Specifications for Land, Buildings and Utilities

In today’s fast-paced world, technology continues to shape various industries, and surveying is no exception. We produce Specifications for Land, Buildings and Utilities Traditional methods of land and building surveys have often been time-consuming and costly, requiring extensive manpower and resources. However, with the advent of aerial drone surveys, we are revolutionising the way we approach measurements and assessments 

The two main specifications we follow are: RICS Land Standards – Measured Surveys of Land, Buildings and Utilities and Environment Agency – National Standard Technical Specifications for Surveying Services.


Measured Surveys of Land, Buildings and Utilities

A well-defined measured survey specification is crucial for land, engineering, and measured building surveyors, as well as knowledgeable clients who are involved in specifying their own surveys. This document serves as a communication tool, enabling clients to effectively express their requirements and expectations regarding survey detail, accuracy, grid, survey types, formats, and final deliverables. By providing clarity on project information, contacts, timescales, data management systems, site access, omissions, and the supply of existing information, this specification ensures that all parties involved have a shared understanding of the goals and expectations of the survey.

Recognising the critical importance of the client and surveyor’s initial meeting(s) or discussions, it is recommended that any uncertainties or issues on either side are highlighted and resolved before finalising the specification. This ensures the success of the survey project and sets the stage for clear communication and collaboration throughout the process. 


What is the purpose of this survey?

Contained within this guidance note is a complete measured survey project specification. Paying particular attention to the survey detail accuracy band table, the client has the flexibility to choose which features to include in the proposed survey in the relevant section. Both clients and surveyors should also consider the notes and recommended good practices highlighted in boxes throughout the specification, unless mutually agreed otherwise.


Flexibility in Specification Length

While not all measured surveys require a full specification, in some cases they may do, for example, where the client-surveyor relationship is well-established, and expectations are clear. However, it is essential that all parties involved possess sufficient competence in the land survey (geomatics) field when specifying surveys.

A measured survey specification serves as a valuable tool for ensuring effective communication, setting clear goals, and managing expectations between clients and surveyors. By using this specification, both parties can establish a shared understanding of survey requirements, accuracy, deliverables, and other critical project details. The specification should be seen as a collaborative document, with initial discussions playing a crucial role in resolving any uncertainties or issues. With a well-defined specification in place, clients can confidently communicate their needs, and surveyors can deliver accurate and comprehensive survey results that meet and exceed expectations.


National Standard Technical Specifications for Surveying Services


Site Access and Flexibility

Aerial drone surveys provide unparalleled access to even the most challenging terrains or restricted areas. With no specific limitations on site access, we efficiently conduct surveys without requiring special arrangements, ultimately saving time and resources for our clients.


High-Resolution Photography

Utilising state-of-the-art drone technology, we capture high-resolution aerial photographs with impressive detail. The standard resolution of approximately 9504 x 6336 = 61 megapixels ensures the clarity and precision required for comprehensive analysis and documentation.


Detailed Survey Reports

To provide valuable insights and assist clients in validating surveys, we prepare detailed survey reports for all projects. These reports include essential metadata and information necessary for future reference or use in subsequent projects, ensuring a seamless continuation of survey data.


Calibration and Verification

At Angell Surveys we prioritise accuracy and follow established guidelines for the calibration and verification of surveying instruments. By adhering to RICS guidelines or accepted industry practices, the company ensures the reliability and consistency of their equipment, further enhancing the accuracy of the collected data.


Accuracy and Completeness – Specifications for Land, Buildings and Utilities

When it comes to surveying, accuracy and completeness of data are paramount. Clients rely on precise measurements to make informed decisions and undertake effective planning and design processes. This measure takes into account the error present in observed data, including residual systematic errors that remain even after measurement and removal. It is crucial to minimise these residual systematic errors to ensure the highest level of accuracy in the survey results. 

Whilst it is impossible to completely eliminate all errors, our goal is to minimise residual systematic errors as much as possible. By identifying and removing systematic errors through rigorous calibration and verification processes, surveyors can enhance the overall accuracy of the collected data. 


At Angell Surveys we embrace the cutting-edge technology of aerial drone surveys, and aim to propel the field of land, building, and utility assessments to new heights. By combining efficiency, precision, and comprehensive data collection, we continue to provide clients with top-quality surveying services. With a commitment to specifications for Land, Buildings and Utilities and National Standard Technical Specifications for Surveying Services, we are transforming the industry.
