Project: Dublin Port 

Dublin Port 

Berth 35 development had more than 1,000 tonnes of modular rebar, a 300-tonne pile cap 3 meters deep was installed in 7 days working against the tide.  

Client

Roadbridge 

Problem

1. The multiple layered design required on both bottom and top layer of reinforcement.  
2. Working with the tide 

Solution

1. BIM. Due to the congestion of both bars on both layers of the slab, clash detection was vital for productivity. Not only was productivity increased, health and safety concerns and potential accidents have been avoided on this project by using Tekla software due to identifying risks before any bars have been fabricated. 
2. Midland Steel have been using Tekla software for over 10 years to detail modular solutions. By following the FasterFix process, a modular solution was detailed to incorporate the number of layers of rebar required into cages and one way meshes. With a pump running 24/7 to keep the foundation from flooding, the installations had to be optimized at low tides with concrete pours planned as soon as the last cages had been positioned.  

Project Details

This raft slab is to act as a counterweight for the new docking area at Dublin Port. The 29m long, 16m wide and 3m deep slab had a total of 285 tonnes of reinforcing steel all detailed using Midland Steel’s FasterFix Modular Rebar process. Detailed, delivered and installed modularly, this large raft slab was installed, backfilled, and poured in eight working days saving between 4-6 weeks on the construction programme in comparison to traditional steel fixing.
