Room Additions – Construction Task Timing
Estimated Time To Complete Specific Tasks
The following is a listing of many planning and construction aspects that are involved in the construction of a typical room addition. If you plan to tackle a room addition project you will be involved in virtually all of the following tasks in one way or another.
I've taken the liberty to group some tasks together and others are broken down into sub groups. There are actually hundreds of individual "things" that have to be done.
Average Times
I researched my past records and averaged the times. Not all room additions are alike. The times shown below are for a 400 square foot single story addition with moderate access.

This means materials have to be hand carried from the front of the house to the rear. The below estimations also include a close approximation of the man/woman hours it may take to complete the listed task.
First Timers
If you plan to do things for the first time, be sure to add additional time. Your room addition project may not include some of the listed tasks. If it doesn't, be sure to substitute things that may take the place of a listed task. You will be surprised how time seems to disappear each day.
The numbers also include the amount of time it takes to estimate, order, pickup, transport, and unload the necessary materials. This running time can be enormous.

Thinking Time
Don't forget to include "thinking" time. What is this? This is when you will stop all work and scratch your head wondering if you are doing something right.
It happens on all jobs. Sometimes it may take an hour or two to determine the best way to solve a problem. This isn't wasted time, just "thought" time!
