→   2 Cathedral Square, Spark NZ Christchurch New Build

The new Spark NZ office in the centre of Christchurch is a five-storey development including the basement. The development consists of offices for the Spark NZ, retail and office leases on multiple floors and a basement carpark. The seismic restraints for the mechanical services were coordinated with all the the other services, design by TMCo, during the seismic design stage. When the seismic design for electrical services have been completed by another engineering firm, Issei has been engaged to conduct both design review and construction monitoring for the electrical services. Although seismic installation was significantly affected due to slight changes on site, Issei ensured that all services are adequately restrained and code compliant during construction by communicating with contractors to suggest alternative solutions. Through the use of flexible and effective alternative solution suggested, Issei has ensured that the phased openings of the offices were on-time, safe and suitable for public use. Issei was the main point of contact for any queries around seismic installation for mechanical and electrical services. The experience at the Spark Issei will provide his expertise, experience and knowledge combined with the services coordination experience from other projects to ensure practicable, cost effect and code compliant installations are achieved on site.

→   Rolleston Library, Rolleston

The Rolleston Library is a project located in the centre of Rolleston and is part of the Rolleston Library and Community Centre development. Cable seismic bracing has been used extensively throughout the building to seismically restrain mechanical, electrical, hydraulic and civil services within the building. The use of cable bracing and their locations allow for flexibility on site for the contractors to easily coordinate the bracing angles. Due to the services being overlapped on the plan, Issei has used the 3D model of the services available to create detailed sections for areas where complex installations may occur. Since the services added significant gravity and seismic loads onto the structure, Issei has also communicated with the internal structural team to ensure that the structure supporting the services are able to withstand the loads. The seismically restrained services include compact HVAC components, ductwork, in-line equipment, floor mounted HVAC components, electrical cable trays, metal pipework and PVC pipework.
