Using ScheduleReader in STOs?

ScheduleReader™ is a software for viewing schedules exported from Primavera in the XER, XML and XLS file format. 

It can convey schedule information through dynamic views among all parties involved in a project, enabling them to easily interact with the (view-only) data by using filters, groups, sorts, reports and more.

Turnaround schedule levels

In various literature I see two different kind of schedule levels. Level 0-4 or Level 1-5.

Which definition is commonly used ?

What would be the appropriate levels for a turnaround schedule and could someone give me some specific examples for a turnaround of each level ? (duration 2,5 weeks, 2500 mechanical hours)

Resource Linking - good/bad?

I'm kicking off the planning of a 200,000 hr shutdown due in 12 months. Previous shut downs here have used extensive resource logic between physically unrelated activities as a way of manually resources.

I'm not a fan of resource linking, I'd rather use the automatic resource leveling and let any unrelated activies sit on data date if they are available for work to start.

I can see there are pros and cons for both methods, udateing with resource links can be a nightmare with work all over the place and possibly/most likely incorrect critical paths poping up at every update.

Calculated time vs duration

I have for example a safety valve which has to be replaced and calculated the disassembly and assembly time for example to be 2 hours.

My colleague scheduler says he always sets the duration for this activity to 10 hours (in this case the length of a shift), because he is only interested in the fact that the work on the safety valve is done on a specific day during this shift and not exactly in which 2 hours it is done.

Is this good practice ? Why ? (or why not)

Regular Maintenance vs. Turnaround Maintenance Cost

Hi:

I have been looking for some benchmark data or research to try and put numbers to costs associated with doing work during Turnaround (TAR) versus doing it as a normally scheduled maintenance task (OR OUTAGE) carried out by either in-house maintenance crew, or external contractors.

I thought there would be more information available online about this area, but have been unable to find anything specific.

Characteristics for Turnaround projects

Hi everybody,

Maybe a good question to start with in this forum:

What are the characteristics specific for Turnaroundprojects ? (what is fundamentally different compared to a "normal" construction project for example)

Which things do you encounter which you will only see in those kind of projects ?

New to Maintenance/ Shutdown scheduling

Hi, my experience has always been project planning.  Recently I've been assigned to do maintenance/ shutdown scheduling (CPF, well pads), I'm having a hard time figuring out how to approach it.  In projects world, I've always been doing the top down bottom up approach.  For maintenance/ shutdown, so far my observation is, everyone is in the weeds.  Just to list a couple questions to start off:

1) There are 9 levels in the WBS, with every single WO in it.  Is there a simpler way to do this?  Can the WOs be activity codes?

2) In general, what's th
