About Us

TWCE Plantech is a professional consulting engineering company specialising in fire prevention and fire protection services and solutions.

Our Story

TWCE Plantech (formerly known as Trevor Williams Consulting Engineers) (TWCE) is a specialist consulting engineering company founded in 2003, in response to the growing need in the construction industry for reliable and dependable Fire Protection Consulting.

In 2011, the South African insurance industry reported fire loss figures in excess of RS.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.

In 2018, TWCE became part of PLANTECH, a consulting engineering company based in Pretoria.  The new company called TWCE Plantech  and headed up by Managing Director Jaco Prinsloo has the same personnel and levels of service excellence which has been maintained with clients over the last sixteen years.

Plantech, TWCE’s sister company have expanded throughout South Africa, Lesotho, Nigeria, Mauritius and India. Plantech’s head office which is situated in Pretoria employs more than 20 engineers, technicians and support personnel.

With a strong work ethic and dedication to exceptional client service and professionalism, Plantech’s extensive electrical, electronic and mechanical engineering knowledge and experience is applied to delivering optimum and viable solutions ensuring that clients projects are completed on time, within budget and of the best quality possible.

With benefits of increased technical, drafting and support staff resources TWCE Plantech is set to grow and flourish providing clients with an even better service.

TWCE Plantech’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 Plantech 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.

X Factor

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 Plantech 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.

TWCE Plantech 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 spiraling costs associated with fire losses. Since its inception TWCE Plantech has enjoyed substantial success in establishing itself as a leading fire safety engineering consultancy in South Africa.

TWCE Plantech has a documented quality control system as well as having ISO 9001:2015 certification.
