DRFA Program - HSC25B - North East Unsealed - Reconstruction Works

Overview Hinchinbrook Shire Council invites tenders from suitably qualified tenderers for reconstruction works required due to the impacts of TC Jasper and the North and Far North Tropical Low, which occurred between 29 January and 28 February 2025. About The treatment guide referenced in this tender was prepared by the Queensland Reconstruction Authority (QRA) and provides a common set of treatments for the scoping of road reconstruction works following damage caused by natural disasters. The treatment list represents the most commonly used treatments across the state, with detail provided for each treatment to enable consistency of language and a common understanding of treatment inclusions and exclusions. A consistent treatment set also supports consistency in the methodology for benchmarking local rates. The guide is reviewed from time to time to ensure emerging or common treatments are documented. Scope The works are described in more detail in Part 5 of the tender documentation. The scope is based on the following treatment categories: Unsealed pavements Treatment selection for the restoration of unsealed roads should be commensurate with the classification of the asset and its maintained condition prior to the disaster. Unsealed road assets are generally classified as either unformed, formed, or gravelled. Sealed pavement repairs Treatment selection for the restoration of sealed pavements should be appropriate to the road type, functionality, pre-disaster condition, and value for money outcomes with reference to site specific constraints. Sealed pavement repair treatments include: Site establishment and disestablishment of all plant, labour and materials Establishment and disestablishment of traffic control Determination of work area Removal and re-instatement of roadside furniture (such as guide posts and signs) as required Clean up of the site and disposal of any waste or removed material in accordance with applicable State Government legislation or Local Government by-laws Clearing and earthworks Clearing and earthworks treatments include: Site establishment and disestablishment of all plant, labour and materials Establishment and disestablishment of traffic control Determination of work area Clean up of the site and disposal of any waste or removed material in accordance with applicable State Government legislation or Local Government by-laws Concrete works Damage to concrete may include scouring, undermining, structural cracking, or total loss as a result of large or intense rainfall events. Concrete works treatments include: Site establishment and disestablishment of all plant, labour and materials Establishment and disestablishment of traffic control Determination of work area Clean up of the site and disposal of any waste or removed material in accordance with applicable State Government legislation or Local Government by-laws Drainage structures Damage to drainage structures, including scouring, undermining, debris impact, separation of units, silting, or total loss, can occur during large or intense rainfall events. Drainage structure treatments include: Site establishment and disestablishment of all plant, labour and materials Establishment and disestablishment of traffic control Determination of work area Removal and re-instatement of roadside furniture (such as guide posts and signs) as required Clean up of the site and disposal of any waste or removed material in accordance with applicable State Government legislation or Local Government by-laws Protection works Damage to rock protection (including mass or dumped rock, rock pitching, and rock mattress) can occur as a result of high velocity flows, undermining, or debris impact during large or intense rainfall events. Subject to the ability to achieve value for money, damaged protection works should be restored commensurate with pre-disaster arrangements. Where reconstruction to pre-disaster arrangements is uneconomical due to material or labour availability, or not feasible due to obsolete construction techniques, contemporary techniques may be employed. Protection works treatments include: Site establishment and disestablishment of all plant, labour and materials Establishment and disestablishment of traffic control Determination of work area Removal and re-instatement of roadside furniture (such as guide posts and signs) as required Preparation of work area Placement of geotextile where required Construction or placing of protection works Clean up of the site and disposal of any waste or removed material in accordance with applicable State Government legislation or Local Government by-laws Road furniture and delineation Road furniture is often damaged during natural disasters as a result of flood waters or debris impacts. Where damage has occurred to road furniture, the number of units replaced should be commensurate with the pre-disaster arrangements, however a current standard of the pre-disaster system or item should be used. Road furniture works include: Site establishment and disestablishment of all plant, labour and materials Establishment and disestablishment of traffic control Determination of work area Removal of damaged road furniture Re-instatement of roadside furniture Clean up of the site and disposal of any waste or removed material in accordance with applicable State Government legislation or Local Government by-laws Following restoration of sealed pavements, line-marking is generally required and should be consistent with either the adjoining sections of road or the pre-disaster arrangement. Reinstatement of line-marking includes: Establishment and disestablishment of traffic control Determination of work area Cleaning the pavement in the work area as required Spotting and symbolising Application of marking material
