Design & Construction

Existing-condition documentation for design, coordination, and construction.

Design and construction teams need existing building information suited to the work they are planning. Datum Point Advisory provides reality capture and existing conditions modeling for design, coordination, and construction.

Coverage, measurement accuracy, and model content are defined around the intended use. For active projects, field access and capture timing are coordinated with the project team, including work scheduled to be enclosed.

Reality Capture

Terrestrial scanning and mobile mapping document accessible building conditions, with capture planned around required coverage, site access, and the project schedule.

Source data is registered to an agreed coordinate basis. Where successive capture is required, coverage and the reference basis are agreed in advance so records from different project stages can be compared.

Depending on the scope, deliverables may include:

  • Registered point clouds in E57, RCP, or LAS formats.
  • Measured plans, sections, and elevations.
  • Orthographic imagery and visual records.
  • Capture of exposed conditions before enclosure.

Capture dates, coverage, access restrictions, and known gaps are documented with the delivery.

Existing Conditions Modeling

Models are developed from captured conditions, with elements and disciplines identified in the scope. Measurement accuracy and level of development are specified separately.

The agreed model scope identifies the geometry, detail, and information required for design or coordination. Assumptions and conditions that cannot be established from the captured data are recorded.

Deliverables may include Revit models, IFC exports, DWG drawings, and coordination models. Project coordinates, file versions, and exchange requirements are agreed before production.

Scope and quality control

Each engagement defines the areas to be documented, intended uses, measurement tolerances, model requirements, deliverable formats, and acceptance criteria.

QA/QC addresses registration, coverage, and the relationship between captured data and derived drawings or models. The agreed scope defines which checks are performed and how the results are reported.

The handoff identifies the source files, derived deliverables, supporting documentation, and known limitations. Native files and open exchange formats are specified to support the receiving team’s workflow and any owner turnover requirements.

Aerial Documentation

Aerial imagery can supplement ground-based capture for exterior building conditions, site documentation, and construction progress where appropriate to the assignment.

Aerial documentation does not replace licensed surveying. Where survey control is required, work relies on appropriate furnished control and/or a licensed surveyor.

Working with Datum Point Advisory

Delivery is principal-led, with a single point of contact for scope, field coordination, and handoff.

Assignments may cover a defined area, a project phase, or successive stages of work.

The proposal establishes the scope, deliverables, responsibilities, and schedule.
