CFRP strengthening at HDF
Project overview
Client: HDF
Consultant: Eng. Maroun Abdel Ahad
Status: Completed on October 2019
Location: Achrafieh, Beirut
Scope of Work
The project aimed to increase the load-bearing capacity of existing slabs and beams to accommodate upgraded usage requirements and additional imposed loads, while maintaining uninterrupted hospital operations.
The strengthening works focused on improving the structural performance of reinforced concrete slabs and beams.
1. Structural Assessment & Preparation
- Detailed inspection of existing structural elements
- Identification of deficient zones
- Surface preparation to required roughness (CSP standards)
- Removal of weak or deteriorated concrete
2. Substrate Preparation
- Mechanical grinding and cleaning of concrete surfaces
- Ensuring proper bonding conditions
- Moisture and contamination control
Key Challenge
Executing structural works inside a hospital environment required strict control measures and careful planning.
Main Constraints:
- Continuous hospital operation (no shutdown allowed)
- Presence of patients, medical staff, and sensitive equipment
- Restricted working hours and controlled access zones
- Noise and vibration limitations
- Dust control and hygiene requirements
Our Approach:
- Phased execution with clearly defined work zones
- Night and off-peak working schedules where required
- Use of low-noise and low-vibration equipment
- Full dust containment systems and protection barriers
- Continuous coordination with hospital management
