1. Basics for Bunker Installation Schedule Bunker CDR 2.0
Sofie Ossowski
NSS Project Coordinator
October 2018

2. Bunker schedule integration
The Bunker is highly integrated with other ESS sub-project
CF/SEC -> D01, D02, D03 buildings
TD -> monolith area (Inserts, Light Shutters etc)…
ICS -> PSS system & timing systems
ESS schedule re-baselined
in April/May 2018
This presentation will focus on:
Access dates from CF/SEC
Joint schedule of NSS & TD in the monolith/Bunker area
Bunker construction accordingly

3. ESS rebaseline April/May 2018 Delays from SEC/CF in various areas & in NSS key Milestones
Delays compared to Baseline
Access to NSS buildings
from months
Beam on Target (BOT)
= 21 months
Beam on 1st Instrument
= 17 months
8 Instruments in User Program = 16 months
NSS project completion < 12 months

First 4 instruments delivery of cave and contents is close to critical path (Q4 2019)

9. Key Schedule dependencies & assumptions – Bunker & TD/CF interface
CF & Target dependencies from agreed dates with CF/SEC (on 12th April)
Majority of work in instrument hall (Bunker and instruments) will be done before Full Access, with reduced (80%) efficiency, but without increase in timeline b/c this is on critical path for SOUP (planning extra funds for mitigation)
High degree of parallel work with Skanska & TD – shifts will most likely be needed between projects, and high degree of safety coordination will be required.
NSS to work through summer holidays for anything on the critical path (i.e. bunker installation + installation and commissioning of early instruments)
otherwise assume normal working hours and standard ESS calendar
Wait for weather tight buildings and floor treatments
Don't wait for T&C of MEP, but start a bit before (schedule mitigation)
Several TD deliverables are on NSS critical path for R-BOT (no float)
insertion tool, plugs, LSS etc

10. Monolith and Inserts All 42 ports needs to be plugged before BOT
16 complete ports with guides (15 instr + TBL)
26 complete ports with blind plugs
Neutron direction

11. Installation overview CF, TD & NSS
Overview illustrating the ongoing work from the SEC, TD and NSS in the main areas
D02, D03, D01 and E01/E02.
Red arrows indicates key dependencies/predecessors.
Working through summer for ESS critical path.

12. Integrated Schedule Bunker construction
Bunker team working closely with TD, NSS instruments and CF/SEC.
Building up bunker following access dates, in order to mitigate delays and to make the best of access dates => build it ”from outside and in”
Working in parallel with “TD& NSS joint monolith schedule”
NSS developing alternative bunker schedule (from inside and out)...
Plan B
6 months ‘open-bunker‘ for in-bunker instrument installation – more intense on D03 (west), likely to need multiple teams

13. NSS R-BOT July 7th 2022 (Bunker, TBL, 1st instrument)
Round up
TD R-BOT March 9th 2022
NSS R-BOT July 7th (Bunker, TBL, 1st instrument)
Installation sequence is complex but understood
Schedule is driven by access dates and equipment deliveries
No float from CF & TD to NSS “start of installation”
Multiple external and internal dependencies

14. Thank you

15. Schedule risks Schedule delay
zero float, working summers for critical path
Not fully detailed/resourced
Critical dependencies
access dates from CF (with no float)
area handovers from TD (with no float)
depends on CF access dates and TD procurement/IK deliveries
components delivery (inserts / bunker) - No agreed delivery dates with manufacturers yet
High degree of parallel work with Skanska & TD
NSS or TD does not own the building, SEC does. Majority of work before full access
Neighbouring SEC construction work
safety, shifts, coordination of transport of equipment, temporary solutions etc etc
Cleanliness during installation (parallel access)
Licensing process
Assumed that we can install Bunker R6 structure without the installation permit (non-radioactive components)

