Building security and control system have become necessary with increasing size and complexity of buildings. The building security and control system is designed to monitor and control mechanical and electrical installations, fire protection and escape, burglary, assault and emergency communication. In tall buildings and major complexes, the most important security requirement is fire-safety system. In(…)

Building technology provides information on building materials, construction materials, building guide, green buildings, high rise building, smart building materials, skyscraper, formwork, shuttering etc
REQUIREMENTS OF UNDERGROUND (BASEMENT) WALLS
Underground or basement walls are required to be constructed in case of underground water tank, basement parking, as a store room and many other purposes. These underground or basement walls are exposed to many types of loads and forces, moisture due to presence of ground water or due to rains etc. Underground walls must support(…)
TYPES OF BUILDING REPAIR & MAINTENANCE SERVICES
Building repairs and maintenance services mainly includes works undertaken for maintaining proper condition of buildings, its services and works in ordinary use. The use for which buildings are designed is the main factor in determining the required standard of maintenance. Excessive building maintenance should be avoided. At the same time, building maintenance should ensure safety(…)
BUILDING MAINTENANCE OBJECTIVE
Building maintenance is work undertaken to keep, restore or improve every part of a building, its services to a currently acceptable standard and to sustain the utility and value of the facility. The objectives of building maintenance is: (i) To preserve machinery, building and services, in good operating condition. (ii) To restore it back to(…)
ANALYSIS OF RATES FOR BUILDING WORKS
Analysis of rates for building works is the process of separation of works into components/elements (Viz. Labour, materials, machinery,transport, overheads and profit) of work and pricing them. Analysis of rates is required for: Insertion in a tender (i.e.) as a lump sum, item rates To check reasonability of rates inserted by tenderers To assess various(…)
FORMWORK– TECHNICAL, FUNCTIONAL & ECONOMIC REQUIREMENTS
Formwork is a temporary mould into which fresh concrete and reinforcement are placed to form a particular reinforced concrete element. A typical breakdown of total construction percentage costs shows that formwork material and labour alone consists of 35% of the total concrete construction cost. In the construction of a structural element, the cost distribution can(…)
MASONRY STRUCTURE DESIGN GUIDELINES
Masonry structures upto three storeys or maximum four storeys are not very uncommon in India. Most of housing boards, Development Authorities construct housing flats upto three/four storeys and masonry is definitely economical. National Building Code of India (SP-7) provides all the required design tables, nomograms and description on masonry design. Recommendations of IS 4326 for(…)
COMPRESSIVE STRENGTH OF BRICK MASONRY
Compressive Strength of Brick Masonry A wall or column carrying a compressive load behaves like any other strut, and its loadbearing capacity depends on the compressive strength of the materials, the cross-sectional area and the geometrical properties as expressed by the slenderness ratio (see Fig. 1). Fig. 1: Factors affecting the compressive strength of masonry(…)
