Much of construction on soft ground is observational since it is difficult to accurately predict the amount or rate of consolidation of foundation materials subject to embankment and other construction loads. There is a constant need to review consolidation performance and forecast forwards to determine areas where additional treatment may be required.
The MissionOS is designed for distributed processing and management of the resulting time series data. Links to raw metadata are provided at the record level and provide ready access to the background information. The key objectives of the design team for earthworks is to achieve the desired foundation stiffness within the target construction period and for future settlements after the laying of the wearing course or rails to be limited to within acceptable levels and distributed evenly so that pavement performance is assured. In order for this to happen data must be collected from a wide array of instruments, combined with topographic survey of embankments and progress monitoring of pile and other ground improvement techniques. This must all be constantly reviewed against design prediction.
Understanding the ground and its parameters is key to any understanding of ground behaviour. MissionOS acts as a repository for all your GI information stored in standard AGS tables. Since the data is held on the web draft borehole information can be quickly loaded from site so that designers are operating on the latest data.

Topographic survey data for the current fill levels is key to understanding embankment behaviour. Data includes manual levelling of settlement plates, standard ridge line surveys managed in packages such as surpac and information from automated graders with GPS locators. This data can be used to give accurate depictions of the level of filling at a particular location.
Earthworks require a lot of testing to determine the state of compaction of the fill including sand replacement and insitu bearing tests. These data can also be loaded within the MIssionOS along with their accompanying reports.
MissionOS gives you the ability to produce a wide variety of reports using our custom canvas tool. Over a number of projects we have developed a variety of analysis types which were coded for automatic generation:
