CIVIL DEFENCE ACTIVITIES

The issues under development on civil defense should be organically related to the specific conditions of the assignment for the course or diploma project and are aimed both at designing measures for the reliable protection of workers on the construction site from weapons of mass destruction, and at creating conditions for emergency recovery work and construction and installation work in wartime conditions.

The following questions can be assigned to the set of PG measures designed in the section of the construction plan:

- placement on the territory of the construction site of protective structures for workers with indication of routes to them;

- design of shelters using prefabricated reinforced concrete products stored at the construction site;

- assessment of the feasibility of installation in the basements of the erected building or construction of shelters for those working on the construction site - in case of a possible enemy attack (selection of the structural type and space-planning scheme);

- assessment of protective properties of inventory buildings against radioactive and chemical contamination and development of measures to improve them;

- Selection of inventory building types for use as an anti-radiation shelter at a certain level of radiation;

- dispersal and shelter of construction equipment on the site;

- design of standby water supply sources;

- design of emergency lighting.

Warehouses adapted for protective structures shall be equipped with transportation devices for loading, storage and unloading of materials.

Shelter should be located at the highest concentration of sheltered personnel. The collection radius of the sheltered should be taken in accordance with Annex 1 * SNiP II1177. Where groups of sheltered persons are outside the collection radius, provision should be made for them to be sheltered in a nearby shelter with a tambour lock at the entrance.

Shelters shall be protected against possible flooding by rain water as well as by other liquids in case of destruction of tanks located on the surface of the earth or on overlying floors of buildings and structures .

Shelters can be located at a distance of at least 5 m (in the light) from water supply, heat supply and pressure sewage lines with a diameter of up to 200 mm. With a diameter of more than 200 mm, the distance from the shelter to the water supply, heat supply and pressure sewage lines should be at least 15 m.

Environmental protection and natural resource management activities

Construction has a significant impact on the environment, air, water and biological resources.

Environmental measures in the design of the construction master plan should be carried out in the following main areas: reduction of air pollution, noise control, protection and rational use of water resources of land and soil, as well as protection of fauna.

The following special activities can be the most common and accessible in the construction plan section:

- setting clear dimensions and boundaries of the construction site; *

- Preservation of existing shrub vegetation and grass cover in the construction site area by performing, during the pre-construction period, a transfer for use elsewhere or here after completion of the main works;

- prohibition of the use of trees for suspension of electric cables, lighting fixtures and nailing of posters and signs;

- Rational placement of temporary buildings and structures, taking into account existing trees and shrubs;

- timely and high-quality arrangement of access and internal roads;

- exclusion of unorganized and disorderly movement of construction equipment and transport on the construction site bypassing existing roads;

- Elimination of open storage, loading and transport of dusty and low-strength materials by the use of containers or special vehicles;

- transportation and storage of commercial concretes and mortars in sealed containers;

- stop of internal combustion engines of mechanisms at their technological and organizational breaks;

- use of special tubular trays for garbage collection in buildings and structures;

- organization of mechanized filling of construction equipment and fuel and lubricants transport, as well as collection of spent oil for regeneration;

- reduction of sound strength at sound alarm;

- elimination of burying in the soil during planning and incineration of waste and remnants of construction materials at the construction site;

- completion of construction with high-quality cleaning and improvement of the territory with restoration of vegetation cover.

Development of quality management system.

