1 BULK EXCAVATION AND DEWATERING

1.1 Bulk Excavation

• Bulk excavation, in the order of 300,000 cum of soil (which includes a 2m working

space around the excavation footprint and a batter of 1: 1.5), has to be undertaken

within the first * months of the Construction Schedule as the initial activity. (Pile

driving will commence from the reduced level not from the commencing surface.)

Excavation and disposal of this quantum of material is a major logistics issue in its

own right and one which must attune to the LEED Principles of the development.

• Logistically the schedule will require 1,500 cum of soil to be excavated from the

buildings footprint and working areas every day for the excavation period.

Transportation of the bulk material has been assumed on a 3cum per truck basis, i.e.

100,000 truck moves out of the site are required.

• COMPANY has programmed a continuous round the clock evacuation process which

we believe will be permitted by the police and the Municipality officials for the X Area.

Should this not be the case the time frame identified will be critically constrained.

• Excavation will be undertaken in three Stages as identified on the attached Bulk

Excavation Diagram (Appendix 1). It is COMPANY’s intention to open up the

excavation area in the 3No. Stages to reduce difficulties with dewatering.

• Excavation plant will consist of 4No. Tracked excavators of 1.0 cum capacity and a

fleet of 25 to 30 dumper trucks.

• Disposal of the soil arising’s will be to low lying areas that require fill. Permission to

dump material has been provisionally obtained.

PROJECT EXECUTION PLAN (Example)

http://www.projectcontrolplus.com/



• The round trip cycle for the disposal of soil from the bulk excavation activity has been

assessed as 2 hours per truck. On this basis a single truck, operated with two drivers

over two shifts will remove 60cu m per day.

• Logistically, trucks will enter the site via the Southern Gate No.1 and leave by

Southern Gate No.2.

• It is COMPANY’s intention on completion of portions of the excavation to immediately

import soling material which will be spread over the entire area of the excavation

prior to piling to achieve a suitable piling mat. This operation will require the

importation of approximately 22,000 cum of stone cobles. This operation will require

the soling material to be delivered by rail to Kolkata from where trucks will be loaded

and the material transported to the site.

o Phase 1 Excavation Soling – 6,000 cum (2 weeks)

o Phase 2 Excavation Soling– 7,000 cum (3 weeks)

o Phase 3 Excavation Soling- 9,000 cum (4 weeks)

• Delivery of soling material will be by trucks of a capacity of 3 to 3.5 cum. We

anticipate a round trip cycle time from the station to the site and back of 2 hours,

hence each truck will deliver approximately 25cum per day over two shifts. We plan

to complete the soling operation with a fleet of 20no. Trucks per day, i.e. a production

rate of 500cum per day.

1.2 Dewatering

• The Ground Water Table at the time of test boring was recorded as being 2m below

the commencing surface. Test bores were undertaken in the month of October. It is a

known fact that during the Monsoon period (1st June through to 30th September) the

Rajarhat area is susceptible to inundation and flooding. We must assume that at the

start of the monsoon the water table will rise to effectively the commencing surface

level. (We note that the ground slab is 450 mm above the common ground level).

• COMPANY is also cognizant of the fact that heavy, but intermittent, rains can occur

between Aprils and May i.e. pre monsoon rains.




• Based on the above premise the key to the project is to achieve greatest productivity

in the 6 month period prior to the rainy season. COMPANY’s current planning is to

have the Stage 1 area partially backfilled against the permanent basement walling by

the start of rains. It is proposed that the Western alignment of the basement Stage 1

will have a 1m high block-work wall install across the works in the North – South

direction to create a barrier against water and mud ingress. A similar block-work

barrier will be installed across the N-S divide between Stage 2 and Stage 3. (The

effectiveness of the barrier will be susceptible to the extent of the basement walling

that can be installed in Stage 2 by the start of the monsoon period.)

• Dewatering of the site, i.e. to lower the natural phreatic surface of the water table is

planned on the basis on a series of 28No 10 horsepower pumps (Refer to Appendix

2) regardless of the Stage completion attained by the time the monsoon starts.

