Safety in construction is not a stand-alone procedure, it is incorporated throughout each phase of construction. Since the first stage of site preparation, to the last stage of structural completion, a safe working environment is critical to the project success and the wellbeing of the workforce.

Building sites, especially those which involve excavation and structures, are risky. The control of these risks can be achieved through proper planning, effective procedures and having a team that is aware of the need to work safely at all times.

Risk Management of Groundworks Services.

Groundworks have been the starting point of any construction project and are associated with some of the greatest risks. Special attention should be paid to excavations, alterations of soil conditions, underground utilities, and constraints of access.

Risk management should be initiated by site assessment, which is followed by a safe method of excavation, access arrangements and proper planning of the sequencing of works. Groundworks when well managed will provide the model of safety throughout the project.

Below Ground Construction and Basement Problems.

Construction of the basement causes some new complications, especially when these are carried out below the ground or when they are in the presence of other existing structures. The structural stability, water entry, and working conditions should be tightly managed.

The safe delivery is based on the combination of engineering design, systematic excavation, and constant monitoring. All phases should be synchronized to make sure that the building and the human resources are safeguarded during construction.

Temporary Structural Support and Works.

Temporaries play an important role in ensuring that it is stable when constructing. Excavation and underpinning support systems and structural propping are employed to maintain the safety of partially complete components.

These systems have to be designed, installed and checked. An effective temporary works plan will greatly minimize the chances of collapsing, moving, or collapsing without prior warning.

The relevance of a talented Workforce.

Qualified staff is core to high safety standards. The experienced operatives know about the working conditions on the site, adhere to safe working practices and react efficiently to the appearing challenges.

Training, supervision and effective communication will ensure that all team members play their role to ensure they provide a safe and productive working environment. Expert teams not only minimize risk but also enhance the overall project delivery.

Waterproofing and Long-term Protection.

Safety is not only confined to construction, but also long-term performance of the structure. Waterproofing is important in the below ground works to prevent water intrusion and safeguard the structure.

Waterproofing systems should be well designed to prevent future problems that may affect the space in terms of safety, durability and usability.

Another Construction Method

Health and safety are part of all our operations at CSMANLTD be it groundworks services or basement construction. Our approach to every project is based on a clear focus on risks management, proper planning, and skillful execution.

Our team is engaged in a variety of projects and we have the same standards regardless of whether we are providing early stage groundworks or providing complex below ground projects. Our technical knowledge and on-site experience work together to see to it that all works are done safely, efficiently and in high standards.

One of the biggest strides has been made in the Potomac River infrastructure development through the introduction of a tunnel boring machine called Mary. The machine has started to excavate an underground sewer tunnel of 8.8km under Washington DC as part of a long-term solution to better manage the wastewater, and minimize the effects on the environment.

The manner in which Tunnel Boring Process is done.

Gantries are attached to the machine one behind the other as the machine moves forward to create a continuous working machine within the tunnel. These systems aid in power, ventilation, transport of materials, and secure access of workers.

When complete, the machine will be approximately 1,200 tonnes, more than 200 metres long, and make a tunnel 6.4 metres in diameter. The rotating cutterhead bores the ground with crews placing precast concrete segments to create the tunnel lining.

Engineering Preparation and Launch

Contractors erected some of the main enabling works prior to the commencement of excavation and this included the construction of a 30-metre-deep shaft and starter tunnel. The front part of the machine was assembled in this space.

In the launch stage, a concrete tunnel ring was the first to be installed and attached to a thrust system, which would enable hydraulic jacks to push the machine forward and start excavation.

Alignment and Future Progress in Tunnels

The machine will proceed north of the West Potomac Park to the Georgetown University, cutting through thick bedrock. The other machine, Emily will dig in the opposite direction, thus completing the entire tunnel system.

Environmental Impact and Significance of the project

The proposed project belongs to a larger program to decrease sewage overflow into the Potomac River considerably. The development will be completed by 2030 and it will be led by a joint venture between CBNA and Halmar International.

Another Construction Way

The use of Engineering Principles in all Projects.

We know that the principles of engineering applied in big infrastructure projects are also applicable at CSMANLTD in smaller construction projects. Success in the project, be it major tunnelling or residential and commercial developments, relies on thorough planning, ground evaluation and accurate implementation.

We have had experience in below ground structures such as basements and deep foundations which guarantee stability and long-term performance. Our temporary works design and implementation help to enable safe excavations, whereas our knowledge of groundworks can enable an efficient site preparation. Moreover, our waterproofing products keep buildings dry and prevent their long-term damages.

We practice the same approach and maintain the same level of technical discipline so that all projects, big or small, are executed at the same standard of quality, safety and attention to detail.
