DESIGN PHASE
Design Phase (Feasibility Study and Tendering)
• Report submissions
– Preliminary Assessment Report
• Highlights the problems, challenges & deficiencies with
its current usage
– Environmental and Social Impact Assessment
Report
• Continuous engagement of stakeholders
• Compliance with the regulations of the EPA
Design Phase (Feasibility Study and Tendering)
– Project Selection Report
• Appropriate remedy to address problems, taking into
account stakeholders need, appropriate standards and
guidelines, sound engineering principles of safety,
economic benefits verses cost of implementation
– Draft and Final Design Report
• Comprehensive reports, including drawings, bills of
quantities
– Pre-bidder Conference
Design Challenges
• Inadequate record Keeping
• Loss of institutional Knowledge
• Missing road survey plans / road reserve /
acquisition
• Culture of People / poor enforcement
• Inter agency coordination
• Underground utilities / structures
Design Challenges
• Site Conditions – Swamp, water
• Budget Constraints – availability, most
economic (design / supervision / construct)
• Weight Control
• Competitive pricing – Tendering stage
• Attracting new contractors – Tendering stage
• Contractor overload – Tendering stage
implementation PHASE
Construction Stage
• Reports
– Project Design Review
• Review of design
– Review Report of Contractor QA/QC plan
• Review contractor’s submission
– Monthly Progress Reports
• Captures progress of works, issues, etc
Construction Stage
– Work Program
• To be used by the contractor to plan & execute the
works
• Initial program (First 3 months)
• Accepted Programme (entire work)
• Updated Programme (t least on monthly basis)
– Method Statement
• Same time with programme
• General description of the arrangements and methods
of construction and temporary works design
• The statement should be fully cross-reference to the
activities in the programme
Implementation Challenges
On site
• Encroachment on road reserve
– Fences
– Structures
Implementation Challenges
On site
• Utility Corridor
– no corridor
– Inadequate planning leads to poor usage
Implementation Challenges
On site
• Limited road reserve
– Compromise road geometry
– By passes
Implementation Challenges
On site
• Change in elevation
– modification to entrances
– Drainage issues
Implementation Challenges
On site
• Geological conditions
– Poor soil
– Buried structures
Implementation Challenges
Environment
• Time lapse between design and
implementation
• Change in market prices
• Shortage of construction material
• Culture

Frequent down time
Inadequate human resources
Equipment fleet
Poor planning / lack of planning tools
Procurement of materials
Quality / time Control
Use of Mobilization Advances
Traffic / Safety Management
Social Engagement
Recommendations
• Materials Management Unit (Government
level)
• Government roster with upcoming work
projects in all areas
• Better contractor register – Database
• Procurement / Evaluation Criteria
• Improved Public Relations
• Multi stakeholders Committee throughout the
project cycle
Recommendations
• Common spatial database for utilities
• Review and enforcement of weight control
• Establishment of equipment pool – renting of
specialised equipment
• Value Engineering
