Measured Building & Topographical Surveys

Accurate existing information before design begins.

Measured building and site surveys for homeowners, designers, engineers and developers, producing clear information for planning, design, Building Regulations and construction.

Reliable base information

Good design depends on knowing what is already there

A survey should capture the information the next stage of the project actually needs — accurately, clearly and without unnecessary detail.

Williams Survey & Design provides measured surveys of existing buildings and topographical surveys of sites throughout Lancashire and the wider North West.

The required level of detail is agreed before work begins, so a small extension survey is not treated like a large development site and a simple floor-plan survey is not priced as though full elevations, sections and external levels are required.

The survey scope is tailored to the job. This helps control cost while still providing designers, engineers and contractors with a dependable base for the work that follows. A small plot with steep ground, difficult access or remote control requirements can involve more work than a physically larger but straightforward site.

Two core survey services

Building information and site information

  • Doors, windows and structural features
  • External elevations where commissioned
  • Building heights and relevant levels
  • Roof form and visible external features
  • Sections where the project requires them
  • External features relevant to proposed work
Typical outputs: PDF • DWG

Topographical & Site Surveys

Measured site information recording physical features, levels and relationships needed for design and development.

From £650
  • Visible boundaries, walls, fences and hedges
  • Ground levels, spot levels and changes in elevation
  • Existing buildings and structures
  • Roads, paths and access points
  • Trees and significant vegetation where required
  • Visible drainage features and service covers
  • Contours where appropriate to the site
  • Relationship to relevant neighbouring features
Small plots to larger sites • quoted to scope

Survey control & field capability

More than simply collecting points

A dependable topographical survey starts with a suitable control strategy. On simple sites this may be straightforward; on constrained or sloping sites, control may need to be transferred through several stations before the main survey can begin.

Williams Survey & Design uses appropriate professional survey equipment and checking procedures to establish a coherent site framework before converting the field observations into CAD.

Robotic total-station survey Used for coordinated detail, levels, reflectorless observations and difficult-to-reach features where appropriate.
Traverse & resection Control can be carried through or around a site where direct occupation of every area is not practical.
Level control Spot levels, changes in elevation, banks and other vertical relationships are tied into the agreed survey datum.
CAD processing & checks Raw field observations are reviewed, adjusted where required and presented as a clear, usable drawing rather than an unprocessed point cloud.
From site to drawing

Professional capture — usable CAD information

Site survey Professional total-station survey used to establish positions, levels and relationships across the site.
CAD processing Survey information converted into a clear drawing base for design, planning, engineering or construction use.
Survey workflow

Survey → Process → CAD → Deliver

The survey is only useful if the information captured on site is translated into a clear and dependable drawing package.

1

Define the scope

We agree what needs recording, the drawing outputs required and the level of detail appropriate to the project.

2

Capture on site

Dimensions, levels and relevant features are measured using appropriate survey equipment and cross-checks.

3

Process & draw

Field information, control and levels are checked and converted into CAD drawings using the agreed coordinate basis, datum and drawing structure.

4

Issue the survey

Final drawings are supplied in the agreed formats together with any relevant survey notes or limitations.

Typical deliverables

Information prepared for the next stage of the project

Floor Plans

Existing internal layouts, openings, wall positions and dimensions appropriate to the commissioned scope.

Elevations & Sections

Existing external elevations and sections where required for planning, design or technical coordination.

Site / Topo Plans

Site features, spot levels, contours and relevant relationships presented in a clear plan format.

PDF & DWG

Presentation-ready PDF drawings and editable CAD files where included in the agreed commission.

Important scope distinctions

What a standard measured / topo survey does not automatically include

Normally included where relevant

  • Visible and accessible physical features agreed in the survey scope
  • Dimensions, levels and positions needed for the commissioned drawings
  • Visible site boundaries and features as physically observed
  • Clear survey notes and drawing information appropriate to the project
  • Local datum / survey control appropriate to the commission unless another coordinate basis is agreed
  • Control checks and closure / consistency checks appropriate to the survey method and site

Specialist or additional work

Unless expressly commissioned, a standard measured or topographical survey does not automatically establish:

  • Legal title boundaries or ownership
  • Underground utility positions
  • Drain runs that are not visible at surface level
  • Geotechnical or ground-condition information
  • Tree species / arboricultural constraints
  • Asbestos or hazardous materials
  • National Grid / Ordnance Datum coordinates or specialist engineering control where not agreed in advance

Where National Grid / Ordnance Datum control is required, the coordinate and level basis should be agreed before survey so the appropriate control strategy can be allowed for. Where other specialist information is required, we can identify the need for suitable additional survey or professional input.

Why site complexity matters

A small development plot can still require a substantial survey

A recent North West development-site survey involved a relatively modest plot but challenging survey logistics. The usable site could not simply be occupied from one convenient station.

Control transfer: existing control had to be carried several hundred metres to establish reliable site control.
Difficult terrain: steep banks and level changes affected instrument positions, sight lines and the density of observations required.
Multiple setups: traverse and resection methods were used to maintain continuity of control around the site.
Detailed site capture: buildings, structures, access, top and toe of banks, significant vegetation, visible services and other relevant features were recorded for planning and design use.
What the client receives

Not just a collection of survey points

The value is in turning field observations into a coherent survey drawing that another professional can actually use.

  • Survey control checked before final drawing production
  • Levels reviewed in context rather than accepted blindly
  • Duplicate or misleading linework cleaned during CAD processing
  • Contours and spot levels presented at an appropriate density
  • Features labelled and layered clearly for planning, design and consultant use
  • Assumptions and limitations identified where relevant
A survey tailored to the project

Property size and site complexity matter

Survey cost and time are driven by much more than the word “measured” or “topographical”.

Building size: a small two-bedroom house and a large multi-storey property require very different amounts of site and CAD time.
Drawing scope: floor plans only are different from plans, elevations, sections and detailed external information.
Site area: a compact domestic garden is different from a large plot, estate or development site — but physical size alone does not determine the fee.
Control & access: long traverses, restricted sight lines, occupied buildings, roads, steep ground or remote control points can add significant field time before the main detail survey begins.
Feature density: levels, trees, walls, drainage covers, structures, slopes and access constraints all affect survey time.
Coordinate / datum requirements: local control, National Grid, Ordnance Datum or other project control requirements should be established before survey.
Required detail: the survey should match the accuracy and information needs of the project rather than using one fixed specification for everything.
