Construction Work Methodology for Renovation and
Expansion works of Dubti Regional Laboratory
1. INTRODUCTION
This method of statement is prepared based on the information collected during the site visit
Based on the data collected, during the site visit, we have prepared our report to outline how this
project will be constructed, comprising schedule/program/ and detail means of performing each
key activity, whose cumulative effect is completion of the project within the expected quality
and time frame. It also clearly states who is going to be engaged, what and when supports from
external stakeholders are needed. Potentially significant environmental impacts associated with
these activities are identified and where necessary, proposals for mitigation are outlined.
2. PROJECT OVERVIEW
Project Title: Renovation and Expansion works of Dubti Regional Laboratory
Location: Dubti Town, Afar Region
Duration: 365 Calendar days
3. OBJECTIVE
This document outlines the methodology for executing Renovation and Expansion works of
Dubti Regional Laboratory. The primary objectives are to:
Rectify Defects: Conduct critical maintenance to repair and upgrade structural, roofing,
sanitary, electrical, electromechanical and miscellaneous works.
Improve Safety & Hygiene: Upgrade facilities to meet health and safety standards,
ensuring a safe working environment.
Minimize Disruption: Execute works in phases to allow the buildings to remain
operational throughout the project.
Utilize Local Resources: Maximize the use of locally available materials and skilled
labor to support the local economy and ensure sustainability.
To carry out timely and safe renovation and upgrading work on the existing facilities, ensuring
minimal disruption to ongoing services and compliance with Ethiopian building codes and
standards.
3.1 Site-Specific Considerations
3.1.1 Local Material Availability: The methodology prioritizes materials readily
available in the region or from major hubs like Addis Ababa to reduce cost, lead time,
and carbon footprint.
o Concrete: Use locally sourced cement, sand, and aggregate.
o Masonry: concrete blocks.
o Timber: Locally sourced, seasoned timber for formwork and minor structural
elements.
o Finishes: Local plaster, paint, and ceramic tiles.
3.1.2 Climate :
o Rainy Season (June - September): Work schedules will be flexible. Critical
outdoor work will be planned for the dry season. Temporary weather protection
(tarpaulins) will be used.
o Dry Season (October - May): Optimal period for major works, plastering, and
painting. Dust control measures (water spraying) will be implemented.
Temperature: Work will start early to avoid the midday heat. Adequate hydration breaks will be
mandatory for workers.
4. METHODOLOGY
5.1 Pre-construction Activities (A Week)
Site Assessment & Planning

5.4 Final Fix, Commissioning & Handover (A Week)
Final Fix: Install light fixtures, switches, sockets, tap fittings, and accessories.
Testing & Commissioning: Test all electrical circuits, water flow, drainage, and door
hardware.
Deep Clean: Conduct a thorough clean of the entire area.
Snagging: Identify and rectify any minor defects.
Client Walkthrough & Handover: Conduct a formal handover with the management,
providing all necessary warranties, certificates, and as-built documentation
5. Health, Safety, and Environmental (HSE) Management
5.1 Safety Protocols:
Personal Protective Equipment (PPE): Hard hats, safety boots, high-visibility vests,
gloves, and dust masks are mandatory on site.
Site Security: The site will be secured with fencing to prevent unauthorized access,
especially by children.
Working at Height: Use of proper scaffolding or certified ladders for roof work.
Harnesses will be used for edge protection.
Hazardous Materials: Safe handling and storage of fuels, oils, and chemicals. No
asbestos is assumed; if suspected, work will stop immediately for specialist assessment.
Tool Safety: All power tools will be inspected and used with correct guards and PPE.
Excavations: All trenches deeper than 1.2m will be properly shored or battered back.
First Aid: A fully stocked first aid kit will be available on site at all times. Key personnel
will be first-aid trained.
5.2 Health Center Specific Safety:
Infection Control: Minimize dust generation. Seal work areas from operational zones.
Noise: Noisy work will be scheduled for agreed-upon times to avoid disturbing patients.
Access: Maintain clear and safe access to construction entrance and emergency exits at
all times.
5.3 Environmental Management:
Waste Management: Reduce, reuse, and recycle materials. Dispose of all construction
waste legally and responsibly.
Water Management: Avoid contaminating local water sources. Control silt run-off from
the site during rains.
Energy & Water: Use energy-efficient tools and minimize water wastage on site.
5.4 Environmental Considerations
Use locally available, sustainable building materials
Avoid contamination of water sources with construction runoff
Minimize construction waste and promote recycling where possible
5.5 Coordination with Health Center Operations
Daily coordination meetings with facility management
Schedule disruptive works (e.g., noisy or dusty tasks) during off-peak hours
Maintain separate access routes for construction workers
Install temporary barriers and warning signs
5.6 Quality Control
Implement inspection and testing for all works (especially plumbing and electrical)
Follow project specifications and Ethiopian Building Code standards
Maintain detailed site records and progress reports
Obtain approvals for each phase before proceeding
6. PROJECT TEAM AND COMMUNICATION
Site Supervisor: Responsible for daily operations, quality control, and safety.
Local Skilled Labor: Masons, carpenters, electricians, plumbers.
General Labor: Sourced locally.
Communication: Daily coordination meetings with the site team. Weekly progress
meetings with the responsible management.
7. PROJECT HANDOVER
Conduct final inspection with client and relevant authorities
Prepare and submit:
o As-built drawings
o Operation and maintenance manuals
o List of installed equipment and warranties
Provide training to facility maintenance staff (if needed)
Official handover and sign-off
8. TIMELINE AND PHASING
Work shall be executed in phases,
A detailed Gantt chart shall be submitted separately.
9. CONCLUSION
This methodology aims to ensure that Renovation and Expansion works are completed
efficiently, safely, and with minimal impact on day to day services. All works shall comply with
local building codes, Ministry of Construction requirements, and environmental and safety
standards.
