Do you want a control system designing for your new or existing project ?

If yes, then all you have to supply is a description of operation and an Input/Output points list, and i will do the rest.

For your FREE no obligation quote go to http://bms.system-maintenance.com or http://tridium.business-maintenance.com and enter some basic information into the online contact form.

A little about me, I am a Tridium certified controls programmer and have a HND in electrical / electronic engineering as well as being 17th edition wiring regulations certified. I have a valid JIB CSCS card so there is no problem with goning onto any construction site / site inductions.

As well as working on a daily basis with the Tridium Niagara platform I also work with touch screen HMI (Maple Systems) and Seimens LOGO plc for small projects.
I have designed projects from small underfloor heating systems for domestic houses to large complex commercial heating and cooling systems, so no job is to smal or to large.

I have designed software for Kier, Balfour Beatty plc, BAM, Land Securities and many more large companys.

So just give me a try for your control design software, you will be happy with the design as well as the price, thats a promise.

Waiting for your to contactnme, regards Paul.
