1 INITIAL STRUCTURAL INTEGRITY ASSESSMENT REPORT (SIAR) Plot & 68-73, KEPZ North Patenga Chittagong Chittagong The Alliance for Bangladesh Worker Safety Page 1/10

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 credible structural design documents available for review and kept on site? Credible and complete structural design documents were not available for review and kept on site. Have a qualified structural engineer prepare credible as-built documents based on the requirements of Part 8 Section 8.19 of the Alliance Standard. Alliance Standard Part 8 Section 8.19 Required Structural Documentation for New and Existing Factories Can credible structural documentation indicating general conformance with 2006 BNBC or other comparable applicable international model building code be produced? Provided structural documents are incomplete and don't meet BNBC 2006 standard or other comparable international code. A qualified structural engineer shall be engaged to develop the required documents to confirm the structural integrity of the buildings. Documents must comply with Alliance Standard Part 8 Section 8.19 and 8.20 Reference Alliance Standards Part 8 Section 8.2 Structural Integrity of Existing Buildings If built after 2006, can documented compliance with the seismic and wind requirements of the 2006 BNBC be provided? Design parameters are not mentioned in the available drawings. Have a qualified structural engineer document compliance with the seismic and wind requirements stated in the 2006 BNBC.

6 BNBC Part 6 Section 1.5 Can documentation be provided that the building is compliant with the requirements for wind loading and storm surge loadings as detailed in BNBC Part 6 Section 1.5.3? Design parameters are not mentioned in the available drawings. A qualified structural engineer shall be engaged to confirm satisfactory structural performance of the buildings under wind loading BNBC Part 6 Section 1.5. Compliance may be waived if the Owner provides satisfactory evidence of a cyclone operations plan that includes full evacuation of the factory in advance of any approaching cyclone" If the structure has been previously expanded, was the structural impact on the entire structure analytically evaluated and confirmed by a qualified structural engineer. Additions of undocumented canopies on both sides of 5-storied prefabricated steel production buildings (Block A) have been noticed. Visual Assessment: Visually inspected A qualified structural engineer shall be engaged to evaluate analytically the structural impact of the additional canopies on the entire framework of the production building. 15 May 2017 Reference Alliance Standards Part 8 Section 8.1 Applicability of Building Code. Have provisions been made in floors or decks for a concentrated load (such as heavy equipment, water tanks, stored materials, etc) applied at a location wherever this load acting upon an otherwise unloaded floor would produce stresses greater than those caused by a uniform load? 5-Plastic water tanks of 5000 liters capacity each have been noticed over the 4th floor of 5-Storied Prefabricated Steel Production Building (Block-A). From the study of as built architectural and structural documentation no evidence of provisions to accommodate these concentrated loads has been noticed. Document Review: Seen documents, Photograph: Picture attached Novelty Engineering Corporation shall be asked to confirm and document that provisions have been made to accommodate those concentrated loads. OR Engage a qualified structural engineer to confirm and document that provisions have been made to accommodate concentrated loads. If provisions have not been made, have a qualified structural engineer develop a remediation plan. The Alliance for Bangladesh Worker Safety Page 6/10

7 15 May 2017 Alliance Standard Part 8 Section 8.13 and 8.14 Where density of operations, storage of materials, or equipment weights require live load capacity in excess of 2.0 kn/m2 (42 psf), do the design documents confirm that the required load capacity exists? Or has the load capacity been analytically confirmed and certified by an Alliance-qualified structural engineer? Materials storage over loading in excess of 63 psf (as per DEA) has been noticed in 5-Storied prefabricated Steel Production Building (Block-A). Photograph: Photo attached, Visual Assessment: Visually inspected Storage loading shall be kept within acceptable loading limits. 15 May 2017 Alliance Standards Part 8 Section 8.15 Minimum Floor Design Loads Are Certificates of Occupancy available for review? Low No certificate of occupancy is available. It is necessary to provide approved certificates of occupancy from local authority. Alliance Standard Part 8 Section 8.3 Preliminary Structural Assessment Structural System Construction Have all areas of needed maintenance, including areas with efflorescence, dampness, standing water on rooftops, and corrosion been addressed. Dampness has been noticed in 5-Storied Prefabricated Steel Production Building (Block-A), 4-Storied Rc Restaurant Building attached with a one storied shed with Metallic roof covering major areas and Rc Roof Over Penthouse and 1-Storied Rc Power Room.

Photograph: Picture attached Complete further testing on areas of deterioration and have a qualified structural engineer develop a remediation plan. 15 May 2017 Alliance Standard Part 8 Section 8.26 Are all non-structural elements suspended from, attached to, or resting atop the structure adequately anchored and braced to resist earthquake forces? No anchoring and bracing are used in Racks to resist earthquake forces. Visual Assessment: Visual inspection. Racks shall be adequately anchored and braced to resist earthquake force as per BNBC and Alliance Standard. Alliance Standards Part 8 Section 8.18 Seismic Bracing of Key Non-Structural Elements and 2006 BNBC Part 6 Structural Safety Programs Is a program in place to ensure that the live loads for which a floor or roof is or has been designed will not be exceeded? No load management program is currently in place., Visual Assessment Develop a program to ensure that all live loads for which a floor or roof has been designed for will not be exceeded. The designated Load Manager shall oversee this program and ensure it is enforced. Alliance Standard Part 13 Section 13.7 and Part 8 Section 8.9. Have Load Plans been prepared for each floor documenting the actual maximum operational loading that is intended and/or allowable on each floor. The Alliance for Bangladesh Worker Safety Page 8/10
