  36. Conclusion • Designers mostly categorized as design Consultants. • Majority of firms are Saudi National. • Professional experience range between 5-10yrs. • Working relationship between contractor and designer considered as “good relationship”. MS Thesis Presentation

  37. Conclusion(Most Important) • Top Most Important Origin of Dissonances. MS Thesis Presentation

  38. Conclusion(Most Important) • Second Most Important Origin of Dissonances. MS Thesis Presentation

  39. Conclusion • Third Most Important Origin of Dissonances. MS Thesis Presentation

  40. Conclusion • Fourth Most Important Origin of Dissonances. MS Thesis Presentation

  41. Conclusion • Fifth Most Important Origin of Dissonances. MS Thesis Presentation

  42. Conclusion (Least Important) • Top Least Important Origin of Dissonances. MS Thesis Presentation

  43. Conclusion • Second Least Important Origin of Dissonances. MS Thesis Presentation

  44. Conclusion • Third Least Important Origin of Dissonances. MS Thesis Presentation

  45. Conclusion • Fourth Least Important Origin of Dissonances. MS Thesis Presentation

  46. Conclusion • Fifth Least Important Origin of Dissonances. 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. 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. 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. 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.
