Section 44ad

I am providing Construction Services & IT consulting. For the purpose of computing Business Income I want to consider Construction Services u/s 44AD and IT consulting under normal business income. Common expenses are incurred for providing both the services. My assets include car & a bike. I want to allocate 40% of expenses excluding depreciation to IT Consulting. Car & bike is used for providing both the services. Since I cant claim depreciation u/s 44AD, can I claim 100% of depreciation from IT Consulting as?
