ABSTRACT
The relevance of the considered the author of the theme is that during development of the project developer focuses on the optimization of financial indicators: Bank discount rate the interest cost on the value of the construction and subsequent delivery, such as for rent, but few says and examines optimizing space-planning decisions of the warehouse, engineering networks and constructions.
In this context, this article deals with the topic of the impact of the presence or absence of a mezzanine on the financial model of the project as a whole.
In the practice of designing and building modern warehouses building adopted Gables above the dokovymi zones (zones of loading and unloading). At the same time, never discusses how mezzanine affect: the cost of construction and financials.
Author, firstly, considers what mezzanines can be found in warehouses, secondly, on the example of one project is considering several options for the financial model of the project: mezzanine floor and without mezzanine:
1) Project budget:
- Purchase of land;
- Pre-project stage;
- Design stage;
- Construction costs;
- Costs for the Organization and management of the project;
- Reserve for unforeseen expenses.
2) Projected financial results of the project:
- Discount rate;
- Payback period-PB;
- Discounted payback period-the DPB;
- The average rate of return-ARR;
- Net income-cited NPV;
- Profitability index-PI;
- Internal rate of return-IRR;
- Modified internal rate of return-MIRR.
Research methodology is based on one project developer with the processing results by using AUTOCAD and the calculation of financial models using the Project Expert.
On the basis of the carried out researches the author makes the following findings:
1) Total construction cost of 1 sq.m. in stock without mezzanine is slightly higher. This can be explained by the fact that the relative cost, for example, the land remained the same as in option with a mezzanine, and reducing other costs not offset the decrease in the total area of the warehouse.
2) Despite the fact that the cost of construction of a warehouse without mezzanine is cheaper, but reducing the total area of the warehouse have not resulted in improved financial performance. Increased the payback period, though not significantly decreased net income shown in the reporting period.

ABSTRACT
The significance of the topic in question lies in the fact that during warehouse maintenance there arise such issues as increased equipment purchase costs, loss of productivity at loading and unloading operations and goods receipt and shipment, which can be connected to installation of a mezzanine above dock zones (loading/unloading, receipt and expedition zones). In this respect the article reveals influence of mezzanine on warehouse cargo handling and partially its influence on warehouse structural elements.
Practice of modern warehouse design and construction allows construction of a mezzanine above dock zones (loading / unloading zones). At the same time there appear two key questions – the installation height and the width of a mezzanine. However, the following issues are never considered: construction costs, warehouse structural elements and, which is
important, cargo handling processes, amount of weight-handling equipment, number of employees etc.
Taking warehouses of companies specializing in warehouse design and construction as examples, the author describes how a mezzanine together with a warehouse topology will influence cargo handling in a warehouse:
1) Types of structural mezzanine;
2) Height of mezzanine construction above the floor (mark 0,000);
3) Width of mezzanine construction;
4) Column space below a mezzanine;
5) Installation of dock equipment below a mezzanine, in particular, installation of sectional doors;
6) Cargo handling, amount of weight-handling equipment and number of employees in any variant of mezzanine construction;
7) Warehouse structural elements influence on variants of mezzanine construction.
Research methodology is based on the author’s study of space-planning decisions of warehouse complexes with the aid of AUTOCAD software and design of logistic operations map for each warehouse under consideration.
Based on the undertaken study the author makes the following conclusions:
1) Mezzanine height to the floor bottom is to be no less than 4.80m;
2) For optimal work space organization, it is necessary to use sectional doors with high lift with a mezzanine, or with vertical lift without a mezzanine;
3) For compact arrangement of stair flights, it is necessary to use four-flight stairs.
