Construction Scheduling Software - Q. Scheduling
Q. Scheduling software is a revolutionary construction scheduling software that has evolved in response to the widely recognized failure of the majority of construction contractors to fully use CPM or PERT, and adopt it as a basic construction scheduling technique, which suggested that there is some fundamental failure in the Critical Path Method and PERT network technique. This unwillingness flies in the face of a great deal of publicity promoting the use of Critical Path Method and PERT in construction scheduling. Such publicity has been supported by academic research which has failed to ask the basic question as to the feasibility of Critical Path Method or PERT for construction. If some contractors have to provide a Critical Path Method/PERT network in the bid at the request of the client, they usually employ an outside consultant to do it, pass his fee on to the client as part of the bid, and continue to manage the project in their own more appropriate manner. Therefore, it can be said that the construction industry has to a large extent rejected the Critical Path Method and PERT concepts, same as human bodies would reject medically transplanted organs from non related humans.
The low weighting on cost control and efficient use of resources in the concept of Critical Path Method and PERT resulted in a model that is not the best approximate model of the construction process. Q. Scheduling core concept is ensuring a continuation of work flow for each group of employed resources in order to minimize associated costs.
Q. Scheduling is quantitative scheduling in the context that quantities to be executed at different locations of the construction project form the elements of the schedule. Also Q. Scheduling is Queue Scheduling in the context that trades pass through the different segments of the project in a queue sequence. No interference between two activities is allowed at the same location. It is derived basically from the Line of balance technique with some modifications to allow for the non repetitive models that is characteristic of the majority of construction projects.
