Quantity Solutions Inc. was established in 2008 with a vision to create a Filipino engineering company that will serve local and international projects. It was established by Engr. Rynor G. Jamandre, a board topnotcher in Civil Engineering and one of the few Filipinos who is a certified member of the London-based Royal Institution of Chartered Surveyors (RICS) and Engr. Tim Cleveland, a US Military Engineer based in Washington.

QSI now employs over a hundred professionals after less than a decade of operations. It upgraded itself into a recognizable brand by implementing ISO 9001:2008 quality systems in 2013. Since its inception, it has completed more than 250 projects, mostly from notable developers in the Philippines and abroad.

In 2014, it partnered with Omnium International, based in Dubai, UAE to do multi-billion dollar projects for EMAAR Properties across the Middle East. This opened the doors for QSI to develop capabilities for international projects. In 2016, the company partnered with UK based Turner & Townsend to do multinational corporation portfolio projects in the Philippines and recently with Burns and McDonell of Kansas, USA.
