These temporary structures were necessary to provide a safe and stable working environment for workers and to support the permanent structures during construction.

In the early days, TWS was developed and managed by contractors and workers themselves, without much input from engineers or designers. It was considered more of a construction activity rather than an engineering discipline. However, with the increasing complexity and scale of construction projects, the need for a systematic approach to TWS became apparent.

In the early 20th century, engineers began to take a more active role in the design and management of TWS. This was also the time when the term “temporary works” was first coined, and it started to gain recognition as a distinct engineering discipline.

The increasing focus on safety and risk management in the construction industry also played a significant role in the development of TWS. As construction projects became more complex and challenging, the need for proper planning and design of temporary structures became crucial to ensure the safety of workers and the success of the project.

In the 1960s and 1970s, TWS started to gain more recognition and attention from professional bodies and organizations. Various guidelines and codes of practice were developed to standardize the design, installation, and management of TWS. This led to the formalization of TWS as an engineering discipline, with the development of courses and qualifications specifically focused on TWS.

The 1980s saw the widespread use of computer-aided design and analysis tools in the design of temporary structures, which further enhanced their efficiency and safety. In the following decades, TWS continued to evolve with advancements in technology and materials, resulting in more innovative and complex temporary structures being used in construction projects.

Today, TWS is an essential aspect of construction engineering, with dedicated teams and professionals responsible for the design, installation, and management of temporary structures in a wide range of projects. The history of TWS has shown its significant role in ensuring the safety, efficiency, and success of construction projects, and it continues to play a vital part in the ever-evolving construction industry.
