Construction
Planning
Pre-Construction
Planning
A thorough and rigorous analysis of
the construction methods proposed and restraints has taken place. From this planning, a site plan has
been developed for the construction phases. The site plan identifies the
construction requirements which include, but are not limited to:
· Site egress and access
· Crane locations and size
· Crane loading zones
· Public safety and amenity maintenance
· Material hoist location and size
· Concrete placing booms location
· Temporary hoardings or fencing for the
protection and safety of the public
Dilapidation
Survey
An existing conditions survey has been
carried out and a detailed report and photographic records of adjoining
properties has been maintained.
Public &
Property Protection
As part of the construction of the new dwellings,
excavation will be completed in order to achieve the extent of the basement
works.
As part of this excavation, we will utilise the
following methodology for the protection of the surrounding properties.
The protection of the surrounding properties land
and footings will be achieved by ensuring a 45 degree angle is maintained with
the surrounding soil walls.
Should there be a requirement for sheet piling
in order to reinforce the neighbouring land whilst excavation is being
completed, this will be done.
Secure Temporary Fencing will also be erected around
the perimeter of the site in order to clearly establish boundaries and safety
zones. Fencing will also maintain an authorized access only classification of
the site.
Safety signs will be displayed clearly with all
safety requirements stated clearly for any personnel wishing to access the
site.
We anticipate the excavation works to be completed
over a period of approximately 10 days, with the entire construction to be
completed over a period of approximately 10 – 12 months.
The
protection of all council infrastructures including overhead cables and
existing services will be managed to ensure that all infrastructure will be
retained in the same condition at the completion of the project.
Temporary Fences/Hoarding
The Temporary fencing
used is a series of Temporary Mesh Panels which are 2000mm high x 2500mm long
with an 1800 mesh infill. The Fencing is fixed by concrete safety blocks 130mm
high x 230mm wide x 600mm long.
The following requirements are project specific and will be
implemented by the project construction team during the project.
These include: Tender

Approach to
Quality Assurance During Construction
The Construction Quality System addresses all project activities from commencement to completion, using Constructions standardised activity list. Design Management protocols are contained with Construction Management Plan.
Each project’s requirements are planned, monitored and recorded by
a member of the project team.
Method for
ensuring Contractors and Major Suppliers Compliance with the System
To ensure compliance with the Client’s requirements, we will
require that all major suppliers and Contractors develop and submit
documentation for their respective trade packages to satisfy the Quality
Requirements established prior to the commencement of work. The extent of subcontractor submissions
is determined by the subcontractor QA Risk Schedule. Subsequently a handout of subcontractor requirements is
forwarded for submission.
This may include a Project Specific Quality Plan, Work flow
diagram or Inspection and Test Plans, and Inspection Records / Check sheets for
high risk trades identified by the site team.
Site QA Coordinator will be responsible for ensuring that all
Contractors / Suppliers are aware and have the capacity to conform with the
nominated quality requirements set prior to the commencement of works. The Site
QA Coordinator will confirm that an appropriate Quality System is implemented
and maintained by each contractor in accordance with the procedures set out in
their Project Quality Documentation.
A Schedule of Typical Subcontractor compliance requirements is
prepared. The respective Site Supervisor will use this tool for coordination of
various trade packages and track at various construction milestones for
submission and compliance to specification requirements
Inspection and
Testing Phases:
Where required by contract, we provide a schedule of typical contractor compliance requirements summary that includes provision for Client / Representative or Consultant notification for hold points, witness points or testing (on-site & off-site). The Site Supervisors / Manager issues notification to the appropriate Consultant / Authority / Clients representative for inspection of site works at the assigned times.
All required test results are forwarded to relevant parties.
Incoming
inspections will be carried out to ensure that materials, goods and equipment
are identified, inspected and / or tested prior to storage or installation.
Products or goods that do not comply with the inspection requirements are
segregated and removed off-site as soon as possible to prevent inadvertent use.
Goods received must be in compliance with the project
specification & / or Australian Standards.
In-process
inspections shall ensure that materials, goods, equipment and workmanship are
identified, inspected and / or tested either during installation on-site or
during manufacture or fabrication at the Suppliers’ premises.
Throughout the construction phase, non-conformances will be
identified along with recommendations for close out.
NCR reports with be
issued to ensure that they are disposed of in a timely manner.
Non-conformances may also include Client / Representative or
Consultant raised issues, which will be recorded and expedited in a similar
manner. Disposition of such issues will be prompt as per the stipulated period.
Final Inspections are
carried out upon completion of a specific operation/area, to ensure that the
finished product meets the criteria of the contract documentation (ie: Project
specification & Australian Standards). Further, final inspections shall
verify any prior inspections & / or tests and that any rework has been
completed. Defective works detected as a result of final inspections shall be
rectified prior to handover.
At practical completion, As Constructed drawings, O & M
Manuals and Warranties shall be submitted to the client in the quantities and
format required.
Audit
Procedures
To ensure compliance with the established quality systems, we will undertake systematic Auditing / Monitoring activities on Inspection and Test activities carried out by Contractors / Suppliers as outlined in agreed audit schedule. Audits will be conducted on-site and (where applicable) at the contractor’s supplier’s premises.
The audits will monitor, evaluate and verify that all aspects of
the Contractors / suppliers Quality Documentation, Work flow diagrams,
Inspection and Test Plans and Check Sheets are being applied. The quality
audits will be documented when carried out and the results of those audits
shall be made available to the appropriate persons.
The audits will be also monitor, evaluate and confirm that all
aspects of the Quality System, Construction Management Plan, Inspection and
Test Plans and Check Sheets are being applied. The Quality Systems Manager will
be responsible for implementing any corrective action required as a result of
the internal audits.
Auditing /
Surveillance of Contractors:
The construction team will utilise the “Subcontractor QA Risk Schedule”, to focus on the critical / high risk trades. These are not limited to the following:
Structure works
Structural steelwork
Services
Plastering
Waterproofing
Roofing
Special finishes
The audits will comprise the collection of evidence, the document of observations and the determination and reporting of discrepancies and non-compliance.
Audit reports will be generated to verify that audit activities
have been carried out and to identify the activity being audited, the date of
the audit and the observations within a reasonable period (but no later than 7
days) following the audit.
Reporting
Site Team meetings are undertaken on a regular basis, at which Quality issues and status are reviewed and where required are noted on records of minutes, including:
Contractor / Suppliers Documentation Status
Implementation Issues
Status of Non-Conformances
On a regular basis the Site QA Coordinator reports to the Quality Systems Manager on the following on agreed reporting format.
Total number of contracts let
Total number of QA plans received
Total number of QA plans reviewed
Total number of QA plans accepted
Number of QA Audits on subcontractors /
suppliers scheduled
Number of QA Audits on subcontractors /
suppliers completed
Total number of outstanding non-conformances
We will also ensure that all Contractors will provide prior to the completion of each month, a written report summarising the effectiveness of the quality plan and status of project quality records, which shall include but not be limited to:
% works completed
Areas signed off and handed over
Incomplete works / defects
Any of the above reports can be made available to Client upon request.
