Columns appear to be stressed to levels that require immediate review

Observations

4Observations

Testing confirmed Stone aggregate in ground floor columns.

• Columns indicated in red appear to be stressed to a degree that requires immediate review.

• Calculations indicate that other columns are also stressed in excess of design limits.

5

Concrete water tank located on roof

Toilet Build up

• Raised toilet floors to gents toilets over 3 floors (300-400mm on top of concrete slab), and a concrete water tank located at roof level, contribute to columns being stressed to levels that require immediate review

6

Cracking to top of floor slabs

7

Diagonal cracking was observed on the top of the floor slab around perimeter columns where the floor finish had been removed.

Cracking visible in floor slab

Design check required for plinth loading in toilet areas to confirm flat slab load

capacity

13

Toilet Build up

• Raised toilet floors to gents toilets over 3 floors.

• 300-400mm on top of concrete slab will exert load greater than that in the general factory area.

Priority Actions

19

Problems Observed

1. Columns appear to be stressed to levels that require immediate review

2. Cracking to finishes on top of floor slabs3. Design check required due to discrepancies between ‘as-

built’ drawings and building structure – location of stairs, location and size of cantilevers, number of bays etc.

4. Design check required for plinth loading in toilet areas to confirm flat slab load capacity

5. Load management of storage loads6. Cracking at expansion joint

Item No. Observation Recommended Action Plan Recommended Timeline

1Columns appear to be

stressed to levels that require immediate review

Reduce loading in area shown on drawing above to 1.5kPa at 2nd, 3rd and 4th floors, and to Zero at 1st, 5th and 6th floors.

Immediate - Now

2Columns appear to be

stressed to levels that require immediate review

In all other areas, limit load to 2kN/m2 at all levels. Immediate - Now

3Columns appear to be

stressed to levels that require immediate review

Empty water tank on roof. If this water tank is a fire water tank, ensure measures are taken to provide adequate water supply in the event of a fire.

Immediate - Now

4Columns appear to be

stressed to levels that require immediate review

Factory Engineer to review design, loads and columns stresses in area identified above.

Immediate - Now

5Columns appear to be

stressed to levels that require immediate review

Verify insitu concrete strengths (using min. 4 no. 100mm dia. cores) and existing reinforcement for all columns.

Immediate - Now

6Columns appear to be

stressed to levels that require immediate review

A Detail Engineering Assessment of Factory to be commenced, see attached Scope.

Immediate - Now

7Columns appear to be

stressed to levels that require immediate review

Produce and actively manage a loading plan for all floor plates within the factory giving consideration to floor capacity and column capacity. This should include a safe level to which any water tanks can be filled.

This Schedule develops a minimum level of information, Analysis and testing expected as part of a Detail Engineering Assessment.The Building(s) have been visually assessed and it is deemed necessary that a detailed engineering assessment be carried out by a competent Engineering Team employed by the factory Owner. This Request should be read in conjunction with the BUET developed Tripartite Guideline document for Assessment of Structural Integrity of Existing RMG Factory Buildings in Bangladesh (Tripartite Document), the latest version of this document should be referenced. T his document also gives guidance on required competency of Engineering Team.

We expect that the following will be carried out:1. Development of Full Engineering As-Built Drawings showing Structure, loading, elements, dimensions , levels, foundations and framing on Plan,

Section and Elevational drawings .2. The Engineering team are to carry out supporting calculations with a model based design check to assess the safety and serviceability of the building

against loading as set out in BNBC-2006, Lower rate provisions can be applied in accordance with the Tripartite Guidelines following international engineering practice, justification for these lower rate provisions must be made.

3. A geotechnical Report describing ground conditions and commenting on foundation systems used/proposed.4. A report on Engineering tests carried out to justify material strengths and reinforcement content in all key elements studied.5. Detailed load plans shall be prepared for each level showing current and potential future loading with all key equipment items shown with associated

loads.6. The Engineering team will prepare an assessment report that covers the following:

• As-Built drawings including• Plans at each level calling up and dimensioning all structural components • Cross sectional drawings showing structural beams, slabs, floor to floor heights, roof build-ups and Basic design information of the

structure• Highlight any variation between As-built compared to the designed structure• Results of testing for strength and materials• Results of geotechnical assessment and testing/investigation• Details of loading, inputs and results of computer modelling• Commentary on adequacy/inadequacy of elements of the structure• Schedule of any required retrofitting required for safety or performance of Structure

Any proposals for Retrofitting to follow guidance developed in the Tripartite Document
