11 Months of Weekly Aerial Construction Progress

A 11-month weekly aerial documentation engagement is one of the most useful things a project team can put on a long commercial build. The deliverable set is consistent, the data is comparable week-over-week, and the cumulative record becomes a defensible reference for any stakeholder question that comes up during the build or after substantial completion. Here is what the engagement actually looks like in practice, what it costs, and what the project team ends up with at the end.

Why a 11-Month Build Defaults to Weekly

A 11-month build is the heart of the project duration sweet spot for weekly aerial documentation. The project is long enough that the site changes meaningfully week-over-week: site prep one visit, foundation the next, structural steel the next, walls, roof, MEP, drywall, paving, closeout. A weekly cadence captures the project at every phase transition and gives the project team a continuous dated record of where the project stood at every point.

Slower cadences (bi-weekly, monthly) lose phase transitions. Faster cadences (twice weekly, daily) capture the same information twice. Weekly is the right cadence for most active commercial builds in the 6-12 month range.

The Per-Visit Deliverable Set

The strength of a long-term engagement is consistency. The per-visit deliverable set is the same every week, structured the same way, with the same file naming and the same data handoff. The project team never has to re-train on the documentation as the project moves through phases. The standard per-visit set includes:

• A complete aerial photo set from multiple angles and altitudes, dated and geo-tagged.
• Four 360-degree corner panoramas (one at each corner of the site).
• A current orthomosaic of the entire site at the time of the visit.
• A short aerial video pass for stakeholder use.
• A written narrative of what was observed at the visit, structured to drop into a weekly project update.

Add-ons like volumetric stockpile measurements and GCP-supported orthomosaics are added at defined points in the engagement rather than every week. The point is to keep the per-visit deliverable consistent so the cumulative record is clean.

The Four Corner Panoramas

The four corner panoramas are a contextual record of the site from each cardinal direction. They show the project in its surroundings: approach roads, neighboring properties, site access, laydown areas, vertical construction as it rises above grade. Over a 11-month engagement, the cumulative panorama set becomes a complete visual record of the build from every angle.

Panoramas are useful for stakeholders who want to see the site without flying to it. Owners, lenders, and remote GC team members can pull a panorama from any week and see the project as it stood at that visit. The set is also reusable for marketing, community relations, and project closeout presentations long after construction is done.

An Orthomosaic at Every Stage

An orthomosaic is a top-down, geometrically corrected aerial image of the entire site. Distances and areas in the ortho are accurate. The ortho is the right base map for measuring progress, tracking the building footprint as it grows, and supporting volumetric calculations on material stockpiles.

Producing an ortho at every visit gives the project team a dated, top-down map of the site at every point in the build. The cumulative ortho set is the right reference for any question about what the site looked like at a specific week, what the building footprint was at a specific phase, or how the parking lot subgrade progressed through the earthwork phase.

Volumetric Tracking Across the Engagement

Volumetric measurements are added at defined measurement points across the site (the building pad, the parking lot subgrade, the gas station pad, the material stockpile areas) at defined points in the engagement. The standard cadence is every 4-8 weeks during the earthwork phase, plus any point where a material quantity is needed for a progress payment or a cut-and-fill reconciliation.

The output is a per-measurement volume figure (cubic yards) and, where a density is available, a derived tonnage figure (tons). The volumetric data supports progress payments to the site work subcontractor and a final reconciliation at substantial completion. The data is documentation and planning grade, not survey grade, so it is appropriate for operational decisions, progress payments, and internal reporting.

The Subcontractor Handoff

Some long-term engagements are run direct (the GC hires the aerial documentation partner). Others are run through a subcontractor relationship: a national aerial data provider hires the on-site capture partner to run the engagement on their behalf, then processes the data downstream and delivers to their end client.

The subcontractor handoff is straightforward in practice. The data provider sets the visit cadence, the deliverable spec, and the quality bar. The on-site capture partner handles every weekly visit, every deliverable, and the secure transfer of the data back to the data provider at the end of each visit. The capture partner is the boots on the ground; the data provider is the brand-facing layer. The relationship works when both sides run the same play consistently, week after week, for the duration of the engagement.

What the Engagement Looks Like: Start vs Finish

Two 360-degree aerial panoramas from the same corner of a real 11-month weekly engagement. The first capture is from day one, when the site was still a graded pad. The second is from the final visit, when the building was complete and the parking lot was open. Click "View 360°" on either image to pan around the site.

Site Overhead: Start vs Finish

The same parcel from straight overhead. The orthomosaic at every visit is a geometrically corrected, top-down map of the entire site. Distances and areas on each image are accurate at any scale, so the ortho set is the right reference for any measurement, layout, or volumetric question over the life of the engagement.

11-Month Engagement Cost

A 11-month weekly engagement is priced on the per-visit rate, the deliverable scope, and any add-ons (orthomosaics, panoramas, volumetrics). The per-visit rate for a standard commercial site starts at $375. A 11-month weekly engagement is roughly 44 visits, putting the engagement in the $16,000-$18,000 range before add-ons.

Add-ons vary by project. A standard add-on set (ortho at every visit, four corner panoramas at every visit, volumetric measurements at defined points) is typically $200-$400 per visit, putting the total engagement in the $25,000-$35,000 range. Volume discounts apply for engagements that lock in a multi-month cadence upfront. Reach out with your project details and we will provide a project-specific quote within 48 hours.

A 11-month weekly engagement is forty-eight-plus consecutive weeks of consistent deliverables. The cumulative record becomes a defensible reference for any project question, dispute, or audit, and the data set is the right foundation for a final time-lapse compilation at substantial completion.
