New Approach to Improve General Contractor Crew’s Work Continuity in Repetitive Construction Projects

Preferences of Construction Managers Regarding the Quality and Optimization Criteria of Project Schedules

“…Sustainable schedules are not only about delivering results according to objectives (cost, time or resource consumption), but also include decisions that should be sustainable in the long term [2,3]. This is all the more difficult since the implementation of construction projects is a complex issue and is exposed to numerous risk factors, such as: dependence on the influence of weather conditions, individual nature of each construction site, real estate of construction products (during construction realization resources are transferred to the subsequent work stations as compared to an industrial plant, where the processed product is moved to subsequent workstations), significant scattering of structures in the field (scattering of objects in the field makes it difficult to organize works and increases the scope of transport works), late achievement of effects resulting from the construction of objects, significant dimensions and large mass of elements and construction objects, long period of use of construction objects, random nature of construction process realization time, internal and external supply problems, failure of machinery and equipment used [4][5][6][7][8]. These specific, complex conditions for the realization of construction projects significantly distinguish them from the realization of projects from other branches of the economy.…”

Crashing Construction Project Schedules by Relocating Resources

“…Tomczak and Jaśkowski put forward models that help improve the work continuity of the general contractor's inhouse crews, both in non-repetitive [10], [51], and repetitive projects [52]. Their MILP models assumed that subcontractors can be employed to help smooth the general contractor's resources, thus optimizing the use of in-house labor and improving the harmonization of works throughout the project.…”

Developing A Mathematical Model for Planning Repetitive Construction Projects By Using Support Vector Machine Technique

“…At the same time, the second category included repetitive projects because of their geometrical layout, such as tunnels, pipelines, highways, etc. [6]. Some authors stated that RCPs are characterised by a high degree of complexity in organisational and technological dependencies [7].…”

“…Network strategies customarily connected to construction planning prove inefficient within RCPs due to the expanded relationships among resources, locations (units), and processes [8]. RCPs often require crews to implement the same work in different units by moving from one unit to another inside the project [6]. Since this frequent resource movement, a successful plan is vital to guarantee the continuous utilisation of resources of repetitive exercises between units.…”
