An As-Built Survey is a land surveying service that documents the exact dimensions and locations of a property or structure after construction has been completed. Unlike design or layout surveys, which focus on planned structures, an as-built survey shows the real-world conditions of a project. It captures the final position of buildings, utilities, roads, drainage systems, and other features, providing a reliable record of what was actually built on the ground.
At MLL III Land Surveying and Mapping Services, we provide accurate, legally compliant, and certified as-built surveys for property owners, contractors, developers, and government agencies. Our as-built plans ensure that projects comply with approved designs, construction permits, and regulatory requirements in the Philippines.
Services
As-built surveys are critical for various reasons:
Compliance with Permits and Approvals: Many LGUs and government agencies require as-built surveys to confirm that construction followed approved plans.
Occupancy Permits: Property owners must submit as-built surveys to obtain an occupancy permit for completed buildings.
Land Titling and Financing: Banks, real estate buyers, and titling offices require as-built plans to confirm the accuracy of property documents.
Construction Validation: Contractors and developers need as-built data to verify that structures were built as designed and within property boundaries.
Utility Mapping: As-built surveys document the exact locations of underground or above-ground utilities for future maintenance and expansion.
Without an as-built survey, property owners risk delays in securing occupancy permits, difficulties in land titling, or disputes over non-compliance with building codes.
Services
At MLL III, we follow a detailed process to ensure that as-built surveys are accurate and legally compliant:
Client Consultation – We confirm project requirements and identify which features must be documented.
Review of Design Plans – Our team reviews original design drawings and permits to understand expected construction outcomes.
Field Data Collection – Using GNSS, total stations, and drones (UAVs), we measure the actual position and dimensions of completed structures.
Comparison with Plans – Measured data is compared against approved design drawings to identify deviations.
Data Processing and Mapping – Using AutoCAD Civil 3D and GIS platforms, we prepare detailed as-built drawings and technical descriptions.
Validation and Certification – Results are reviewed for accuracy, and all outputs are certified by a licensed geodetic engineer.
Final Deliverables – Clients receive sealed plans, digital files (DWG/PDF), and certified documents ready for submission to government agencies or financial institutions.
Services
For Property Owners: Provides proof of compliance with approved construction and facilitates occupancy permits.
For Developers: Ensures projects meet regulatory requirements and prevents disputes with clients or contractors.
For Contractors: Helps verify that structures were built to design specifications and assists with project turnover.
For Banks and Buyers: Serves as reliable documentation for financing, titling, and property valuation.
For Government Agencies: Confirms compliance with zoning, building codes, and environmental regulations.
Our as-built surveys comply with the Geodetic Engineering Act of 1998 (RA 8560) and the requirements of LGUs, DENR, HLURB, DHSUD, and LRA. Every survey is supervised and certified by a PRC-licensed geodetic engineer, ensuring that results are legally valid and admissible for permits, titling, and regulatory approval.
At MLL III, we use modern surveying technology to produce accurate and efficient as-built surveys:
GNSS positioning systems for geodetic accuracy
Total Stations for precise measurement of structures and features
UAVs/Drones for aerial documentation and mapping of large sites
Civil 3D, AutoCAD, and GIS software for detailed plan preparation
These tools allow us to deliver certified as-built plans faster while maintaining the highest level of accuracy.
Residential Projects: Homeowners submit as-built surveys to obtain occupancy permits and secure property loans.
Commercial Developments: Malls, office buildings, and factories require as-built documentation for permits and legal compliance.
Infrastructure Projects: Roads, bridges, and drainage systems must be documented for government acceptance and turnover.
Subdivision Developments: As-built surveys confirm that roads, utilities, and house lots match approved subdivision plans.
Utility Mapping: Utility companies rely on as-built surveys to maintain accurate records of water lines, electrical cables, and sewer systems.
