EBI Consulting vs Partner Engineering and Science (Partner ESI)

Environmental and engineering due diligence — Phase I/II ESA, PCA — founded 1989, top-3 US CRE due diligence provider

A go-to for lenders and acquirers who need Phase I/II ESA or PCA reports from a top-3, decades-established provider — founded 1989, with the track record that lender due diligence checklists often implicitly expect. Like AEI, this is a professional services relationship, not software, so evaluate on local coverage, turnaround time, and report quality rather than platform features; pricing is deal-by-deal and not something you'll find published.

National Phase I/II ESA, PCA, zoning compliance, and seismic due diligence provider — rated #1 environmental due diligence provider in the US

Buyer: lenders, investors, and acquirers needing environmental and property condition due diligence reports -- Phase I/II ESAs, PCAs, seismic -- for an active transaction, especially where speed and defensibility matter for closing. Strength: a top-rated national provider in a fragmented, quality-variable industry, which meaningfully lowers the risk of a bad diligence report. Caveat: this is a services firm, not software -- pricing is quoted deal-by-deal, so build lead time into your due diligence timeline rather than expecting instant turnaround.
