Construction Planning is the most important phase of the project. Planning regarding crew size, materials, equipments etc., should be done in the planning phase. Construction planners use Critical path Method & PERT analysis to reduce the duration of the project. As the duration of the project reduces, the cost of the project increases i.e. there is a Trade-off between Time & Cost. Using CPM the overall cost of the project can be reduced by using less expensive resources on Non-critical activities. It could be used by construction managers in a planning stage to explore numerous possible opportunities to the contractor and predict the effect of a decision on the construction to facilitate a preferred operating policy given different management objectives. The Study shows comparative results of the three techniques used to achieve Time-Cost Optimization. The two techniques used were Critical Path Method-Project Crashing Method, Linear Programming Method (LP). To compare the results a case study was considered i.e. construction of a Water Treatment Plant. Hence this paper presents: 1) Application of Project Crashing Method 2) Application of Linear Programming (LP)
