Challenge

Project 1

1. PREPARE THE PROJECT DETAILS OF PROPOSED METRO PROJECTS IN YOUR CITY

1A. 2 MOST POSSIBLE POSSIBLE ROUTES, WHY

  • LINE-1, LB NAGAR - FALAKNAMA - SHAMSHABAD AIRPORT -(28KM)- 8 STATIONS.
  • LINE-2, RAIDURG - GACHIBOWLI - SHAMSHABAD AIRPORT -(32KM) - 10 STATIONS.

Metro Project is an extension of the existing Metro Rail network, designed to connect more city areas with an efficient and sustainable mode of transportation.

The Phase 2 project will add another 63 km of the metro rail network. The proposed lines will cover various areas of the city, including Gachibowli, the airport, and other major residential and commercial areas. The project will also include an interchange station at Raidurg, connecting to the Outer Ring Road, which is expected to improve connectivity to other parts of the city.

1B. INTERSECTION LOCATION, WHY

  • The intersection line for the hyderabad metro line project is Ameerpet and MG bus station.

The intersection lines are

RAIDURG - AMEERPET - NAGOLE.

MIYAPUR - AMEERPET - LB NAGAR.

1D. REQUIREMENTS OF TUNNEL ROUTE, WHY, IF YES WHAT SHOULD BE THE LENGTH.

Considering of the project the requirement of underground tunnel is around 1.7km near airport at a grade level to connect the passage with out any intermediates.

  • optimise the efficiency and reliability of operations and improve customer experience by moving towards a metro-style rail system.
  • support the long-term plan and vision to develop and operate metro rail network.
  • Improve access and reduce congestion of the tram system in the CBD and the road network in the north, west and south east by diverting travel to the metropolitan rail network.
  • Improve accessibility to jobs, education and other social and economic opportunities by enabling growth and more effective use of land.
  • Deliver strong productivity, sustainability and liveability benefits by providing a value for money transport solution.
  • Contribute to a safe and accessible metropolitan rail network that supports all the safety.

1E. TOTAL LENGTH AND NUMBER OF STATIONS.

  • LINE-1, LB NAGAR - FALAKNAMA - SHAMSHABAD AIRPORT -(28KM)- 8 STATIONS.
  • LINE-2, RAIDURG - GACHIBOWLI - SHAMSHABAD AIRPORT -(32KM) - 10 STATIONS.

It covers most of the places with the intermediate stations through the travel and it has intersection points to contribute to easy travel with a less construction carriage way.

2. OWNER WANTS TO AWARD CONTRACT FOR STATIONS WORK OF ROUTE-1.

2A. WHAT SHALL BE THE CONSIDERATION FOR DESIGN AND CONSTRUCTION

  • Design and construction of metro-rail has no more remained a simple straight-forward task due to various problems involved in it, like – availability of land, coordination between various disciplines.
    (like Architect, structural designer, contractors, equipment suppliers, regulating authorities, common people etc.), construction permissions, environmental clearances, project funding, timely payment to
    agencies, availability of right construction machines and techniques, fouling utilities (chartered and
    unchartered), fouling buildings/infrastructures, road diversions, safety-lapses, unavailability of skilled
    man-power etc. The delays are further associated with cost over-runs, arbitration, litigations etc.
  • AVAILABILITY OF LAND:
In many metro projects at many stretches the alignment crosses from crowed areas like markets, prime areas/villas (where high profile people like actors/politicians/sportsmen stay), temples or private
properties. In such cases the land has to be acquired areas by the client through official correspondences and legal procedures and then has to be handed over to the contractors. This acquiring and handing over takes a long time.
  • CO-ORDINATION BETWEEN VARIOUS DISCIPLINES:

In metro projects (especially underground metros) there are several disciplines involved like – Architect,Mechanical - Electrical - Plumbing engineers,Structural engineer, Geotechnical engineer, execution (construction) engineer, quality control (QAQC), safety, surveyor, vendors / material suppliers different statutory bodies, GC/PMC from client side etc. the degree of success of project depends on the effective coordination between all these parties to deliver the end product in time and specified quality without increase in the cost.

  • Construction Permissions, Environmental Clearances, Road Traffic diversions:
In big cities like Delhi, Mumbai, Chennai, Kolkata etc. the contractors are not permitted to construct or carry construction vehicles in busy traffic hours to facilitate public comfort. This imposes additional
target on the construction equipment like trailers, cranes, workers etc. While working in limited time
(mostly late nights) still keeping the same construction progress is difficult for inexperienced contractors; and without disturbing the adjoining residential areas (by sound) is a challenging job.
  • Project Funding and Timely Payment to Agencies:
Any mega project has two sides – first is ‘Technical viability’ and second is ‘Commercial affordability’. Many projects are sanctioned and funded with the help of international funding organisations. But as the time elapses the cost of the project keeps increasing rapidly.
  • Availability of Right Construction Materials and Workers:
In underground metro construction projects, selection of correct machine for specialised operations
like – rigs and hydromills for diaphragm walls, TBM for tunnels, and many other such mega equipment, plays a vital role. Apart from the equipment the construction method viz. Top-Down or Bottom-up or simply cut and cover or a box pushing technique (for a subway) decides the project speed and cost.
  • Fouling Utilities:

The fouling utilities is a major problem during consideration of metro projects during excations of a certain location it is seen with a place of electriacal and mechanical equipments and it is to be sorted out with seperate team with the clients and is to be done with the consideration of the project date and time with necessity.

