We have used TCA services for many years, predominately their estimating service. I have personally found them to be professional, timely, and helpful. Often tendering can be time sensitive and complicated; I have found TCA always provides a prompt and efficient service. Their willingness to be flexible, revisit and tailor our tenders to ensure we both do our best to win viable projects. I would go as far as to say they are invaluable. Due to their knowledge and experience in the building field they enable us to offer a fair and competitive tender to our clients whilst maintaining a healthy profit for us. I strongly recommend Thomas Callum Associate and their team of highly skilled Quantity Surveyors, Estimators, and Construction Consultants. I feel confident they are sure to exceed your expectations.

Having had the opportunity to work closely for several years with Paul Arnell, I can attest to their exceptional professionalism, quality of work, and commitment to excellence. Thomas Callum Associates Ltd has consistently demonstrated their expertise and dedication in their respective fields. Their attention to detail and ability to deliver high-quality results are commendable. They possess in-depth knowledge and skills that are evident in the successful completion of tenders and their contributions to our business. Furthermore, I have been impressed by Paul's strong work ethic and reliability. They consistently meet deadlines and exhibit a proactive approach in tackling challenges. Their excellent communication skills and ability to collaborate effectively with us have contributed significantly to the success of our new projects. I highly recommend Thomas Callum Associates Ltd for any business or partnership. Their professionalism, integrity, and commitment to delivering exceptional results make them an asset to any organisation or project.

We have been working with Thomas Callum for the last 5 years, using them to price tenders to include site visits and meeting the clients, putting specifications together and costing BoQ’s. We have also used them to do valuations on bigger more complicated projects. We have been successful on a good number of these and on completion we have been pleased with the resulting margin. We have found them to be responsive to queries, helpful and friendly and consider them to be an extension of our own business.

We employed Thomas Callum Associates when we were having a bad time with some building contractors who took us for a ride and eventually went into receivership. We feel that if Mark had been involved from the start of the project we would not have ended up in the same situation. Mark then led us through finding a second contractor and was with us all the way and made sure that the project was completed in a reasonable time frame and to the correct standard. We would recommend the company to anyone who is considering a home building project to ensure that they have a successful outcome.

We at RM Construction have worked with Paul, Karen and the team for over four years now. They have provided us with estimating services over this period. We have no hesitation in the recommendation of the firm and their professional consultants. They have always returned tenders promptly and to a very high standard with a very useful amount of detail.

Since working with Mark, the stress of this project has significantly reduced as I know my best interests are being looked after. Mark's experience has helped us to have hindsight and navigate issues before they become larger problems. Mark has always been very responsive and easy to communicate with.

We have worked with Thomas Callum Associates over the past couple of years, on several of our projects. They have provided us with commercial services such as procurement, interim valuations, variation assessment and submission, settlement of extension of time claims and final accounts. We have found them to be professional, timely and helpful. We have no hesitation in recommending their services.
