Using standard contracts: I'm looking into the use of standard contracts for services (such as borehole drilling, building toilets, laying pipes) and finding very little information. Are there any publications lurking out there?

There is no as such 'standard contract for well drilling', but you can use FIDIC red book, standard contract for construction and customize it.

Hi Brian - we have the harmonized conditions of contract for the WASH sector released in nov 2020 on the IHIP website:

http://www.ihip.earth/harmonized-particular-conditions-of-contract-for-construction-for-the-wash-sector/29

But I guess you are looking for more specific services?

Let me know if you find any - it might be of interest to consider how they can fit in the IHIP approach as well.

Best,

François
