Process

How a site mandate unfolds

The same path on every project: you know who shows up, when, and what you receive.

  1. Your drawings come in

    Construction drawings, schedule and build sequence: we confirm mobilization and the technical director assigned to your site.

  2. Data preparation

    Our calculators prepare the layout coordinates and the working drawings used in the field.

  3. Layout and control

    The technician sets the markers, checks alignments and elevations, and adapts visits to your progress.

  4. As-built records

    Progress surveys and as-builts are delivered at the agreed milestones, in your software formats.

Your questions

Construction surveying: straight answers

Can you mobilize a crew quickly on an active site?

Yes. Our construction mandates are billed at an hourly rate, with a master agreement available for recurring clients, allowing us to respond quickly as the site progresses. Tell us your deadline in the request.

How do we receive the layout data?

Layout coordinates are delivered in DWG or LandXML for your robotic total station, and a technical director follows your job site from layout through to the as-built.

Do you bill a fixed fee or an hourly rate?

Construction surveying is generally billed hourly, since duration depends on actual site progress. You receive a weekly summary of hours, with no surprise at invoicing.

Do you produce as-built surveys?

Yes, at each key milestone or at the end of the mandate, as agreed, to document how the completed work compares with the plans.
