Profile and History


Trevor Williams Consulting Engineers (TWCE) is an Engineering Practice, providing a range of services pertaining to Fire Prevention and Protection as well as safety, related training, legal compliance and risk management.

In 2011, the South African insurance industry reported fire loss figures in excess of R5.7-million per day, that’s a staggering R238 000.00 per hour! This, added to the recent boom in the South African building industry has resulted in a situation, where fire protection systems, alongside other essential project components, may be compromised. TWCE designs complete fire safety systems and develops comprehensive protection programmes for their clients, who wish to limit the ever increasing risk of fire and resultant causalities as well as contain spiralling costs associated with fire losses.

TWCE was founded by Trevor Williams in 2003, in response to the growing need in the construction industry for reliable and dependable Fire Protection Consulting. To this day, Trevor Williams personally oversees all the daily operations of the firm.

The 'X' Factor

The company works from its offices in Centurion and is home to our highly skilled and fully qualified fire consultants. 

TWCE's top notch credentials include the fact that they are one of only a few specialist fire consulting firms in the country that are CESA accredited. To obtain CESA membership, a company is required to comply with a number of requirements, some of which include being ISO 9001 compliant, being in possession of a registered level of professional indemnity insurance and following a prescribed code of conduct. Another plus point is that TWCE has invested heavily in infrastructure which allows staff to connect to the company's IT system from anywhere in the world, as well as work from home and office. We have everything we need at our fingertips, anytime, anywhere.

Advancing Knowledge

One of the biggest issues that professional Consulting engineering firms face, is a lack of competence with no tertiary education qualification available specifically for Fire Engineering. What sets us apart are the decades of combined fire fighting experience, garnered by our management team. This practical experience, as an invaluable resource permeates the systems we design.

TWCE also supports further education and training of its staff whenever it can. For example, sending key staff to attend the world-renowned annual International Conference on Performance-Based Codes and Fire Safety Design Methods which has been held over the years in New Zealand, Sweden, Hong Kong and Australia.
