Q1) Why are building codes or standards essential for the modeling/ efficiency of drawings in Revit ?
ANSWER:
BUILDING CODES of standard modelling.
A model building code organisation is a set of building codes that are developed and maintained by a standard organisation. This standard organisation operates indenpently of the jurisdiction or area in which the building code standards are being developed. Local government or councils can be adopt these building codes as they see early, in order to better observation of construction within in area. Building codes organisation establish minium safety, construction and material requirements for builders to adhere it. To achieve the minimum standards of safety and welfare of residents of a building, the governing body defines a set of guidelines to regulate the construction activities termed as building codes. A building code is a set of rules to regulate the construction activities across the country.
NBC(NATIONAL BUILDING CODE of India) is a comprehensive building code, is a national instrument providing guidlines for the regulating the building constructions activities across the country. The It serves as a model code the adoptions by all agencies involved in builing constructions work be they Public Works Departments, other government construction departments, local bodies or private construction agencies. The code mainly contains administrative regulations, developments control rules and general bulding requirements: fire safety requirements: stipulations regarding materials, structural design and constructions (including safety): building and plumbing servies; approach to sustainbility: and asset and facility management.
Q2) From the National Building Code list the groups that will be essential to you when you begin modeling in Autodesk Revit.
ANSWER:
From the National Building Code list the groups that will be essential to you when you begin modeling in Autodesk Revit.
For the convenience of the users, this information is also in the following five groups of the
National Building code of th elndia 2005 each incorporating the related the parts/sections dealing with
particular area of building activity:
GROUP 1: For development, building planning and related aspects.
GROUP 2: For structural Design and Relatd aspects.
GROUP 3: For Constructions Related Aspects including Safety.
GROUP 4: For aspects Relating to Building Servies
GROUP 5: For Aspects Relating to plumbing Services including Solid Waste Management.
OR
GROUP A-RESIDENTIAL
GROUP B-EDUCATIONAL
GROUP C-INSTITUTIONAL
GROUP D ASSEMBLY
GROUPE -BUSINESS
GROUP F-MERCANTILE
GROUP G-INDUSTRIAL
GROUP H-STORAGE
GROUP I- HAZARDOUS
dealing in the respective areas.
The Code, besides prescribing the various provisions, also allow freedom of action to adopt appropriate practices and provides for building planning, designing and construction for absorbing traditional practices as well as latest developments in knowldege in the various discplines as relevant to a building including computer aided and/ or other modern sensor aided activites in the various stage of conceptualization. planning, designing, construction, maintaining and repairing the buildings. India being a large country with substanial variations from region to region, this code has endeavoured to meet the requirements of different regions of the country, geographical terrian. proneness to natural diasters, ecologically appropriate practices use of eco-friendly materials reduction of pollution, protection and improvement of local environment and also socio-economic consideration towards the creations of sustainable human settlements.

Q6) Distinguish the roles of Design team and Management team.
ANSWER:
DESIGN TEAM:
In building projects various aspects like form; space planning Aesthestics:fire and life safety: Structural adequancy: Plumbing services: Lighting and natural ventilation; electrical and alied installation; air conditioning, heting and mechanical ventilations, acoustics, sound insulation and noise control; installation of lifts and escalators: building automation; data and voice communication: other utility services installations, Landscape planning and design, urban planning, etc need to be kept in view right at the concept stage.
The project requiring such multi-displinary inputs needs to becoordinate approach among the professional for proper integration of various design inputs. For this, and to take care of the complexities of mutiti-displinary requirements a design team professionals from required disciplines shall be constituted at the appropriate stage. Here, it is desirable that the multi disciplinary integration is initiated right from the concept stage. The Team shall depend on the nature and magnitude of the projects
Design is an evolutionary and practicipatory process Where participation of owner constitutes a very important input at all stages and all same shall be ensurd by the design team.
To ensure proper implementation of the desing the design team may be associated during the
construction/-execution-stage
MANAGEMENT TEAM
The objective of project management of construction management is primarily to achieve accomplishment of project indicand, with the designs and specifications in a stipulated time and cost framework with degrou of assurance prior to commencement and satulation on accomplishment.
For large projects, Seperate teams of experienced professionals from the required disciplines may be constituted for project management and for construction management depending upon the complexities of the project. However, for smaller projects these teams may be combined. The teams shall be responsible for day-to-day execution, supervision, quality control, etc and shall ensure inter-disciplinary co-ordinate during the construction stage. The team shall be responsible to achieve satisfactory complexion of the project management team associated actively during the project execution stage.
