Abstract
To streamline construction planning, one needs to assess and perform trial modeling of organizational and process-related factors impacting the final planned performance indicators. A proper calendar plan, one that would take due account of said factors, has a substantial impact on the efficiency and, sometimes, even the feasibility of a construction project as a whole. Therefore, the purpose of this paper’s research is to develop a method for determining optimum technical and economic parameters. A method should be considered legitimate which, given the labour intensity of the jobs assigned to a crew and the list of such jobs, makes it possible to determine the time said jobs will take to perform depending on the variation of the following factors: crew/unit numbers, job synchronization degree, job performance sequence, number of shifts and unit productivity. The authors have studied the algorithm and the method for the trial modeling of organizational and process-related factors when developing a calendar plan in order to identify qualitative time-specific and feasibility parameters. The paper reviews the example of how the optimum performance timelines for each crew can be determined.

The process of construction and installation work is the key part of implementing a construction project as a whole
The method for determining internal crew plans and the composition of integrate crews should be based on the following important requirement: the numbers and qualifications of crews should be picked allowing for the planned workload on those crews and rational organisation of their work. This requirement is necessary because the composition of a crew depends on the set of jobs it is assigned and the length of work on the number of units and the degree to which the jobs they do can coincide in time

Summary
The process of construction and installation work is the key part of implementing a construction project as a whole. This method widely used in the former Soviet republics to design the crew composition has a number of drawbacks resulting in a difference between actual and planned performance indicators. Such drawbacks include: In connection with this, the method for determining internal crew plans and the composition of integrate crews should be based on the following important requirement: the numbers and qualifications of crews should be picked allowing for the planned workload on those crews and rational organisation of their work. Productivity does improve when work flow is made more predictable, enabling a better match of available work load with capacity (labor hours)
