Most Technical Due Diligence is shallow, slow, or split across handoffs that lose information in transit. We do it with one cross-disciplinary team in-house - engineering, data, financial, regulatory - under one project lead, with the full ROI math built in. Buyer-side or seller-side. Pre or post-transaction.
Both worlds, one team. Talk to us before you sign.
Different asset classes. Different jurisdictions. Different deal sizes. Same four technical-diligence risks - every single deal we are brought into. Here is what they look like, and how to surface them before the numbers start to wobble.
Seller-side Technical Due Diligence exists to support the deal, not to undermine it. The good ones are honest but incomplete; the less good ones are selectively framed. Even when thorough, the seller is not going to commission an investigation into the things that would lower their price. Relying on it without independent verification catches a lot of deal teams.
Most Technical Due Diligence covers the visible: structure, envelope, mechanical condition, statutory compliance. What it misses sits one layer deeper - data infrastructure, metering setup, smart-building readiness, regulatory cost from EU EED 2027, EPC, and CRREM stranding risk. These show up in year two, when the building under-performs the numbers you put in your offer.
Every building in the EU stock is heading toward a meter retrofit by 2027, and most acquisition models do not price it in. Found during diligence, the exposure is a price negotiation lever. Found after closing, it becomes a write-down - and a cost the Operations team takes on during the hold period.
The big property consultancies and Big 4 advisory practices run multi-team: mechanical, electrical, sustainability, financial, regulatory each in a separate specialist group. Findings get handed from team to team, summarized by a project manager who was not in any of the original investigations. Information loss is built in. So is the cost. So is the time. The findings that change the deal sit at the intersection of two domains - exactly the ones that get summarized away in the handoffs.
Deal teams use NorthQ primarily for Technical Due Diligence and the ROI math that goes with it - that is the Consultancy pillar. The Technical Due Diligence already includes the baseline and the action plan for what to do after closing. If the buyer wants us to implement that action plan, the Operations services pick it up. Data is the foundation underneath, made portable and vendor-neutral by our Open CTS/BMS layer - so the asset stays yours, not the incumbent's.
The data foundation underneath both. Vendor-neutral, EU EED 9c compliant, ready for whoever operates the building post-close.
Implementation of the Technical Due Diligence action plan. Energy optimization and the ongoing operational services.
Technical Due Diligence with ROI math. The heaviest engagement during a transaction. One cross-disciplinary team in-house, one project lead.
The layer that reveals what a traditional TDD misses - because it is the layer traditional CTS/BMS was built to hide.
Where NorthQ engages depends on where you are in the deal. The work is different at each stage; the team is the same.
Before the letter of intent is signed, the numbers are still flexible. The cheapest stage to surface technical risk and ROI upside: regulatory cost exposure, smart-building readiness gaps, optimization potential. We deliver a focused snapshot - usually one asset, scoped to the questions that change the offer.
Once the letter of intent is signed, the On-site Inspection Report runs - typically over about a month. Buyer-side, seller-side, or both. The deliverable is a defensible package with full ROI math, covering technical, data, regulatory cost, and smart-building dimensions. One project lead, one team, one consolidated report - plus an executive summary for the deal team and the investment team.
The first 90 days are when the numbers in your offer either get validated or quietly start to drift. We hand over a clean action plan - already part of the Technical Due Diligence - and the same team can implement it if you want them to.
Some of our most useful engagements happen after a deal has closed. Buyers who used another provider, or relied on the seller's report - they bring us in afterwards to find out what they actually bought. The work is similar to Stage 3, framed as "tell us what we did not know we were buying."
Most deal teams already have a Technical Due Diligence provider - a major property consultancy or Big 4 firm. They cover the right ground; what changes with NorthQ is how. Their teams sit in separate practices, with findings translated through project managers who never saw the buildings. The output is fine. The cost is high. The speed is slow. Accuracy degrades through every handoff.
So here are the four structural differences:
Engineering, data, financial, and regulatory expertise sits in-house at NorthQ - one project lead, one accountable team end-to-end. No handoffs, no information loss in transit, no project manager translating between specialists who never spoke to each other. The findings you read are written by the people who actually did the investigation.
Most Technical Due Diligence findings sit at the intersection of domains: a metering decision implies a regulatory cost implies a CAPEX adjustment implies a change in your business case. Specialist teams in separate practices find each piece separately and lose the connection. We find them together because the same people work the whole picture.
Every NorthQ Technical Due Diligence comes with the numbers: investment required, returns, payback, recommended price adjustment, prioritized action plan. The findings tell you what is there. The ROI math tells you what to do about it. Generic reports often stop at the first half.
Some of our most useful engagements happen after a deal has closed: buyers who used another provider, or relied on the seller's report - they bring us in afterwards to assess what they actually bought. We find things the original diligence missed. Enough times that buyers now sometimes engage us post-close on principle, regardless of who did the pre-close work.
Worth naming so this page is not all promise:
Whether you are pre-letter-of-intent on a single asset, mid-diligence on a portfolio deal, in the final stretch before closing, or post-close and wondering what you actually bought, we can plug in at the right stage. The first conversation costs nothing. Everything beyond that is yours to scope. The decision belongs to you - and it is informed.
