The following are my top data sources for construction cost estimating. I use them successfully in my detail, or conceptual cost estimating. They apply to most of the construction markets, from buildings to many types of industrial and infrastructure projects. Of course, nothing beats the actual cost data that we collect from completed projects. Well, unless you work for a company that has a rich feed of data from the field, you will find yourself in a position to reach to outside resources.
- John S. Page Estimating Manuals. Excellent resource for activity based production rates. All these books are available in print format from Barnes & Noble and Amazon.
- Estimator’s Equipment Installation Man-Hour Manual
- Estimator’s Piping Man-Hour Manual
- Estimator’s General Construction Man-hour Manual
- Cost Estimating Manual for Pipelines and Marine Structures
- Estimator’s Man-Hour Manual on Heating, Air Conditioning, Ventilating, and Plumbing
- Conceptual Cost Estimating Manual
- Estimator’s General Construction Man-hour Manual
- Estimator’s Electrical Man-Hour Manual
- RS Means Yearly Cost Data Books. A great resource for construction cost data. While the costs apply to the US market, with some Canadian coverage, it is still a great resource for crew composition and production rates. The books are available for sale on the RS Means website, http://www.rsmeans.com.
- Compass International Yearly Cost Data Books. A great resource for international cost data, covering over 120 countries on industrial and commercial projects. Books are available on the company website, https://www.compassinternational.net/construction-estimating-yearbooks/
- Design Cost Data Magazine. A great resource for preliminary cost estimating and data modeling. Cost data applies to the North America. Through the subscription on their website, one can have access to a large database of historical data in building construction. Visit them at http://www.dcd.com.
- The Chief Estimator Software (http://www.infrastructurecost.com/Cost_Data). Even though this is a cost estimating software, with the option to buy the cost database, I could not miss this from the list. The database that integrates with the software is impressive, to say the least. It has comprehensive task, crew, labour, equipment and material databases for a large array of infrastructure and industrial projects. It makes cost estimating a breeze once you learn how to navigate around the software. The database, like any other live resource, needs maintenance if you want to produce accurate and up-to-date construction costs.
- For cost trends and indexes, I always turn to Engineering News-Record, http://www.enr.com.
All these are paid resources and can cost in the thousands of dollars; I find them worth the price. For those instances when I need access to reliable data I am glad I have them.
I hope you will find this information useful. If you have any resources that you would like to share with the rest of us, please leave a comment. It will be much appreciated!
I like what your doing here, please put me on your mailing list.

It’s really interesting and instructive what you do with this blog. Please keep me postef
Alex, thank you so much for your comments. I am really hoping that this site will build a community of cost estimators to exchange ideas and knowledge. The Q&A Forum page is a great place to ask/answer questions related to cost estimating.

I use SPON’S FABRICATION NORMS FOR OFFSHORE STRUCTURES. Do you have experience with these norms?

Hi Jan, thank you very much for the tip. I did not know of this book. I see that it is available on Amazon. I will add it to my collection.

Donia I appreciate for your positive step towards “spreading the light of knowledge” and providing a platform for all the professionals and as well as students.
Ahmad, thank you!
Very good post and very useful! Do you know about any free database for labor productivity in civil industry? If yes, I would be very happy to know about that.
Hi Dima, sorry for the late response. I researched to the best of my abilities, and I could not find any free man-hour data for the civil industry. Even the paid resources are not very abundant and detailed, like for example the process industry which is covered by all major construction cost data sources in great detail.
I have been a welder for 30 years. I want to get into estimating I recently passed my Oklahoma Mechanical Contractor exam, I’m in Need of cost estimating , I have looking at buying john s Paige, conceptual cost estimating manual, piping man hour , and equipment installation
Hi Cole,
Congratulations on passing the Oklahoma Mechanical Contractor exam. Yes, John’s Paige cost estimating manuals are great. They give you a good perspective and starting point for manhour estimating. It does not cover the equipment requirements. But, regardless, I am a big fan of all his books.
Hi Cole,
Congratulations on passing the Mechanical Contractor’s exam!
I like John’s Page manhour estimating books. They are great for understanding production rates in manhours. What type of projects would you be interested to learn how to estimate? Would you be a subcontractor bidding to a general contractor, or would you bid on projects as a general contractor? With your extensive welding experience I am sure that you know the trade in and out. All you need to learn is some techincalities of how to put the cost together. Let me know some specifics about the projects and I could point you in the rigth direction.
Regards,
Doina