  • Selection of the Contractor and Consultant:
There are so many aspects which affect/influence the urban infrastructure projects; one of them is availability of design software programs. There are many professional design software programs available in market but every consultant may have their own choice. Often the clients demand for a separate license of these software for their record / use on the project.
The following are the consideration for process of design
  • Concept design
  • Design specifications
  • Design methodologies
  • Types of structures
  • Deliverables

The following are the consideration for process of construction

  • Execution
  • Planning and monitoring
  • Project control
  • Material management
  • Quality management
  • Health & safety management
  • Vendor billing & Running account(RA- bill)
2B. WHICH TYPE OF FIDIC CONTRACT FORM TO BE FORMED AND WHY.
  • FIDIC is well known for its work in defining the conditions of contracts for the construction of industry in world-wide.
  • There are six books generally used in FIDIC contracts.
  • Here, the contractor is awarded station work for one route and it may be lumpsum contract

As, per the conditions of the contract the contract can be formed as a RED BOOK

  • The DDC shall deploy one BIM expert in addition to the team specified in organization structure and who shall be housed in either HMRA.

5C. DEFINE IMPORTANT CLAUSES OF DESIGN CONTRACT BASED ON FIDIC SILVER BOOK.

  • In the same way that unforeseen ground conditions may impact the certainty as to outturn of the contract price and time for completion, the issue of design liability can play a major role in determining the extent to which the turnkey solution is deliverable.
  • Turnkey arrangements necessarily suggest that the contractor is required to take full responsibility for the entirety of the design of the works. This will often be a point of contention, particularly where initial
    design work has been undertaken on behalf of the owner, with such designs being provided to the contractor during the tender stage with the requirement that it is to take on full responsibility for such design.
  • Numerous disputes arise in practice where there are changes in the design of the works following award of the contract. Such variations in design will be argued to give rise to relief for the contractor in terms of time and money entitlement.
  • The counter-argument to this (in the case of changes in design) is to characterise the change as simply design development, which does not serve to increase the contractor’s entitlement to time or money. It may be instructive to consider the treatment under clause 5.1 of the FIDIC Silver Book.
  • which addresses general design obligations:
  • The Contractor shall be deemed to have scrutinised, prior to the Base Date, the Employer’s Requirements (including design criteria and calculations, if any). The Contractor shall be responsible for the design of the Works and for the accuracy for such Employer’s Requirements (including design criteria and calculations), except as stated below:
  • Having established this deemed universe where the contractor has scrutinised the owner’s designs the FIDIC Silver Book pushes home the point further, going on:
  • The Employer shall not be responsible for any error, inaccuracy or omission of any kind in the Employer’s Requirements as originally included in the Contract and shall not be deemed to have given any representation of accuracy or completeness of any data or information, except as stated below.
  • Any data or information received by the Contractor, from the Employer or otherwise, shall not relieve the Contractor from his responsibility for the design and execution of the Works.
  • The rest of the same clause then goes on to carve out from the matters for which the contractor is responsible a number of matters for which the owner retains responsibility but the list is very limited in scope.
  • Hence the approach of the FIDIC Silver Book is for the EPC/turnkey contractor to create a single design liability wrap around the project, with the contractor being responsible both for the integration of the design and the construction of the works.
  • Conversely, there may be other provisions in the contract, such as notes on drawings or process diagrams forming part of the employer’s requirements, that indicate that the design has not yet been fixed and remains to be confirmed, say by the equipment vendors.
  • Owners may seek to tighten up and improve on such provisions by using devices seen elsewhere in the FIDIC Silver Book (as well as in the ICE forms), namely further deeming provisions. Thus, clauses that deal with the sufficiency of the contract price and all of the risks, contingencies and other factors that the contract is deemed to make allowance.

5D. DEFINE DELIVERABLES EXPECTED FROM THE DDC.

  • Design basis documents:

The document includes the data regarding the assumption or consideration of design.

It documents the major design criteria and recommendation for design & project details are as followed in the design.

The document also consists of geological information for consideration of design and the document also constrains if any design purposes.

  • Design caluculations:

This document includes the project information and different structural information and loading criteria, materials with standards as follows.

It has details of the construction materials, properties, design caluculations which are approved and verified.

  • Material specification:

Material specification are issued to enable the procurement & all structural and architectural materials with consumables are provided.

Specification include the type of material,sizes,shape and properties to ensure the construction as required.

  • Drawings & 3Dmodels:

The most important deliverable of engineering is drawings which is primary requirement for site to work.

The IFC drawings are used for construction. Generally 3D models are also used for quantity estimate and clash deduction can be carried with ease.

2D drawings can be extracted from 3D models to reduce the effects of drafting by directly updating in 3D model.
