Abstract
Construction projects in our country encounters some problems for contractors and owners before or during the projects. A lot of these problems are time problems leads to project deviation from the plans in term of time and cost. Time problems may occur at any time of project life. The main reason for these problems is at estimating productivity; this will lead to less or more project duration than what is proposed in the plan; and it confuses contractors and makes some problems with finishing on time. The productivity rate is very important for every management work to decide the best scheduling plan to improve it to decrease the time and cost. The project will discuss this problem and estimate the correct productivity rates for Palestinian labors and suggest some ways to increase and improve them. To attain the project scope, sufficient number of samples must be collected, so many construction sites have been visited and different samples were taken using two different methods, the first method is Survey method, and the other one is direct observational method. The results and findings will be summarized in a form of handout that can be used by construction contracts to increase their estimation accuracy in term of time and cost.