16. Mitigations – already implemented
Earlier access of bunker crane = install weather proof crane
Aligned the bunker installation sequence to follow access to areas
Improved schedule dependencies for installation, revisited what CF and TD work that must be done before NSS can start (now more aggressive schedule)
Joint TD/NSS installation will be done with parallel teams (D01 and D03 sides)
Agreed on alignment area in E01 for NSS & TD work with NBOA, IET, plugs
Simplified installation tool (TD insert installation)

17. Proposed rebaseline schedule for NBI. Installation (TG4 –> TG5) (V4
Proposed rebaseline schedule for NBI* Installation (TG4 –> TG5) (V4.0, 11th May 2018) from Installation workshop with teams building first 8 Instruments (8th May)
NSS access to E01
Start User Program (3NBI*)
Beam on Target
NSS access to D01
NSS access to D03
8 NBI* in User Program
Cave installation & fitout
OOB Guides & shielding
In bunker installation
Cold commissioning
NSS access to E02/2
Float for R-BOT:
TBL ~ 21 weeks
BEER ~ 7 weeks
CSPEC & BIFROST ~ 4 weeks
MAGIC & ESTIA ~ 1 week
NSS has no float for R-SOUP, but does have possible candidates
Manufacturing on critical path for BEER, C-SPEC, BIFROST & MAGIC, not E01 access.
West sector
Parallel installation in and out of bunker is assumed for LOKI, ODIN, DREAM & ESTIA. Extra labour & resources are needed
North sector
East and South sectors
* NBI = Neutron Beam Instrument

18. Proposed rebaseline schedule for Neutron Beam Instruments (V4
Proposed rebaseline schedule for Neutron Beam Instruments (V4.0, 11th May 2018) from Installation workshop with teams building first 8 Instruments (8th May)

Operation
West sector
North sector
East and South sectors
Current date
First access to NSS bldgs (E01)
Start User Program (3NBI*)
BOT & start HC of NBI*
8NBI* in User Program
Safest instrument choices to be Ready for SOUP in West sector (BEER, CSPEC, BIFROST & MAGIC) & East (ESTIA)
Most desirable instrument choices for early science highlights are in the South and North (ODIN, DREAM & LOKI). LOKI seems unlikely to make the deadline
Selection of first NBI for SOUP in March 2023
Knock-on delays to NBI: – 15 of ~ 1 yr and – 22 of ~ 1 ½ yr
* NBI = Neutron Beam Instrument

23. Inserts
Simplified tool and transportation route

24. Development since June
Several meetings discussing transport scenarios and solutions
Details such as roads, door widths, height differences, passage way dimensions have been looked into and compared.
TD has proceeded with simplified design of NBEX tool that can be used before activated area => IIT (insert installation tool)
Higher likelyhood to have it manufactured in time for installation
Cheaper (since we potentially need 4)
Weigh less (crucial since we need to transport from E01 to monolith area)
NSS held PDR for NBOA and moved into “tend & man.” phase for first instruments
Delays in SEC schedule for D-buildings with several months (6-17 months….)
Different alternatives have been discussed thouroghly last months…!
Optimised installation sequence for NSS/TD/SEC activities

25. Transport solution
Integration Workshop in E01 (Heimdal footprint) – E01 crane & temp. cranes
Pre-alignment (clean, checks etc)
NBOA aligned
Alignment lids sealed
NBPI windows mounted
Transport to south corner E01 (NMX footprint) – E01 crane
IIT with steel lid/protection cover
Transportation cradle with air-pads/cushion as needed (to be defined in “early tests”)
Transport from E01 to D03 south entrance – truck/boom truck on existing road
D03 south entrance to about “20m radius” – truck/boom truck with ramp
“20m radius” to IIT mounting knobs (monolith face) – Bunker cranes//boom truck
D01 inserts/plugs:
From E01 to D01 south entrance - truck/boom truck on existing road or
b. From D03 south entrance to D01 via passage way - truck/boom truck
Weather proofed buildings & bunker cranes !!
Subject for SEC
