Introduction to National Building Code and Steps in a Construction project

Q1) Why are building codes or standards essential for the modeling/ efficiency of drawings in Revit ?

 

ANS) A set of standard that are uniform to all structure 

         It protects the construction safety 

         Modern construction method

         Provides building standard 

 

             A building code is set of rile to regulate the construction activities across the country.

             NBC is a comprehensive building, code is a national instrument 

             providing guidline for the regulating building construction activity across the country 

             it serves as model code the adoption by all agencies involved in building construction work be they 

             the code mainly contain administrative regulations, development control rules and general building requirement, fire safety requirement, stipulation regarding materials, 

 

 

Q2) From the National Building Code list the groups that will be essential to you when you begin modeling in Autodesk Revit

 

ANS) Group A: Residential Building 

         Group B: Educational Building 

         Group C: Assembly Building 

         Group D: Institutionl Building 

         Group E: Murcantile Building 

         Group F: Business Building 

         Group G: Storage Building 

         Group H: Industrial Building 

         Group J: Hazardous Building 

 

             the code, beside prescribing the variopus provision ,also allow freedom of action adopt approprite.

             latest development in knowledge in the various discplines as relavent to a building including  

 

 

 

 

Q3) List the five major steps that occur in project cycle . The steps should include from conceptualization of project to maintenance and final stage

 

ANS) 

1) Initiating phase:

                      the initiating phase of the project life cycle consists of just two separate process. the project charter and stackholder register. the point of these phase is to determine the vision for your                                        project, document what you hope to accomplish, and secure approvals from a sanctioning staceholder.

 

2) Planing phase:

                    The planning phase process group is where you built the project infrastructure that will enable to achieve your goal within your predetermined time and budget constraints, starting with a                                      project managemnt plan, project scope, work breakdown structure and more

 

3) Executing phase: where most of the project is allocated and most of the project deliverable and produced, you take your project plan and put it into action, whether that takes week,months or years 

                     managing terms effectively while orchestrating timeline expectations and reaching benchmarks goals. the execting phase often includes team development, stakeholder engagement, and                                      quality assurence activities, either on formal and informal basis. 

4) Monitoring and controlling phase: 

                    the monitoring and controlling phase involves keeping on eye on the actual progress of the project against your plan and taking corrective action where necessary

                   no amount of perfect planning will exempt you from the need to be constantly vigilant with tracking and reporting 

5) closing phase: 

                    the closing phase is the final phase of the project life cycle includes just one solitary process and its more than simply cheking of the project as done. its essential to formally close the project and                        secure the sign-off or approval from the customer, stackholders

 

 

Q4) Give examples of different disciplines involved in construction of a project

 

ANS)  Construction

          Finance and estimating 

          Contracts and bid

          Geotechnical 

          Management

          Structural

          surceying 

          Architect 

          Civil engineer 

          plumbing enginner 

          lift, Escalator and moving walk specialist 

          Acoustics specialist 

          Town planner  

 

 

Q5) How are buildings classified ? Place the following buildings under each category
             a. Four unit apartments
             b. School with capacity of 1000 students
             c. A single unit shop.
             d. Multi story Shopping complex
             e. Steel machine factory

 

ANS) 

A. Four unit apartments: Group A: Residential Building: 

                                        sub- division A-4

 

B. School with capacity of 1000 students: Group B: Educational Building

                                                                   sub- division B-2

 

C. A single unit shop: Group E: Mercantile Building 

                                   sub- division F-1

 

D. Multi story Shopping complex: Group E: Mercantile Building 

                                                      sub- division D-4

 

E. Steel machine factory: Group H: Industrial Building 

                                         sub- division G-1

 

 

Q6) Distinguish the roles of Design team and Management team

 

ANS) 

1) Design Team:  

     Helps to finalise the plan 

     Evakuationaries in the project

     Implementation the designs

     The design team is primarily responsible for taking your idea and bringing it to life using their professional skills. The end result is a design that aligns with the client's desires, is feasible, and is within  the             budgetary restrictions for the project.

 

2) Management Team: 

     Accomplishment of project 

     Execute the design 

     Achives the satifactory completion of the project

     The Executive Management Team is responsible for managing the Company's core business operations as a whole, which requires planning of various development processes, Group principles and                         Group practices, as well as monitoring the development of financial matters and Group business plans 

 

 

7) Refer to NBC, Identify the modeling requirements for the project ( from week 4).
            a. Height Limitations
            b. Area Limitations
            c. Room sizing
            d. Wall height
            e. Thickness based on fire life and safety
            f. Passageway requirements

 

ANS)

1) Height Limitation:  As per NBC 2005, clause C-2.5 the page no, 43

                                   height of the building shall not exceed 15m 

                                   a) for the building up to the height 15m, there is no need to provide lift 

                                   b) Housing for the low-income group shall preferably be up to a maximum of two storeys

                                   c) Building for housing beyound 15 m in height should be resorted to in exceptional circumstance and it should be governed by provisions laid down the code 

 

   here, in my plan case height of building is 4000mm = 4m so its belongs NBC code 

                                   

                           

 

 

2) Area Limitations:  AS per NBC C-2.3.1, page no 43

                                  According to NBC 2005, the minimum plot size with grount coverage not exceeding 75%, shall not be less than 40 sq.m in small and medium town and not less than 30 sq.m in                                                    metropolitan area 

  here in our case, the plan size is 9172X8327mm = 763.75 sq.m so we belong with NBC acts 

                                      

                                         

 

3) Room Sizing:  AS per NBC 2005, C-3.3, page no 43

                            the carpet area of multipurpose single room should be at least 12.5 m2. 

                            Such one room dwelling units with 12.5 m2 carpet area of habitable space is permitted only in case of on site rehabilitation of slum dwellers.

                            In a house of two rooms, first room shall not be less than 9.0 m2 with minimum width of 2.5 m and second room shall not be less than 6.5 m2 with a minimum width of 2.1 m provided the                                  total area of both the rooms is not less than 15.5 m2

                            In incremental housing the bigger room shall always be the first room.

                            

so here in our plan our room size is greater than minimum size criteria of NBC so we follow the NBC guidlines

           

 

 

4) Wall Height: According to NBC 2005: clause F-3.4, the minimum height of rooms and space should be 

                         The minimum height of rooms/spaces shall be as

                         follows:

                         a) Habitable room 2.75 m

                         b) Kitchen 2.6 m

                         c) Bath/water-closet 2.2 m

                         d) Corridor 2.1 m

                        F-3.4.1 In the case of sloping roofs, the average height of roof for habitable rooms shall be 2.75 m and the minimum height at eaves shall be 2.10 m.

            In our case wall height is 4m so we follow NBC act 

            

 

 

 

5) Thickness based on fire life and safety: the thickness for masonry walls is given by the Table 2 of fire and life safety section of NBC 2005 

                                                                    

             in our week 4 challenge we used external wall thickness is= 300mm 

             and internal wall thickness is = 200mm 

            so we are on NBC guidlines 

 

 

6) Passageway requirements: as per NBC 2005, table 1

                                                 

         we follow NBC guidline 

 

 

 

Q8) We have identified requirements for modeling from question 7, Use these numbers from code book and verify the numbers used in modeling the unit from week 2 to week 4. If the                   numbers are not reasonable, use the numbers obtained from the code book to create a revision of the mode.

       This model resembles the actual modeling requirements for Project 1 of course work

 

ANS)   

              

 

                            

 

 

 We follow all the NBC act mentioned in Q7 with our week 2 to week 4 challenge plan, so we not need to redesign our projects