Dewatering suction pumps will be installed in slot drains which will be excavated to a

deeper level that the piling mat. Water entering the channels will be directed to the

sumps and the pumps will evacuate the water. Filtration screens will be employed to

reduce the quantum of silt which is suspended in the run-off; it is considered practical

to discharge the water directly to the adjacent canal without settlement duration.

2.0 PILING AND PILE TESTING

• COMPANY now proposes to introduce 550 mm diameter piles to both the G+15

structures and the G+4 Buildings. Pile liners of this diameter are readily available in

the market.

• COMPANY’s current estimation of the number of piles required for the entire facility

is approximately 6,000 no.

• The estimated length of the piles will be approximately 25m with a predominant

frictional resistance rather than end bearing. Piles will be driven from the -4.5m level

within the excavated area.

• Driven liner – cast in-situ piles will be constructed using sled mounted derrick rigs with drop hammers. It is estimated that a productivity level of 3No piles per day can be achieved with one of the prescribed rigs. Based on this productivity rate, the overall quantity of piles required and the schedule requirement to complete all piling there may be up to 15no. Rigs employed on the site at any one time.

• Piling will be executed in the areas of Blocks I and L as the initial works to allow the

high rise portions to progress. Piling will subsequently progress across the site from




East to West bearing in mind the time constraints imposed by the overall construction

programmer.

• Piling activities will commence with the execution of a test pile, out-with the site area

(unless the client chooses to perform such a test themselves in advance of the

works).COMPANY propose a straight forward Kent ledge test in accordance with IS

2911. This process will take a minimum of 28 days to complete due to the need for

the pile to attain 28 day strength with the approved concrete mix.

3.0 PROPOSED STAGES OF THE WORKS

• As noted above, the project execution plan requires the staging of specific works and the prioritization of the two G+15 Blocks. The summary of works stages will be as follows:-

o Block I - April ’12 to May’13

o Block H - July’12 to January ‘13

o Block L - June ’12 to May’13

o Block K - Sept’12 to April’13

o Block J - Sept’12 to April’13

o Block G - Sept’12 to April ‘13

o Block F - Nov’12 to June ‘13

o Block E - Feb’13 to April ‘13

o Block D - Feb’13 to Aug’13

o Block C - March’13 to Oct’13

o Block B - April’13 to November’13

4.0 WATERPROOFING

o Block A - April’13 to November’13

o Non Tower Areas – Sept’12 to July’13

o Utility Bld/ Auditorium/ Guest House – November’12 to September’13




4.1 Basement Waterproofing

• Waterproofing of the basement area will be achieved using the bituminous

membrane proposed in the specification and as detailed in the attached

“Construction Methodology for Waterproofing Work”. (Appendix 3)

• Waterproofing details will be documented and sketched out for inclusion in the

WMS. Primarily the horizontal membrane will be layered across the basement in

an N-S alignment following the completion of the pile heads. Pile Heads will be

wrapped in the membrane and the sides drawn up to integrate with the horizontal

layering.

• At the intersection of the horizontal membrane and the vertical wall section of the

outer basement wall the membrane will be turned up and over the perimeter of

the base slab and extended on the outer face of the basement walls follow their

in-situ casting.

• Water bars will be incorporated at the joint between the slab “kicker” and the

basements exterior walls.

• Bitumen primer will be applied in two coats prior to the membranes application.

4.2 Roof Waterproofing

• Roof areas will be waterproofed in accordance with Appendix 3.

