C-3 Madhavaram to SIPCOT

C-4 Lighthouse to Poonamallee Bypass

City level transportation demand is catered predominantly by Metropolitan Transport

Corporation buses (MTC), Intermediate Public Transport System (IPT) in the form of shared

services along major arterials and Commuter Rail System including elevated MRTS.

The MTC operates 830 routes with a fleet of about 3,720 buses in 2018. The MTC covers

most of the CMA and even covers up to 50 km to places beyond CMA limit and carried over

50 lakh daily passengers.

The travel demand model was made available to RITES by CMRL. Same basic set of

assumptions including traffic zone system have been used for the demand forecasting for

present study. The revision in Chennai Phase II metro network / stations in existing model

have been carried out for horizon years.

The intensity of traffic at intersections along phase II corrdors is presented in

Table 2-4. It can be seen that Ramavaram Signal intersection handles the maximum

daily traffic at 175,412 vehicles (143,805 PCUs) while the lowest daily traffic is

observed at Kanmal Nagar Jn. (Nr. Madhavaram EOC Hospital) with 23,596 vehicles

(20,170 PCUs).

Madhavaram Milk Colony Metro Station (North side terminal station)

The North side station on the Metro corridor is Madhavaam Milk Colony Metro

Station. The station is proposed underground and rail level has been kept -

15.00 m (minimum) below the ground level. Proposed metro station is a

common station for Corridor 3 & 5.

Depot connections have been planned through this station for corridor 3. Two

nos. underground stabling lines on both corridors are proposed to

accommodate total eight rakes including at stabling at platforms.

ii. SIPCOT 2 Metro Station (South side Terminal Station)

South side Terminal of the corridor will be SIPCOT 2 Metro Station. The station

is proposed elevated and rail level has been kept 14.00 m (minimum) above

the ground level. It will serve the nearby private commercial areas of SIPCOT.

Reversal/stabling facility has also been planned beyond this Metro station. The

entry to minor depot in southern SIPCOT land (6.3 Ha

The aligment after passing below MRTS lines at Thiruvanmiyur station,
comes on centre of Old Mahabalipuram Road (OMR). The corridor is
integrated with MRTS by proposing a UG metro station, namely, Tidel Park
parallel to Thiruvanmiyur MRTS station.
• The alignment then, runs along OMR. The switch over ramp is proposed on
the centre line of existing road, between the underground station at
Tharamani Link road junction and elevated station as Nehru Nagar near
Kandhan Chavadi Bus stop, i.e. from Chainage 26,124 m to 26,543 m with
RL rising from (-)8.0 m to (+)7.5 m. The existing ROW at this location varies
from 37m to 32m. The width of proposed 419m long ramp shall be 12m –
13m. Hence, road shall be widened to accommodate the proposed ramp
within the ROW.

Recommendation
The Design and Build Contractor may choose any type of super structure keeping in
view site conditions, availability of construction time and other resources i.e. road
cranes/launching girders/shuttering etc. Combination of above type of superstructure
may also be chosen. Appropriate special spans may be provided for specific locations.

it will be more appropriate to enter into an EPC contract for construction in which case the
construction risk excluding financing risk is transferred to the private entity.

A contractor selection criteria checklist should include factors such as experience, expertise, certifications, compliance with regulations, and the ability to manage risks.

• Company Experience

  previous work
  years in business
  geographic territory
  previous customers

• Company Organization

  structure
  management processes
  operational procedures
  hiring and training programs
  turnover

• Quality
• Safety
• Senior Management

  experience
  tenure with firm
  division of responsibilities

• Current Projects/Backlog

  number, size, and location of projects
  percent of capacity being utilized
  status and expected completion

• Financial Strength

It is important to consider how to collect the data necessary to perform contractor evaluations. If yes/no-answer questionnaires are used, contractors will be tempted to answer in a way that puts them in the best light. For instance, one commonly used questionnaire asks contractors if safety is a priority in their business. A review of several hundred responses to this question revealed that not a single contractor answered "No," while actual work performance indicated that for many, "No" would have been the more accurate response. Thus, this type of question is of no value.

