The construction industry relies on innovation to improve project delivery and team performance. In this case study, we explore how a site diary app supported a major sewer system upgrade project in Central London.
The project involved complex coordination, multiple stakeholders, and a live operational environment. To understand the impact of digital reporting, Shane Uppal spoke with Jack Beaumont, Site Manager at Costain.
Who Is Jack and What Does He Do?
As a Site Manager, Jack plays a critical role in the successful delivery of construction projects. He coordinates site resources, manages the site team, and ensures activities progress safely and efficiently.
At the time of the interview, Jack was leading a sewer system upgrade project in Central London. His responsibilities included managing site operations, overseeing groundwork activities, planning future works, and coordinating multiple suppliers.
The Problem
For Jack, keeping track of site progress and recording what happens on site is essential.
However, construction projects generate a huge amount of information every day. Furthermore, no single person can be everywhere at once. As a result, important details can easily be forgotten, especially when trying to recall the exact time, location, or sequence of events.
Jack recognised the need for a site diary app that would make information easier to record, organise, and retrieve. He also wanted a solution that allowed users to search and filter records quickly using different data fields.
Moreover, the mobile functionality appealed to the team because it enabled information to be captured immediately while events were still fresh and accurate.
The Results
The biggest improvement Jack noticed was the quality of the records being created.
With Site Diary, information moved quickly between teams and remained accessible whenever needed. As a result, the project team could maintain stronger visibility across multiple work areas.
Jack also highlighted the simplicity of the platform. Since construction teams regularly work with new people, he found that an intuitive site diary app made adoption much easier.
In addition, the mobile functionality allowed teams working across several locations to share information in real time. Progress updates and site knowledge could therefore be captured, stored, and distributed quickly.
Ultimately, Site Diary app helped the team document progress more effectively while improving communication between project stakeholders.
How the Changes Impacted the Team
Jack acknowledged that moving from paper-based processes to digital reporting is rarely straightforward.
However, the intuitive interface helped smooth the transition. Furthermore, site teams could clearly see that information submitted from the field was being received and acted upon by the back-office team.
At the same time, Costain was expanding from a single site operation to managing several sites. Consequently, Site Diary became increasingly valuable as the team grew.
Jack also noted that the pricing structure suited the company's scaling requirements, making it easier to roll the solution out across additional projects.

"It has allowed the team to quickly get a feel for progress on site and share progress photos."

Conclusion
For Costain, implementing a site diary app improved the way project information was captured and shared across a complex sewer infrastructure project.
The solution helped create stronger records, improved information flow, and enabled real-time collaboration across multiple sites. Moreover, its ease of use supported adoption among growing project teams.