5.0 FORMWORK AND SOFFIT SUPPORT SYSTEMS

• A detailed analysis of the project’s shuttering and formwork requirements has been

undertaken to both resource and expedite the works. The primary shutter and formwork

components are as follows (Refer to Appendix 4 for pictorial details):-

Pile Heads – Steel shutter panels (Size 0.6m x 0.4m)

Basement Floor areas - Plywood on wooden frames for edge shutters

Basement Columns – “L” form shutters (Ht 3.5m)

Basement Walls - Conventional inner and outer wall forms with vertical soldiers

Basement Ramps - Acrow prop system with Doka supports

Basement Roof Slab (Grd. Floor) – Aluminum segmental shutters




Core Shear Walls and Lift Shafts – “Jump from” formwork

Upper floors - Aluminum segmental shutters

Upper Columns - “L” form shutters

Soffit shutters are provided with a self-lifting mechanism which allows the sections to be raised to the next floor level without the need of a tower crane.

6.0 CONCRETE PRODUCTION CAPACITY AND DELIVERY

• The concrete requirement for the project has been identified in the BoQ’s as being 105,000 cum. COMPANY’s requirement is to complete the RCC works in 17 months in order to achieve the completion date of the 31st March 2014. On this basis we need to batch between 200 and 300 cum of concrete per day. COMPANY propose to erect two 30 cum batch plants on the site with a common aggregate stockpile and cement silos. Typically 30 cu m plant can consistently provide an hourly out-put of 20 cum. accordingly, a maximum hourly out-put of 40 cum is anticipated. Typically we anticipate that the plants will batch differing concrete mixes. On this basis we anticipate a delivery of 20cum per hour over a10 to 15 hr duration.

• Concrete will be delivered to the pump locations by transit mixers owned by COMPANY. We anticipate a 40min cycle for an individual transit mixer to load (10mins.) travel to the site pump (10mins.), off –load (10mins.) and travel back to the batching plant. On this basis the transit mixer will deliver approximately 10cum of concrete /hr on this basis we intend to provide a minimum of 3No transit mixers for the works during the RCC batching period.

7.0 CRANES AND HOISTS

• Crane provision for the Project has been devised based on the following primary operations:

o Hoisting of reinforcing bars

o Transfer of column shutters and Acrow props.

o Mounting and dismounting of concrete boom placers

o Concrete placement to columns and shear walls

• A 50m radius tower crane of tip capacity of 3 tones and a maximum lifting capacity of 6.5 tones will be provided adjacent to each of the G +15 Blocks. (TC 1 and TC 2) Each will be strutted from the building. Neither cranes slewing circle will interact nor both cranes are terminated at the +60m level above the ground level.

• Two 1.3 ton capacity tower cranes will be provided between Cores 1 and 4 and 4 and 6. (TC 3 and TC 4) These cranes will have an operating radius of 40m and a tip load capacity of 0.6 tones.

• In addition to these fixed tower cranes a further mobile crane of 1.0 ton tip capacity will be operated along the road way between the Utility block and Building A. This crane will traverse between the Auditorium and Core 2 i.e. covering the area not reached by TC 3 and TC 4.




• In order to lift general building materials, fitments, furniture, MEP materials etc., COMPANY will employ 10No. Hoists which will run from the ground level and will climb with the buildings. The G+15 structures will be provided with man hoists to speed the workers accent.

8.0 CONCRETE PLACEMENT METHODOLOGY

• Concrete placement is constrained by a number of practicalities, namely;-

o The common basement roof prevents the use of a mobile boom placer from entering certain areas. Boom placers can be used along the perimeter road areas and at the Eastern and Western ends of the Blocks.

o The design of the buildings is elongated rather than square and vertical requiring a longer reach for a boom placer. The establishment of climbing boom placers for G=4 levels is not warranted.

o Crane utilization must be optimized for the transfer of rebar and materials and not for concreting by means of skips. (Which is a time consuming process)? Certain columns and areas must, however, be concreted by means of skips.

• We have identified the specific means for concrete placement, namely:-

G+15 Blocks I and L - Climbing Boom Placer

Cores 1/2/3/5/6/&7 - Mobile Placer Boom (37m reach)

Blocks A/B/C/D/E - Mobile Placer Boom (37m reach)

Blocks H / F - Ditto

Blocks J / K - Ditto

Core 4 - by skip from either TC 3 or 4

Block G - partially by skip (TC 2 or 4) and the

Balanceby “Head Load”

• The mobile boom placer will move around the perimeter of the basement, not actually on it.

