ABSTRACT
Despite some shortcomings, there is real benefit in the assessment of a design in terms of its potential life — it is how we establish this that matters, and once established, what is that value? Value in real net asset terms — value financially and value to society as a resource. The key areas affecting value are:
affirmation of the life as designed
quality matching design at completion
maintenance required
potential risk areas
potential at life end
accuracy of the business model.
