 Method
 

 
DEFINITION
 
The
 term
 “Design-­‐Build”,
 is
 used
 to
 refer
 to
 the
 procurement
 process
 in
 which
 an
 
owner
  of
  a
  project
  establishes
  a
  contractual
  relationship
  with
  a
  single
  entity
  for
  both
 
design
  and
  construction
  services.
  The
  entity,
  or
  “designer-­‐builder”,
  is
  not
  only
 
responsible
 for
 the
 construction
 phase
 but
 also
 the
 design
 of
 the
 project.
 
The
  Design-­‐Build
  entity
  can
  be
  arranged
  in
  many
  ways
  depending
  on
  the
 
agreements
  established
  between
  the
  owner
  and
  the
  Design-­‐Builder.
  For
  example,
  the
 
design-­‐builder
  may
  be
  a
  single
  company
  or
  it
  may
  be
  a
  consortium
  or
  joint
  venture.
 
Additionally,
 the
 design-­‐builder
 may
 or
 may
 not
 have
 its
 own
 design
 and
 construction
 
internal
 division;
 instead,
 an
 engineering
 design
 firm
 may
 subcontract
 a
 contractor
 for
 
the
  construction
  phase,
  or
  vice
  versa,
  a
  construction
  firm
  may
  subcontract
  the
  design
 
work.

BRIEF
 HISTORY
 
Design-­‐Build
 has
 been
 used

 when