1. Analysis of quality management systems in construction.

What is a competitive organization? This is an economic mechanism that operates to produce products, perform works or provide services with such quality and at a price that would satisfy various needs of society. Therefore, the quality of products, works and services is the main goal of the current economic mechanism of the organization and the main tool for combating the competitor. The increased competition in the world has led to a tightening of consumer requirements for product quality. A higher quality and the same price or the same quality and a lower price than a competitor is a formula for the competitiveness of an organization. Consumer requirements are included in regulatory documents. However, regulatory documents alone cannot be a guarantee of quality if the economic mechanism of the organization does not contain the relevant elements that ensure compliance with consumer requirements. The international practice of operating economic mechanisms in market conditions is laid down in the international standards ISO 9000, which are currently adopted in Russia as national ones. The standards were developed by drawing on existing international experience of organizations of various market economies and contain general requirements for the quality systems of organizations of various industries and economies. The presence in the organization of an appropriately certified quality system, created in accordance with the requirements of ISO 9000 standards, is the person of the organization, the guarantor of the quality of its products, works and services, testifies to the high level of the culture of building an economic mechanism within the organization, creates its international authority. It is with these organizations that consumers and investors want to deal with. It is such organizations that are competitive and survive in market conditions. The creation of a quality system in an organization is voluntary, but organizations are forced to create them and take the associated costs, since there is no other way in society that creates conditions for real competition. Over the past decade, the construction industry of our country has undergone tangible structural changes. They led to the emergence of a large number of construction and installation organizations that want to obtain licenses for the construction of various facilities, as well as orders from public, private and, including, foreign investors. This led to competition between these organizations, which makes it possible for investors to choose organizations that meet its requirements for the quality and cost of construction. At the same time, investors' requirements for the quality of construction significantly increased, which was more as a result of the separation of the functions of customers and contractors and the legislative consolidation in the "Civil Code of the Russian Federation" of the procedure for implementing contract relations in construction that meets the conditions of the market economy. Thus, there is a situation in which the creation of quality systems based on ISO 9000 standards in many construction and installation organizations becomes an extremely urgent task. However, the direct use of ISO 9000 standards for this purpose presents considerable difficulties, since they are general technical in nature and do not take into account the specifics of the construction industry organizations. This document contains specific methodological recommendations based on the provisions of ISO 9000 standards and interpreted in relation to the needs of construction and installation organizations (CMS). The recommendations are intended to assist the CMS management and engineering staff in the practical implementation of activities to establish and implement quality systems in their organizations that meet the requirements of ISO 9000 standards.At the same time, the management of the organizations should be aware of the need for an independent creative approach to the creation of quality systems to take into account the specific tasks, working conditions and structure of the organization in the developed documentation. Only with this approach will the established quality system be an effective means of leadership, management, ensuring and improving the quality of construction products, works and services, as well as the basis for improving the entire economic mechanism of the organization

2. Plan of development and implementation of quality management system in the organization.

2.1. Enterprise Quality Policy and Objectives:

• Enterprise objectives in the field of quality

- meet the requirements of design and regulatory documentation;

- satisfy the consumer's requirements;

- meet the requirements of the current legislation;

- Take into account environmental protection requirements;

- be economically profitable for the organization and offered to the consumer at competitive prices;

- perform all works within the scheduled time.

• Quality Organization Principles

The principle of a systematic approach is the need for quality management at all levels; Allocating quality management processes to all stages of the lifecycle Cover all management functions with respect to the managed object.

The principle of standardization indicates that all basic requirements for product quality and functions of an integrated quality management system must be regulated or provided by standards and regulatory and technical documentation.

The principle of an integrated solution provides an integrated approach to the problem of quality of final construction products, in particular, the allocation of tasks for managing the quality of intermediate and final construction products by levels of management (vertically and horizontally). And this in turn involves the development and implementation of a set of interconnected measures (technical, economic, legal, educational organizational, etc.) at all stages of the quality cycle of construction products.

The principle of rational limitation implies the constant implementation of the effect of filtering information to consider from the totality of only those phenomena, conditions and factors that most affect the quality of the final products of construction.

The principle of direct and feedback involves the constant interaction of the subject and the object in the management system at the stages: ("obtaining information" "critical assessment" "decision making and implementation," there is a connection between all elements of the integrated quality management system.

The principle of dynamism provides for a continuous process of improving the integrated quality management system during its operation, taking into account scientific and technological progress, changes in the requirements of regulatory and technical documentation and learning experience. The principle involves several stages of development of the system (from the most imperfect to automated at first at the industry, and then at the state level, considering it as an open system to be expanded as production and management develop.

The principle of optimality is to ensure that the tasks are achieved on the basis of the choice of the best option and at the minimum cost of developing the system and its operation.

The principle of integration and modular construction indicates that an integrated quality management system should consist of separate modules, which can be considered as independent systems operating at different levels of management and life cycle.

The principle of automation and new tasks focuses on automated problem solving based on the use of computer technology. To that end, it was necessary to formulate new strategies and methods for addressing them, taking into account the latest advances in science and technology.

• Main directions of quality system in the organization

- ensuring the established quality of construction and installation works at the stages of preparation of construction production and construction and installation works;
