As-built Surveys

GeoWorks Arabia as built surveys verify that what was built on site matches what was designed.
We produce as built drawings, CAD files, record surveys and BIM-ready as built models that integrate directly into design and construction workflows.

What is an As Built Survey?

An as-built survey provides very detailed, precise documentation of the positioning and levelling tolerances of different elements in a construction project when it is in process or completed. In general, it is data collection of final dimensions, levels, locations and configurations of elements such as buildings, drainage, concrete slabs, steel frames, concrete frames, roads, walls, floors, utilities etc. as-built survey serve as a reference point for comparing the actual implemented construction to the original design. GeoWorks Arabia provide a wide range of comprehensive as-built surveys regularly using the latest in technology and deliverables.

Why do we require an As Built Survey?

An As-Built Survey is more than just a final check; it is a risk-management technique that highlights the gap between design and physical reality. Because we identify problems while they occur, we can resolve them while our crew and equipment are at the property. As-Built Survey provide accurate data, then no need to manually measure when doing maintenance, renovations, or expansions. Accurate survey data creates a reliable source to resolve disputes and confirm work meets the required tolerances.

If you are waiting until the end of a project is often too late. We recommend visits on a regular basis (weekly/monthly) and monitoring key elements as they are built. ensure positional and level accuracy from day one.

Who uses an As Built Survey?

Many people use as-built surveys in the construction industry. Architects and Engineers use them to verify that the construction is correct and assist with design decisions. Main Contractors and Sub Contractors use as-built surveys to verify that the construction complies with project specifications. Facilities managers maintain records of maintenance and operations. Real Estate developers and property owners use as-built surveys to assist with leasing, selling, or renovating properties. Encompass Geospatial often services Architects, Structural Engineers, Main Contractors, and Sub Contractors to supply as-built survey services for many different types of projects.

What are the limitations of an As Built Survey?

As-built surveys are very useful, As-built surveys are very helpful, but there are some limitations to them too. It can be difficult to get the data because of poor ground, hard-to-access areas, or obstructed views. Also, how good the surveyors are affects the accuracy of these surveys. Human error or equipment limitations can lead to slight deviations in actual measurements. Our team of highly competent and multi-skilled surveyors follows the best practices for each survey. we provide a variety of services and employ the latest technology in each field to give you the best result.

How can As Built Surveys be delivered?

As built surveys can be delivered in various formats depending on the specific needs and preferences of the stakeholders involved. Traditional 2D drawings present the surveyed information in a clear and easily understandable format, with any issues highlighted / dimensioned if out of a determined tolerance, actual build are compared to the design information and reported clearly as AutoCAD drawings. However, with the advent of advanced technology, Point Cloud & 3D Revit models are becoming increasingly popular. These provide a more realistic representation of the site and enable stakeholders to visualize the project accurately. Additionally, as-built survey data can be integrated with Building Information Modelling (BIM) systems, allowing for more efficient management and integration with other project data. Encompass Geospatial has a highly skilled team of topographical, engineering, measured building surveyors and our own in house Revit team to provide you with a wide array of deliverable options.

What we deliver

Installed works verification vs design
Dimensional checks and tolerance reports
CAD as-built drawings

In conclusion, as built surveys play a vital role in the construction industry, ensuring accuracy, documentation, and smooth project progression. They provide valuable insights for stakeholders, minimize errors and disputes, and facilitate future maintenance and renovations. While there are limitations, advancements in surveying technology offer various delivery options to cater to different needs. By incorporating as built surveys into construction processes, professionals can optimize projects and ensure a successful outcome.

Through a combination of laser scanning and point cloud data analysis, accuracy Total Station surveys, aerial surveys via drones, utility surveys, engineering surveys, topographic surveys, hydrographic surveys, road and highway surveys, we will match your project to the right method and technology.

GeoWorks Arabia would be happy to assist in any As-Built survey’s your project or team would require, please get in touch on the below for any requirements :

What equipment do you use for as-built capture?

total station, GNSS/GPS and digital levels with robust control.

Can you undertake staged as-builts during construction?

Yes — we can verify critical hold points and produce progressive records.

How quickly can you provide as-builts?

Depending on the specific requirements of the project, you can generally expect a delivery within 2–7 days.

Will you highlight deviations against design?

We can annotate variances and provide schedules showing differences vs tolerances.

What information is needed to start?

Approved drawings/models, coordinate system, benchmarks, tolerance requirements and access plan.

Can you integrate as-builts into BIM?

Yes — we provide DWGs and references that can be consumed by common BIM tools.
