Pre and Post Construction Survey Services and Precon Survey in Singapore
Pre and Post Construction Survey and Precon Survey
In Singapore’s fast-paced construction environment, protecting property and ensuring accurate documentation are not just best practices—they’re requirements. Whether you’re planning a high-rise, infrastructure development, or a residential build, documenting the site’s condition before and after work begins is essential. That’s why Exergy Technologies offers comprehensive Pre and Post Construction Survey and Precon Survey services to clients across the island.
Our dual-phase survey solutions help developers, engineers, contractors, and property owners reduce disputes, meet regulatory requirements, and establish baseline conditions of surrounding properties before and after construction activities.
Why You Need a Pre and Post Construction Survey
A Pre and Post Construction Survey serves as an official record of a site and its surrounding features—such as roads, sidewalks, drainage, and adjacent structures—before construction begins and after it concludes. This documentation protects all stakeholders in the event of claims, complaints, or damage disputes.
In a dense urban environment like Singapore, construction work can easily impact neighboring properties. Vibrations from excavation, pile driving, or demolition work may cause cracks in nearby buildings or roads. With a professional Pre and Post Construction Survey, you’ll have high-quality photographic and written evidence of the site’s original condition, helping to avoid costly liability.
What is a Precon Survey?
A Precon Survey (short for Pre-Construction Survey) focuses solely on the initial phase of a construction project. It documents the current condition of surrounding structures and infrastructure before any work begins. It’s the first half of the full Pre and Post Construction Survey and is particularly valuable for safeguarding your interests when starting major projects.
Our Precon Survey includes:
-
High-resolution video and photo documentation
-
Observations of visible cracks, tilts, and surface wear
-
Detailed reports on roads, curbs, retaining walls, and utilities
-
Geotagged and time-stamped data for legal validity
Clients typically use a Precon Survey as part of risk management and insurance protocols. It also promotes transparency with nearby property owners and complies with local authority guidelines.
Detailed Pre and Post Construction Survey for Legal and Regulatory Protection
At Exergy Technologies, our team delivers meticulous Pre and Post Construction Survey services to provide developers and contractors with peace of mind. These surveys are essential for:
-
Public infrastructure projects like MRT developments, tunnels, or utility lines
-
Private residential or commercial developments next to shared buildings
-
Industrial sites with heavy excavation or piling work
-
Demolition or reconstruction activities in high-density neighborhoods
Each Pre and Post Construction Survey is conducted with advanced tools such as drones, 3D laser scanners, and robotic total stations. This ensures the data we capture is reliable, repeatable, and defensible in court or insurance claims.
We also handle the Precon Survey independently for clients who need documentation before construction starts but may not require post-construction data unless damage is suspected or reported.
What’s Included in Our Survey Packages?
Both Pre and Post Construction Survey and Precon Survey packages include:
-
Site walkthroughs by licensed surveyors
-
High-resolution imagery with GPS metadata
-
Written condition reports of physical assets
-
Optional vibration monitoring equipment
-
Signed acknowledgments by stakeholders or neighbors (if required)
Post-construction surveys revisit the same areas for comparison. Any new damage or deviations are identified and documented with side-by-side comparisons to the pre-construction data.

Frequently Asked Questions
What is the difference between a Precon Survey and a Pre and Post Construction Survey?
A Precon Survey refers specifically to a pre-construction survey conducted before any construction activity begins. It documents the condition of existing structures, roads, drainage systems, and surrounding infrastructure. The purpose is to create a visual and written record that can be referred to in case of future claims or disputes. On the other hand, a Pre and Post Construction Survey includes two phases: one before and one after the construction process. The pre-construction phase is essentially the same as the Precon Survey, but the post-construction phase documents the condition of the same structures after construction is completed. This allows for a direct comparison to assess whether any damage occurred during the project. In short: Precon Survey = Before construction only Pre and Post Construction Survey = Before and after construction At Exergy Technologies, we offer both options. Some clients choose only a Precon Survey for basic risk management, while others opt for the full Pre and Post Construction Survey to maintain complete transparency and avoid liability.
Who needs a Precon Survey or Pre and Post Construction Survey in Singapore?
Both a Precon Survey and a Pre and Post Construction Survey are highly recommended for anyone involved in a construction project that may impact nearby properties or infrastructure. This includes: Developers starting new residential or commercial buildings Contractors performing excavation or piling near adjacent buildings Government agencies responsible for infrastructure upgrades Demolition contractors working in urban areas Engineers and consultants preparing construction risk assessments In Singapore, where developments often take place in high-density zones, the risk of affecting neighboring structures is significant. A Precon Survey provides documentation that helps avoid blame if existing cracks or defects are later attributed to your project. Meanwhile, a Pre and Post Construction Survey gives you a full record, ensuring complete protection and compliance. Many of our clients at Exergy Technologies also use these surveys to fulfill requirements set by BCA, HDB, or insurance providers.
What does a typical Pre and Post Construction Survey include?
A complete Pre and Post Construction Survey includes several critical elements designed to capture and compare site conditions accurately. At Exergy Technologies, our standard package includes: Initial Precon Survey: Our team visits the site before construction begins to document all surrounding structures using high-resolution photography, video, and detailed notes. Site Condition Report: A written report outlines the conditions of nearby buildings, roads, sidewalks, retaining walls, and utilities. Any visible cracks, stains, or deformations are noted. Post-Construction Visit: Once the project is completed, we revisit the same locations to observe and record any changes or new damage. Comparison Analysis: We create a side-by-side comparison to determine whether the construction activity caused any structural impact. Optional services may include drone mapping, vibration monitoring, and stakeholder sign-offs. Whether you opt for a basic Precon Survey or the more comprehensive Pre and Post Construction Survey, you’ll receive clear, time-stamped evidence to support your construction process from start to finish.
