Introduction The following site analysis report for the location on 148-154 Cardigan Street will illustrate the issues pertaining to its redevelopment and highlight the resources and paperwork required for the construction documentation. The table of contents divides the investigation of issues into four different groups including the below ground conditions for group 1, the surface conditions for group 2, the adjacent conditions for group 3 and the additional information for group 4. This report will be organised in a chronological manner in which resources and paperwork will be used in the process of construction documentation. It is composed of a list of consultants to achieve better understanding of the process prior to construction, which requires sets of different consultant drawings and contracts. Firstly, a certificate of title is mandatory and will be explained within the first part of the report illustrated with a summative site plan of 1:100. Then A-series will be required, consisting of architectural information including a site plan that has been informed by a land surveyor. The areas that could potentially require consultation will be in the first part of the report. A geotechnical engineer will then prepare G-series drawings and any arising issues will be presented after the land surveyor topics. In following, an S-series drawing will be created by a structural engineer and the site issues relating to this matter will be discussed after the geotechnical concerns. Also a fire safety engineer will be required to present an F-series drawing whose issues will ensue after the structural engineer matters. Additionally the town planning council will be involved to inform us what restrictions are in place in and around our site. Furthermore, the electrical engineer will produce a set of E-series drawings, the issues of site concerning this matter will be presented following the town planning affairs. In addition a mechanical engineer will be required to review the site issues and create a set of M-series drawings. These issues will be explained after the electrical matters. A Hydraulic engineer will then be engaged to produce a set of H-series drawings, and the issues of site relating to this will be following the mechanical topics. Likewise a cost consultant will be employed to generate a plan of budget for the issues of site, which will be presented after the hydraulic concerns. Then a building surveyor will review the drawings and their possible issues which will be presented following the cost consultant topics. Finally a dilapidation survey is required and will be explained at the end of the report. Â

Certificate of Title and Summative Site Plan

Figure 1  &  2  (Certificates  of  title  for  site  148-­‐154  Cardigan  Street)

Certificate of title should be submitted by the owner to the architecture firm prior to any work and will insure the site ownership and boundaries and historical context. In this case the site was historically divided into four different properties and as we can see it is now set as two different titles (Fig 1 & 2) that will be linked legally to make the site a whole.

Land Surveyor Observations Evidence of   previous   construction  on  site   with  topography  of   asphalt  on  car  park.  

Existing Impediments   including  an   electrical  pole  and   rail  fence.   Boundaries  of   adjacent  structures   horizontally  and   vertically.   Pits  for  gas  and   water  are  near  or  on   site.  

Analysis of issue observed Historical  evidence  of  four   different  properties  on  site.   Boundaries  may  be  lost   with  time  and  new   properties  built  either  side.     Also,  the  topography  of  the   site  needs  to  be  known  for   better  drainage  on  site  and   depth  of  footings.   Site  will  need  to  be  cleared   before  construction,  need   to  assess  if  these  items  are   on  site.  

Recommendations Assess where  the  site  ends  exactly   by  engaging  a  Land  surveyor  that   will  determine  the  exact  site   boundaries  by  finding  the  AHD   (L1),  setting  the  project  datum  (L2)   and  define  the  fall  of  the  property.  

Engage a  Land  surveyor  who  will   determine  if  impediments  breach   the  site  boundary.  

Adjacent structures  might   be  impeding  on  site   boundary.  

A land  surveyor  will  determine  if   the  site  boundaries  are  taken  up  by   adjacent  structures.  

Pits on  site  might  cause  an   issue  if  construction   damages  underground   system  or  stops  access  to   it.  Need  to  know  where   pipes  run  in  order  to   manage  weights  and   structure  positions.  

The Land  surveyor  will  identify   where  the  service  access  points  are   and  the  systems  running  to  them  in   their  exact  location  in  order  to   manage  construction.  

 

Geotechnical Engineer Observations

Evidence of  previous   construction  on  site  and   topography  of  asphalt  on  car   park.  

Soil conditions  are  poorly   observable  on  site,  only   through  trees  adjacent  to   site  on  Cardigan  Street.    

Analysis of  issue  observed  

Recommendations

Historically four  properties   were  located  on  site  and   today  asphalt  covers  it,   which  could  have  pre   existing  footings  or  remains   from  previous  properties   that  will  need  to  be   excavated  before   construction.   Unknown  soil  conditions   need  to  be  assessed  for   bearing  capacity  and  for   proper  footing  design.  

A geotechnical  engineer  will   provide  information  about   the  below  ground   conditions  and  what  needs   to  be  removed  before   construction.  

