Using the PN2023 BAA Retail / Office Complex Plan Pack and documentation, carry out the following tasks to check and assess the structural adequacy of the building.

 Using the BAA project plans, specifications and documentation, and the information below, calculate the total load on the column pad footing at Grid D2.

1. • Wind load to the roof: 1.2kPa
   • Live load to the roof: 0.5kPa
   • Roof Sheeting, Purlins, insulation, fixing and bracing, allow 17.5 kg/m2
   • Use the internet to research the weight of the rafter and column elements of the structure
   • 250 UB 37.3 Rafter
   • Universal Column 310 UC 137
   • Reinforced concrete density 2400 kg/m3

2.Using the determination calculated above and the project documentation, identify whether the footing size is sufficient to meet the structural requirements

3.Analyse the stability of the soil to support the construction load and if the footing is found not to be sufficient, then calculate the ideal size for the new footing and show your calculations

4.Describe what design changes could be made to address this including design change measurements. Use the Geotechnical report to confirm.

5. Describe how these changes would be certified and implemented to ensure compliance with NCC/BCA requirements including Industry Professionals and their role in the process.
