Most contracts with
subcontractors can be fairly simple and straightforward.
The key to good scheduling is communication and
knowing the sequence of events. There are two types
of tasks, critical and non-critical.
Critical tasks are those task that determine the
length of the project. If a critical task is delayed,
the next task cannot start and the time for completion
is also delayed.
Non-critical tasks are task which have some leeway,
so that they can take longer than expected an still
not hold up the process. A non-critical task can
turn into a critical task if it takes a lot longer
to complete than expected.
Most subs are very busy and need to know a general
idea when they will be needed on the job. Construction
superintendents notify their subs when they are
4 weeks out, 2 weeks out, 1 week out and then a
couple of days out. In order to keep their employees
scheduled efficiently subs must know your schedule
and be updated regularly. If you get the subs to
the site early they will lose money (and be frustrated).
If you get them there late you add time to your
project. If that task is a non-critical task timing
is not as critical. You have some leeway as to when
the sub begins. Our professional construction schedule
shows the the critical path timeline and how critical
and non-critical tasks are interrelated.
A simple contract is better than a verbal agreement.
It can save time, money and disputes.
Scheduling mistakes often cause extra details. For
example, If you schedule the plumbers to do finish
plumbing before the kitchen countertops are installed,
they can do finish most of the job except for the
kitchen sink. What if their next available opening
is 2 weeks out? You may have to do it yourself or
pay another plumber to install it.
