Does that building time frame look even vaguely feasible peter?
You'd have to assume foundations would be put in place for a start any time next year, which would imply a much earlier start than July and if a consent is expected soon, there'd be a start soon with ground and foundation works and several months would be needed to get off-site manufacture made and ready for site.
There would be much else besides including hard landscape, services and fit-out. Other major contractors have said two years for a stand including fit out.
Seems to me it may not be worth the extra to rush for an opening mid to late season and some of the final linking in would be better done in a closed season. In that case, ready for 2016/2017.
This ties in with the Construction Press, which is quoting 'about 20 months' for the job.
