The information sought by the Deputy is not readily available in the format requested. There were over 120 primary schools completed from 2011 to date in 2016 and it would not be possible to calculate the average completion times by stage for that number of projects in the time available to answer this question.
The timeline for delivery of a primary school project is dependent on the delivery method selected e.g. RAPID design and build does not follow traditional stages of architectural planning but generally progresses from design start to completion of construction within 18 -24 months.
Projects which follow the traditional architectural planning model may be expected to complete design stages as follows:
Stage 1 – 3 to 6 months
Stage 2a – 4 to 7 months
Stage 2b – 5 to 10 months (add 5 months if a planning appeal arises)
Stage 3 – 5 to 6 months
Stage 4 - 12-24 months
Stage 5 – 12 to 18 months
However, these completion times are indicative only and can be expected to vary significantly from project to project depending on individual circumstances, including planning appeals, design issues, site issues and issues which can arise at tender and construction stages.
