Conditions & environment for setting up / developing routes / pathways:
Knowledge - technology transfer Education and training (necessary for technology transfer - currently
inadequate?) Market pull (new products envisaged) Venture capital, public funding
(medium-long period of return)

ROADMAP: an overall map is not practicable charts are constructed
Specimen charts such as for a specific construction sector (buildings) or construction materials are developed, estimating progress from current bases to aims / destinations over a 25yr period
Similar charts can be established for sub-sectors in more detail or for other criteria, even across the charts presented

f CONCLUSIONS:CONCLUSIONS:
The Roadmap Charts reflect current situation / predictions: periodic updates are therefore recommended
Accuracy of the predictions is limited by fragmentation of current RTD and its uneven progress

f CONCLUSIONS:CONCLUSIONS: Progress will be accelerated if research were integrated Existing SME’s, forming the bulk of construction
industry are poorly suited as vehicles for progress in exploitation of nanotechnology
Ecological, environmental and health & safety impacts of nanotechnology will have to be constantly monitored and applicable regulations and legislation amended and/or developed
