1 Current Design and Implementation Challenges of Road Projects on the Coastland
Ron Rahaman Chief Roads and Bridges Officer Ministry of Public Works Works Services Group

2 Project Life Cycle Project Manager Starting the Project Conceptualized
Team Employer Organising & Preparing Feasibility, Planning & Design Consultant Stakeholders Carrying out the works Construct Sponsor Closing the project Contractor Test & Turnover

3 DESIGN PHASE

4 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

5 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

6 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

7 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

8 implementation PHASE

9 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

10 Construction Stage Work Program Method Statement
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

11 Implementation Challenges On site
Encroachment on road reserve Fences Structures

12 Implementation Challenges On site
Utility Corridor no corridor Inadequate planning leads to poor usage

13 Implementation Challenges On site
Limited road reserve Compromise road geometry By passes

14 Implementation Challenges On site
Change in elevation modification to entrances Drainage issues

15 Implementation Challenges On site
Geological conditions Poor soil Buried structures

16 Implementation Challenges Environment
Time lapse between design and implementation Change in market prices Shortage of construction material Culture

19 Implementation Challenges Contractor
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

20 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

21 Recommendations Common spatial database for utilities
Review and enforcement of weight control Establishment of equipment pool – renting of specialised equipment Value Engineering
