Many of our services fall outside of the conventional model of outsourcing; our clients previously handled such tasks in-house. But when firms utilize our resources – especially for repetitive, low-margin, commoditized and subcontracted work – they gain several significant advantages. Our services allow clients to finish projects on-time or ahead of schedule, increase capacity to take on more work, bid more jobs and larger projects with increased confidence, free up critical internal manpower and ultimately increase revenue.


Regardless of industry or project type, we always help our clients to: Win More Business, Enhance Resources, Reduce Costs and Offer More Services. Through a variety of mechanisms – from cost efficient and superior detailing to overseas cost structures and construction administration services – our adherence to these value propositions distills our wide range of offerings into clear, tangible impacts on a client’s business.

Ultimately, Prothious’ value propositions and strengths enable clients to gain several crucial advantages that will put them ahead of the competition.
