Other significant elements of the contract included: Rock excavation with a rock chain trencher to maintain programme and recycle material. The airfield alongside the project had to remain operational for the duration of the contract with no possible overlap between construction activities and operational use. A road closure was secured from Ceredigion CC for a substantial section of the new rising main. This was progressed following public / stakeholder consultation. Challenges Met / Solutions Provided: Risk was minimised during the project by: Full site investigation to determine location of buried utilities and other infrastructure.

Maintained a close working relationship with statutory undertakers to minimise potential delays. The following challenges were encountered during the project: The old derelict airfield buildings were found to be a bat roost that resulted in employing bat expert, changing our programme and erecting bat boxes as mitigation measures.

Principal  Contractor:   Jones  Brothers  (Henllan)  Ltd    Design  Responsibility:   Client    Client:   Welsh  Government    Description  /  Key  Delivery  Features:   A  new  Technology  Park  at  the  former  MOD  airfield  at  Aberporth.  The  

work   involved   the   removal   of   all   existing   WW2   infrastructure   and  creation  of  new  highway  infrastructure.  Work  included  a  pressurised  200mm  diameter   sewage   rising  main  was  also   laid   from   the   site   to  the  nearest  sewerage  system,  some  2km  away.    

   Relevance:   The   contract   involved   a   whole   array   of   competencies   including  

demolition,   earthworks,   highway   establishment,   and   provision   of  foul   and   surface  water   drainage,   utility   infrastructure,   landscaping,  street  lighting  and  signage.  

     Other  significant  elements  of  the  contract  included:  • Rock   excavation   with   a   rock   chain   trencher   to   maintain  

programme  and  recycle  material.  • The  airfield  alongside  the  project  had  to  remain  operational  

for   the   duration   of   the   contract   with   no   possible   overlap  between  construction  activities  and  operational  use.  

• A   road   closure   was   secured   from   Ceredigion   CC   for   a  substantial   section   of   the   new   rising   main.   This   was  progressed  following  public  /  stakeholder  consultation.    

 Challenges  Met  /  Solutions  Provided:   Risk  was  minimised  during  the  project  by:  

•     Full   site   investigation   to   determine   location   of   buried  utilities  and  other  infrastructure.

   The  following  challenges  were  encountered  during  the  project:  •     The   old   derelict   airfield   buildings   were   found   to   be   a   bat  

roost   that   resulted   in   employing   bat   expert,   changing   our  programme  and  erecting  bat  boxes  as  mitigation  measures.

contents  as  well  as  disposing  of  adjacent  contaminated  soil.  • A   TM   Plan   was   developed   to   maintain   traffic   flows   and  

minimise   disruption   to   road   users   including   pedestrians.  Special  consideration  was  given  to  seasonal  requirements  of  the  major  trunk  road  during  the  summer  months.  

• Asbsetos  removal  by  our  specialist  ARCA.    

To  minimise  our  carbon  footprint,  all  surplus  excavated  material  on  site  were  recycled  and  used  as  fill  over  landscaped  areas.  Excavated  material  from  the  trencher  operation  was  not  acceptable  for  use  as  backfill  within  the  highway  and  was  returned  to  the  airfield  site  and  reused.      We   worked   together   as   an   integrated   team   with   the   Client   and  designers  to  an  agreed  timeline  and  expected  quality  standards.  Our  experience   on   the   DCWW   framework   aided   our   efficiency   and  understanding  of  the  pipeline  element.    The  efficiencies  and  improvements  implemented  included:  •     Allocating   adequate   and   appropriate   resources   to  mobilise  

the   contract   and   maintain   programme   outputs.   We   made  effective   use   of   the   programme   to   address   potential  slippage  concerns.  

•     Involvement  of  an  ecological  bat  expert  at  an  early  stage  to  mitigate  lengthy  delays  to  the  contract.  

     Principal  Supply  Chain  Partners:   JBHL   delivered   substantive   elements   of   the   contract   using   our  

directly   employed   workforce   and   extensive   selection   of   modern  construction  plant.  The  following  activities  were  subcontracted:  • Trenching  Contractor  • Traffic  Management  • Street  Lighting  • Mechanical/Electrical  work  on  Pumping  Stations  • Surfacing  works  • Bat  Surveyor  

 All   subcontractor   activities   were   managed   in   accordance   with   our  ISO  accredited  processes  and  procedures.    

 References:   Mr  Brian  Evans,  Senior  Construction  Executive  with  WAG:  ‘Just   a   short   note   to   thank   you   for   your   company’s   efforts   in  achieving   maximum   output   within   the   contract   period   for   works  recently  completed.  For  my  part   I  am  pleased  with  the  organisation  which  you  set  up  and  executed  on  the  site  in  carrying  out  the  works’.
