Trimble Tilos

Trimble Tilos is a scheduling tool for linear construction projects, where the work moves along a corridor. Examples are roads, railways, pipelines, tunnels and transmission lines. A standard Gantt bar shows only time. Tilos plots each activity against both time and distance in a time-location diagram, so planners can see where crews and equipment will be on the route at any date. They can also spot clashes between activities and test what-if sequences. Planners can schedule quantities, production rates, costs and resources. They can record actual progress and overlay cost and resource histograms or mass haul diagrams on the site plan. Tilos began at Linear project GmbH, which Trimble announced it had acquired in March 2015. It now sits within Trimble's civil construction portfolio. Tilos exchanges schedules with Microsoft Project, Primavera and Asta Powerproject. It also connects to Trimble tools such as Business Center, Tekla Civil, Novapoint, Quadri, Trimble Connect and WorksOS, and it can produce Excel reports. Trimble does not publish prices, so buyers need to ask for a quote. Third-party directories list figures that conflict, from about 2,095 USD per user per year to a one-time fee of about 4,290 USD. Tilos suits heavy civil contractors, engineering firms and infrastructure owners. Its main limitation is its narrow focus. It is a specialist planning tool, not a general team work manager, and it adds little for building or office projects that are not linear. Reviewers also mention a learning curve for people new to time-location planning.
