       SPeAR®  does  not  offer  guidelines  for  sustainable  design,  rather  it  focuses  on  multi-­‐criteria  appraisal,  and  is  used  in  combination  with  ARUP's  sustainability  consulting  services.

Summary

The  Sustainable  Project  Appraisal  Routine  (SPeAR®)  is  a  holistic  sustainability  decision-­‐making  framework  to  support  project  development  and  communicate  outcomes.  It  is  a  software  tool  based  on  quantitative  and  qualitative  appraisal.  Results  are  presented  graphically  on  the  SPeAR®  diagram  using  a  traffic  light  system  to  indicate  sustainability  performance  against  key  themes.

Organisations

Function

All  Infrastructure

       Arup  consultants  engage  with  the  client  on  sustainability  aspirations.    Following  development  of  design  options,  these  are  assessed  using  the  SPeAR®  framework.          The  assessment  boundaries  are  defined  and  key  stakeholders  are  identified.        A  Materiality  Review  is  used  to  identify  relevant  indicators  and  sub-­‐indicators.          Data  gathering  on  performance  is  conducted  through  desktop  study,  site  visits  and  through  a  SPeAR®  Workshop.          The  resulting  SPeAR®  diagram  enables  discussion  on  underperforming  areas  and  the  Appraisal  Report  poses  recommendations  for  selection  or  performance  improvement.

Deployment  &  developments

         SPeAR®  is  currently  offered  as  part  of  Arup's  sustainability  services.  However  the  software  may  become  commercially  available  on  the  web.          It  will  be  targeted  to  clients  who  want  to  employ  Arup's  services  as  well  to  help  with  tailoring  the  assessment,  interpretation  and  action  on  results.

Use  with  other  tools

       Used  for  sectors  that  do  not  yet  offer  rating  &  certification,  or  where  a  client  wants  to  test  readiness  for  certification    (e.g.  BREEAM)  and  improve  performance.

       Indicators  comprised  of  3-­‐6  sub-­‐indicators  assess  project  performance  against  a  traffic-­‐light  system  scale.          Regulatory  compliance  is  set  at  zero  of  scoring  scale.  Materiality  enables  the  selection  and  elimination  of  indicators.          There  is  no  weighting  of  indicators  although  elimination  of  sub-­‐indicators  puts  greater  importance  on  others.  There  is  no  overall  sustainability  scoring.          Results  for  each  indicator  are  presented  on  the  SPeAR®  wheel.  The  software  generates  a  tabulated  summary  of  the  input  data.

       These  come  in  the  form  of  ARUP  sustainability  consulting  services  which  guide  in  the  use,  tailoring  and  interpretation  of  SPeAR®  results.

Sustainability  criteria

       SPeAR®  is  based  on  23  core  indicators:          1.  Social  (community  facilities,  culture,  form  and  space,  health  and  well-­‐being,  transport,  stakeholder  engagement)          2.  Environmental  (soil  and  land,  biodiversity,  waste,  materials,  water  use,  wastewater,  energy,  climate  change,  air  quality)          3.  Economic  (economic  effect,  facilities  management,    site  selection,  employment  and  skills,  equality,  governance  and  reporting,  risk,  procurement)  

Level  of  materiality  (tailoring)

       Materiality  is  assisted  by  an  Arup  sustainability  professional    to  ensure  unbiased  assessment,  regulatory  compliance,  stakeholder  interests,  innovation  and  best  practice.          The  client  chooses  which  indicators  to  consider,  although  omission  needs  to  be  justified.  Core  indicators  relevant  to  most  projects  are  included  and  clients  can  choose  from  additional  sector  or  geography-­‐specific  indicators.          There  is  a  choice  to  only  do  a  SPeAR®  Social  or  Environmental  Assessment.

Project:  Site  selection  for  a  new  reservoir.Client:  Bristol  Water.

Brief  description:            SPeAR®  was  used  for  site  selection  of  a  potential  new  reservoir  for  Bristol  Water.    The  client  had  selected  a  number  of  sites  and  wanted  a  sustainability  appraisal  of  each  option  to  inform  selection  of  the  final  site.  Several  sustainability  issues  were  considered  for  each  site  including  their  ecological  capacity,  energy  and  carbon  footprint  (e.g.  from  pumping  water  to  treatment  works),  transport  links  for  materials  and  whether  the  site  was  near  communities  which  could  use  it  as  recreational  facility.  SPeAR®  enabled  the  identification  of  risks,  impacts  and  opportunities  and  advised  in  the  selection  of  the  final  reservoir  site.
