We’ve been utilising Dewick & Associates O&M Manual services for several years now; its due to their technical abilities and attention to detail in our sector, that we keep coming back to them.

Time is often of the essence for us; which is why we like to work with Fiona Thaiyah at Dewick, as she makes the full process of compiling the O&M Manual very fluid throughout, mainly due to Fiona’s communication skills and quick responses to our correspondence, which is always second to none. We hope to work with Dewick and Fiona for many years to come.

We have found Dewick & Associates to be most professional and approachable on all current and past projects under our remit.
I have found both Management and admin staff to be capable and suitably experienced as they approached each and every project with enthusiasm and energy.
All projects have been completed on schedule to a high standard.
