Concrete Testing Lab at the site

Hi guys,

I've been asked to look for pricing for a concrete testing lab we're going to have on site at a highway my company is building.

Items I'm supposed to price include:

a concrete breaker
2 spacers (one 4" and one 6")
12 sets of spacer pads for the 4" spacer
12 sets of spacer pads for the 6" spacer
2 curing tanks
2 heaters (1 for each curing tank)

I'm having trouble finding any information on the spacers and the pads that go with them. Any ideas as to where I could look for this?

Thanks!
