Looking at your Telephone Contact, I believe you are stationed in India.
For any Structural Design, including its analysis and design of structural components, you will need to follow ALL the Indian Standard Codes, as related to Loads, Load-Combinations, Wind-Loads, Seismic Loads, etc. For ALL these inputs, best option could be to use software like E-Tab, and alike, but I find the E-Tabs as most suited, since it offers design and analysis as per Indian Standard Codes, too.
For foundation, you will need a Geo-technical investigating Agency, to provide you information about the Type of Foundations, the Load-bearing Capacities etc. etc.
This would also depend upon, the Scope/Height of Buildings, as also which Earthquake Zone, as per Indian Standards Codes, that the site of proposed development is situated