The key to a successful methodology is to develop an objective form, from which a database can be built that allows for fair comparisons of contractors. The form should be easy to use. Anyone on the bid evaluation team should be able to conduct the assessment and compare the results.

Obviously, owners must carefully analyze the data submitted by contractors. It is not prudent to ask the contractor to provide answers about the viability and completeness of its program and then simply rely on those answers when drawing conclusions about the effectiveness of its efforts. Objective information needs to be obtained and, more importantly, mechanisms for verifying the accuracy of the data need to be developed before any conclusions can be drawn.

A success reference must also be established to have some objective point against which the contractors' performance can be evaluated and compared. This normally is a scoring form used to judge the responses of the contractors being considered.

If contractor evaluation consists of simplistic questionnaires, without verification, constituting the sole basis for making judgments about contractor capabilities, little is gained at great expense. This process only creates the illusion of a fair and objective evaluation at an unnecessarily high cost, since all the effort of asking, answering, and reviewing the questions is merely an exercise in futility.

• Unified project recommendations.
• Collaborative problem solving.
• No blame-shifting between designer and contractor.
• One point of responsibility.
• Savings in time and money.

Design and Build procurement works on the basis that the main contractor is responsible for undertaking both the design and construction work on a project, for an agreed lump-sum price.

Components often included in a design-build contract include insurance requirements, payment terms, expectations of the contractor, and project requirements.

Design-build is a method of project delivery in which one entity - the design-build team - works under a single contract with the project owner to provide design and construction services. One entity, one contract, one unified flow of work from initial concept through completion.

These Conditions of Contract for EPC/Turnkey Projects are not suitable for use in the following circumstances:

– If there is insufficient time or information for tenderers to scrutinise and check the Employer’s Requirements or for them to carry out their designs, risk assessment studies and estimating;

– If construction will involve substantial work underground or work in other areas which tenderers cannot inspect, unless special provisions are provided to account for unforeseen conditions or

– If the Employer intends to supervise closely or control the Contractor’s work, or to review most of the construction drawings.

This Second Edition of the FIDIC Silver Book maintains the principles of risk sharing established in the 1999 edition, while seeking to build on the substantial experience gained from its use over the past 18 years. For example, this edition provides:

1) greater detail and clarity on the requirements for notices and other communications;

2) provisions to address Employers’ and Contractors’ claims treated equally and separated from disputes;

3) mechanisms for dispute avoidance and

4) detailed provisions for quality management, and verification of Contractor’s contractual compliance.

These Conditions of Contract for EPC/Turnkey Projects include conditions, which are likely to apply to the majority of such contracts. Essential items of information which are particular to each individual contract are to be included in the Particular Conditions Part A – Contract Data.

In addition it is recognised that many Employers, especially governmental agencies, may require special conditions of contract, or particular procedures, which differ from those included in the General Conditions. These should be included in Part B – Special Provisions.

It should be noted, that the General Conditions and the Particular Conditions (Part A – Contract Data and Part B – Special Provisions) are all part of the Conditions of Contract.

To assist Employers in preparing tender documents and in drafting Particular Conditions of Contract for specific contracts, this publication includes Notes on the Preparation of Tender Documents and Notes on the Preparation of Special Provisions, which provide important advice to drafters of contract documents, in particular the Employer’s Requirements and Special Provisions. In drafting Special Provisions, if clauses in the General Conditions are to be replaced or supplemented and before incorporating any example wording, Employers are urged to seek legal and engineering advice in an effort to avoid ambiguity and to ensure completeness and consistency with the other provisions of the contract.

This publication begins with a series of comprehensive flow charts which typically show, in visual form, the sequences of activities which characterise the FIDIC EPC/Turnkey form of contract. The charts are illustrative, however, and must not be taken into consideration in the interpretation of the Conditions of Contract.

This publication also includes a number of sample forms to help both Parties to develop a common understanding of what is required by third parties such as providers of securities and guarantees.

Drafters of contract documents are reminded that the General Conditions of all FIDIC contracts are protected by copyright and trademark and may not be changed without specific written consent, usually in the form of a licence to amend, from FIDIC. If drafters wish to amend the provisions found in the General Conditions, the place for doing this is in the Particular Conditions Part B – Special Provisions, as mentioned above, and not by making changes in the General Conditions as published.
