The 1.7 K.M. stretch of doubling work near Kaveri Bridge at Srirangapatna, which was pending due to the location of Tippu’s Armouryright in the way of proposed alignment of Double track, will soon be takenup and completed. With the completion of doubling of this stretch, the entire Mysuru-Bengaluru line will become double line.This is made possible as the Tippu’s Armoury, the masonary structure weighing 900 tonnes has been shifted using International expertise by about 130 metres well beyond the limit required for the 2nd Line.

A request was made to Govt. of Karnataka to arrange to shift the monument within the available Railway land.In turn Govt. of Karnataka has agreed the proposal of shifting of monument through cabinet approval and conveyed their decision that the “shifting of the monument has to be carried out by Railways with their own cost”.

Though the Govt. of Karnataka has accorded approval for shifting, the new location was required to be cleared by National Monument Authority of India as the area is a restricted area (100 to 300m from the monument).Railways sought the permission in writing for the same and the permission granted by the Competent authority o­n 14-03-2013 with a validity of 03 years from the date of issue, subsequently extension was granted for o­ne more year.

This being unique work, executed for the first time in India, no agency was readily available and the methodology for the shifting was also not known.Construction organization of South Western Railway has engaged Institution of Engineers (India) for providing consultancy services. Institution of Engineers (India) has submitted their report.In addition, Railways, also has taken the available literature from internet and interacted with the agencies in USA who are executing similar shifting/translocation works through email, Phone and o­ne of the interested working agency of construction organisation has arranged a private visit of the “Expert House Movers”,USA to the monument, interaction could be done with them.With all these inputs, methodology for shifting could be formulated.Approval of Department of Archaeology, Govt. of Karnatka was obtained for the methodology of shifting.Tender schedule also formulated based o­n the above inputs.

Tender for the work invited first time received no response.Two agencies who made JV arrangements with the agencies abroad (with experience of translocation of buildings) participated in the tender floated second time.The work was awarded to M/s. PSL Engineering (Indian based) – Wolfe (USA based) (JV).

The shiftingwas very sensitive and critical work as the same is close to existing ASI heritage monuments, running Railway line, Cauvery river, old/new Railway bridges over the river.Extensive precautions have been taken by protecting the work site with due barricading.Preparatory work for shifting has been started almost two months back.


PROTECTION TO EXISTING RAILWAY TRACK:The monument is located at 10.1m from the center line of existing Broad Gauge track, to facilitate excavation of 4m from the formation level at the edge of formation 40 nos 1m dia bored cast in situ piles are driven at 1.2m c/c parallel to the existing track.

Zones of load:The building is divided in to 03 zones as per the actual load distribution, and the requirement of jacks to be inserted underneath the structure were arrived based o­n this analysis.
Carry line of the building:As per the approved plan 2’-0” above the floor level is called as the carry line.Armoury building will be carried o­nly above this carry line, the portion underneath this carry line must be reconstructed at the new location.Armoury building is having an irregular boulder filled foundation grouted with sand.For insertion of beams the holes must be cut in the wall, the same can’t be done in the boulders hence the same is done in the main brick masonry walls underneath the carry line.
Insertion of Load frames:For lifting and moving the building above carry line, Load frames consisting of 05 nos. of Main beams, 11 nos. of Cross beams and 31 nos. of needle beams as per the approved drawing.
As per the load distribution of zones of loads there are 37 jacks to be inserted underneath the load frames.All these jacks are connected to the Unified jacking system for simultaneous and synchronized operation to prevent any unequal lifting and damages to the structure.
Lifting of the structure:After insertion of all the beams, the structure to be lifted using Unified Jacking system by 2’-0” and supported o­n wooden cribs for insertion of roll beams, rollers and Push rams.
Movement of structure:The location approved for shifting of the monument by ASI, is diagonally located from the current location.Due to the geometry of the building the building can’t be moved diagonally, the structure must be moved in two mutually perpendicular location to its final location to keep the orientation same.The move involves movement of100m length along the first direction and 30m long in the second direction.
Lowering of Structure:The building will be lowered and integrated o­n the pre-laid foundation at the new location.

First such work in India completed successfully today.

Scope of shifting Work

(I)Preparatory Work

(2 months)

§Detailed feasibility & investigative studies

§Protection to existing Railway track.

§Making foundation ready at new location

§Excavation work around the structure

(II)Actual Work

(4 days)

§Insertion of load frames

§Lifting of structure

§Movement of structure

§Lowering of structure

(III)After Shifting

(1.5 months)

§Separatingstructure from beams

§First such translocation of a structure in India – very important given the historical value of monument involved.

Extremely sensitive as the site is adjacent to existing Railway line, A SI protected monuments, Cauvery river, Railway bridges over the river etc.

Mysuru-bengaluru Doubling project

Last stretch of 1.7 Km pending for translocation of Tippus Armoury

Track linking to be completed by : 31.03.2017

Inspection of Commissioner of Railway Safety and sanction will follow

The entire doubling of 139 Km section will be completed.

Doubling was done in phases

Will help in dealing more trains and reduce running time of trains

Will be immensely helpful in connecting Bengaluru and Mysuru - two most important cities of Karnataka

Ramanagaram-Mysore doubling (93km) with electrification of Kengeri - Mysore (125 km) - Target in 2015-16 is 28 km

Cost sharing pattern : Doubling GoK : Rly – 2/3 : 1/3,

Electrification GoK:Rly – 1:1
