[Site Stage Scheduling] Pile Cap and Tie Beam

10/18/2016 11:47 AM

Hi there,

I am a building engineering student and here looking for some experience in pile group construction. There are 3 group of pie caps and tie beam (with attached) in my assignment, I need to design the stage schedule and consider some factors that may impact the construction work. The former is the most difficult part for me, as I have no experience in forming site stage schedule.

I did some researches before I am here asking for help. However, I cont find efficient information to build up the schedule. Could you guys please share some of yours site experience in constructing pile cap and tie beam to me?

Here are some of my questions:

>Site planing

1. How many space i need to reserve for material yard?

2. Any crane need to use in this project?

3. How many labor should be assigned for this project?

4. How many concrete mixer need to be arranged?

5. How many m^3 of earth can a excavator dig per hour?

>Scheduling (duration of different stage)

1. How long for labor to construct formwork for filling concrete?

2. I think there are 4 main stage:

3.1 excavating of earth

3.2 installation of formwork

3.3 placing reinforcement

3.4 filling concrete

Is that correct? How many time for each stage??

What are you guys opinions for this project? How would you guys design the construction schedule? and why??

Sorry for the basic English, poor me ;P

Have a nice day and thanks! ^^

I wonder how I ever became an engineer without the Internet.

Before they had the internet, they had the study net.

Thanks!

It helps.

Do you have any experience for the construction site?

How many workers it may takes in this project??

No!

Do your own homework.

Don't ask others to do it for you!

You have textbooks containing all of the information needed to answer your questions.

Why are you coming here to get the answers?

It's called "resource management". He's having a go at that.

Hi

All of my lecture notes hasn't contained the information I needed , say, it hasn't stated any project case for how many labor are required or how long to build a temp-formwork and that why I am here.

I do understand your situation...experience helps answer this type of question...if you don't get any reasonable responses I'd try and make reasonable engineering assumptions. I remember when I was at uni the first page of any exam had the line (something like this) "If necessary, make reasonable engineering assumptions". I took that on board and helped me get through...

As an example, If i knew that the part answer was meant to be a 1 or zero but got some ridiculous figure, I'd put a line under that answer and say that I know this answer is wrong and due to exam time constraints I cannot go back to work out where it went wrong, I will make an engineering assumption that I got 1 or zero and continue. That way the examiner knows I know that the part answer is wrong and I can show that I can continue on - as opposed to some colleges that just continued with a wrong answer and got much lower marks.

That said, In your case without the experience, I'd say why I chose the number of laborers for the task. What you need to calculate is how many man-hours you think may be required to complete the task (and why). From there it's easy. How many work hours a person works (calculate at say 80% efficiency) per day. Consider work days per week, public holidays and each persons holiday and sick entitlements (this is calculated from 1 year but broken down to days) - At my workplace, with the amount of personnel, I've calculated that one person will be away at any one day for the whole year - this has to be factored. This gives you worst case scenario. If you then know the project completion time-frame, you quickly can work out how many people are required to complete the job.

I hope this helps somewhat. It's not 'everything' by all means (tools available per person, supplier schedules and lead times, weather, workplace accidents, etc).

What would really help you would be to spend a month or 2 getting dirty on a building site learning how things get done, your answers would be easy then..

I agree! One picture worth 1000 words.

1 week on the job,down in the trenches is worth 1000 hours of classroom study.

Theory is good.Proper engineering is essential.

Hands on experience allows you to see how the rules are applied in real life situations,and drives home the lessons learned in class,and somehow,allows you to intuit a valid design before committing it to paper,or computer,as the case may be.

Do your own homework.

There is as much to be gained from the commitment as there is from the completion of a task.

Get some experience in "forming site stage schedule".

Good luck!

Two guys and a pile-driver-equipped barge crane for about a week, with all the stuff on the barge rather than stored on land. [??]

You can't really pity the next generation. It's not entirely their fault.

I like doing linear equations, it's about the only type of math I enjoy, in my work I need to do geometry also, but I don't really enjoy it.

I decided that maybe I could use a refresher course in mathematics, so I went to the local community college, I found out that almost every math class they offered was via the Internet. You paid a fee, got an access code and did all of the coursework on you p/c or laptop, then a virtual teacher would grade it.

When I was in high school, you could take a math class and if you understood or didn't understand a problem, a real live human being could explain why or how the equation worked and they would show an example of the math and how it was used in an industrial field.

And schools would have field trips. Not anymore. Now it's just number crunching for the sake of number crunching, no examples, no Class rooms, no teacher interaction, no student groups.

About the only thing left is a resource room, where student aides, often only given several minutes allotment, can work with a student, once a day, to help them understand how to do the equation.

The only class available that was in a real class room setting was basic math.

I asked why this was so, they told me it had to do with budget cuts, it wasn't because there were more students or less teachers, it was because more monies were going to fund social service programs that were unrelated to the public educational institution.
