# How high is the production bonus of a great engineer in Civ5?

To quote the manual:

Special Ability: Hurry Production

You can expend a Great Engineer to create a sudden burst of production in a city. The production is immediately applied to whatever is presently being built in the city – unit, building or Wonder. This will usually be enough production to immediately finish all but the most massive Wonders, and it will drastically shorten their production time.

I had a great engineer during modern times, and using it to help produce the Statue of Liberty (1200 prod needed) yielded 750 production. Letting it help along for a Stock Exchange immediately finished this building (650 prod cost).

I assume that the amount of prod. generated is somehow game-stage related? Are there any known specific rules?

I'd say its also game speed related since all the build times are scaled – Eric Oct 26 '10 at 21:45
I was guessing this would be in one of the XML files, but I couldn't find it. – bwarner Oct 27 '10 at 1:36

The amount of production of a great engineer on normal speed is calculated using the formula

``````300 + 30 * city population
``````

So in a city with a population of 1 the engineer only results in 330 production, in a size 15 it results in 750 production.

For quick speed the formula is:

``````200 + 20 * city population
``````

For epic speed it is:

``````450 + 45 * city population
``````

and for marathon it is:

``````900 + 90 * city population
``````

The amount of hammers does not seem to be influenced by era, map size or difficulty level.

Conclusion: If you want to hurry late game wonders, build it in a city with a large population.

Cool! Where did you get the numbers from? – Martin Oct 29 '10 at 20:24
I played around with Firetuner. Took me a bit to realize that population plays a role. I always got 330 hammers and wondered why this was different from the 750 in the question. – Mad Scientist Oct 29 '10 at 20:47
