Key takeaways
- The Problem: Developers and owners running several projects at once inherit a different reporting habit from every contractor, so investors, lenders and the board are shown evidence that cannot be compared or checked.
- The Solution: One owner-defined evidence standard, captured by drone surveys, fixed cameras and 360° walkthroughs on a set cycle at every site, held in one record that every contractor works to.
- The ROI: 60% fewer site visit hours, investor and lender updates built from the same verified record, and contractors held to one standard instead of their own.
The Challenge: Every Contractor Brings Their Own Record
A developer with several live projects rarely has one main contractor. Each site has its own builder and its own idea of a progress report: one sends a spreadsheet, another a folder of phone photos, a third a slide pack that only shows the good news.
For the owner, this is a governance problem before it is a reporting problem:
- Investors and lenders get claims, not evidence. Quarterly updates are assembled from whatever each contractor chose to send, and nobody outside the project team can check them.
- Contractors set the standard. When the owner has not defined what evidence is required, each contractor decides how much to show, and how often.
- Disagreements have no shared reference. When a progress payment claim, a handover or a variation is questioned, both sides argue from their own photos.
- Programme managers travel to confirm. The only way to trust a report is to visit the site, which does not scale across a portfolio.
The YelloSKYE Approach: The Owner Sets the Standard
YelloSKYE helps the owner define one evidence standard and apply it to every site, whoever the contractor is. Construct IQ captures each project the same way, using the same sensors on the same cycle, and our certified pilots or your on-site teams carry out the capture.
- Drone surveys: Measurable orthomosaics at ±2–3 cm accuracy, with earthwork and stockpile volumes measured within 1–3%. Drone flights follow the rules of the national aviation authority where the site sits (for example the FAA in the US, the CAA in the UK or the GCAA in the UAE).
- Fixed cameras: A continuous, timestamped record of site activity from stable positions, so milestones are captured whether or not anyone is on site.
- 360° walkthroughs: Floor-by-floor records of interior work, MEP and finishes before they are covered.
- Laser scanning where needed: Scan-to-BIM at ±5 mm for elements where design compliance has to be proved.
Processed outputs are delivered within 48–72 hours of capture, so the record stays current enough to act on.
How One Standard Changes Owner Governance
| Governance task | Without a standard | With one owner-defined record |
|---|---|---|
| Investor and lender updates | Built from contractor reports | Built from the same captures every quarter |
| Contractor accountability | Each contractor reports their own way | Every contractor is measured against one record |
| Progress payment claims | Argued from competing photos | Checked against dated captures |
| Board review | Different formats per site | Like-for-like comparison across projects |
| Handover | Records gathered at the end | Records built up through the build |
Writing the Standard into Contracts
The standard works best when it is set before work starts. Owners can write it into contractor appointments so that every builder knows from day one:
- What will be captured, how often and with which sensors.
- That the owner's capture record is the reference for progress, quality checks and handover.
- That progress payment claims will be reviewed against the latest dated capture.

Reporting to Investors and Lenders
Investors and lenders want to know whether money is being spent on the work claimed, whether the programme is holding and whether risks are raised early. A single capture record answers all three with evidence they can check themselves.
Because every site is captured the same way, the programme manager can put projects side by side in the DEX platform and report on the whole portfolio from one source. For more on comparing sites in one dashboard, see portfolio monitoring with DEX.
The Impact
The owner, not the contractor, decides what good evidence looks like. Site visits are kept for issues the data flags, which is where the reduction in site visit hours comes from, and every contractor is held to the same bar.
Who This Is For
- Residential developers running several towers or phases at once.
- Commercial and mixed-use developers with multiple contractors on one masterplan.
- Programme managers and owner's representatives reporting to boards, investors or lenders.