• COMPANY’s current concreting schedule indicates a concrete placement requirement of the order of 200 to 300 cum per day. (105,000 cum in 17 months). Placement by boom will be running at approximately 150 to 200 cum per day. With an anticipated concrete batch capacity of 30 cum per hour, 1no. Mobile boom placer will suffice to undertake the works in parallel to the fixed boom placers for the two towers.

9.0 SUB STRUCTURE WORKS

• Sub structure works comprise:-

o Pile head preparation and casting

o Elevator pit casting

o PCC laying and leveling




o Waterproofing installation

o Basement floor casting

o Column and perimeter basement wall casting to soffit of ground floor slab.

o Vehicle access ramp casting

o Core casting

o Staircase casting

o Ground floor beam and slab casting

• COMPANY have programmed their works to proceed with the two G +15 Blocks first followed by each of the G+4 Blocks

10.0 SUPERSTRUCTURE WORKS

10.1 G+4 Blocks

• The primary concept for casting the superstructure works to the G+4 blocks is to combine the core pour (Of approximately 70cum) with a section of the upper floor slab and beams which are integral to the slab. A floor slab area of approximately 30m x 25m will be poured along with the core, i.e. approximately 250 cum of concrete will be required for each of these pours. An average pour of this nature will take approximately 10 hours to complete.

• Intermediate floor slab areas, i.e. between the cores, will be poured in one go and will again be of the order of 250 cum of concrete per pour.

• Floor leveling during casting will be achieved using tamping rails and a tamper of length 5m. Tamping will be done across the building (N-S) in strips of 5m. Flooring levels will be controlled by lasers set up on each floor

11.0 FAÇADE INSTALLATION

• Façade installation will commence with Building H in January 2013 and complete with Building A in December 2013.

• Installation of façade panels will be from suspended gondolas.

• For the G+4 buildings, sections of façade will be raised in one lift, for the G+15 buildings the lifts will be in 3no. 5 floor sections.

12.0 MEP INSTALLATION

• MEP installations will commence, under the direction of COMPANY / Sterling and Wilson, with the installation of the basement drainage system, sewage collection pipework and sump pumps. This will be followed by the installation of the basement sprinkler system and the down take pipework for the core areas (sewers and fire risers). As the buildings floor construction proceeds up MEP installations will follow with a two floor buffer.

• Chilled water pipes will be installed through-out the basement




13.0 CO-ORDINATION WITH NOMINATED SUB-CONTRACTORS

• The co-ordination of activities to be undertaken by the client’s Nominated Sub-contractors requires a clear delineation of the entry times and work durations prior toarea handover to the next follow on package contractor. In order to achieve the programme of 26.5 months the NSC’s cannot enter specific areas until COMPANY are through with their works and the area is secure from the ingress of curing water or rains (I,e façade completion for the area is a pre-requisite in most instances).

• COMPANY will, therefore identified the key entry dates of NSC’s on their detailed construction schedule and will monitor their own works to determine if the projected entry date is indeed practical and an area can be handed over. On hand over the status of the works area will be recorded and photos taken. On completion of the NSC’s works the process will be completed and the area again handed to the next NSC.

14.0 INTERIOR FIT-OUT

Interior fit-out can be itemized as follows:

14.1 Stage 1 Activities

• Interior block-work, plastering and painting of partitions.

• Installation of raised flooring

• Installation of glazed or metal partitions and screens

• Installation of Second fixes carpentry works including fire doors, interior entrance doors, office doors etc.

• Installation of door ironmongery, locks and key provision

• False ceiling installation and light fixture insertion/connection

• Installation of ac diffusers and grilles

• Installation of hard flooring (Including electrical and IT cable raceways)

14.2 Stage 2 Activities

• Installation of carpeting

• Installation of desks and divider panels

• Wiring of IT and Telecom backbone and patch panels

• Audio and visual systems

• Installation of blinds and screens

• Delivery and placement of moveable furniture and electrical goods to kitchens

• Stage 1 Interior Works, as itemized above, will commence from 1st February 2013 in Block H and will conclude by 31st January 2014.




