Principal  Contractor:   Jones  Brothers  (Henllan)  Ltd    Design  Responsibility:   Client    Client:   Welsh  Government    Description  /  Key  Delivery  Features:   JBHL  were  engaged  by  WAG  to  undertake  prestigious   infrastructure  

construction  work  on   the  prestigious   SA1  Waterfront  Development  in   Swansea.   The   work   entailed   the   construction   of   roadways,   foul  and   surface   water   drainage   systems,   provision   of   utility  infrastructure  and  extensive  landscaping.  

 Relevance:   The   scheme   involved   working   in   deep   excavations,   tidal   working,  

traffic   management,   extensive   landscaping,   street   lighting   and  signage.   The   actual   construction   site   was   alongside   Fabian   Way  which   is   an   extremely   busy   thoroughfare   that   demanded   robust  traffic   management   arrangements.   The   site   was   fenced   off   to  prevent  access  by  unauthorised  persons  whilst  maintaining  access  to  The  Port  Authority.    

 Other  significant  elements  of  the  contract  included:    • Construction  of  a  reinforced  earth  ‘Geogrid’  retaining  wall.  • Construction   of   a   900mm   storm   water   outfall   which  

discharged  to  sea  via  a  dock  headwall.  This  outfall  was  up  to  4m  deep   in   places   needing   box   shuttering   and   dewatering  facilities.  

• Construction   of   a   modular   precast   concrete   box   culvert  sewerage  system.  Due  to  the  granular  nature  of  the  ground  and  close  proximity  of   the  sea,  continuous  dewatering  was  required   throughout   the   construction   phase   with   waste  water  discharged  to  stilling  lagoons.  

• Provision   was   made   for   utility   infrastructure   and   JBHL  coordinated  with  the  Utility  Companies.    

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

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

• Detailed   planning   and   programming   for   the   contract  including  emergency  mitigation  measures.  

• Maintaining   a   close   working   relationship   with   utility  representatives   to   help   mitigate   potential   delays   on   their

part.      The  following  challenges  were  encountered  during  the  contract:    • Working  safely  in  deep  excavations.  We  used  telescopic  box  

type  shutters.  • Artificially   hard   material.   Although   demolition   had   taken  

place   on   site,  we   came   across  many   examples   of   concrete  strip  foundations  and  slabs.    

• Maintaining   traffic   flows  within   Fabian  Way.  We   restricted  work   on   the   confines   of   the   site   to   weekend   working   as  traffic   flows   were   such   that   any   restriction   during   the  working  day  would  cause  severe  congestion.  

 All  surplus  excavated  materials  on  site  were  recycled  and  used  either  as  fill  or  for  landscaping  purposes.  This  sustainable  approach  was  in  compliance   with   our   Site   Waste   Management   Plan   and   was   fully  endorsed  by  the  EA.      There   was   sufficient   room   on   the   site   to   create   shallow   stilling  lagoons   where   the   water   from   the   continuous   dewatering   activity  was   discharged.   This   was   far  more   robust   than   installing   de-­‐silting  capability  within  the  pumping  regime.        

   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:  

 • Traffic  management  • Street  lighting  • Traffic  signage  • Mechanical/Electrical  work  on  PS  • Surfacing  works  • Security  arrangements.  

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