The implementation of any construction project is successful only when it is rational planning. At the stage of pre-construction preparation one of the main problems of planning are: the presence of order in the organization of pre-construction preparation, the presence of a modern design and the regulatory framework, the definition of the resource with the time factor, the definition of adequate duration and timing of the project. Selecting the most reliable method of determining the stage of pre-analysis, resource support of the construction process to a large extent affect the implementation of the project. In conditions of uncertainty are the most efficient flexible systems. The technique of construction and update of one of these systems is described in the article.
Keywords: planning, resources, the duration of the scheme, the model, the process

The quality of construction and installation works and applied materials, products and structures when erecting tall buildings are crucial in ensuring the reliability and durability of constructions and building comprehensive security as a whole. Buying a home and other structures in our country sometimes resembles a lottery: quality, regardless of the value of the object is not guaranteed. Moreover, the fact of putting the new State does not guarantee the quality of this object. Quality can be guaranteed only through incoming control processes at each stage of construction. Total quality control techniques can help in measuring, describing, analyzing, interpreting and modeling volatility of indicators of the quality of products, even with relatively limited amounts of data.
Keywords: quality control, strength, concrete, non-destructive method, analysis, durability
The sensor design on surface acoustic waves (SAW), representing the delay line with unidirectional inter-digital transducers (IDT) is considered. The factor of reflection of SAW from the unidirectional IDT loaded on impedance depending on value of resistance connected to it is investigated. On dependence of factor of reflection on size of resistance there is almost linear site at values of resistance more than 50 Ohm. The new design of the connected lattices of nanowire of zinc oxide, having the general resistance in a range of 50-250 Ohm which is connected to reflective IDT as loading is developed.

Analog-to-digital converter, with modulation, amplification and demodulation of the input signal is carried out. To compensate the additional error of voltage conversion, concerned with temperature instability, used dynamic cancellation technique, based on the correlation between offset voltage and modulator temperature fluctuation. ADC with response time 0.85 s performs the threshold of sensitivity 1 nV; 8,5 s - 0,31 nV, 85 s - 0.13 nV, 850 s - 0.1 nV, respectively, in the full-scale range 400 mV.
