1 EQUIVALENT INITIAL STRUCTURAL SAFETY ASSESSMENT Factory Tetulzhora Union, Hemayetpur, Savar Savar Dhaka 01 Mar 2014 The Alliance for Worker Safety Page 1/10

2 01 Mar 2014 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 Worker Safety (Alliance) and conducted by a third-party Qualified Assessment Firm (QAF). The assessment was conducted against the Alliance for Worker Safety Assessment Protocols (APs) and Fire Safety and Structural Integrity Standard, which is harmonized with the factory assessment guidelines developed by University of Engineering and Technology (BUET) for the National Tripartite Plan of Action (NTPA). The goal of the Alliance process is to provide clear and practical technical requirements by which i 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 01 Mar 2014 ASSESSMENT FINDINGS Structural System Design Is a clear and redundant load path to resist lateral loads provided? The main factory building is designed as three separate buildings, but it is constructed as a single building. Therefore, the lateral load path is changed and also its lateral load path is not clear and redundant. Document Review: Confirmed by reviewing structural drawings. Have a qualified structural engineer complete further analysis of the structure and develop a remediation plan if required. Alliance Standards Part 8 Section 8.17 Design for Lateral Loads and BNBC Part 6 Section 1.5 Are credible structural design documents available for review and kept on site? Non-Compliance Level: 2 A set of structural design document is available on-site for review. However, the design report is not available which is required as per BNBC 2006 clause Document Review: Design report unavailable. Have a qualified structural engineer prepare credible as-built documents based on the requirements of Part 8 Section 8.19 of the Alliance Standard.

6 01 Mar 2014 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? Non-Compliance Level: 2 There are 4 plastic water tanks, 2 having capacity of 3 tons and 2 having capacity of 1 ton of water storage. Also, transmission tower found in 7th floor roof. There is no analytical information on the provision of these additions in the building design. Document Review: No analytical information availble., Visual Assessment, Document Review: No analytical information availble., Visual Assessment 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. Alliance Standard Part 8 Section 8.13 and 8.14 Are Certificates of Occupancy available for review? Low Non-Compliance Level: 1 The Certificate of Occupancy is not available. Document Review: Document unavailable. Provide Certificates of Occupancy for review. 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. Non-Compliance Level: 2 Standing water have been found at 1st floor north-east corner and dampness has also been found at 4th floor of the building. Corrosion was also observed in roof top rebars of columns. The Alliance for Worker Safety Page 6/10

7 01 Mar 2014 Visual Assessment: Visually confirmed. Under guidance from a qualified structural engineer, address all areas of needed maintenance by correcting the identified issues. Alliance Standard Part 8 Section 8.26 Durability and Maintenance Are any structural elements constructed with MCAC exposed to rainfall or other sources of water sealed with a protective coating to prevent water intrusion? Non-Compliance Level: 2 The roof of the building is of MCAC aggregate but no protective sealing is available. Visual Assessment: Visually the roof of the building is of MCAC aggregate but no protective sealing is available. Provide a protective coating at the structural elements constructed with MCAC exposed to rainfall or other sources of water. Have protective coating approved by the Alliance or a qualified structural engineer. Or provide 2% slope on the exposed surface to Alliance Standards Part 7 Building Materials Section 7.2 Masonry-chip aggregate concrete (MCAC). Are all non-structural elements suspended from, attached to, or resting atop the structure adequately anchored and braced to resist earthquake forces? Non-Compliance Level: 2 In the store rooms of ground, 1st, 5th and 6th floors, there are racks which are not braced for earthquake force. There are 4 plastic water tanks with considerable height which are not braced or anchored properly. Visual Assessment: Visual inspection shows that in the store room of ground, 1st, 5th and 6th floor, there are racks which are not braced for earthquake force. There are 4 plastic water tanks with considerable height, which are not braced or anchored prop Adequately anchor and brace all non-structural elements to resist earthquake forces to comply with the BNBC and Alliance Standard. 15 Sep 2014 The Alliance for Worker Safety Page 7/10

8 01 Mar 2014 Alliance Standards Part 8 Section 8.18 Seismic Bracing of Key Non-Structural Elements and 2006 BNBC Part 6 Are structural steel members free of corrosion, physical damage or other types of deterioration? Non-Compliance Level: Apply protective coating on steel members. Alliance Standard Part 8 Section 8.26 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? There is no program that will ensure that the designated load in each floor will not be exceeded Document Review: Confirmed by reviewing documents. 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. 21 Jul 2014 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. Low Load Plans includs the actual maximum operational loading that is intended and/or allowable on each floor. However, the load plans provided by Aboni Knitwear only includes the existing loading condition of the floor. Also, they do The Alliance for Worker Safety Page 8/10

9 01 Mar 2014 not include the scaled layout of workstations, operating equipment. Document Review: Confirmed by reviewing documents. Have a qualified structural engineer develop Floor Loading Plans per the requirements of Part 8 Section Alliance Standard Part 8 Section 8.10 Floor Loading Plans (Load Plans) Are Floor Load Plans posted as required? Low Load plans have been prepared but not as per Alliance standard. Visual Assessment: Visual assessment shows that load plans have been prepared but not as per Alliance standard. Have a qualified structural engineer prepare load plans including the information required in Section 8.20 of the Alliance Standard. Alliance Standard Part 8 Section Are areas used for storage of work materials and work products, clearly marked to indicate the acceptable loading limits as described in the Load Plan for that floor? Low Available load plans do not comply with the standard. Loading limits are not mentioned in the provided load plans.
