1 INITIAL STRUCTURAL INTEGRITY ASSESSMENT REPORT (SIAR) Assessor: Plot M-4/3, Road 7, Section 7 Mirpur, Dhaka Dhaka Dhaka Bangladesh Emkay Enterprises The Alliance for Bangladesh Worker Safety Page 1/7

2 Introduction to the Report The following report contains a site profile and summary of non-conformities identified during an onsite assessment commissioned by the Alliance for Bangladesh Worker Safety (Alliance) and conducted by a third-party Qualified Assessment Firm (QAF). The assessment was conducted against the Alliance for Bangladesh Worker Safety Assessment Protocols (APs) and Fire Safety and Structural Integrity Standard, which is harmonized with the factory assessment guidelines developed by Bangladesh University of Engineering and Technology (BUET) for the Bangladesh National Tripartite Plan of Action (NTPA). The goal of the Alliance process is to provide clear and practical technical requirements by which Bangladeshi Ready Made Garment (RMG) Factories producing for Alliance members may be consistently and fairly evaluated for fire, structural, and electrical safety in a non-duplicative manner. Each assessment will prompt action plans that will be used by RMG factories to systematically and sustainably improve safety conditions for garment workers. Beyond tracking and reporting on action steps taken in a transparent manner, the Alliance organization and its members will seek to further support factory improvements through technical assistance, training, implementation support for functional Worker Committees, and in some cases financial assistance and wage support for workers if factories are closed for remediation. The contents of the report do not constitute a guarantee of compliance with the applicable laws, the Alliance Standard or the absolute or continued safety against fire, electrical and/or structural integrity issues that may lead to injury or loss of life. The report is designed to provide a non-exhaustive summary of risk issues, based on a limited sampling and duration of time onsite by the named QAF. Neither the QAF nor the Alliance can certify or guarantee the quality, outcome, or effectiveness of actions taken in response to the report.

5 ASSESSMENT FINDINGS Structural System Design Are the available FoS for the columns adequate based on Preliminary calculation? High Non-Compliance Level: 3 FoS calculations were completed assuming an average live load of 42 psf for working area. A 40 ksi reinforcing steel strength was assumed according to design documents. FoS calculations were originally completed assuming a concrete compressive strength of Uploaded Document: 1. FoS calculation of Tunic Apparels Ltd. 2. Core test reports-tunic Apparels Ltd. 3. Equivalent Concrete Core Strength Calculation. Submit the previously conducted Bureau Veritas detail engineering assessment (DEA) report to the Alliance for review and approval as a DEA has already been completed from the factory end. Provide results of preliminary calculations in space provided. a) column capacity; FoS > Safe b) column capacity; FoS Needs Evaluation c) Column capacity; FoS Needs Evaluation d) Column capacity; FoS < Unsafe In case of a critically low FoS (<1.25), consider Immediate Escalation Protocol Are credible structural design documents available for review and kept on site? Medium Structural design document available and kept on site. But some column section for upper floor does not match with the provided structural drawing. Visual Assessment: Structural design document available and kept on site. But some column section for upper floor does not match with the provided structural drawing. Have a qualified structural engineer prepare credible as-built documents based on the requirements of Part 8 Section 8.19 of the Alliance Standard.

7 Is the building free of active signs of water intrusion or ponding due to lack of performance of the façade system? Low Though water intrusion or ponding was not found during visual assessment, some wall found unplaster at outside face which can make the wall damp in future.
