Heavy Civil Infrastructure: Design of
Temporary Works
With our broad experience of civil construction in a marine environment, we are well poised to offer bespoke solutions to facilitate the efficient implementation of your project.
With close collaboration between our marine, structural, and mechanical teams, we tend to each step of the project to ensure design and operational efficiency are prioritised, providing you with lean, timely, and cost-effective solutions.
Our international project track record, tactical approach to method engineering, and diverse repertoire in temporary works are the trinity that can help guarantee a successful collaboration.
Why work with TWD?
TWD is specialised in designing methods and equipment tailored to improving the efficiency and safety of construction. We review the full operation to set out the key equipment functionalities required for the best operational gains. Our structural and mechanical designs shorten cycle times, reducing operational costs at the site. To learn how we can assist you in your construction projects, download our track record now.

Jetties, Quays & Wharves
Jetties, quays, and wharves, as well as mooring/berthing dolphins, are pile-based constructions that compose near-shore marine infrastructures such as ports and harbors.
The piling process has a strong influence on the project installation timeline. With the use of smart template tools, piling operations can be streamlined to reduce installation time and double handling, and eradicate unnecessary manual operations.
TWD is experienced in dealing with cylindrical, sheet, cellular, and combi-wall piling techniques. With our innovative approach, we will supply a bespoke solution to facilitate your piling requirements. Our track record confirms a marked increase in output after tool implementation – notably Dover’s ‘Walking Piling Gate’, which saw an output increase of 50%.
Tunnels / Outfalls
For the construction of tunnels, either transportation tunnels, sewers or outfall constructions, diverse construction methodologies are applied. Marine tunnel sections can be drilled, floated out and immersed, or lifted into place.
The construction sequence, as well as the design of the required temporary works, requires in-depth understanding of working on water. TWD is an expert on the matter, and supports contractors with:
- Method engineering and development of story boards
- Barge mooring, ballasting and stability analyses
- Lifting analyses and design of tailored lifting or lowering equipment
- Third party verifications or on-site coordination
Bridges
Suspension bridges are becoming ever more popular due to their long-span capabilities, relatively low material requirement, fast fabrication time, and height. Often, segments are pre-fabricated before being lifted from pontoons and secured in place. This requires thorough lifting and stability assessments, taking operational and environmental conditions into account. With our experience, we can verify your installation procedure, and provide robust designs to ensure a safe and efficient operation. Some of our relevant services include:
- Design of piling frames/templates
- Lifting analyses and design of tailored lifting frames
- Bridge-launch equipment / launching girders
- Tailored gantry cranes
Breakwaters
A breakwater is a permanent structure, often as part of a coastal management system, which protects against waves and tides. They often take the form of caissons, either pre-fabricated and transported to site, or sometimes constructed locally. Caisson transportation and installation requires in-depth marine analyses to cope with the heavy loads. TWD can provide various solutions to ensure a successful operation:
- On/Offloading analyses and design of skidding systems
- Barge mooring, ballasting and stability analyses
- Robust seafastening solutions
- Third party verifications and on-site coordination
