Foundation and Precision Setup

• Ground slabs laid to detailed specifications.
• Kicker placement guides precise tunnel form installation.
• Wall reinforcements set with exactness.

Concrete Pouring and Insulation

• Reinforcement for slabs installed, with preparations for subsequent levels.
• Comprehensive checks ensure readiness for concrete pouring
• Insulation measures applied for concrete setting in varied climates.

Formwork Placement and Assembly

• First Half-Tunnel set is placed by crane, aligned with precision.
• Window/door openings and electrical conduits integrated seamlessly
• Second Half-Tunnel unit placed, ensuring perfect vertical alignment.

Systematic Dismantling and Progression

• Post-concrete heating facilitates curing, with dismantling commencing the next day.
• Tunnel units cleaned, oiled, and moved for the next cycle
• Continual progression with reinforcement in place for the next phase.

Formwork Securing and Site Preparation

• All tunnel form units are methodically aligned for concrete pouring.
• Tie-rods secured, horizontal surfaces prepared for concrete.
• Essential components for slabs and walls are meticulously positioned.

Finishing and Cycle Repetition

• Surfaces treated post-stripping for quality preservation.
• Back propping supports the structure as the cycle repeats.
• Efficient transition to the next level with strategic formwork management.

Advantages of Tunnel System

Improved safety:

• The tunnel form work system can improve safety on the construction site . This is because the form work is enclosed , which helps to protect workers from falling objects and other hazards. as it reduces the need for workers to work at heights.

Efficient Use of Materials:

• The tunnel form work system can help to improve the efficiency of material usage . This is because the form work is reusable , which reduces the amount of waste that is produced .

High-Quality Finishes:

• The tunnel form work system produces high – quality concrete finishes that require minimal finishing . This is because the form work is made from smooth materials that do not absorb moisture , which helps to prevent the formation of cracks.

Reduced Laborcosts:

• The tunnel form work system requires less labor than conventional methods. This is because the form work is prefabricated and can be easily assembled and disassembled by a small team o f workers.

Fast Construction Speeds:

• The tunnel form work system can significantly reduce construction times compared to conventional methods. This is because the walls and slabs are cast in one operation , which eliminates the need for time – consuming form work stripping and re-setting .

Accuracy:

• The system is very accurate, which reduces the need for rework.
