NETWORK ANALYSIS APPLIED TO PRECONSTRUCTION SCHEDULING OF A MULTI-PROJECT HIGHWAY PROGRAM

A PRACTICAL APPLICATION IS DESCRIBED OF PRECONSTRUCTION SCHEDULING THROUGH NETWORK ANALYSIS ON A MULTI-PROJECT HIGHWAY ADVANCE WORKS PROGRAM. THE APPLICATION IS CONFINED TO ABOUT 200 MAJOR PROJECTS UNDERTAKEN BY THE CENTRAL DESIGN GROUPS. THE OBJECTIVES OF THE SYSTEM ARE TO: (1) ACHIEVE COORDINATED ANALYSES OF PRECONSTRUCTION WORK ON ALL PROJECTS OF A WORKS PROGRAM, (2) ASSIST IN RATIONALIZING A WORKS PROGRAM BY PROVIDING A MEANS OF RAPID ANALYSIS OF THE IMPLICATIONS OF VARIOUS ALTERNATIVES OR OF IMPOSED CHANGES IN THE PROGRAM, AND (3) PROVIDE UP-TO-DATE SCHEDULES AND REPORTS TO ASSIST MANAGEMENT IN CONTROLLING THE EXISTING PROGRAM AT ANY TIME. THE SCHEDULING CONCEPT DEPENDS ON MAINTAINING CONTINUITY OF WORK FOR A FEW LEAD SKILL GROUPS RESOURCES OF SERVICE SECTIONS ARE CONSIDERED TO BE UNLIMITED AND SUBORDINATE TO THE SERVICE DEMANDS OF THE LEAD SKILLS. THE MAJOR AIM OF THE PROGRAM IS TO IMPROVE DECISION MAKING PROCESSES AT BOTH TOP AND LINE MANAGEMENT LEVELS BY THE FOLLOWING WAYS: (1) USE OF NETWORK ANALYSIS, (2) CONTINUAL REVISING NETWORKS TO TAKE ACCOUNT OF WORK DONE, CHANGES IN PLANS AND IMPROVEMENTS TO TIME ESTIMATES, AND (3) SIMULATION OF ALTERNATIVE PROGRAMS. THE SYSTEM HAS BEEN UNDER DEVELOPMENT FOR A LITTLE OVER ONE YEAR, WITH COMPUTER PROGRAM SUPPORT FOR THE LAST SIX MONTHS. SOME CONCLUSIONS ARE PRESENTED BASED ON THIS YEAR OF DEVELOPMENT.
