Main Contractor Registration of Interest for a Weathertightness Remediation project at Waitakere Primary School

Waitakere Primary School is located at 10 Bethells Road, Waitakere, Auckland and has a school role of approximately 500 students.
The school has weathertightness failures to 2 buildings that require repair, however this ROI only relates to Block 9, which is the larger of the 2 remediation projects. The design documents for block 2 are not complete but the successful shortlisted ROI tenderers will be invited to also tender for block 2.

NO SITE VISITS DURING THE ROI PROCESS

A summary of the main works (block 9) and separate block 2 project is listed below:

Block 9, was designed in 1998 and is a single storey, six classroom block built on timber pile foundations with a suspended timber floor. The key issues associated with Block 9 are:
a. Timber decay evident in areas of the structure which will require timber framing replacement and recladding.
b. Wall areas have insufficient clearance between the bottom plate and the ground which will require replacement
c. Roofing issues including structural support issues and insulation and ventilation which will require works to correct.
d. Area underneath the main building requires upgrading for fire regulation compliance.

• Block 2 is a two-classroom building (classrooms 18 and 19) with attached toilet facilities. It is estimated that this block was constructed circa 1997. The building is predominately direct-fixed fibre-cement sheet cladding with a small section of asbestos-cement sheet cladding on the toilet block.
A summary of the identified weathertightness items for building 2 are:
a. Inadequately fastened barge and ridge flashings to the main roof.
b. Inadequately sealed window jambs
c. Inadequately installation of roof to wall junctions
d. Inadequately cladding to ground clearance.
e. Moisture ingress has resulted in consequential decay damage to the wall and roof framing and isolated deterioration of the cladding.
A partial reclad is required with associated framing replacement.
