Bridges & Overpasses
Dunbar Construction Ltd. has extensive experience in the construction of bridges and overpasses that support safe and reliable transportation infrastructure. These structures require precise engineering, specialized equipment, and skilled crews to ensure long-term durability and structural integrity. Our team works closely with project engineers and contractors to deliver bridge structures that meet strict safety standards while supporting the transportation networks that communities rely on.

Bridge Rehabilitation
Over time, bridge structures can experience wear from weather, traffic loads, and aging materials. Dunbar Construction provides bridge rehabilitation services designed to restore and strengthen existing structures while extending their lifespan. This work may include structural repairs, concrete restoration, and reinforcement to ensure bridges continue to operate safely and efficiently for years to come.

Temporary Structures
Temporary structures are often required to support construction activities while permanent infrastructure is being built or repaired. Dunbar Construction installs and manages temporary structural systems that maintain safety and stability throughout a project. These structures allow work to proceed efficiently while minimizing disruption to surrounding infrastructure and project operations.

Pile Driving
Pile driving is a critical foundation method used to support large infrastructure projects such as bridges, retaining walls, and other structural systems. By driving steel, concrete, or timber piles deep into the ground, strong and stable foundations can be created even in challenging soil conditions. Dunbar Construction uses specialized equipment and experienced operators to ensure piles are installed accurately and securely to support long-lasting structural performance.

Retaining Wall Structures
Retaining walls are built to hold back soil and stabilize slopes in areas where elevation changes occur. These structures are essential for protecting roadways, bridges, and development sites from erosion and ground movement. Dunbar Construction designs and builds durable retaining wall systems that provide long-term support and structural stability for infrastructure and land development projects.

Cast-in-Place Concrete / Concrete Formwork
Cast-in-place concrete construction allows structural elements to be formed and poured directly on site, creating strong and highly durable components for infrastructure projects. Dunbar Construction specializes in concrete formwork and structural concrete installations that require precision and careful planning. This method is commonly used for bridge components, foundations, retaining structures, and other critical infrastructure elements.

Earthworks & Grading
Earthworks and grading are essential steps in preparing construction sites for infrastructure development. These services involve moving and shaping large volumes of soil to create stable foundations and proper drainage conditions. Dunbar Construction performs large-scale earthworks using modern equipment and experienced crews to ensure sites are properly prepared for safe and efficient construction.

Land Development
Land development involves preparing raw land for future infrastructure and construction projects. Dunbar Construction provides site preparation services that support roads, utilities, and structural foundations required for development projects. Our team works to ensure that sites are properly graded, stabilized, and ready for the next stages of construction. (Image is an AI example.)
Concrete Shot Blasting
Concrete shot blasting is a specialized surface preparation process used to clean and texture concrete surfaces. This method removes contaminants, coatings, and surface imperfections while creating a textured finish that improves bonding for coatings, repairs, and overlays. Dunbar Construction uses shot blasting to prepare concrete surfaces for restoration, maintenance, and long-term durability.
