1 Bidders’ conference IT-4123 Supply, Replacement and Repair of Crane Rails Technical Specification Handling Engineering Group

2 Scope of the supply Supply and installation of rails in new and existing buildings Consolidation works: o Replacement of rails and/or components o Realignment o Repair Survey and inspections 01/09/2015IT-4123 Technical Specification

3 Type of contract Overcome the difficulties to establish a fixed planning Blanket purchase contract with no commitment for CERN Duration: 5 years Based on a list of reference prices (Price list IT-4123_UPL): o To obtain an adjudication price o To be used afterwards to define the value of any release order 01/09/2015IT-4123 Technical Specification

4 Price list (1/6) Definition of “sample” cases to cover CERN’s inventory 01/09/2015IT-4123 Technical Specification Rail typeFlat bar 50x30DIN 536-1 rail (A45 to A120) Support structureSteelSteel or concrete beam FasteningWeldedClips bolted on welded base Elastomer padNoYes Straight / curvedStraight Type of junction45° cut Railway length50 m Installation height8 to 15 m Refers to building length!

5 Price list (2/6) Definition of the possible interventions that may be carried out on each representative rail 01/09/2015IT-4123 Technical Specification Category of intervention Reference section of technical specification 1Supply of new rails§ 2.4.1 2Rails realignment§ 2.4.2 3Clips replacement§ 2.4.3 4Elastomer replacement§ 2.4.4 5Rails dismantling§ 2.4.5 6Survey§ 2.4.6 7Non-destructive tests§ 2.4.7

6 Price list (3/6) First part of price list is obtained by combining representative rails with interventions 01/09/2015IT-4123 Technical Specification

7 Price list (4/6) Second part of price list is used to cover variations from “sample” cases (ex. technical requirements) 01/09/2015IT-4123 Technical Specification Additional featureDescription 1Length increaseIncrease from 50 m to 62 m 2Length decreaseDecrease from 50 m to 38 m 3Curved rails Supply of rails curved over a radius of 150 m (DIN 536 rail – A65); concrete support, 50 m long 4 Aluminothermic welding See § 2.2.5.1 of Technical Annex

8 Price list (5/6) Second part of price list is used to cover variations from “sample” cases (ex. installation conditions) 01/09/2015IT-4123 Technical Specification ItemDescription 1 Team of two technicians Intervention of a team of two technicians on the CERN site for small repair works (welding of reinforcements, concrete repair). Inclusive of all costs such as, but not limited to, travel and subsistence costs 2Engineer Intervention of an engineer on the CERN site inclusive of all costs such as, but not limited to, travel and subsistence costs 3 Work planning for radiation areas Preparation work for installations in radiation areas with increased exposure risks (meetings attendance, documentation). See § 4.5.8 of technical specification 4 Rental of a scissor platform Scissor platform with a lifting height of 10 m for two operators, transfer included

9 Price list (6/6) Second part of price list is used to cover variations from “sample” cases 01/09/2015IT-4123 Technical Specification

10 Interventions(1/3) 01/09/2015IT-4123 Technical Specification FINAL SURVEY NOT INCLUDED!

11 Interventions(2/3) 01/09/2015IT-4123 Technical Specification

12 Interventions(3/3) 01/09/2015IT-4123 Technical Specification

13 Ordering procedure(1/2) For any project, contractor will be requested to provide an offer after a visit on site Price shall be calculated, whenever possible, combining items of the price list example:supply of 74m of A-65 rail over steel, straight rail, aluminothermic welding: Price: [1_2_C ]+ 2*[5_2_C] + 12*[5_6] 01/09/2015IT-4123 Technical Specification

14 Ordering procedure(2/2) In case of deviation from the sample cases, price list will be anyhow used as a basis for negotiation No commitment to order Items will be ordered by the means of release orders 01/09/2015IT-4123 Technical Specification

15 Performance of the contract 01/09/2015IT-4123 Technical Specification Category of intervention Submission of design file Start of works at CERN Completion of works 1Supply of new rails2 weeks8 weeks10 weeks 2Rails realignment2 weeks4 weeks6 weeks 3Clips replacement2 weeks6 weeks8 weeks 4Elastomer replacement2 weeks6 weeks8 weeks 5Rails dismantling2 weeks4 weeks5 weeks 6Survey-2 weeks3 weeks 7Non-destructive tests-2 weeks3 weeks
