My Last Working Day on 25th November 2003 (Kashmere Gate Station in the Background)
![Page 54: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/54.jpg)
Founding Principles of Delhi Metro Construction Management
No hoardings reading
– “Inconvenience is regretted”,
– “Work in Progress”,
– “Please bear with us”
These hoardings indicate poor planning and callous approach
They are indicators to future accidents, time overruns and cost overruns
![Page 55: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/55.jpg)
Founding Principles....
A new project brings new investment
Agency developing the infrastructure is in a better position to manage civic services at site
Hoardings at work sites on street should
– be a welcome sign
– public should expect better roads, smoother traffic and safer environment
– be a brand building for agency, contractor and consultant

Review of DPR
![Page 61: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/61.jpg)
Why Review of DPR
DPR generally prepared by a team not directly responsible for implementation
Many DPRs do not get implemented
Project team and its Leader must own the DPR on which project is implemented
To avoid any blame game later on
61
![Page 62: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/62.jpg)
Reviewing DPR by DMRC Corridors revised to align them to the busiest roads
Contract Packaging changed for better quality and control e.g. Metro Corridor:
Contract Package
• Two Contract MC1A & 1B.
• Design & Construct -EPC
• The Packaging is done based on proposed method of construction i.e.(cut & Cover vs Tunnel Boring)
• Civil Engg. Electrical & Mechanical, Lighting(AC & Ventilation) all combined.
DPR
• 10 Civil Structure Contracts.
• Construct Only.
• Tender Documents are prepared on the basis of traditional multi-contract implementation Strategy
• Several E&M Contracts
• Several Ventilation/AC Contracts

Why PMC ?
A new SPV is neither experienced nor adequately equipped to handle the project management on its own.
To keep organization lean
Professional Management
Bridging the Knowledge Gaps
Better Relationship with Contractor
Managing New Contract types

Key Dates vs Milestones
Both have a date specified in number of weeks from NTP for each
Key Dates are constraints for Project Network but Milestones are not
Non adherence to a Key Date invites penalty while that of a Milestone only delays the respective payment
Achievement of subsequent Key Date gets refund of penalty on earlier Key Dates while achievement of any milestone is independent of any other milestone
Key Dates were renegotiated for early commissioning while Milestones were allowed to be split for improving cash flow to contractor

Scheduling Strategy of DMRC
Chief Program Expert in GC was responsible for developing Primavera schedule
Stage wise commissioning dates identified in top level schedule
Cut off dates for all policy, technical, and contractual decisions in the planning phase
While fixing key dates for contracts, strategic buffer was kept at the end
Two level project management
– Corporate level: Key Dates for interfacing and buffer management
– Contract level: Milestones and Network Technique for monitoring

Scheduling Strategy of Contractor
Cumulative Payments ‘S’ curve matched with the Earthwork and Concrete ‘S’ curve derived from Schedule
Estimation of cost, payment flows and Programme logic followed each other
Some key resources centralized for reducing uncertainties- Lab, Batching Plant, Rebar Fabrication yard, Plant Maintenance, stone crushing plant
Objective: Latest Start and Highest economy
Proposed: 3 phase construction, for reusing temporary structural steel

87
Project Feasibility by the Contractor
It is inherent in the process that a contractor follows in responding to the request for proposal
Tender System should be designed to ensure proper feasibility study by the contractor for complex projects (EPC)
Pre Qualification and Technical Proposal plays an important role in this
![Page 88: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/88.jpg)

Request for Qualification (RFQ)
![Page 89: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/89.jpg)
89
Why need Pre Qualification?
Preparation of High Value EPC Bid: a time consuming and costly affair
Good parties do not invest in bidding unless they have a 20% chance of winning
Pre-qualified bidders provide a structured and meaningful feedback on the bid process and documents
They become stakeholders in the faster completion of the bid process
Necessary for bigger and complex projects
![Page 90: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/90.jpg)

9191
Technical Proposals Essential for Complex Tenders
Drawings speak much more than Specifications
To avoid interpretation problems later
Authority is paying for the works and shall have to maintain the assets
To bring the understandings of different bidders at a level playing field before opening financial bids
Example of Vishwavidyalaya metro station technical evaluation
![Page 92: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/92.jpg)

Evaluation of Tender Proposal
GC teams of experts in each field including programming constituted
Based on pre-bid queries and meetings with pre-qualified Tenderer's eight amendments issued
211 clarification questions covering every aspect of the proposal raised- many repeated to get clear confirmation
Answers/ confirmations sought in unambiguous terms together with revised proposals in many cases
NPV computation for the financial proposal

96
Alternatives and Options in Tender
Alternatives for deviations from Employer's Requirements and Outline Specifications in separate ‘Technical’ and ‘Financial’ packets
Options for change in basic nature of project
– Option A- Tunneling from Ch11+025m to 12+000m (Rocky area) instead of Cut & Cover
– Option B- Entire stretch with Tunneling instead of Cut & Cover
Alternatives are deviations in the Base offer itself while Options are complete set of optional tender

97
Value Addition in Tender Process
Interactions with tenderers lead to understanding of break up of offer and risks that were priced
A reduction of more than Rs. 60 crore was achieved in LS Price
– By including Utility Diversion in Provisional Sum and increasing it by Rs.15 crore
A reduction of more than Rs. 200 crore was achieved in LS price due to following changes
– Min soil cover over tunnel/station box roof relaxed from 2m to 1m at localized places like subways
– Road allowed to be raised and regraded at localized places to meet min soil cover without raising tunnel alignment