• Stage 2 Interior Works will commence from 1st November 2013 and conclude by 05th March 2014.

• Note: It is COMPANY’s assumption that the Client will commence the installation of PC’s, servers and high value equipment only after hand over of the building on

15th March 2014. Insurance cover under the COMPANY CAR Policy would not include equipment to be supplied by the Client.

15.0 PROVISION OF POWER, WATER AND WILD AIR

• As noted above (Section 3.0) power for testing and commissioning is to be provided by CESC to ensure a constant, non-fluctuating supply is available. To obtain the permanent power supply, COMPANY will need to cancel their temporary power supply and reestablish the power supply in the name of TCS.

• Testing and Commissioning is scheduled to commence on 1st February 2014; a six week duration has been allocated.

• Water for flushing the chilled water supply lines and commencing the operation of the chillers must be available from 1st February 2014. COMPANY will need to apply for the permanent water supply in the name of TCS and operate as noted above in respect to bill payment. (COMPANYare aware that permanent mains water supplies cannot be assumed in the development area by 2014). The use and number of bore-wells required for water provision post the construction period is entirely dependent on the yield attainable throughout the year. During rainy seasons water will be in abundance but in the drier months the individual yield will drop considerably. Yield data will be available from the 3No. Construction bore-wells.

• Wild air from the AHU’s is to be available from 05th February 2014.

16.0 TESTING AND COMMISSIONING

• We have assessed a period of 1.5 months for testing and commissioning of the overall complex commencing from 1st February 2014. As noted in Section, MEP installations will commence from February 2013. As each system is installed our MEP contractor Sterling and Wilson will check the continuity of the system in the individual block or building. As of the 1st February 2014 we programme to have mains power available, mains water on tap and both the chiller units and the back-up DG’s in place. The Testing and Commissioning programme will then comprise:

16.1 Electrical (Mains)

o Earthing and electrical continuity checks

o Circuit isolation checks

17.0 INFRASTRUCTURE

• Permanent road and parking bay construction will commence as soon as the buildings are backfilled. COMPANY intend to utilize the sub-base and base course materials as running paths for construction equipment. The current programme of construction should allow road box cutting and sub base / base course laying to start in October 2012 and carry on through to the first week of March 2014.

• A total of approximately 2,000 running metres of PCC kerbing are required to be manufactured. Kerbing will be installed from 1st October 2013; asphaltic road layers will be placed from 1st January 2014 through to 5th March 2014. Surface water gully pots and collector pipe-work will be installed in parallel to the kerbing operations.

• Construction of the main ground level car-parking area to the North West side of the plot cannot start until the concreting works have been concluded and the batching plants disassembled. Disassembly takes 28 days. Concreting completion to buildings is scheduled for 1st November 2013 at which time one batching plant will be removed. The second batching plant will be required for pipe duct bank encasement and backing to curbstones. The second batch plant will, therefore, be decommissioned between 1st February and 18th February 2014 by which time the curbstones for the car park will have been installed. Layer works and asphalting will then be completed in the second week of March 2014.

18.0 LANDSCAPING

• Landscaping around the main buildings, the Guest House, the utility block and the entrance gates will be undertaken between the 1st January 2014 and 15th March 2014. However, there is a need to retain offices for the Client’s Representatives, COMPANY and Sterling and Wilson plus offices and stores for NSC for a period of approximately two months after the buildings have been handed over during which time COMPANY staff will be on hand to assist and train the COMPANY Facilities Management Team. The Temporary Working Area to the North West of the site will therefore only be cleared and landscaped between 1st May and 1st June 2014.

• Top soil for the landscaping will be retained separately from backfill material but stored in the same location (Lay Out Plan of the Site). Approximately 10,000 cum of topsoil will be available for spreading and ground make up. Top soiling will start in November 2013 with




the areas adjacent to the boundary wall and then move to the inner lines along the buildings.

