45 6 th May 2002 MS Thesis Presentation 45 Conclusion  Fourth Least Important Origin of Dissonances.

46 6 th May 2002 MS Thesis Presentation 46 Conclusion  Fifth Least Important Origin of Dissonances.

47 6 th May 2002 MS Thesis Presentation 47 Recommendations  First two Important origins can be diminished through “involvement of contractor in design phases”  Third & fourth most important dissonances origins can be handled through “Project management as individual professional service”  A neutral participant (Designer or Constructor) would be hired to bridge the schism between professional and working environment.

48 6 th May 2002 MS Thesis Presentation 48 Recommendations  Need of Establishing Numerous Professional Meetings during Project Phases.  Application of Construction Industry Model with necessary modification according to Saudi Arabian Construction Industry Requirements.  An Accrediting Body should be Established for surveillance in construction Industry Practices.

49 6 th May 2002 MS Thesis Presentation 49 Recommendations  Most Sophisticated & Updated Contemporary Professional Courses at institutions level.  Certification of Practicing Professionals on International Standards by Regional Certification Boards.

50 6 th May 2002 MS Thesis Presentation 50 Recommendations for Future Researchers  Design-construction interface in the context of Industrial projects and highways.  Considering the whole country’s construction industry as survey target.  Same survey considering the lower grade contractors and residential projects.
