CRITICAL PATH SAMPLE PROBLEM: Given the following data for a certain construction determine the critical path, the total duration of the project in weeks. Nodes Activity 1-2 a. demolition and clearing 23 b. excavation 2-5 c. underground installations 3-4 d. foundations & columns 4-5 e. DUMMY 46 f. construction of second floor 4-7 g. roof framing and roofing 5-7 h. ground floorslab 58 i. Mechanical and elelctrical services 6 7 j. construction of exterior walls 7-8 k. DUMMY 7-9 1. construction of interior partitions 8-9 m. Mechanical and electrical fixtures 9-10 n painting and finishing Time (weeks) 8 14 6 5 0 6 6 4 12 12 0 10 12 8 Draw the project duration using the nodes and place the time in weeks, as can be seen a dummy activity is present for activity e and k which simply means you cannot go to e unless d is done first.
