I am doing a project management class and I need to know how about how much days these individual step take approximately….
Site clearing -
Removal of trees-
General excavation-
Grading general area-
Foundation construction-
Excavation for utility trenches-
Placing formwork and reinforcement for concrete-
Installing sewer lines-
Installing other utilities-
Pouring concrete-
Excavate trench-
Place formwork-
Place reinforcing-
Ok, First of all, some of the tasks are categories and some are sub categories…
1) Site Clearing includes tree removal, general excavation (and fill if necessary), trenching, and general Grading, possibly basic excavation for utilities. Count on at least 4 days in summer and good weather… Allow two days for rain… Most of these tasks will run concurrently, not consecutively…
2) Foundation construction will include the rest of the list… Depending on the size of the structure, count on 3 days for a typical house and pour concrete on the fourth day…
Again most of the tasks will run concurrently…
This comes from my experience with several Cement finishers… A good team will be cleaning up the area on the fourth evening… They will usually return about a week later to break out the forms…
Final utility installation will be last… That is installing a service pole and turning on the elec for the framing crews… Water/sewer will be at the very end of the job… usually just before landscaping…
But for the sake of each individual task here is what I would estimate;
Site clearing – 2 days with heavy equipment
Removal of trees- dependent on how many and size of the trees 2 days
General excavation- 2 days
Grading general area- 1 day
Foundation construction- 4 days
Excavation for utility trenches- 1 day
Placing formwork and reinforcement for concrete- 2 days
Installing sewer lines- 1 day
Installing other utilities- 1 day
Pouring concrete- Must be done in start to finish in one day, because once pouring starts it can’t be stopped and restarted
Excavate trench- 1 day
Place formwork- 2 days
Place reinforcing- 1 day (usually a good team of rod busters will have the reinforcement complete by just after lunch… on the 3rd day… They may have the Rebar and mesh ready before the forms are completed, if so then they will want to start placing them as soon as the formsetters are out of the way…
This applies to a typical house foundation, and you should allow a little more time for a larger structure… But typically a larger building project would just have more workers…
Hope this helps
