Extreme Example of Jobsite Coordination

The jobsite coordination shown in this example is an extreme because of all the different trades involved. This manhole is one of many and a small part of the entire project. Nevertheless, this type of production was the norm.

The crew did not have any training for this type of jobsite coordination it was only repetition. Whatever type of construction you may be involved with around your home I doubt you would ever be in competition with this type of coordination. This example demonstrates the power of extreme coordination for a small part of the project.

The cost for the contractor’s client to change any part of the construction after it starts would be very expensive for the contractor. The client would be liable to pay all the costs for any change. This also would be true for any home project if you were to change anything that would interfere with the contractor.


Jobsite Coordination - Field Cast Manhole

-

Here is an example of jobsite coordination to field cast a manhole:

• Day 1 we excavate and haul away the material. Sheath the excavation for safety and ease of construction. The iron-worker sets the rebar for the floor. The carpenter with the laborers pours and finishes the concrete floor.

• Day 2 the iron-worker sets the rebar for the walls while the carpenter and laborers ready the forms. When the iron-worker completes the rebar for the walls, the carpenter and laborers set the forms so the finished concrete will be the inside dimensions of the manhole. When the walls forms are set, the roof form is set. A special metal form sits on the roof of the manhole to allow for the required 36” diameter access opening through the concrete roof. We pour concrete between the manhole form and the sheathing for the walls and then the roof is last with the rebar.

• Day 3 we let the concrete cure.

• Day 4 the laborers strip the manhole inside forms and outside sheathing then the bricklayer places the neck on the manhole until the casting can be set level with the surface grade.

This is an example of a well-organized crew who has prepared the materials in advance. The iron-worker has cut and bent the rebar to specification, the carpenter has the necessary forms and materials ready for installation and the different trades work together in a coordinated effort.

This is an extreme example of jobsite coordination.


Contractor Experience = Cost Savings

Costs for this field cast manhole were lower after we had completed several with the same crew. Size of the manhole did not matter since the iron-worker can easily cut and bend a little more rebar and the carpenter may easily fabricate more forms.

Homeowners will also realize cost savings for GREEN renovations when the contractors become more familiar with the materials through repetition of installations. Jobsite coordination and flow leads to your cost savings. This is the reason you have to know the contractor’s experience with your type of GREEN renovation.
