CCS were engaged by Maryville Retirement Village to relevel 21 villas over 7 stages of work at the Retirement Village. The solution provided by CCS required full Geo-technical assessment and reports as well as engineered design and sign off to enable the client to re-insure the earthquake damaged villas. The villas were constructed of concrete block walls & timber cladding, lightweight shingle roof and concrete slab on grade construction and adjoining villas are separated by a reinforced concrete block firewall.
The work was broken up into stages to allow the residents to continue living in the rest of the village giving only disruption to one stage at a time during the relevelling process.
The soil conditions varied across the site with Sand, Silts, Clay and Peat being found at different depths and zones. The water table was found at 1.5m BGL. The villas all had differential settlement across the Slab & ring foundation. CCS successfully lifted the units to bring them back within the target levels with a maximum lift of 218mm.
CCS provided the full package for the village including drawings/plans, council exemption, geotechnical report, engineering PS1 & PS4 for each stage. All villas in each stage were successfully relevelled with a variation in the level from the datum of a maximum of 44mm, which falls within the acceptable MBIE tolerances.
