Construction and Maintenance of State Roads.

The Project Specification is to contain all the specific requirements of the project.

T16.2 OBJECTIVE

Whilst the objective of this Specification is to provide clear directions on what is expected to be

covered in a project specification it is not an exhaustive document as each project will have

individual requirements however it does contain the minimum topics to be considered when

preparing a Project Specification.

T16.3 REFERENCES

T16.4 GENERAL REQUIREMENTS

This purpose of a Project Specification is to clearly detail the project scope, relevant payment

provisions and the technical requirements of the project. It will, as far as possible, detail only

the requirements relating to the finished product or desired outcome and not prescribe the

method of delivery.

Generally the Project Specification is not to contain clauses relating to items covered in the

Conditions of Contract, such as liability matters, time provisions or liquidated damages.

The Project Specification shall reference all relevant DIER Standard General, Roadwork’s and

Bridgeworks Specifications, including number, title and issue date. Any approved project-

specific amendments to the General, Roadworks and Bridgeworks Specifications shall be

clearly detailed, ideally in the one location for ease of reference.

Wherever possible, terminology used in the Project Specification shall be consistent with the

terminology used in the relevant DIER Standard Specifications.


TASMANIA



June 2012


The Project Specification shall not contain references to products, particularly proprietary

products.

The Project Specification shall not contain references to Australian Standards or other

publications that are referenced in DIER Standards Specifications unless there is a need to

address specific project requirements. Where such references are required they shall be

specific to the relevant clause(s) shall not be a general reference.

All DIER standard General, Roadworks and Bridgeworks Specifications referenced in the Project

Specification shall be the current, approved versions downloadable from DIER’s internet site.

Draft standard specifications may only be referenced when there is a specific need to do so

(e.g. trials of products or introduction of developing/evolving standards) and then only on

approval from DIER.

T16.5 PROJECT SPECIFIC DETAILS - GENERAL

The specific details of the Project Specification shall be prepared individually for each project.

T16.5.1 Description of Works

This item should provide a detailed description of the work in the project, including the

location, type, extent and limits of the work.

The description of work should include a general overview of the locality of the project and

refer to the relevant DIER Link Map contained in an appendix to the Project Specification.

The description of work should define what the general type of work is, in accordance with

Standard Specification G1 General Provisions, Clause G1.2.1 i.e., Construction or Maintenance,

as this influence the Limits of Contract. The Limits of Contract for a construction project

should be shown on the Drawings or described in detail in the Project Specification.

The clause should include a broad description of construction activities that define the scope,

such as earthworks, traffic control, flexible pavement construction, drainage, sprayed

sealing/asphalt, guard fence/WRSF, gabion wall construction etc.

The description of work should cover all elements of the work required to deliver the project.

T16.5.2 Nature of Project

This Clause should indicate whether the Project is Schedule of Rates, Lump Sum or a hybrid of

both.

T16.5.3 Design Features

For road works, this clause describes the principal design features e.g. lane/carriageway

configuration, medians, wire rope safety fence separation, grade separation of intersections

etc. For bridgeworks, this clause would describe the design features of the work including type

of structure, width and lane configuration, span lengths, fixed and/or movable expansion

joints, substructure, horizontal and vertical alignment.

Design features need not be detailed but should provide sufficient detail to convey to the

Contractor the design elements which may have an influence on the construction methodology.

T16.5.4 Work Not in Project

This clause should identify those items of work which are shown on the Drawings or are

directly associated with the project but which are not included in the project.


TASMANIA

This may include such works as traffic signal construction or installation of Intelligent Transport

System (ITS) infrastructure.

Works not in Project should be noted on the Drawings.

T16.5.5 Contractor Site Facilities/Working Area

The Working Area is usually not specified in the Project Specification but is generally defined in

Standard Specification G1 General Provisions Clause G1.5.2. However, with some projects,

there may be a need to define a specific area which may have benefits to the Projector and

may reduce cost to the Principal (e.g. the Principal may make available a house and environs

which has been purchased as part of the project and scheduled for demolition but which is

being made available to the Projector as a Projector Site facilities for the duration of the

project).

The Project Specification shall define the area available to the Contractor for use during the

construction of the works. A detailed sketch may be required to adequately define the

Working Area or it may be shown on the Drawings. In either case, the Contractor should be

referred to the Drawings or to an Appendix to the project specification.

T16.5.6 Access to Site

The provisions of site access are generally covered in Standard Specification G1 General

Provisions Clause G1.2.2.

Specific details should be included if there are any special restrictions that may apply to the

method, timing and/or locations of access to the site, available to the Contractor during the

construction of the works. A sketch may be required for this purpose. This sketch should be

included as an appendix to the Project Specification.

A statement including whether the Contractor is responsible for maintaining any access roads

outside the Limits of the Work during the project should also be included.

T16.5.7 Possession of Site

Specific details are required whenever there are limits or conditions, beyond that which are

articulated in the General Conditions of Contract (ref Cl 27 AS2124 and AS4300), giving the

Contractor possession of all or part of the site e.g. part of a site for a bridge viaduct may not

be available until a building on it is demolished by others.

Any such limits or conditions must be carefully considered and must be clearly specified. All

deviations from the General Conditions of Contract are to be approved by DIER.

T16.5.8 Separable Parts of the Works

If a part or parts of the works are required to be completed and handed over prior to the

completion of the whole of the Works, details defining the separable part(s) are to be provided.

T16.5.9 Concurrent Work

Detail of any other Work which is being carried out either within or adjacent to the work site,

by either the Principal, Utility Authorities or other Contractors are to be provided.

This is particularly important where major utility relocations have been arranged to be

undertaken by either the Utility Authority or its agent.

materials. The clause should also identify when the Contractor becomes responsible for care

of the materials.

The Project Specification shall define how material supplied by the Principal complies fully with

DIER’s Standard Specifications and evidence of such compliance.

“as constructed” levels, compaction and moisture content on earthworks produced on a

previous project.

T16.5.12 Superintendent’s Facilities

The requirements for the provision of the Superintendent’s facilities are described in Standard
