How many bosses do you have when you work in matrix organization?
2
OBS:
what does it stand for (abbreviation & explanation)
Organizational breakdown structure
Project team that will make the project. (includes communication channel, authoritiy & responsibility)
What are the downsides of a functional structure?
What aspects do you have to consider when selecting an organizational structure?
What are the objectives of a WBS?
-Abbreviation
Work breakdown structure
-Reflect your scope
-Organize the activities to do in a project
A WB (work package) can be (4 Dinge).
Monitored
Controlled
Scheduled
Estimated
DOW
Division of Work:
Put the WB (working packages) to the responsible member who is responsible for that (organization units)
RAM (abbreviation and explanation)
Responsibility Assignement Matrix
Whoch member is responisble for what (primary & secondary responsibility)
(zusammengesetzt aus OBS (organizational breakdown structure) & WBS)
A responsibility assignement matrix defines...
A work breakdown structure reflects...
A organizational break describes...
...the roles of the team members
...everything needed for a project
...the project team

Elements of a contracting strategy:
Administrative strategy
Type of contract
Project delivery system
Type of schedule
Project delivery systems:
1. Design-Bid-Build (design & bid-build sind nicht vom gleichen Unternehmen)
a. Construction Management at risk
b. Multi-Prime (owner is the general contractor und schaut für budget & schedule)
2. Design-Build (design build by one entity)
3. Public private Partnership (PPP or P3)
4.Integrated project delivers (IPD)
Bidding process consists of:
1.Announcemnent (Ankündigung)
2. Preparation & Submission
3. Evaluation & Selection
Bid types (4):
Open bid: all
Restricted bid: not all
Selective / Inviation bid: eingeladene
Direct awarding
(depens on the project volume and market situation)
What are the different types of negotiated cost plus contracts?
Fixed fee
Sliding fee
% of cost
GMP
What does IPD (integrated project delivery system) prevent?
Litigation
Competition
equation for WBS
WBS = PBS + ABS
What are the components of claim?
Time & money
What ist the most common activity realtion in construction project?
Finish to start
What are the steps to create a schedule (4)
1. Definie activities
2. Sequence activities
3. Determine duration
4. Graphical representation
Gant chart:
horizontal axis
vertical axis
Gant charts are.
-hor: time intervalls
-ver: tasks to be performed
-type of bar illustrating the project schedule
Excusable delay
beyond contractors control, like unforseeable weather, owner change and different site conditions
can be compensable (owner ist schuld) or non-compensable
hurricane is an example for:...
...force majeure
Pacing characteristics.
(Contractor does smt to pace the proces)
Voluntary
By-product of concurrent delays
Liquidated damages
They are not a penalty, they are set in the contract phase.
Calculated loss what the owner will lose if the contractor is over schedule
Method to determine durations:
-Stochatic method
-PERT
-deterministic (most common)
Acitivity duration
Duration
Effort
-time calendar unit between start and finisch
-total numer of work periods (workdays/workweeks) -->nur Arbeitstage
-The number of units needed to complete an activity (staff hours/days...)
FF (free float)
TF (total float)
-time which an activity kann geschoben werden, without a delay of any other activity or end date
-time which an activity can be moved/extended without a change in the end date
Finish to start
Start to finish
Start to start
Finish to finish
-
-an acitivity can be finished erst wenn die nächste gestartet ist (special case)

Estimate types:
detailed estimating
Parametric estimate: durchführbarkeit (feasability)
Bid estimate: detailed
Contract estimate: detailled, most accurated & binding
detailed: based on quantity of each task
Parametric estimation characteristics (4)
-for go/nogo-decisions
-scalable (2h für 3000Wörter daraus folgt 1h für 1500 Wörter)
-uses historical datas
-fast and not much effort
auf das Projektvolumen wird geschaut
sehr ungenau, kann nicht days of work angeben
detailed estimation
direct cost + indirect costs + markup
markup = profit(company needs) & financial risk(market needs)
direct costs (4)
Labor
Material
Equipment
Crew
indirect costs
Nicht einem Projekt/activity zuordbar:
main offices
company car
...
Resource leveling:
Resource smoothing:
-Leveling: Resource constraint. The Aim is that the resource limit is not exceeded. Extend of the project duration possible. Nur wenn die Ressourcen bei einem Projekt limitiert sind.
-Smoothing: Time constraint, the finish date is fix and it's tried to rearrange the task so that as less ressources as possible are needed. Only free resp. total float is used.
What is essential to develop reliable estimates?
-Experience
-Qualitiy
Which of these are main objectives in ressources management?
- save money
- reduce downtime
- rent less equipment
- have less workers
- prevent overallocation
prevent overallocation
reduce downtime
BCWS
budget cost of work scheduled (planned value)--> wie weit man geplant hat zu sein
ACWS
Actaul cost of work performed (actual cost)-_> wieviel dafür gezahlt wird
BCWP
BAC
Budgeted cost of work performed (Earned value)
BAC: Budget at completion
Schedule variance:
Schedule performed index:
Cost variance
Cost performance index:
Schedule variance SV = EV - PV
SPI SPI = EV / PV
Cost variance CV = EV - AC
CPI CPI = EV / AC
