Cathedral College Peer Review


Detailed peer review for WSP of the CLT structure and RSFJ connections devices for the Cathedral College building in Christchurch.
Detailed peer review for WSP of the CLT structure and RSFJ connections devices for the Cathedral College building in Christchurch.
The building, owned by Catholic Diocese of Christchurch, consists of CLT shear walls and CLT floors and a roof built with LVL rafter. The gross CLT floor area is 1500m2.
The RSFJ connection devices provide a resilient low damage
structure.
First building to use of innovative resilient slip friction joints (RSFJ) by Tectonus in a CLT shear wall building of this type.
This incorporated liaising closely with University of Auckland on reviewing this innovative structural solution.
A very restricted brown field site with three-dimensional co-ordination of the external services requiring construction sequencing and earthworks to be resolved during design.
Boundary retaining wall and basement construction through legal easements demanded proactive co-ordination with stakeholders to achieve a design.
Careful co-ordination was required with the QLDC street works development programme to resolve parking and line of sight issues.
Pumped sewage design was required to accommodate high flows.
Surface water was designed for retention and soakaway.
ENGCO were engaged by the contractor to design temporary sheet piling and support structures for site offices suspended over street footpaths.
