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
