Suggestion For Salary

Hello,
I am site Engineer/Manager in installation field and handling whole project by myself. I have to live on site and work across PAN india. my company is paying my rent, providing food and travel allowance. and paying me decent money. But I would like to know is there any site allowance apart from food and rent I can claim?? and is there any industry standard of salary for someone who is managing whole project by self( approx. project cost 1.5cr per month).
Thanks

It s good that your company is paying food allowance plus travel allowance which come under Site expenses
also if the company is paying rent then check the rent amount as per tax wise and cost wise like if you are staying at bang lore then rent is different and if you are staying pune then also it is different
if you want to claim then you can claim for telephone experiences, in other expenses you can mention like fax expenses, small expenses which you did on site