• Planting requirements will necessitate the provision of a site nursery and propagation area. (Which will be located where the backfill stock pile is initially located) COMPANY intend to accumulate the required plants, shrubs and trees over period of 6 months, commencing 1st July 2013. Planting will start after soil deposition and drip feed irrigation pipe-work installation. (Compliant with WHO requirements for the use of treated sewage as irrigation water). As noted above, planting of the perimeter areas will commence in November 2013 and on the inner areas around buildings from mid-January 2014.

• Sports facilities (basketball court and tennis courts) will be installed from 1st January 2013 and completed within one month.

• Tending of planting by COMPANY’s site team will cease on the 7th March 2014 when the facility will be handed over to the permanent COMPANY FM Team who will provide all necessary gardeners to maintain the landscaped areas.

19.0 PROJECT HAND-OVER

• With regard to the Tender Documentation and due to the extremely restricted timescale, the Contractual responsibilities linked to the CAR Insurance Policy and the need for COMPANY, on behalf of the Client, to obtain an Occupation Certificate commencing from the 15th March 2014, Client entry into the building complex prior to this date has not been considered.

• Should the Client consider an early Beneficial Occupancy of areas of the complex before the 14th March 2014 date COMPANYare agreeable to attempt to plan their construction activities to accord to the Clients wishes. However, COMPANY are aware of the issues of affecting a partial hand-over:

• The critical need to sustain a stable power supply to the complex. (i.e. early provision of mains power)

o The fact that the complexes servers are located in Block A but the major work station areas are in Blocks B and C together with Administration.

o The canteen facilities are located in Block A i.e. away from Blocks B and C (No individual Block appears suitable as a stand-alone facility which could be prioritized).

o The need for the Utilities Block to be up and running at an earlier date than currently planned.

o Segregation and the safety of employees while working within a construction site.

o Surface water removal, sewage collection and sewage treatment for a partially completed complex

o Provision of an Occupation Certificate for a partially completed project.




• A suitable working environment for TCS employees would only be provided if the initial facilities can act as a self-contained complex.

• The actual functional hand over of the IT Complex will only take place after 48 months of project completion during which time COMPANY will operate the facilities on behalf of the Client. For a complex of the size of the TCS IT Park COMPANY will require a full Facilities Management Team to be in place as of the 1st March 2014.

• COMPANY will have available a team of 10No FM technicians for training and hands on instruction in the buildings systems and operational requirements from the 1st March date. COMPANY and Sterling and Wilson personnel responsible for the MEP installations will remain with the designated FM Team for a period of one month after which the new COMPANY FM team will be in charge of the facility

• COMPANY have assumed a period of one month of pedagogical and hands on training of the new FM team. The training will cover:

o Operation of all plant and equipment installed

o Use of the Building Management System and reprogramming

o Simulated Fire Alarm and response procedures

o Use of Building Maintenance Gondolas

o Scheduled preventative maintenance

o Trouble shooting and fault finding

o Spare parts and equipment inventory

o Monsoon precautions

o Security procedures and use of security equipment

o Training of this nature can be extended to the client’s team at the end of the 4 year period of maintenance should this be of interest.

20.0 PROVISION OF AS BUILT DRAWINGS AND OPERATION AND MAINTENANCE DOCUMENTATION

• A fully coordinated and cross referenced Operations and Maintenance Manual set will be provided to the FM Team. This suite of documents will address, in sectional order, the workings and operational requirements of all the component parts of the Complex. (Not just a compilation of catalogues). The suite of documents will be provided in both hard and soft copies to allow fast search capability to find the requisite text referring to a particular problem being faced.

• As build drawings will be provided as CAD drawings for loading onto the FM teams PC’s

• Assistance in the provision of an Asset Register will be provided by COMPANY staff; it is assumed that the TCS FM Team will take the lead in the preparation of the Asset Register in line with TCS’s norms and Procedures.
