Engineering and construction surveying

Engineering and construction surveying translates design information into controlled positions and measurements on site. Maplas works with the approved drawings, coordinate information, benchmarks, tolerances, construction sequence and reporting needs supplied by the project team. Services may include survey-control establishment, building or structural-grid setting out, foundation and utility setting out, road or pipeline alignment, levelling, profiles, drainage surveys, as-built measurements, construction checks and quantity or volume measurements. The scope should clearly identify who provides design approval, control coordinates, site access and the latest drawing revision. Field observations are checked against the agreed references, and discrepancies that affect the work are raised for clarification rather than silently assumed. Outputs can include set-out records, coordinates, levels, marked positions, drawings, tables, digital files or a technical summary. Availability depends on programme, location, required accuracy, site safety and the professional requirements applicable to the assignment.
