11 FORMAT FOR STRUCTURAL DESIGN CALCULATION REPORT (For Professionally Engineered Buildings, Class "B") Part I: General data & load Calculation Introduction Building/Design Parameters Column Grid Plan with grid names & c/c dimensions Key Frame Diagrams with grid names & floor heights Dead/ Live Load Calculation Dead/ Live Load Calculation Calculation of Base Shear Distribution of Base Shear along the floor Distribution of Horizontal Seismic force in individual frames in X & Y/Z directions Load Cases & combinations used for analysis Part II: Analysis Part ( 2-D or 3-D analysis) Input Data figures: Frame Diagram Showing Node Numbers Frame Diagram Showing Element Numbers Frame Diagram showing earthquake loads in X- direction Frame Diagram showing earthquake loads in X direction Frame Diagram showing earthquake loads in Y/Z- direction Output Data results: Tabular data of Maximum Axial Load, moment & shear force for Typical Column Design Tabular data of Maximum Bending moments/ shear forces for Typical Beam/Slab Designs Tabular data of Maximum Axial Loads & moments for Typical foundation designs Part III : Sample Design Calculations Column Designs ( Corner & Centers each one type) Foundation Designs ( Typical Isolated, Combined footing, Raft & others) Beam Design ( critical one) Beam Design ( critical one) Slab Design (Critical panel) Note: Submission of calculation report on structural analysis and design of building in detail with more additional data, figures & examples will be highly appreciated

12 No objection certificate

13 LSMC KEY COMPONENTS OF IMPLEMENTATION BUIDING CODE IMPLEMENTATION OF BUILDING CODE DEFINE SYSTEM, PROCESS & POLICIES TRAINING/ORIENTATION AWARENESS PROGRAMS AT COMMUNITY LEVEL FIELD INSPECTION /MONITORING

14 Building Permit Process as per Building Bye laws & NBC First Stage Application By Owner Checking as per Bylaws Bldg. permit Section OK Checking as per NBC Eq. Safety Section OK Registration/ Tax pay Permit Process/ Notice/ Field verification Temporary permit Up to plinth Level

15 Second Stage/ Field Monitoring Building Permit Process as per Building Bye laws & NBC Application for Permanent Building Permit for Super Structure Field checking of construction Up to plinth level Bldg. permit Section & Eq. Safety Section jointly Field Reports by technicians/ Eq. section as per NBC OK Field Reports by technicians/ i Bldg. section as per Bylaws OK Permanent Building Permit /No objection Certificate

16 Third Stage/ Building Completion Building Permit Process as per Building Bye laws & NBC Application for Building completion Certificate Field checking of construction at different stages Field Reports by technician As per Bylaws/NBC OK Bldg. permit Section/ Earthquake Safety Section Issue Completion Certificate

17 Challenges for NBC implementation LSMC Professionalism & ethics still lagging among designers. Majority of design works are done by less competent/less qualified/ technicians/... less accountable! Local masons/contractors are still lagging in knowledge on earthquake resistance construction of buildings. Untrained masons working in low cost. Low Quality of construction works/materials Strengthening & Retrofitting of existing unsafe buildings Addition of stories in existing old buildings

18 Challenges for NBC implementation LSMC Negligence g & unwillingness of house owners to apply earthquake Safe techniques fearing of cost increment. Negligence knowingly/unknowingly about the importance of technical supervision & quality of construction works Need of Strong & effective Field monitoring/ inspection mechanism but we have less technical manpower

19 FUTURE STRATEGIES FOR EFFECTIVE IMPLEMENTATION OF BUILDING CODE

20 DEFINE SYSTEM, PROCESS & POLICIES LSMC Update & Modify existing system and process ( Counseling service) Introduce new Implementation policies Technical Input Updating Building code Introduce License system to Masons

21 LSMC TRAINING/ORIENTATION / CAPACITY BUILDING Oi Orientation i Programs To House Owners Training programs to Masons Training Programs to designers Refresher course to Municipal Technicians

22 LSMC AWARENESS PROGRAMS AT COMMUNITY LEVEL More publications i Installation of informative Hoaring Boards Radio releases in FM Stations Mass awareness Programs to community Awareness programs to school children

23 FIELD INSPECTION/MONITORING LSMC Formulation of Effective field Inspection Mechanism Mobile Clinic Introduce Inspection Card System
