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.
- Keeping school buildings weathertight
- What is weathertightness failure?
- Ministry’s approach to weathertightness remediation
- Getting the work done
- Remediation Strategy
We want all schools to have quality learning environments, and one of the Ministry’s priority work areas is to ensure that schools are safe and in good physical condition.
Work to keep buildings weathertight will normally be funded through a school’s Property Maintenance Grant or more significant projects scheduled as part of a school’s 5 Year Agreement (5YA).
For buildings either built or modified from 1994 onwards the Ministry’s remediation programme will address any occurrences of weathertightness failure. However, all buildings will be dealt with on a case by case basis.
If a school building is involved in a current legal claim, any specific queries can be emailed to the Ministry’s project manager for claims and assessments.
Weathertightness failure happens when water gets past the external cladding of a building. The failure is often a localised matter as a result of either workmanship and/or design issues, 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 general objectives in relation to weathertightness remediation are to:
- address all urgent health and safety issues as a priority,
- repair weathertightness failures and consequential damage,
- complete the work with the least disruption to schools as possible, and
- ensure all remediation work complies with the NZ Building Code.
Our approach includes an initial desktop exercise to review all existing information the Ministry has available. The information may include:
- advice from the school,
- previous building survey reports,
- information gathered during the annual school visits, and
- any other building condition assessments.
Once the existing information has been reviewed, the Ministry will usually organise a remediation inspection by an appropriately briefed Registered Building Surveyor.
The Remediation Inspection report is an important part of getting the work done. It's designed to accelerate the process of remediation and identifies the most effective solution for repair. Where weathertightness failures and consequential damage are found to be localised, this approach can help reduce potential disruption to the school.
The Ministry will provide technical support. This includes arranging for a registered building surveyor to:
- meet with the principal, caretaker or other staff members with knowledge of the weathertightness issues,
- review any previous survey reports,
- undertake onsite inspections, and
- identify the proposed remediation solution.
A 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:
- Remediation Inspection Report,
- Preliminary Design, and
- Detailed Design.
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.
