Cost Estimating and Tricks of the Trade - A Practical Approach
Kolmetz Handbook of Process Equipment Design - General Process Plant Cost Estimating
The Gross & Associates Rules of Thumb brochure was a handy wealth of information long before the Googles and the Chats and the GPT's took over everything.
This Rules of Thumb brochure was published in 2010 after TranSystems acquired Gross & Associates in 2008. At the time they were proud to continue the tradition, possibly because it was already written and still fairly up-to-date. I don't know that they've published another in the past 15 years. If you find a more recent version, send it to me!The costing estimates are no longer quite applicable except as a frame of reference and order of magnitude, but the handbook provides a relevant glimpse into production layout & lighting recommendations, square footage norms, forklift aisles, pallet & racking calculations, and a ton of still-relevant and useful industrial insights.

Practically there is no reason why something should be on your floor for 8 weeks, let alone 8 months. Quoting 50 weeks lead time and missing by 2.5 months weeks isn't a sign that you're a great salesman with a healthy backlog; it's a sign that you have a momentary monopoly in your sector, a choke point instead of a factory, and hey, everybody's just used to drowning in WIP because that's the way it's been ever since ___________ . Whatever!
