## ORLaNDHow to Proceed?Estimated Cost and Schedule

**Facility Advisory Committee Review**
**March 2001**
**Jim Beene**

## Effect Of SNS Constraints:  Possible Construction Scenarios

**All heavy construction must be completed before instruments are installed in north field**
**Next window for construction is at first major shutdown for SNS upgrade (~2011)**
**Only credible staging scenario (for close bunker) involves completing heavy civil construction first (bunker shell), completing facility in phase 2.**

## Background of Cost Estimate

**Regardless of division of project into facility and experiments (perhaps NSF funded) DOE requires an estimated a total project cost estimate as part of proposal.**
**Includes the large detector experiment plus two representative small experiments (~50% of TPC).**
**Actual experiments will be selected based on proposals by the scientific community to a program advisory body.**

## Background of Cost Estimate

**TPC estimate developed for DOE can be divided two ways**
**Time critical vs. non-time critical aspects**
**Useful for developing funding profile to fit SNS schedule**
**Facility construction vs experiments**
**Best way to think about funding, since experiments will be proposed by independent groups, and may be funded independently**

## Basic Cost Estimate (S&W) 

**TPC $64M escalated**
**$30 M Total Facility Cost**
**$34 M for 3 experiments**
**Separation not clear and bright**
**Facility includes 2 kton detector tank **
**Facility includes up to ~$6m in costs that might legitimately be associated with experiments**

## Comparison of two estimates

**Both estimates in $FY01**
**S&W (three detectors costed)**
**$28M facility   **
**$31M experiments (3)**
**$59M Total**
**ORNL engineering (two detectors costed)**
**$21M facility**
**$32M experiments (2)**
**$52M Total**

## Response to Constraints

**In order to deal with funding constraints**
**Develop a two-phase scenario**
**Identify the minimum set of  time-critical (SNS window constrained) aspects for Phase 1 funding (<15% of TPC)**
**Phase 2 is not constrained by SNS window**
**Cost scenarios do not include added cost of delaying phase 2 (delay not specified)**

## ORLaND Two-phase breakdown (based on S&W estimates)

**Phase I  ****(time critical)****	**** ****	****($8M)**
**Large underground detector hall**
**Cylindrical structure ~110’ x 78’**
**Includes basic civil const. & utilities**
**Sized to accommodate 2 kton det.**
**Size not primary cost driver**
**Phase 2 ****(not time critical)****	**** ****($56M)**
**Balance of construction ****	**
**Tank for 2 kton detector ****	**
**Tank farm for detector liquids****	****	**
**Straw-man experiments. ****	**
**Instrumentation of large tank****	**
**Two additional detectors / experiments**
**Data acquisition, electronics, ...**

## ORLaND Cost Breakdown($M)

- *Construction cost includes fabrication and installation of 2 kton
-    tank for LDC

## ORLaND Phased Cost Breakdown ($M) 

**• ****Detector hall only**
**• ****All SNS schedule critical construction in Phase 1**

## A possible ORLaND schedule

## ORLaND Project Funding ScenariosTwo-phase breakdown profile 

**• ****Based on Stone and Webster study**
**• ****Phase two includes full implementation of three experiments  **
**	****> one ~2000 ton, two 100-200 ton. **** **

## ORLaND - SNS Interface Status March 2001Critical Issues

**Formal recognition of ORLaND on SNS documents**
**Final, precise location for ORLaND detector hall**
**Definition of access to ORLaND detector hall**
**Location of surface tank farm**
**Restriction on surface facilities at detector hall?**
**Required to provide support for n-scattering instruments?**

## Where do we go from here?
