HOW MOSAIC WORKS
Applicable at any stage. Updated as knowledge grows.
Ground uncertainty does not resolve itself at contract award. Mosaic is a SaaS platform that can be applied at any point in a project lifecycle; from early planning through construction completion; and continuously updating its probabilistic ground model as new data arrives.
DURING PLANNING AND PROCUREMENT:
01.
Quantify geotechnical variability
Identify where uncertainty is highest and where additional investigation will reduce risk most effectively. Direct investigation budgets to where they matter.
03.
Evaluate programme and cost exposure
Assess the impact of geotechnical variability on initial programme estimates before commitment. Contingency resourced against evidence, not optimism.
02.
Inform contractual risk allocation
Understand the residual risks from GBR baselines relative to the available data and geological model. Tenderers can assess their exposure. Clients can evaluate the quality of bids.
04.
Centralised Tender Information
A shared database for communication of geotechnical data and uncertainty across the project team — owner, designer, and contractor working from the same model.​​
DURING CONSTRUCTION:
01.
​Integration of new data
As construction proceeds, new information — probing, geophysics, TBM performance data, monitoring — is integrated to update and recalibrate the ground model continuously.
03.
Optimised preparedness
Updated risk forecasts inform changes to TBM operating parameters, support decisions about additional investigation, and enable intervention before conditions deteriorate.
02.
Forecast vs. Actual
Evaluate geotechnical models against initial predictions. Deviations from baseline are identified early — before they become claims or losses.
04.
Defensible record
Legal remedies and insurance are no substitute for facilitated performance. Mosaic maintains a version-controlled record of expected versus encountered conditions for the life of the project.
DATA INPUTS (AT ANY STAGE):
​​​​Borehole & laboratory
Muography
Geophysical surveys
TBM telemetry
Probing & lookahead
Instrumentation & monitoring
DELIVERING FOR YOUR PROJECT:
RISK ASSURANCE
Transparent, quantified uncertainty that all parties can interrogate and rely upon.
​
OPTIMAL PREPAREDNESS
Timely decisions based on the best available ground model, not last month's data.
​
RISK MONITORING CONTROL
Continuous comparison of forecast and actual, with early warning when it matters.
WHY GOOD QUANTIFICATION MATTERS
The ground is certain. Our knowledge of it is not.
​Evidence from decades of major project commercial losses points to the same upstream shortcoming: ground condition uncertainty poorly defined and allocated at contract formation.
​
But a GBR is only as defensible as the uncertainty quantification behind it.
​
"However unexpected the ground conditions prove to be, it is better to have a defined base for the tenders so that it is known where the incidence of the resulting cost will lie."​
- CIRIA 79 (a principle unchanged in forty years)
​
Mosaic provides the quantitative foundation for that defined base — and continues updating it throughout construction as new evidence accumulates.​​​​
​Where Mosaic Operates:
01.
Planning & Investigation
Quantify uncertainty before procurement.
Geostatistical modelling identifies zones of high uncertainty and guides further investigation. Contingency is resourced against evidence, not optimism.
02.
GBR Preparation
Defensible baselines, no assumptions.
Mosaic provides the probabilistic ground model that underpins baseline drafting. Uncertainty relative to each baseline is quantified and documented — creating a traceable basis for risk allocation.
03.
ECI & Tender
Shared platform, aligned understanding.
Accessible to owner, contractor teams, and independent advisers simultaneously. Information asymmetry — the condition that generates most ground risk disputes — is structurally reduced before commitment.
04.
Construction
Live forecast vs actual comparison.
TBM data, monitoring, and survey feed continuous model updates. Deviations from baseline trigger early warnings. The record of expected versus encountered conditions is maintained for the life of the project.
