Communication and teamwork are also vital in CIPP projects. The rehabilitation process often involves multiple stakeholders, including project managers, engineers, field technicians and suppliers. Effective collaboration is essential to ensure that everyone is aligned on project goals, timelines, and safety measures. This necessitates strong interpersonal skills and the ability to articulate technical concepts to team members who may have varying levels of understanding.
In the early days, the margins were so high for small diameter projects that the contractor would play suppliers off, use cheaper non approved materials and many issues ensued. Very little training and winging it was normal.
days, and the cure time in small diameter estimated as supplier input was minimal, and the contractor through trial and error in estimating the cure time. Ground conditions and loadings were never properly understood. Hence many liners failed. Most of this was with the smaller or medium-sized contractors where the volume of work with trenchless was minimal and they often did not have the technology or training/understanding.
Many projects were hit or miss in the early days, lack of proper cleaning, not understanding infiltration of ground water temperatures. Mixing the resins in the warm sun. Often the resin would cure before it was poured into the liner. It was

disposal, emissions, and environmental impact is essential for project success. Workers must be trained in compliance protocols and environmental best practices, emphasizing the importance of sustainability in modern rehabilitation efforts.
Today, supplier, contractors tend to work closer together. Training, understanding, testing and approvals are the norm. As the industry and market grows, I see so much more collaboration between the parties, larger projects, more complex projects. Innovation and better understanding from the suppliers of the field requirements, systems needs, project demands. A higher skill is needed and training is provided and recognized, however the systems are becoming much
