manager would then contact the Plastering Co-ordinator to arrange rectification.
PRE-PAINT (FINISH OFF)
80
K-INSTALL
Maintenance work can be called up with 5 working days’ notice. The contractor will arrange to visit site and determine the extent of works required, and provide a timeframe and price to undertake the work.
The intention is that the rectification work is completed in one visit.
Where the Site Manager has reason to back-charge the contractor for damage caused or other identified reasons, the Site Manager should discuss the issue with the Plastering Co-ordinator and request the relevant reference number from the Plastering Co-ordinator. If the issue is not agreed, it should be escalated for resolution.
MAINTENANCE WORK
CREDITS/BACK CHARGES
81
STANDARD PROCEDURES
Where warranty issues are identified, an appointment needs to be made with the contractor to attend site and undertake an investigation as to the root cause of the issue. The contractor will liaise with the necessary parties in terms of determining the best way to resolve the issue.