One time or a few times activities
Repetitive Activities
Temporary Organization Permanent Organization
Decisions Based on situations
Decisions Based on set rules
Higher technological and knowledge input
Mechanized or systematized set up
Managing constraints through unknown routes
Hardly any unknown situation

Project Management
It has three dimensions
– Budget, Time and Quality Standards
An efficient organic way of achieving the Project Goal with necessary tradeoffs among the three
But be careful against treating it as hard quantitative CPM/PERT application software
It is actually a Soft Behavioral and System Approach
Hierarchy of Decisions is key

115
No Duplicity of Implementing Agency
Agency developing the infrastructure is in a better position to manage civic services at site
– No dependency on DJB, DVB, MCD, MTNL for utility diversion
This avoids blame game and feelings of helplessness
Compare this with the preparation for the Commonwealth Games 2010
No amount of GOM or Committees can replace the decision making process of one sole agency

Primavera Project Plan
An important tool for developing and checking the integrity of Project Plan
But limited use for monitoring and interface at discussion level
Simple Gantt Charts were used for monitoring in addition to Primavera reports

Monitoring through Cost Center and Milestones
Cost Center bifurcation helped in distinct responsibility and monitoring of works of various disciplines in one composite contract
Every conceivable requirement in contract linked to at least one milestone with coding
– 4A.10A [Vishwa Vidyalaya Station (4A), Station Box external walls (10) 50% complete (A)]
Even Contractor’s monthly supervision (1.12 to 1.61), monthly site running (1.79 to 1.128), Quarterly Audit reports on Quality/Safety/Environment (1.62 to 1.78) had one milestone each
Every submission is linked to a milestone
The coding of milestone and the organizational structure ensures that the responsible person for each milestone is known
125
![Page 126: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/126.jpg)
Milestone is the Focal Point
Network Programme is based on Milestone
Certification of completion of Milestone by GC enable payment
GC asks Production wing why certain Milestones that should have been completed in the month were not completed
Accounts wing computes the achievable milestones to get required cash flow and chases Production for completing
126
![Page 127: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/127.jpg)
Milestone Focal Point…
GC asks Quality, Safety and Environment wings for closure of NCNs and blocks payment of respective milestones
Accounts chases theses wings for getting blocked Milestones cleared
Quality, Safety and Environment wings chases Production for compliances so that they close the NCNs to release the milestone payment
127
![Page 128: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/128.jpg)
128
Assuring Cash Flow to Contractor
Weekly cash disbursal monitored by MD
80% payment within 3 days of submission of contractor prepared bills
Recovery of Advance suspended for certain period
Advances against ‘under consideration claims’
Milestones allowed to be split for faster cash flow
Motto: No Contractor should suffer for want of cash flow
![Page 129: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/129.jpg)

Monitoring Strategy- DMRC/ GC
• Monitoring changes behavior:
– This rule used to channelize energy
• Separate measurement units for different departments of contractor- Dealt separately to keep them motivated
• Simple measurements to reflect overall progress-e.g. Volume of Earthwork, Volume of Concrete
![Page 130: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/130.jpg)

GC/ DMRC’s Hot and Cold Strategy
• Too harsh in the beginning, even at the cost of progress
• Cyclical harshness in the middle, correcting the course
• Lenient toward the end, pushing the progress and making contractor succeed
![Page 133: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/133.jpg)
133
Recovering Delays
Visible implication of a day’s delay to the SPV
Visible implication of a day’s delay to each contractor
Above should be known to every engineer and worker on the project
![Page 134: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/134.jpg)
134
Visible implication of a day’s delay
• To DMRC
– Each day that the project is delayed, the cost goes up by Rs.1.4cr. due to inflation and DMRC deprived of Rs. 89 lacs of net revenue.
– Each day saved will benefit the city to the extent of Rs. 4.5 cr. in terms of fuel saved & other social benefits.
• To MC1A Contractor
– 0.005% of contract price every day( Rs 5 lakh) if a key date is missed but refundable when subsequent key date is achieved
• Constant reminder: Project Clock ticking number of days left to commissioning
![Page 135: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/135.jpg)
135
Buffer Management in Construction Projects
• Delays are rule rather than exceptions
• As soon as a contract is signed it starts slipping
• Key to success lies in Effective Buffer (Slippage) Management:
– Keep Buffer away from the Activity In-charge
– Link Buffer with Reserve Cash
– Slippages cause loss and Acceleration costs money
– Use Buffer Management for galvanizing/ re-energizing the organization
![Page 136: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/136.jpg)

138
Tradeoff Between Quality and Time
• Initial Stringent norms were relaxed to assist the Contractor in mobilizing additional resources
• Construction methodology was allowed to be revised
• Additional smaller subcontractors and indigenous equipments were allowed
• Temporary works were allowed to be simplified on the experience gained allowing faster work with lesser material
• Non-conformances were closed with acceptable corrections
![Page 139: Management Control System- Delhi Metro_10042016](https://reader030.fdocuments.us/reader030/viewer/2022021502/58a765091a28ab217e8b67c3/html5/thumbnails/139.jpg)
139
Tradeoff Between Cost and Time
• Taking up parallel works by abandoning phasing by mobilizing additional alternative materials
