Environmental assessment includes the preliminary examination of the environmental impact of the project, in order to promote the perfect suitability of working with the environment. The socio-economic analysis, for your time, includes the investigation of the possible adverse effects of improvements and the performance of the work. This article is intended to present proposals for layout and analysis with presentations of technical allowances for decision making to promote reform and/or expansion of the cafeteria.
Inspect the condition of the building, there are some structural problems, with cracks and cracks in beams; electrical problems with wiring exposed and dry with long time of use. To meet the request of the public administration, technical analysis addressed the project for relocation of a restaurant and addressed the relevant situations. The facade is composed of reinforced concrete with structure independent of the main building, as shown in Figure 01 and 02.
Uniformity defect floor, indicating a possible junction box inside the restaurant environment, the wall covering is damaged and there are pipes and electrical boxes, shown in figures 13 and 14. Place the holder for work in the hot area of the restaurant and it should passed arrangements for laying electrical, hydraulic, sanitary and gas pipes. Drain channels installed between the outer wall and the facade structure, the corners of the support beams.
According to the Director's Control - SAD request, two layout proposals have been given for the possible placement of a restaurant in the building, please note that this is a DRAFT which is required for the development of more detailed projects and inquiries of DVISA for the entire project process. Another important issue is the change in the design of the facade by changing at least three frames to accommodate standard lighting and natural ventilation. One of the main pathologies found was cracks in the beams that broke in shear and indicated bending, as in Figures 49 and 59.
Another pathology found is due to oxidation of the steel pillars, according to figures 52, 55 and 56. Based on the registration of the structure, it is possible to keep an efficient control of routine inspection activities, schedule and record, as appropriate, repairs or reinforcements that may be needed during their lives (Sharma 1998, p. 234). It appears that, in order to ensure the safety of the regular guests of this possible cafeteria to be installed, not only property must be reformed for the electrical installations of the rooms that include the cafeteria, but also provision must be made for a reform in the sense lato sensu.
Local economy analysis: This technical note is true - if only for the problems and technical implications found in the dependencies. In the midst of analyzing the capacity of the current active main substation system to support new electrical loads, analyze two hypothetical situations. Thus, taking into account only the use of currently existing transformers, the analysis of the situation follows.
76 the consumer power factor must be verified for billing purposes by the distributor through continuous metering, thus mandatory for group A and optional for group B.
Such a need for analysis represents the fact that there is a need for a detailed study of the amount of electrical loads currently connected through the substation and thus determine the reserve capacity of the main substation. On this request and considering the third activation of the 500KVA transformer, it is certain that it will be necessary to invest in the Capacitor Bank installed, as shown below, in the main substation, the company responsible for the maintenance of preventive and corrective buildings of the building. to maintain at least the power factor value of 0.92. The analysis of the capacity of the transformers is carried out without prejudice to the analysis of the replacement of the feeders.
In this case, a priori it would not be appropriate for the Bank of capacitors located in the main substation. There is no way to specify the degree of integrity of the components and only a detailed study to determine the physical condition of all the component parts of this system. Recommendation: to guarantee the new installations, it is recommended that the new feeders, cables using the existing references directly from the main substation, meet the energy requirements that are created by the addition of new loads of electrical operation of the cafeteria.
It is required to set up all equipment and identify their consumption for the firing specification. Recommendation: in order to meet the standards for the installation of canteens and it is recommended to install the electrical installations, in order to facilitate the cleaning of the premises and to enable the aesthetic benefit. Recommendation: It is recommended that the following proportions be adopted for artificial lighting dimensions: Table - the recommended artificial lighting level for the cafe area is 150 W/6 m.
Project estimate AS BUILDING: after completion of the services, the project must be made as building of architectural and facilities (electrical, gas, hidrossanitário and fire fighting equipment and panic). Frames: to match the proposed layout provided for the exchange of some doors, but adjustment of the front frame. The transformer installed must meet the total active power of the equipment used, but due to the presence of reactive power, your capacity must be calculated based on the apparent power of the installations.
Another increase is related to the creation of more current circuits of the electric charges and their systems for the protection and control of equipment, which grows with the increase in reactive energy, increase in the capacity of TCs, TPS, etc. Similar to carrying the same active power, without the increase of the losses, the section of the conductors must increase when the power factor decreases. The investment in the expansion of the Bank of capacitors, to correct this power factor to the value determined by law, is not thrown.
Another question concerns the announcement of DVISA that closed the restaurant, the proposed adjustments in the preliminary draft, conforming to the requirements under the two plans proposed for the restaurant. The analysis of electrical implications is covered from the substation to the final circuits, and may eventually need an expansion of the Capacitor Bank.
