Name the 9 steps to design a schedules.
1. Set up diagram
2. Plot milestones
3. Identify working time
4. Forward pass
5. Illustrate work packages
6. Backward pass
7. Illustrate time buffers
8. Identify critical path
Name 3 Illustration paths for Scheduling.
- Bar Chart
- Gantt Chart
- Network diagramm
Quickly describe the Bar Chart and name some pros and cons.
+ Simple
+ Clearly arranged
+ Accessible
Quickly describe the Gantt Chart and name some pros and cons.
+ prints out the relationsips btw. work packages
+ quantifiable casual dependencies
Quickly describe the Network diagram and name some pros and cons. Name also de meaning of the different numbers. How can you calculate the critical path?
+ points complex interdependencies
-> only for complex projects!
What exactely does the "Forward pass" and "Backwards Pass" and the "Critical Path" describe?
Forward: Earliest finish day.
Backward: Latest finish day.
Critical Path: The critical path is the longest path of the network diagram. The activities in the critical path have an effect on the deadline of the project. If an activity of this path is delayed, the project will be delayed.
Name 4 different Types of costs and explain them.
Land Cost (LC)
Building Cost (BC)
Basement excavation, Structure, Finishing, nstallation: Electrical, HVAC, Sanitary, Transport,
Production Cost (PC)
= BC + Special Equipment and services + Esternal Work + Furnishing + Incidentals and dues + Fees
Investment Cost (IC)
= PC + Land cost
Name the 9 "building cost classifications" according to the Swiss Manual
BCC1: Preparatory Work
BCC2: Building
BCC3 Specials
BCC4: External Work
BCC5: Incidental Costs (beiläufige Kosten)
BCC6-8: Reserve
BCC9: Furnishings
What Points are included in BCC2 "Building"?
- Basement excavation
- Structure
- Electrical installations
- HVAC installations
- Sanitary installations
- Transport installations
- Finishing Work
Look at the relative cost structure of those 4 Projects. What kind of Project could this be? Give reaons!
A: Hostel
- No reserves
B: Hospital refurbishment
- High Preparatory work -> refurbishment
- High Costs for public procurement and credit -> public building
-
C: Hospital / School new building?
- High Reserves -> Public building?
- Lower Preparatory work than refurbishment
D: Hotel
- High Furnishing cost
- High External Cost (Garden)
There are different types of costing depending on which project delivery phase it is made. Name them with its accuracy.
Draw a graph of the costings depending on the project delivery phase and level of detail.
Preliminary Studies: Approximate estimate of costs
Project - Conceptual Studies: Cost Estimate (+/- 15%)
Project - Design Development: Costplan (+/- 10%)
Name 4 Methods of costing
- By Elements
- By Modules
- My Trades and Works
- By Volume and Area
Draw the Sceme of approximate cost estimate via volume and area
What percentage is the building cost approximately relative to the total production cost?
Building Cost ca. 90% of the Production cost.
Given the following Reference Building Costs and Index. With an current Index of 111.3. Estimate the Building Cost for today.
