Project  1:  Introduction  to  Drawings  &    Construction  Industry  

•  Cynthia  Fong  (group  leader)  •  Nur  Azreen  •  Michelle  Ee  •  Lim  Zia  Huei    •  Nadhirah  •  Riven  Hau  

•  a  person  trained  to  calculate  construction  measurement  like  a  calculator    •  work  closely  with  landscape  architects/designers,  engineers  and  builders    

•  calculates  the  cost  and  quantity  of  materials  and  labour  needed    

•  read  design  drawings  to  estimate  cost  of  project  

What is QS?

Roles & Responsibilities

•  measurements  &  estimations  

•  manage  &  control  cost  within  construction  project  

•  produces  Bill  of  Quantities  (BQ)  

•  preparing  and  analyzing  costing  for  tender  

•  study  drawings  about  new  buildings  before  construction  project  starts

Processes Qs are involved

discussion  

outline  proposal  

scheme  design  

detail  design  

tender  action  

•  ensure  project  is  possible,  technically  &  Oinancially  

•  carry  out  studies  of  requirements,  site  conditions,  planning  design  &  cost  

Purposes:

Task to be done:

Outline Proposal

•  determine  general  approach  to  layout,  design  &  construction  

•  obtain  authoritative  approval  from  client  on  the  outline  proposals  and  accompanying  report  

•  develop  the  brief  further  •  carry  out  studies  on  user  

requirements,  technical  problems,  planning,  design  &  costs  

Purposes:

Task to be done:

•  complete  brief  &  decide  on  proposals  (planning  arrangement,  appearance,  constructional  method,  outline  speciOication  &  cost)  

•  obtain  all  approvals  

•  full  design  of  the  project  by  architect  

•  preliminary  design  (engineers)  •  preparation  of  cost  plan  •  full  explanatory  report  •  submission  of  proposals  

Purposes: Task to be done:

•  obtain  Oinal  decision  on  every  matter  related  to  design,  speciOication,  construction  &  cost  

•  complete  cost  checking  of  designs

Task to be done:

Tender selection

Types of drawings QS read

1.  architectural  drawings:  preliminary  drawings  

2.    tender  drawings    

3.    contract  documents  

1.  Architectural drawings

v  It  is  a  technical  drawing  of  a  building  that  an  architect  draw  according  to  the  clients’  requirements.    

ü  QS  will  have  to  then  estimate  the  cost  of  the  building  while  mechanical  engineers  &  structural  engineers  prepare  the  structural  requirements  etc.  

2. Tender drawings When  the  clients  agree  to  the  preliminary  drawings,  the  drawings  are  then  proceeded  to  a  more  developed  one  &  with  clearer  details.    

Tender  drawings  are  therefore  completed:    

developed  architectural  drawings  +    

the  structural  engineer’s  drawing  +  

 M&E  engineer’s  drawing  

ü  These  are  then  ready  for  bidding  and  QS  will  quantify  &  cost  out  of  building.  

If  clients  disagree,  redesign  until  meets  requirements  

Bills of Quantities (BQ)

•  provides  fair  &  accurate  system  for  cost  analysis  

           

•  assists  tenderes  in  the  calculation    of  tender              

•  issued  to  tenderes    to  prepare  price    

ü  after  bidding,  QS  will  run  through  another  quick  tender  evaluation  which  actually  means  QS  will  evaluate  &  Oilter  the  tender  once  more.      

ü  a  suitable  contractor  is  then  selected  by  comparing  the  BQs  for  reasonable  prices  as  well  as  good  quality      

3. Contract documents

The  tender  drawings  are  converted  into  contract  drawings  with  an  appendix  if  necessary.    

Contract  is  the  formal  agreement  between  the  buying  organization  and  the  supplier  setting  out  what  services  and  products  the  supplier  is  contracted  to  deliver  and  within  the  contract  price.
