1 Authors and background System overview Case: The Kamppi Center Future research

2 Research background: Use of Line-of-Balance began in Finland in 1980s (HUT) Wide adoption in Finland by 1985 Now used by almost every construction company Authors: Line-of-Balance based schedule planning and control system Professor Jouko Kankainen: Helsinki University of Technology Construction Economics and Management Olli Seppänen (Ph.D. student): Operations research background Technology manager / DSS Inc. Development background: Before DYNAProject, there was a Line-of-Balance software on market which allowed conversion of Gantt Chart into Line-of-Balance DYNAProject was developed to replace the previous scheduling software Four big Finnish construction companies participated in the development work (June 2001 August 2002) References: DYNAProject More than 200 new users in year 2003 All leading construction companies in Finland, many small ones too Previous scheduling software is being replaced

3 Place Order of completion Work flow (m²) Space buffer Time buffer Time

4 ! A comprehensive time management system for construction projects Schedule planning Risk analysis Monitoring and control Reuse of completion data

5 " #$% "&''( Site location: Helsinki, Finland Project management by SRV Viitoset Ltd. One of the largest single city center projects in Europe Cost estimate: 2.5 billion Schedule: DYNAProject is currently being used in schedule planning and control of the Kamppi Center 6th of June 2003

6 " #$% "&''( Street level: Retail offices and shops Underground: Connection to subway Kamppi Park square Bus station (city of Espoo) Department store Retail outlets Pedestrian walkways for hotel Walk ways to city centre Pedestrian street Central bus station Kamppi market square Lasipalatsi square

7 " #$% "&) Master schedule: Just foundations and framework tasks are shown for every floor Phase schedule enables closer analysis: Place A and the tasks under Framework 2A under closer look Framework 2A

8 " #$% "&" Control chart shows task status: Foundations task is running late in some floors Forecasts show the expected delay of Foundations Alarm symbols show places where control actions are needed

9 " #$% "&" The total effect of the deviation of the Foundation is shown: Framework will be delayed for up to 2½ months Before control action: Control action (more resources) Framework is late only 2-3 weeks After control action

10 Improved schedule planning Control of work groups Evaluation of low cost / risk alternatives Continuous tasks Schedule compression less overhead costs Integrated procurement schedule Less risk in the schedule Time and cost savings Effective project control Graphical control features Total effects of deviations shown Optimal control actions in case of deviations More effective project control Increased productivity Less hurried work or waiting hours Schedule can be implemented as planned Software benefits All the tools needed in planning and controlling the schedule Easy to use graphical features Designed by industry experts, tested and used by project personnel

11 * More than 200 new users during 2003! DYNAProject1.2 improves project control and thus increases productivity. The schedule situation of the project can be seen at a glance! Vesa Tähti, Vice President, Skanska Finland DYNAProject1.2 is an innovation, which benefits the whole construction industry. Better schedule planning and control enables substantial cost savings. Jukka Pekkanen, Technology manager, RT (Confederation of Finnish Construction industries)

12 +' Cost and schedule effects of disturbances Cost loading the schedule tying payment schedule into tasks and places cost / schedule risks cost effects of control actions Integrating with 3D modeling software (4D) greatest value from 4D can be achieved by combining 4D with the Line-of-Balance pilot in Finland during fall 2003 / spring 2004 Integrating with the Last Planner Some DYNAProject pilot companies have also piloted Last Planner and want to have both in the same system We feel that the systems have a lot to contribute to each other

13 Complete system demonstration during the conference on request Q & A

14 , ) Total control of work and workgroups Planning based on the graphical Line-of-Balance Bill of materials Tasks under construction at any time Location of tasks Effects of tasks on each other Task information Line-of-Balance schedule

15 *$) Risk analysis features ensure feasibility ensures that schedule can be implemented as planned illustrates the probability of achieving milestones Risk input sheet graphically shows places where more control is needed Probability of achieving milestones Risks in the Line-of-balance

16 * Risk analysis indicates places where more control is needed

17 ,'" The use of control charts makes monitoring and control easy and effective Forecasts in the line of balance graphically illustrate the total effects of deviation The control chart for completions input, also works as a status report prompt for corrective measures Alarm Forecast Actual

18 "" Completion based forecasts are shown in the Line-of-Balance. Task status shown in different colors in the control chart

19 " Optimal control actions are planned to achieve the original schedule if deviations occur Control actions Alarm: control action needed Plan Forecast: task is late due to delay in previous task

21 $ In the Finnish system there are three features with which the fulfillment of starting prerequisites are ensured schedule s sensitivity to disturbance procurement schedule task plan» cost objective» master schedule task exploded» quality objectives and checking of design» resources» safety By combining task plans, it is possible to do look-ahead planning with DYNAProject (for example all the task plans for the next 6 weeks)

22 $ Master schedule task Floor covering works exploded
