Buriganga (Phase 2) Project, BIWTA
Recently EIMS is involved in the Buriganga Development Project (Phase 2) under the Bangladesh Inland Water Transport Authority (BIWTA) as a Consultant to plan and design of river bank demarcation pillar, a pedestrian walkway along the river bank line, facilities, and structural design of jetty along with work on evicted foreshore land, quay wall for bank protection and pedestrian walkway bridge.
In this project, a total 52 km length of the pedestrian walkway and quay wall along the bank of the Buriganga River will be constructed in the 1st phase of this project to project the riverbank against the river erosion and beautification of river side. Later on, the
quay wall and pedestrian walkway will be extended for the Turag, Balu, and Shitalakya Rivers.
To demark the riverbank against the illegal land acquiring at the riverside around 10800 demarcation pillars will be constructed. Currently, the layout and marking up of the pillar location is in progress. To enhance the beauty of the riverbank and continuation of the walkway a pedestrian bridge and 3 eco-parks will also be constructed. Moreover, a total of 11 jetties will be planned and design to facilitate the loading and unloading of river transportation vessels. To understand the project some of the project layouts are shown in the following figures.

Jhilmil Residential Area Apartment Project
Jhilmil Residential Park is the prodigious residential project is under Public Privet Partnership (PPP). Environment & Infrastructure Management Solution (EIMS) Limited was assigned as structural and geotechnical design consultant. The purpose of this project is to reduce the acute problem of housing in Dhaka by buildings 71 nos. twenty (20) storied buildings and 14 nos. twenty-five (25) storied buildings inside the Jhilmil Residential Park Project area.
The lateral-force-resisting system consists of ordinary reinforced concrete shear walls. All the components
of the structure have been designed to achieve economy and constructability that provide adequacy against hazards and ultimate human comfort conforming the code provisions of Bangladesh National Building Code (BNBC) 2020.
The construction method for this project is Industrial Building System (IBS) which is a new-fangled technology in the context of Bangladesh's engineering practice. This system offers economy by the taking advantage of the repetitive use of the formworks that results in lest time cost.
LEARNING CENTER
During the second half of 2017 an estimated 687,000 Rohingya across the Myanmar border drove into Cox's Bazar, Bangladesh. The Education sector response plan estimated that over 450,000 children aged between 4-18 years old in Cox's Bazar need access to education services. UNICEF aims to have built a total of 1,453 LCs by 2018. However, the areas of Cox's Bazar are experiencing lots of natural disasters such as Earthquake, cyclones, flood due to heavy rainfall etc. which are a great threat for the existing structures. That's why the education sector wants to have more safe, durable and disaster resilience structures as well as structures those are feasible for different topography in Cox's Bazar for learning centres.
Team EIMS took this challenging job in getting alternative learning centre designs in existing camps and new camps in Cox's Bazar district. The main challenge was to select material for low-cost and easy construction along the climatic challenge it must withstand in that area. Team EIMS proposed low to high hazard design options in terms of durability, topography and location considerations.
DEVELOPMENT OF RESIDENTIAL PROJECTS
Tozammel Residence is a recently completed apartment building in the Rangpur city. It's a six storied building designed on 303.53 SQM land.
EIMS is now working in the development of residential projects. One of the ongoing Projects is 9 storied apartment building at G block,Bashundhara Residential Area. The land area is 5 katha. EIMS also provides its clients with relevant approval drawings such RAJUK sheet.
VULNERIBILITY ASSESSMENT
EIMS offers building vulneribility assessment of existing structures with experienced assessors and modern tools & techniques. Within a short period, EIMS has conducted initial intrigity assessment over 200 buildings and conducted detailed structural vulnerability assessment of over 100 buildings. Besides this, EIMS has been selected as “Qualified Structural Assessment Firm for the Alliance for Bangladesh Workers' Safety”, Department of Inspection for Factories and Establishments (DIFE). Quality assessments provided by EIMS are:
- Preliminary vulnerability assessment as national and international standards (ASCE 41, FEMA 154).
- Non-linear analysis (ASCE 41 Tier 3) and retrofitting design of existing structures for seismic vulneribility assessment.
INITIAL STRUCTURAL INTEGRITY ASSESSMENT
- EIMS has successfully completed Initial Structural Integrity Assessment of thirty-Seven (37) factory buildings under ALLIANCE for Bangladesh Worker Safety.
- Structural integrity assessment by Visual inspection (Type-C) on three garments building (FS-SFB#3, FS-SFB#5, FS-SFB#6) of Hop Lun (BD) Ltd. at DEPZ, Ganakbari, Savar, Dhaka.(Detail Structural Analysis is recommended for the garments buildings).
