Unit Cost Method Estimation If the design technology for a facility has been specified, the project can be decomposed into elements at various levels of detail for the purpose of cost estimation. The unit cost for each element in the bill of quantities must be assessed in order to compute the total construction cost. This(…)

STRUCTURAL EVALUATION PROCESS
STRUCTURAL EVALUATION PROCESS This procedure is applicable for conventionally reinforced cast-in-place concrete, precast-prestressed concrete and post-tensioned cast-in-place concrete. The evaluation of an existing concrete building is usually performed for stability, strength, safety and future expected life. Evaluation of a structure may be required in the following situations: Structures are subjected to excess or improper loading,(…)
ESTIMATING PROJECT ACTIVITY DURATION
All formal scheduling procedures rely upon estimates of the durations of the various project activities as well as the definitions of the predecessor relationships among tasks. The variability of an activity’s duration may also be considered. Formally, the probability distribution of an activity’s duration as well as the expected or most likely duration may be used in scheduling. A probability distribution indicates the chance that a particular activity duration will occur. In advance of actually doing a particular task, we cannot be certain exactly how long the task will require.
