Building Control

From e-permitting via modelchecking to part of customersprocesses

• Started in May 2014• All single houses 11/2014, All permits 11/2015, site inspections

11/2016, archive 1/2017, BIM inspections 11/2017

• Conserns all activities• Application, consultation, decision making, statistics and archive

• No papers in any part on the process

• Lupapiste.fi/ Evolta system• Operating system

• Developed under umbrella of Ministry of Environment

• Operator Evolta Oy

Why digital building permissionprocess ?• Design is already in 3D as is the Construction

coming with speed

• Building control personnel are used to digital tools

• All plans can be saved to pdf ( before prints )

• Why send printed plans to building control whenyou con deliver them digitally ?

• All 3D plans can be saved on IFC

- allmost 90 % of information saved

• Why transform 3D plans to 2D (pdf)• Lots of information lost

BenefitsOwner/Applicant

Easy access

Inqueries platformBasic data for planning (City plan, pipelines, enviromental facts etc.Answers documented

Monitoring directly of building control process JOT 24/7 ( direct information

No printing costs

Also access to discussions of building control and planners

Database of official documents

Notice to neihbours

Shorter building control processPossibility to use the comprehensive City Model in marketing purposes

BenefitsMain architect, PlannnersMain ingenieur (site )

All official documents and opinions in one place 24/7Master plann, data , archive

Easy to contact and ask from building controll

No working ours restrictions

All plans, discussions and comments open for participants

Everyone has uppdated plans in use

On the backround all official databases/maps/plans

Faster and more accurat process

No printing, less meetins in building control officeEasy correction of plans

Site inspection noticies directly documented

Possibility to 3D processes and new tools

BenefitsBuilding control and officials

Same updated database for all

Simultanious opinions at the same time (fire department, road access, pipelines etc.)

Possibility to work and independent of working ours and place

Better control of working list

Possibility for deputies to help during vacations

Faster and more accurat processes

Possibility to contact ans ask all the time to planners and ownerNo papers and elecronical archive all the time in useSite control can all be done on site. No extra writing in office.Efficency grows 30 %. Less personnel, less space, happy personnel (possibility to work home) In future 3D model checking (Solibri) and comprehensive City Model

Solibri Automated checking up to 70 %Solibri is a originally Finnish software for IFC model checking, acquired by Nemetcheck, Germany

Page 22: Challenges and experiences to implement digital building ... · KIRA-digi project (Case Pumppupuisto) Osallistujat: Vantaan rakennusvalvonta Hyvinkään rakennusvalvonta Järvenpään

Rule base checking• Automated checking is based on rules

• Algorithms on the background analyzes all model components• Component dimensions• Collisions• Property values• Behavior• Relations

• Rules are collected into Rulesets• A Ruleset can consist of several sub

rulesets• Default ruleset of roles are included

in the installer• Rule parameters can be edited and

saved within the model

We are using Solibri rules for apartment buildings and private houses made specifically for building permission office and using Finnish building law requirements
