Our Projects
Bridge Construction
KWH Constructors has the experience to erect the most complex of bridge structures. Whether it's railway or road, steel box, girder or truss, cantilevered, suspension or cable-stayed, conventional or launch method, our team has the bridge erection knowledge and experience. KWH expertise covers:
- Erection by use of cableway, specialized gantries, heavy lift cranes and waterborne cranes
- Erection over rough, inaccessible or environmentally sensitive terrain
- Erection of pre-cast segmental and pre-stressed girder concrete bridges
- Pedestrian bridges
- Heavy jacking of bridges
- Pipeline bridges
Bridge Seismic Retrofits
Recent developments in seismic standards and increased importance of some structures to survive more severe earthquakes have led to the process of seismic retrofitting. Older bridges and structures are usually designed to acceptable codes and standards of their times, without provision for extra strengthening. In many cases, seismic retrofitting can be very complex and inconvenient. KWH works closely with clients to ensure that retrofitting procedures and work are carried out with high safety standards while properly balancing impact to existing usage and cost savings.
Structural Steel Construction
KWH Constructors also erects and installs other structures besides bridges. Complicated and unique installations can all be accomplished by our highly experienced field crews with the technical backing of our construction engineers.
Structural steel retrofitting for offices/restaurants often requires steel framing re-configuration. KWH has provided many commercial facilities with our supply and install services.
Our engineering department provide designs for safe temporary lifting methods and will work with the engineer-of-record to develop effective constructible alternates and time saving sequence.
Heritage Façade Shoring
KWH Constructors offer very specialized design/build façade shoring to support exterior walls of heritage structures that need to remain in place during the construction of new developments behind them.
Bulk Materials Handling & Maintenance
New Construction
As in structural steel buildings and bridges, KWH has experience upgrading or erecting new steel structures.
Maintenance
KWH Constructors provide repair, refurbishment and shutdown work for port and material handling facilities.
Emergency Repair Services
KWH provides emergency repairs, support and salvage for many unfortunate accidents that can occur at industrial terminals.
Mass Timber
Mass Timber has now become a mainstream construction material in North America. KWH Constructors recognised the growing popularity early on during the Mass Timber transformation. Our engineering office provides stability calculations and means and methods for temporary support and safe lifting throughout the project.
The nature of the work for mass timber (weight calculations, rigging requirements, critical lift plans, strategic placement in coordination with steel erection, bracing, plumbing, surveying, etc.) is all within the scope and professional practice of KWH's team of ironworkers.
