Our Underground Gas Pipe Laying Services
Construction and installation of underground gas pipes: Our gas pipes are constructed with different materials ranging from PVC, HDPE to high-strength steel with anti-corrosion coating so they can last long without any damage, even during excavation and earthworks.
Regular inspections and repair of underground gas pipes: We carry out frequent gas pipe tests and inspections to ensure that the pipeline network is in safe working condition. Any leaking pipes will be repaired quickly and safely.
Replacement of underground gas pipes: We will carry out the necessary replacements of any damaged or worn-out pipes as old and corroded pipes will affect the integrity of the pipelines.
Our Underground Gas Pipe Laying Process
At Lih Ming Construction, we follow a systematic, safety-first approach to ensure that every project delivers reliable and long-lasting pipelines.
Risk Assessment & Site Checks
Every project begins with detailed risk assessments and site surveys, ensuring compliance with the Energy Market Authority (EMA), the Building and Construction Authority (BCA), and the Workplace Safety and Health (WSH) standards. This step helps us identify existing utilities, assess soil conditions, and prepare safe working methods.
Excavation & Preparation
Once approvals are in place, our team manages trenching, traffic control, and safety barricades. We plan carefully to minimise disruption to the surrounding infrastructure and ensure smooth progress on-site.
Pipeline Installation
Using durable materials such as PVC, HDPE, or steel with anti-corrosion coatings, our specialists install pipelines according to precise engineering specifications. This guarantees strength, durability, and long-term reliability.
Pressure & Leak Testing
After installation, we perform hydrostatic and air pressure testing with advanced equipment. These stringent checks confirm that the pipe materials are structurally sound and free from leaks before commissioning.
Backfilling & Site Restoration
Once testing is complete, trenches are carefully backfilled and compacted. We then restore the site to its original or often improved condition, ensuring a safe and tidy environment.

FAQs
How much does underground gas pipe laying cost in Singapore?
The cost of underground gas pipe laying depends on several factors, such as pipe size, length of the pipeline, soil conditions, and the complexity of the site. Urban areas with existing utilities may also require additional safety measures, which can affect pricing. After conducting a detailed site assessment, a transparent, itemised quotation is provded so clients clearly understand the breakdown of costs before work begins.
Which regulations must underground gas piping contractors follow in Singapore?
Gas pipe installation is highly regulated in Singapore to ensure public safety. Contractors must comply with strict requirements set by the EMA, BCA, PUB, and WSH. Choosing a contractor with the proper certifications ensures the project is completed safely and legally.
How long does it take to install underground gas pipes in Singapore?
The timeline for installation varies depending on project size and complexity. Smaller residential or commercial projects may take only a few days to complete, while large-scale industrial pipelines or city infrastructure projects can span several weeks. Factors such as weather conditions, soil type, and the presence of existing underground utilities also influence the duration of the project.
What safety checks are required before laying underground gas pipes?
Before pipe laying begins, we carry out rigorous risk assessments, utility mapping, and trial holes to avoid damage to existing services. All works are conducted under approved permit-to-work systems. During and after installation, pressure and leak testing are carried out with calibrated equipment to verify pipeline integrity. These checks are essential to meet authority requirements and ensure public safety.
What materials are used for underground gas pipelines in Singapore?
Gas pipelines are typically constructed from PVC, HDPE, or high-strength steel, depending on the pressure requirements and soil conditions. For steel pipelines, protective coatings and corrosion control methods (such as cathodic protection) are applied to extend the service life. These materials are chosen for their strength, durability, and ability to withstand Singapore’s demanding underground conditions.
Do underground gas pipes in Singapore need regular inspection and maintenance?
Yes. Even with durable materials, underground pipelines require routine inspections to detect leaks, monitor pressure, and check corrosion protection systems. Regular maintenance helps extend the lifespan of pipelines, reduces the risk of failures, and ensures compliance with safety regulations. Preventive maintenance also avoids costly emergency repairs in the future.
How do I choose a certified underground gas pipe laying contractor in Singapore?
When selecting a contractor, it is important to check for official licences and certifications from EMA, BCA, and PUB. A strong track record, proven safety record, and experience in handling similar projects are equally important. Asking for past project references and confirming adherence to compliance standards will help ensure you engage a reliable partner.
