1 Digital Data in Geotechnics BDA 20 April 2016 Digital Geotechnical Data: An Informed Client s Perspective Paul Mellon Geotechnical Manager Transport Scotland

2 Transport Scotland The national transport agency for Scotland Responsible for delivering the Scottish Government s capital investment programme for the national road and rail networks Responsible for operating and upgrading Scotland s Trunk Road network

3 Transport Scotland

4 Transport Scotland - an Informed Client? Long appreciation of the importance of geotechnical data and its interpretation DMRB SH 4/89 Interface with Consultants and GI Contractors Interface with BGS, BSI, Geotechnical Asset Owners Forum, TRL

5 Investment in Geotechnical Data as a Risk Management Strategy Forth Replacement Crossing

6 Investment in Geotechnical Data as a Risk Management Strategy Extensive GI over 3 years 3 areas, 3 contractors Logging protocols agreed at interfaces AGS format specified All data to Tenderers Tenderers involved in GI Contractor able to rely on the GI data

7 Investment in Geotechnical Data as a Risk Management Strategy No unforeseen ground conditions!

8 The Geotechnical Asset

12 The Asset Management Cycle

13 The Asset Management Cycle Operate Maintain Plan Investigate Execute Design

14 The Asset Management Cycle The Geotechnical Data Cycle Operate Maintain Plan Investigate Geotechnical Data Execute Design

15 The Asset Management Cycle The Geotechnical Data Cycle Inspection and maintenance records Operate Maintain Plan Investigate Site investigation records Geotechnical Data Execute Execution records Design Design records

16 More Than Just Data

17 More Than Just Data Data Facts AGS Information Who, what, where, when Factual report Knowledge How GIR Understanding Why GDR Wisdom What is predicted to happen Design Monitoring plan

18 More Than Just Data Data Facts AGS Information Who, what, where, when Factual report Knowledge How GIR Understanding Why GDR Wisdom What is predicted to happen Design Monitoring plan Experience What really happens GFR

19 More Than Just Data - investigation and design Data Facts AGS Information Who, what, where, when Factual report Knowledge How GIR Understanding Why GDR Wisdom What is predicted to happen Design Monitoring plan Experience What really happens GFR

20 More Than Just Data - execution Data Facts Execution, monitoring, inspection records Information Who, what, where, when Graphical output Knowledge How Interpretation Understanding Why Interpretation Wisdom What is predicted to happen Design change Experience What really happens As-builts

21 More Than Just Data - operation and maintenance Data Facts Data points Information Who, what, where, when Inventory Inspection records Knowledge How Condition records Understanding Why Deterioration mechanisms Wisdom What is predicted to happen Service life Maintenance intervals Experience What really happens Performance records

27 AGS Data and beyond

28 AGS Data and beyond AGS Format a real benefit and industry-driven Adoption beyond UK GI industry BGS TS GI contract requires AGS data as output Developments in management of beyond Data (IKUW) (and E?) should be supported Even if recommendation is to adopt another format

29 BGS

30 BGS Liaison with BGS on data management ASK network NGDC Digital Data Portal

31 BIM

32 BIM Scottish Government target: Level 2 by April 2017 TS BIM Champion Assessing potential use on trunk road projects Aim to understand impact on operation and maintenance Develop an Improvement Plan

33 IRIS Asset Management System

34 IRIS Asset Management System A work in progress Work just starting on Geotechnical module Inventory Inspections Condition Deterioration Maintenance

35 Transport Scotland

36 Transport Scotland - ground investigation and design New GI framework agreement in operation Specifies data in AGS format Transfer of GI contractor s duty of care to construction D&B Contractor Renewal of Geotechnical Certification framework Update of SH 4/89 Consultant Consistency meetings for A9

37 Transport Scotland - execution Geotechnical Feedback Reports Digital management of As-built information

38 Transport Scotland - geotechnical asset management Populating Rockslope inspections Landslide monitoring
