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
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.

Town Planning Observations
Analysis of issue observed Access to site for users Construction and construction through infrastructure will take Cardigan street and up space and will need Grattan place proper Boundaries of adjacent structures horizontally and vertically
Amenities of adjacent structures and construction site.
Town planning will obtain the permits for space needed for construction infrastructure and access If adjacent structures are Town planning impeding on site consultant will assess if a boundary a legal claim claim to remove existing needs to be assessed if structure is possible this can be removed or if relative to right of use. it should remain. Construction will take Town planning will give place on site and on permit to which spaces adjacent sites, the can be used for adjacent sites might be infrastructure and what damaged or might not be loads can be used on able to support the these spaces. weight of infrastructure, on roads or service pits.
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.
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.
Figure 6 (Water pit on northeast corner of 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.

Building Surveyor Observations Access to site through Cardigan street and Grattan Place (Fig 7)
Boundaries of adjacent structures horizontally and vertically.
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.
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.
Dilapidation Survey A dilapidation survey is a report accounting for all the existing conditions on site and on adjacent sites and structures. It should be undertaken prior to any construction and record existing faults so that the construction company, architect and client cannot be help accountable for existing damages. It is also used to obtain information on adjacent structures and their damages of which the causes can be analysed and assessed so that our building can respond to these conditions accordingly. This report should be given to the owners of neighbouring properties and signed so that they acknowledge their existing damage.
