2-LEVEL CONSTRUCTION PLANNING MODEL WITH A LOCAL CASE STUDY

Two basic approaches underlie construction project management practices: Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT). CPM widely used in the construction industry is criticized for its lacks of planning of repetitive or linear construction projects that contain the same or similar number of units such as mass housing. In this paper, a new 2-level location-based planning model (2-LCPM) has been presented to be used in the planning of construction projects consisting of repetitive activities and which is thought to eliminate the deficiencies of the existing models. It was designed at two levels: globally and locally. It provides a schedule with minimum delay to the planner at the global level while provides resource continuity at the local level. 2-LCPM was programmed in Go language and tested with a real case study by using Postman platform and SQL database. As a result, 2-LCPM is presented a new plan with increased resource continuity which are 5.32 %, 3.645% and 2.455% respectively, besides gives the same project complete time which is 15 months.
