You would buy door hardware in hundreds, costing thousands of dollars while constructing a commercial building. Long term planning in selecting appropriate door lock hardware will help prevent, replacements, repairs and maintenance. Of the innumerable points to keep in mind, here are a few. 
Insurance:
Insurance companies will check whether the building has burglarproof, strong, and ANSI (American National Standard Institute) grade locks at the time of booking the policy. Should there be a claim; insurance companies will definitely asses the security rating of the door lock. Hardware fixed to the door, such as the hinges, alarm locks too will come under scrutiny. More than worrying about Insurance, adopting ‘prevention is better than cure’ policy goes a long a way in reducing hazards and losses.
Door Lock Hardware Types:
Buy door hardware based on non-price performance appraisal and cost-related business decisions. Purpose goes to determine the type of a door lock. Hardware such as hinges, latches, and knobs have both utility and decorative aspects, while you have to consider durability and ease-of-use for door and frame closers, jambs and jams and so on. A few examples would help.
Fore remotely operated doors, you need electric strikes and special hinges that transfer low-voltage current to the activators. Just for separating public and private areas in a building, you could opt for a simpler mechanical pushbutton lock. On the other hand, door lock hardware for storerooms and sensitive areas will need fire rated, ANSI grade 1 locks, and deadbolts.
As such, before you buy door hardware, check out product catalogues online; you will gain several useful pointers to discuss with the architects or construction firm.
The Costs:
For a factory or commercial building, you would spend thousands of dollars on door lock hardware; the cost will go up if you need high-security rated and sophisticated alarm locks, electrically operated door closers, or heavy-duty hardware. For instance, extra heavy-duty classroom security lever costs over $300. This is the price at an online store, so don’t be surprised if the local store quoted a higher price. Over and above the lower price, online stores offer quantity discounts on certain door lock hardware.
