Survey Support for Construction and Infrastructure
Setting-out, levels, alignments, control and verification survey support for construction works.
01Overview
Engineering surveying provides positional, dimensional and elevation information required during the planning, setting-out, construction and verification of engineering works.
On a construction site, small positional errors can multiply into expensive rework. DASFADS supports contractors, consultants and project owners with survey control, setting-out and checking that keeps works aligned with the design. We coordinate closely with the design and site teams so that survey information arrives when it is needed and in the form it is needed.

Deliverables are defined by the assignment and aligned with your project's reporting requirements.
05What to provide
Sharing this information with your request helps us scope the work accurately and respond faster.
- Project location and construction stage
- Design drawings and reference coordinates
- Required accuracy or tolerances, where specified
- Site access, induction and safety requirements
- Construction schedule and key milestones
Our approach
We coordinate with the client or design team to understand reference coordinates, design information, tolerances, access requirements and construction schedules before mobilising to site.
06Scope considerations
Before you commission this service
Survey support is delivered against the design information, reference control and tolerances supplied or agreed. Responsibility for design, structural adequacy and construction quality remains with the relevant design and construction professionals.
07Common questions
Can you work to our project's specified tolerances?
Yes. Tolerances are agreed at the outset, and methods and equipment are selected to suit them. Where a tolerance is not specified, we will discuss what is appropriate for the work.
Do you provide ongoing support through construction?
Survey support can be scheduled across construction stages, from initial control and setting-out through to verification and as-built records, according to the agreed scope.
