Wellington City’s 3-Water Assets Problem
Here’s where we started….
Data Quality – low mathematical precision < 35%(data confidence)
Data Consistancy < 30%(data completeness)
Data not aligned
Data not integrated (‘joined up’ or ‘accessible’)
Advanced analytics simply not possible
.........off to the drawing board

The Benefits
Captured Interdisciplinary Benefits
Balanced / Informed evidence-based decision-making
Interdisciplinary Benefits – In Practice
Engineering (Asset / BU)
• Forwards Works Programs – clear line of sight• Investigation (e.g. Condition Assesments, R&M,
Materials Sampling, CCTV) • Replacement (incl. Interactivity – Roading Reseals vs.
Pipe Renewals)
• Carrying ‘Risk’ – on Criticality Paradigm (e.g. Run-to-Fail)
• Asset Performance (Practical & Financial)
Interdisciplinary Benefits – In Practice
Financial
• Forwards Works Programs – transparency (30+ years)Renewals Forecasting (depreciation commitments)Growth Forecasting (LOS and Dev. Cont. Commitments)
• WCC Borrowing Implications (e.g. Funding Caps)
• Asset Performance Financial – Economic Development Headroom
• Carrying ‘Risk’ – on Cost / Benefit / Risk Paradigm
• Meeting OAG Audit Requirements 30 year Infrastructure Plan
Interdisciplinary Benefits – In Practice
Interdisciplinary Benefits – In Practice
Spatial Planning
• Economic Development (evidence base decision-making)• Economic Utility – Optimised urban planning –
infrastructural capacity• Opportunity Cost of Investment – by Suburb (e.g.
Karori vs. Mirimar vs. Linclonshire Farm)
• Spatial Planning • Capacity Metrics – e.g. HEU’s maximum density• Social Metrics – e.g. Walking distance to a park

Practical Vision – Returning to ‘First Principles’
Doing the ‘BASICS’ well...
Here’s where we started are (<2 years)….
Data Quality – low mathematical precision < 35% / 68%(data confidence)
Data Consistancy < 30% / 73%(data completeness)
Data not aligned / Data Aligned
Data not integrated (‘joined up’ or ‘accessible’) / Data Integrated
Advanced analytics simply not possible / possible & proven

Some ‘Cool Stuff’
Electronic Transfer from BIM to WCC Asset Database SPM• Taking information from Building Design through to As Built
documentation and transferring it to Asset Management Database to allow for Analysis of Assets.
• Also useful for Facilities Management of the Building asset with both Database information & 3D model
• Less input/cost into setting up building information in Database• Higher quality & accurate information to allow better management of
building
Proof of Concept 1
• Using Revit model of an existing 5 unit stand alone site, populating the model & then transferring information via Access or Excel to then transfer information into SPM
• Existing information in SPM• Model designed in 2 parts. A site
model with individual buildings linked to site
SPM OUTPUT ON PROJECT IN EXCEL
SPM INFO FOR REVIT
How Revit Stores information
Revit can schedule these parameters
BIM to Database• Main BIM software in buildings is Archicad, Revit, Bently &
Vectorworks. Predominantly Revit & Archicad used by Architects & Engineers on buildings.
• Vendor neutral or common methods of data transfer• Revit DB Link & Schedule to Excel both freeware add=-ins to Revit• To import into SPM only so much information required from Model,
so an intermediate step is needed• Excel & Access are used as common software that can manage
the amount of data exported from Revit. Excel more common in construction industry
• An important next step is developing a validation process to insure all relevant fields are not empty and in correct format
Data Exchange Revit DB link• Exporting from Revit Model for this project was
successful to both Access & Excel.• Information overload. Exporting data from this model
into Excel created over 250 worksheets with over 3500 headers. These are the generic Revit exports of all Family types, whether there are any actual families in model or not.
• Trying to find relevant fields was difficult to get to
Revit Schedule to Excel• This only exported what was in schedule, so could be more
targeted.• Shared parameters that matched SPM database were developed
and put into Revit at Project & Family (component ) level.• Each individual family had to have its own schedule.• These were exported to individual Excel files• One file (Ceilings) was imported into SPM and then exported again
to give SPM Unique Key to component• This was then successfully transferred back into the Model. So
individual component in model has SPM key assigned to it.
Lessons Learned to Date on Standalone• We have demonstrated a 2 way link between 3D model & SPM database, using
shared parameters to harmonise fields between SPM and Model• The process used is cumbersome using schedules, so for larger projects the Full
Export to Excel or Access will need to be investigated with setup search functions to obtain relevant information
• Generally most elements & components fall into the Database Hierarchy but a few items do not schedule well at present
• Walls do not schedule by space. As a family they have 2 sides so relate to spaces either side. In the Wall Schedule or Material take off the information falls out by wall types, which is not useful. Further investigation is required.
• A further step is to explore services which extend through site & rooms such as hot or cold water pipes and drainage
• And the next project for Proof of Concept is……….
