construction and repair

Fall 2008 was not the best period for the construction of the country. Come difficult stage, which will verify the company's resilience to shocks and ability to work not only in the rapidly growing market, but also in terms falling demand. In this regard, practical interest in the measures taken by domestic producers to maintain business during the crisis and overcome its consequences. As the experience of a number of companies, even in difficult economic conditions, possible further development, if in time to adopt anti-crisis measures. Optimize costs in the first place you should think about reducing non-productive costs, particular ongoing administrative costs.

"We have revised the amount of compensation paid to employees on mobile communication and use of personal automobiles, travel and entertainment expenses, – says the director of personnel management company, "Christina Ignatowicz. A significant proportion of operating costs of companies linked to the rental office. Here a possible solution could be moved into the room smaller area or association sprawling administrative structures under one roof. "St. Petersburg is located not far from Moscow, so we decided to work on the projects in the capital. It is more profitable than include a separate office, – has explained the spokesperson of the Group pik Natalia Konovalova closure of the office "on the Neva." In many cases it is expedient to transfer some employees to work remotely mode. For example, planners, designers, IT-staff, accounting and certain other categories of employees may come into the office only when necessary.

Asphalt works – a process unit of pavement. Modern technologies allow asphalt to do better road surface than a few years ago. Now the company who orders roads Petersburg can even choose the color of asphalt pavement! The process of asphalt used everywhere. It is used in road construction, and patching of roads, and beautification Territories – asphalt playgrounds, parking lots, etc. Technology asphalt.

Asphalting is done by laying asphalt mixtures prepared base. The first stage clearance territory under the asphalting. Next on the cleared ground is laid foundation for future road or area. Thus the base can serve as a nonrigid foundation – otsevnye materials (crushed stone, gravel) and hard foundation – concrete. On the resulting base is laid asphalt concrete mix.

Asphalt concrete mix produced at manufacturing plants, or on site – from a strictly defined proportions of sand, gravel, mineral powder and bitumen. Then this mixture at 175 C delivered to the facility, where it is laying. As a rule, asphalting done in one or two layers. If you anticipate an increased load on the road, then placed 3-4 layers of asphalt mixtures. Laying blacktop carries asfaltobetonoukladchik. The last stage of compaction layers of asphalt produced rollers. Further, the surface is treated with bituminous asphalt emulsion. Asphalt mixture. Asphalt mixture is separated into crushed stone, gravel and sand. Further classification of mixtures is a function of temperature packing. According to this criterion asphalt mixture can be divided into hot and cold. Hot mix laid at not less than 120 C, cold – at or below 5 C. Hot asphalt can be divided into coarse, fine and sandy, depending on the the largest size of mineral grains. Cool the mixture can be divided into fine-grained and sandy. Depending on the porosity of asphalt concrete shall have the following split: – hot asphalt concrete: high-density, compact, porous, highly porous – cold asphalt have a residual porosity of 6% to 10% (GOST 9128-97). Further, gravel and gravel are divided into types: A, B, C, D and D. For more types of decoding gravel and gravel concretes can be found in gost 9128-97. Asphalting should be done in the dry warm weather. Work on the device cover must be completed 15 days before the autumn rains. The exception is the mixture with activated mineral materials. It should also be keep in mind that when installing a stacked layer asfaltobetonoukladchikom thickness must be greater than 15% than the design thickness. Asphalting of the road to hold area go to the technology under the force not to each company. Only qualified technicians can carry out road construction Petersburg, and these roads will last a long time.
