1. The virgin ground is being excavated to create a manhole pit, and the hydraulic jack is placed at a strategic spot. The size and depth of the manhole pit varies, depending on the specification requirements.

2. The pipes strings are stringed together piece by peice using the hydraulic jacking machine. Each unit of pipe are being lifted down into the manhole pit by a crane. The jacking of pipes towards the destined direction is done from the launch shaft to the target shaft.

3. Brightway Slurry Separation System is essential in different soil with different ground water levels. In the cutter head, the excavated spoil is mixed with water and then transported to the surface, where water and spoil are separated by the separation plant and the clean water then remains in the slurry circle.
Brightway unique separation plant can operate in different models depending on the ground condition.

4.Lastly, once the string of pipes are done, the crane will then, remove the cutter head from the manhole pit at the target shaft, and replace the gap with a connecting pipe inside. Both manhole pits will be sealed with cement seamlessly.
