Project Management - Open Project.

Technically, I think I failed to use this application. Link below is my open project file.

Rob Shaw 550 Open Project

Here are some reasons why I think I failed to use the application.

1st. MH(Men Hour) & PH(Physical Hour)
Men Hours is used for the job which can be done within a hour with one men power.(Resource - Men power). So if you could allocate more men power to the job, then the job will be done more quickly. For example, if frame joining job is 12MH job, then, it can be done within 12hours by one worker. But if we allocate 3 people on the job, then it can be done within 4hours. So, this is Men Hours.

Physical Hour is a lot different concept. No matter how many resources(Mainly men power) you allocate, job can't be done quickly. For example, steaming stripped plank for laminating, glassing resin hardening time can't be shortened with more men power.(If you could allocate different kind of resources like cooking bay, heater, high powered steamer, it could be shortened, but it still takes time)

And while I am using this application I couldn't differentiate and express these MH, PH and other resources which could affect the job schedule.(Before, I just used combination of MS Excel and PowerPoint for this).

2.I failed to allocate resources - Men Power.
Virtually men power is the only effective resources for the task. So while A, B, C resources are allocated to a certain job, then, these resources can't be allocated to another job at the same time. I couldn't even compose resources table.

So these are the main reasons that I think I failed to complete this PM application.
All you could get from the file is a list of Job & Task and its co-relation.
And this file doesn't show real progress that we built Rob Shaw 550, I composed it, thinking that if we build the boat again, how is it gonna be basis.

Thank you

Small Craft Building - 4.Flip Over and Interior

When hull's done, it's time to flip over the boat and start working on its inside.

Before we flip over the boat  we need to make sure that all screws or nails to frames through the hull need to be pulled out and all sticky things removed.

And also mark the bulkhead position on hull, just because we didn't do it, we had extra trouble in installing bulkhead at bow.

When all the thing is done, slightly lift up the hull and try to find where it's stuck to. In case of our boat, bulkhead was stuck to the frame due to excess glue. So we had to remove the hull with temporary bulkhead frame on it from the hull.

When boat is flipped, then, move B/H forward and after then, it will be easily removed..


1.B/H
Since we didn't mark the position of B/H, we need to measure where it will be at sheer and from here using level, we marked its position on the hull.

Once its position is fixed, we cut out the B/H and its cover from plywood and B/H itself.
And we fixed B/H with clamp and wood block to maintain its exact position and make it plumb.


2.Fore Deck
For fore deck, we made fore deck rest laminated with plywood and fixed it right forward face of B/H. Also as a fore deck rest, we made short inner gunwale too.

Then we cut out and scarf jointed fore deck we couldn't attach it to the position.



3. Quarter knees
We made it laminated and attached it to the hull

4. Thwarts
We made 3 thwarts but unfortunately we couldn't attach it to the hull.
