Have you ever wondered what an ITO is or what they do? Broadly speaking, the Technical Works Inspector (ITO) is the professional responsible for overseeing quality and correct execution in a construction project, as well as managing its document and financial control. As a result, this is a crucial field for the successful completion of a project, and one in which many architects can build a career. Yet, it is often an overlooked professional field with limited available information. For this reason, we outline its functions below and examine how current market demands have pushed the role toward a more comprehensive approach, as seen in the case of the firm Cero3.
The ITO is responsible for supervising compliance with contracts and legal requirements, ensuring higher quality and efficiency throughout the various stages of construction. In Chile, the General Law of Urbanism and Construction (Ley General de Urbanismo y Construcción) defines the ITO as the professional responsible for ensuring that everything is executed in accordance with regulations. During the construction process, they must ensure compliance with architectural projects, structural calculations, and engineering systems, including plans and technical specifications. They are even authorized to order partial demolitions when the work does not comply with what was stipulated.
Today, an increasingly demanding market has expanded this role beyond traditional inspection duties to meet the demand for a more integrated service, leading to the rise of project management. This shift benefits all stakeholders by minimizing errors and preventing, among other issues, construction delays, additional work caused by overlooked project variables, and—for contractors—increases in overhead costs due to schedule overruns.
Within this context, companies like Cero3 have emerged. Led by a team of architects with experience in design, construction, and inspection across various building typologies and programs, Cero3 aims to redefine the role of the ITO through a new perspective that directly involves the architect, offering construction management services.
Construction management begins at the project's inception, advising the client from the initial concept, market research, and feasibility studies—a phase often referred to as pre-investment. Next, the team coordinates the various engineering disciplines and provides design phase consulting. This early intervention helps identify conflicts before they reach the construction and quality control stages. Finally, the service includes post-handover support with the contracting firm.
Some of the projects where Cero3 has carried out these inspection and management tasks include:
