This is a letter of reference for the above named company. We have and will continue to utilize this company for all our structured cabling needs. This organization is highly trained, highly professional, and is always willing to do what it takes to get the job done.

TECHSICO started cabling BOK properties in December of 2006. The work completed has ranged from day to day MAC work to complete Data Center Design and build out. Currently they are finishing up on our OKC Data Center. This project has consisted of building out 4 Com Rooms, 300+ Cat6 Drops, 1500ft - 24 str MM fiber and a 300pr Cat3 Dmark Extension. As you can tell our project's can require installation of transport equipment, cable splicing, fiber, copper, and system configurations.
