How to Prepare a Construction Schedule?
(OP)
I work on a lot of roadway widening / rehabilition projects for various cities. I alway have a difficult time estimating how long the construction schedule should take. Mostly I estimate it by using previous projects but I don't have any back up to support my duration. Does anyone know of a book (or anything else) that lays out typical durations for typical steps of construction of construction?

If you are an engineer and you are doing estimates for time, I would certainly couch that as an opinion rather than an estimate...it carries less of a requirement for accuracy than an "estimate".

This makes difficult that whatever your guess one can be extremely precise about the duration when soil, means, budget, primes and everything that makes the timeframe be affected has significant say. If money is available as thought, and no uncertainties were extant, it would be only to sum the compatible time use of a number of means assumed in the project. But that still would be assumption.
Seen otherwise, perhaps priming is one interesting way of approximating the timeframe to some wanted; the contractor would have incentive to allocate means enough to approach the timeframe, and conversely, the more suitable contractors to the work would be more interested in it because knowing their advantage, they can think on the incentive both as a partial assurance to get the contract and as well, of keeping some minimum benefit, and so would make the bidding process more selective from a target date viewpoint.

Another way of making a "back of the envelope" estimate is based on dollars/time. How long did the last project take vs how much did it cost? Very crude indeed, but it is a way of making a quick estimate. Then you can adjust based on the variables of the particular project.
