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 ChallengesOn site

• Encroachment on road reserve– Fences– Structures

Implementation ChallengesOn site

• Utility Corridor– no corridor– Inadequate planning leads to poor usage

Implementation ChallengesOn site

• Limited road reserve– Compromise road geometry– By passes

Implementation ChallengesOn site

• Change in elevation– modification to entrances– Drainage issues

Implementation ChallengesOn site

• Geological conditions– Poor soil– Buried structures

Implementation ChallengesEnvironment

• Time lapse between design and implementation

• Change in market prices• Shortage of construction material• Culture

Implementation ChallengesContractor

• 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
