2 Identified Priority 1 Concerns

3 1 st Priority 1 Concern This column was checked. The Ferroscan image gives a result of 16 bars in this column. Columns possess very low factors of safety Based on the drawings and the Ferro-scan result, the column reinforcement appears to be consistent with the rebar arrangement at ground level. According to the load rundown calculation, typical columns have been found to possess very low factors of safety with regard to their load carrying capacity, thus giving an AMBER warning. Therefore, we require further action and investigation to be carried out as noted at the priority actions a DEA. The building was constructed in 1997 with stone aggregate and high strength steel as informed in asbuilt drawings. However, a DEA needs to be carried out to verify this information.

4 Identified Priority 3 Concerns

5 1 st Priority 3 Concern On the 9/F ceiling (the roof slab), there are many areas where water seepage has caused water damage leading to loosening of plaster. In other areas; such as the ceiling below the toilets at the rear of the building on each floor also exhibits water damage (6/F). On some floors, walls also have water damage (4/F). This should be repaired and prevented from happening again. Water ingress has caused water damage at several locations

6 2 nd Priority 3 Concern From the picture, it may be concluded that no waterproof membrane has been applied at the roof level of the building. This means that any cracks in the surface finishes on the roof will allow water to seep into the concrete slab beneath the finishes, and cause long-term soaking of the slab, causing the defects as observed on 9/F ceiling. Roof Floor does not appear to have any proper waterproof membrane to protect lower floor from water damage

7 Priority Actions

8 Problems Observed Summary ITEM 1: (1 st Priority 1) Preliminary load take-down calculation found that some typical columns possess the marginal spare loading capacity. ITEM 2: (1 st Priority 3) Several areas at 9/F (roof) have significant water damage at wall and ceiling locations. ITEM 3: (2 nd Priority 3) the roof floor appears not to have any proper waterproofing layer.

9 Item No. Observation Recommended Action Plan Recommended Timeline 1 Carry out a partial Detailed Engineering Assessment of the entire 1st Priority 1 - Preliminary load take-down calculation building including any intrusive testing required. found that some typical columns possess the marginal spare The Factory Engineer to review design, loads and columns stresses in loading capacity. the building in accordance with BNBC regulations. Prepare and produce the loading plans for all floors 6-weeks 2 1st Priority 1 - Preliminary load take-down calculation found that some typical columns possess the marginal spare Continue to strictly maintain loading plan. loading capacity. 6-months 3 1st Priority 3 - Several areas at 9/F (roof) have significant water damage at wall and ceiling locations. Provide temporary propping to the damaged concrete areas (slabs and beams). 6-weeks 4 1st Priority 3 - Several areas at 9/F (roof) have significant water damage at wall and ceiling locations. Hack away the damaged plaster and concrete and expose reinforcement to check for corrosion. Carry out replacement of reinforcement and suitably repair all structural elements as necessary. 6-months 5 2nd Priority 3 - The roof floor appears not to have any proper waterproofing layer. Remove the existing screed, applying a new waterproofing membrane and re-applying the screed if necessary. The repair works should be carried out under dry conditions, to avoid trapping of air or water pockets which would affect the effectiveness of the waterproofing. 6-months
