This guidance provides school boards and property professionals with the details of the Ministry’s weathertightness remediation programme. For buildings either built or modified primarily between 1994-2005, the programme will address any occurrences of weathertightness failure. However, all buildings will be dealt with on a case by case basis.
|Level of compliance||Main audience||Other|
This programme addresses state school buildings that have been subject to destructive testing reports, as part of the Ministry’s national survey of buildings with weathertightness issues – but are yet to have remedial work completed.

If you become aware of a weathertightness issue causing damage or an issue that may represent a health and safety concern, this situation should in the first instance be:
- addressed through your usual maintenance processes, or
- brought to the attention of the Ministry property advisor depending on the severity or urgency.
For buildings either built or modified between 1994 and 2005, the Ministry’s remediation programme will address any occurrences of weathertightness failure in such buildings. However, all buildings will be dealt with on a case by case basis.
Weathertightness failure happens when water gets past the external cladding of a building. The failure is often a localised matter such as:
- defective or missing flashings
- wall and roof cladding penetrations poorly formed
- inadequate clearance between the base of cladding and adjacent gardens or ground (paved or unpaved).
If left unaddressed, the resulting moisture levels can create further problems and lead to damage and possible health and safety risks.
The Ministry’s Weathertightness Remediation and Regulatory Strategy has key policies to help ensure that weathertightness issues won't arise from current and future remediation works. These are summarised as follows:
- All consultants engaged on the basis of competency and experience.
- Remediation Inspection Reports to provide evidence that the weathertightness failures identified are responsible for the observed damage.
- Documentation shall include sufficient specification, construction detailing and referencing of manufacturer’s technical literature for code compliant construction.
- Documentation will be subject to review, normally at two stages, Preliminary and Detailed Design.
- Contractors are to be selected on the basis of competency and experience.
- The consultants engaged to document the works are also required to undertake construction observation.
- Quality Assurance processes to be implemented so that the proposed and completed remedial works are code compliant and appropriate to the weathertightness failures and consequential damage.
- Completion documentation added to the Ministry’s property file.
For architects, designers, building surveyors and other property professionals involved with remediation, the full document can be accessed in the Toolbox below.
|General objectives in relation to weathertightness remediation||Which includes:
|Initial desktop exercise to review all existing information||As part of the approach, which may include:
Once the existing information has been reviewed, the Ministry will usually organise a remediation inspection by an appropriately briefed Registered Building Surveyor.
|Who is involved in the onsite inspection?||
|Purpose of the Remediation Inspection?||
Where weathertightness failures and consequential damage are found to be localised, this approach can help reduce potential disruption to the school.
Your property adviser will be able to advise you further on the process.
Where possible, the actual remediation work to address the weathertightness issues will be incorporated into your next 10 Year Property Plan (10YPP) in line with your 5YA budget cycle, or included in another capital work programme currently underway.
If the work is urgent or high risk it will be addressed as quickly as possible. The current 10YPP may need to be revised.
|The Ministry will provide technical support.||
This includes arranging for a registered building surveyor to:
|Weathertightness Review Panel (WRP)||Provides technical assistance around weathertightness remediation works and also undertakes independent reviews of project specific documentation at the following key stages:
Repair of the patches from previous destructive testing will be included within weathertightness remediation projects. Where previous invasive testing has been undertaken and the current outcome is that no weathertightness remediation is required, the Ministry will pay the full cost to repair the invasive testing and of the remediation inspection.
For buildings built or modified primarily from 1994 onwards and subject to weathertightness failure, the cost will be funded partly from your 5YA budget based on the following approach.
Fully owned Ministry Buildings
Buildings jointly owned between the Ministry and a board (or other third party ownership)
Wholly board owned property
For wholly board-owned property, the Ministry may provide technical assistance to boards with inspection and review process but does not contribute to meeting the associated costs. Note also that any defective school buildings with potential or current legal claims will be addressed on a case by case basis.
If you have exhausted your 5YA funding talk to your property advisor. There are existing processes in place to cover this kind of situation.
