(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Hi,

How is the floor cycle duration of high rise building determined?

Dear Sirs,

 

can anyone give me sample of high rise building program in Primavera, I dont have much experience in such project.

besides Im a new User in P6. only 2 years. 

 

Thanks!

Yes i Agree with Arman,

Normally high rise building cycle varies from 7 to 9 days per floor, again depends the availability of tower cranE.

Kier,

1 mh/sm for table form seemed ok but for beam u may use 2 mh/sm. It is already a fast rate...

Tower crane availability highly dictates cycle time especially if MEPF, Architectural and balance of your structural works are already progressing in parallel. So you have to make sure that your intended cycle time goes along with the total tower crane hours availability.

Regards,

Arman

Hi Arman,

Thanks a lot for the info,

Please confirm if my productivity rate for formworks are correct.

table forms for beam and slab =1mhr/sm
Wall and column forms= 2 mhr/sm

Does anybody know how crane analysis is done.Do I have to consider the load of tower crane for 1 floor.Does the cycle time dictates the number of tower crane?

Regards,

kier

Kier,

I would like to suggest the following:

considerations:
1. Podium level not included;
2. 2 to 3 sets table and beams forms;
3. 2 sets column and shear wall forms;
4. 1 to 2 sets re-shoring;
5. Slab design with beams (not flat slab);
6. 1 Tower Crane;
7. 1 to 2 units man lift (fast car);

Working hours:

Structural Workers: 7:00 start
MEPF Workers: 7:30 start

cycle time:

7 to 9 days per floor (slab with beams)
5 to 6 days per floor (flat slab)

notes:

1. The number and type of form sets highly dictates the speed of structural construction per floor. It is very important to know what is being considered in the tender programme as it is expensive.
2. Other factors that have to be considered:
2.1 Materials and Manpower Movement;
2.2 Tower Crane Analysis;
2.3 Construction Lifts Analysis;
3. Discuss with Forms and Scaffolding teams or supplier regarding rates of progress.
4. Wet weather


I hope that the above may make sense to you. I also hope that others may contribute or comment.

Best regards,

Arman

Dear Kier,

You need to determine the method of construction of the vertical elements and the slabs.

Usually for high rise you have self-climbing formwork like the one from Doka. See link

http://www.doka.com/doka/en_global/whatsnew/news/pages/05631/index.php

Subsequently, you can determine the floor cycle.

Best,

Samer

it can be determined by making a plan or schedule.
