Partnerships for schools have a number of resources for schools including a collection of video case studies that can be accessed here: partnershipsforschools.org.uk/library/PE_dvd1.jsp
Attached are a number of publications that will also be useful in the context of BSF. Designing for Sport on School Sites is a good introduction to considering large scale investment in sport facilities and Active Design covers sport and PE design in its widest sense, including facilities beyond school.