Geotechnical engineer  can   inform  us  of  the  soil   qualities  and  advise  on   appropriate  footings.   5  


Structural Engineer Observations  

Evidence of  previous   construction  on  site   through  topography  of   the  land  and  previous   building  outline.   Access  to  site  through   Cardigan  street  and   Grattan  place  laneway  

Boundaries of  adjacent   structures  vertically  

Analysis of  issue   observed   Footings  of  pre  existing   buildings  could  have   remained  which  will   need  to  be  excavated   before  construction   Construction  will  take   place  and  will  require   space  for  infrastructure   (storage)  and  unloading   zones  for  materials   deposited  by  trucks,   these  loads  on  streets   and  site  might  affect  it.   Two  properties  are  built   up  sharing  the  boundary   on  the  south  and  north   side  of  the  site,  their   footings  and  foundations   cannot  be  affected  by  our   construction  or  building.   The  south  side  building   has  an  underground  car   park  which  means   deeper  footings  

Recommendations Structural  engineer  will   implement  the  kind  of   footing  appropriate  for   site  and  recommended   by  geotechnical  engineer,   this  will  inform  the   extend  of  the  excavation.   Structural  engineer  will   determine  the   infrastructure  of   construction  and  the   proper  access  points  for   unloading  depending  on   loads.   Structural  engineer  will   determine  a  proper   management  of  site  to   not  affect  neighbouring   properties  or  services   and  establish  proper   footing  systems  for  our   building  depending  on   depth  and  angle  of   repose  in  context  to   adjacent  structures.  

Fire Safety Engineer Observations Existing impediments.   Supposedly  shared   boundary  wall  on  north   side  of  property  (Fig  3).    

Analysis of  issue   observed Our  building  cannot   affect  neighbouring   properties  in  any  way.   Fire  has  to  be  contained   within  our  property  if  it   occurs;  this  shared  wall   needs  to  have  adapted   properties  to  these   conditions.

Recommendations Fire safety  engineer  will   establish  an  appropriate   wall  (F1)  if  it  is  to  be   shared  to  town  planning   standards  and  come  up   with  fire  safety   emergency  routes  and   regulations  on  site.

Electrical Engineer Observations  

Services positioned  on   and  around  site  

Existing impediments:   electrical  pole  at  rear  of   site  (Fig  4)  

Analysis of  issue   observed   Access  to  services  needs   to  remain  clear  and   unobstructed  during   construction;  loads   cannot  affect  the   underground  system.  

Recommendations

Electrical engineer  will   inform  us  of  the  position   of  the  operative  pits  (E2)   and  their  underground   system.  Their  bearing   load  will  be  defined  and   not  violated  during   construction   Electrical  pole  at  rear  of   Electrical  engineer  will   site  is  very  close  to  site   determine  if  this   boundary  and  electrical   electrical  pole  (E1)  is  an   lines  flow  loosely  along   issue  and  how  to  resolve   site  boundary  and  across   it  by  either  making  a  plan   Grattan  place,  this  could   to  respond  to  this  or   cause  issues  during   establish  a  report  for   construction  and  for   town  planning  asking  for   future  building.   its  removal.

Mechanical Engineer Observations  

Amenities of  adjacent   structures,  air   conditioners  (Fig  5)  on   both  properties  next  to   site.  

Analysis of  issue   observed   Air  conditioners  might  be   affected  and  obstructed   during  construction,  care   needs  to  be  taken  for  this   not  to  occur  

Recommendations Mechanical  engineer  will   elaborate  a  manner  in   which  to  not  affect   neighbouring  air   conditioners  (M1)  during   construction.  

Figure 5  (Air  conditioners  on  neighbouring  property  on  north  side  of  site)  

Hydraulic Engineer Observations Services/ existing   impediment:  Water  pit   (Fig  6)  on  site  near   northeast  corner.    

Analysis of  issue   observed Service  needs  to  be   accessed  during   construction,  the   underground  pipe   system  cannot  be   damaged  and  the  pit   cannot  be  obstructed  by   construction.  

Recommendations Hydraulic Engineer  will   make  the  connection   with  the  water  pit  (H1)   and  define  its  location   and  bearing  capacity  for   construction  or  establish   if  its  position  is   detrimental  to  site.

Cost Consultant Observations Access for  users  and   construction  (Fig  7).      

Amenities of  adjacent   structures  and   construction  site.    

Analysis of  issue   observed During  construction   access  will  be  limited  on   site  for  users  and   constructers  alike.   Causing  issues  in  the   neighbouring  community   and  obstruction. Air  conditioners  (M1)   exist  on  both  properties   adjacent  to  our  site  our   construction  might   damage  them.   Construction   infrastructure  has  to  be   planned  on  site  and  on   adjacent  site,  the  cost   ensued  must  be   acknowledged.

Recommendations Cost consultant  will   assess  a  budget  for  hiring   the  space  taken  up  as   construction   infrastructure. Cost  consultant  will   evaluate  a  budget  for   possible  damage  repairs   on  adjacent  amenities   and  hiring  infrastructure   for  construction.

Analysis of  issue   observed During  construction   access  will  be  limited  on   site  for  users  and   constructers  alike.   Causing  issues  in  the   neighbouring  community   and  obstruction.

Recommendations

Construction cannot   affect  surrounding   properties,  care  has  to  be   taken  by  builders  and   construction   infrastructure  has  to  be   managed  as  to  not   damage  adjacent   structures

Building surveyor  will   establish  a  program  for   construction   management  in  regards   to  protecting   surrounding  sites.

Building surveyor  will   submit  a  proposal  as  to   why  these  spaces  and   access  is  needed  for   construction  and  how   they  will  be  managed.
