  • Abstract:
  • Constraints are encountered in every working environment whether it may be manufacturing industry, supply chain, construction industry etc. Construction companies are time bound endeavours meant to be realized within stipulated time. They have a particular goal to be achieved in time but constraints in the project create imbalance of sources and form barrier in completion of the project. Theory of constraints has application in manufacturing, project management, marketing and sales, finance and accounting, supply chain distribution. Critical chain project management (CCPM) is utilized in project management. CCPM uses schedule network analysis technique. It focuses on those activities having longest chain. Buffers are used throughtout the TOC. Buffers are placed before the governing constraints, to ensure that the constraint is never starved. Buffer are placed behind the constraint to prevent downstream failure from blocking the constraints output. This concept of identifying the constraints and eliminating by using CCPM scheduling will be conducted on selected projects. First and foremost, field study and questionnaire survey is conducted for collection of basic information and to study current situation of the constraints in today’s construction industry.
