Measured Building and Topographical Survey Package: One Site Visit, Better Design Inputs
A measured building and topographical survey package combines existing building data and site context into a single commission. One site visit covers both deliverables. icelabz delivers combined survey packages across London.
Why Combine Measured Building and Topographical Surveys?
One Site Visit, Two Deliverables
Commissioning building and topographical surveys separately means two site visits, two invoices, and two sets of data to coordinate. A combined package delivers both from one site visit.
Single deployment — One surveyor covers both building and site.
Coordinated data — All data in the same coordinate system.
Lower cost — Combined packages cost less than two separate commissions.
Faster delivery — Both deliverables arrive together.
Better Design Data
When building and site data come from the same survey, they are fully coordinated. Levels relate directly to the site model. Building dimensions sit correctly in the site context. No inconsistencies between separate survey datasets.
Accurate setting out — Building position verified against site levels.
Design coordination — Building design relates correctly to site topography.
Planning submissions — All drawings relate consistently to the site.
What a Combined Package Includes
Measured Building Survey
Floor plans, elevations, and sections of the existing building at agreed drawing scales.
Floor plans — Every floor level drawn at 1:50 or 1:100.
Elevations — All external faces of the building.
Sections — Cross-sections through the building.
Point cloud — Optional point cloud for complex buildings.
Topographical Survey
Site plan showing levels, boundaries, and features at agreed accuracy.
Level data — Spot heights and contours across the site.
Boundaries — Accurate site boundary from Land Registry data and physical features.
Features — Trees, structures, roads, and other site features.
Services — Visible services (manholes, lampposts, overhead lines).
Combined Data
All survey data delivered in a unified coordinate system.
OS Grid Reference — All data referenced to Ordnance Survey National Grid.
Datum — Consistent level datum across building and site data.
CAD files — DWG files for design software.
PDF drawings — Print-ready drawings for planning and client presentations.
Who Needs a Combined Survey Package?
Architects
A combined package gives architects everything needed for design work: existing building dimensions and site context in one coordinated package.
Developers
Development appraisal requires building dimensions and site context. A combined package delivers both in a format ready for use.
Planning Consultants
Planning applications need consistent existing data: building drawings and site plan in the same coordinate system.
Combined Survey vs Separate Surveys
| Factor | Combined Package | Separate Surveys | |---|---|---| | Site visits | One | Two | | Cost | Lower | Higher | | Data consistency | 100% consistent | May have inconsistencies | | Turnaround | Faster | Slower | | Coordination | Single point of contact | Multiple suppliers |
