Several heuristics algorithms can be employed to solve single row layout in construction site planning. Firstly, this chapter builds Tabu Search to deal with the problem. Other heuristics methods which are genetic algorithm (GA) and estimation distribution algorithm (EDA) are also developed against Tabu Search. A comparative study is performed to test the effectiveness and efficiency of the algorithms. The statistical test, ANOVA followed by the t-test, compares the results of the three algorithms. Then, the pros and cons of using the algorithms are stated.

Rational construction site planning is especially important when building in cramped urban environments. This requires good training of qualified professionals. Currently, the system of higher professional education imposes new requirements on the technologies of vocational training. The introduction of interactive teaching methods and the improvement of the scientific, methodological and material and technical base are the most important stages on the way to the transition to a new level of education. This process is facilitated by practical exercises using electronic reference books and electronic simulators. As an example, the organization of the interactive form of a practical lesson "Designing temporary warehouses for a construction site" is considered. The lesson is part of the course for training specialists in the development of building master plans. The structure and organization of the lesson is described. It includes such forms of interactive teaching methods as mini-lecture, case-method, discussion. During the lesson, students actively participate in the discussion of the issues under consideration. They offer their own options for solving the tasks assigned to them. Consolidation of the acquired skills for calculating warehouse areas is carried out using an electronic simulator. The simulator allows you to optimize the required warehouse area. To do this, the simulator enters the initial data on the materials required for the construction of the facility. The ability to vary various parameters is provided. The simulator makes it easier to assimilate the studied material. The proposed simulator can also be used for practical purposes, for example, for rational planning of a construction site.

Construction site planning is an important task in a design team whereas a proper design of construction activities has a great influence in time and cost saving as well as in workers’ safety. Designers need to focus on site planning since the preliminary phase of building design in order to point out construction criticalities of the project that can affect execution phase. On the contrary, a scarce attention to operational issues during design phase is detectable in industry. Despite of the rapid diffusion of Building Information Modeling (BIM), a lack of BIM tools specifically studied for site design is detectable. Then the purpose of this paper is to describe a workflow developed with the aim to integrate site planning in a BIM design process, gaining thus operational advantages. The development of the workflow follows designers’ needs collected through the active participation of the authors in several design teams. A strong coordination and information sharing with other disciplines is the main task of the workflow, so that design choices can take into consideration operational issues as well. In order to simplify and accelerate the tasks of the site designer, the system is based on the use of some tools (such as databases of construction site elements and automatic checking tools), specifically developed for the purpose. The satisfaction of the designers involved demonstrates the efficiency of the system, in particular concerning the decrease of design time and the assistance of design choices thanks to operational information management.
