GENERAL INFORMATION
Invitation
Lethbridge County, (hereafter referred to as “The County” or “County”), is requesting proposals from qualified contractors to crush and stockpile 300,000 tonnes of aggregate at the Rakus South Pit, located at SE 23-12-20-W4M, adjacent to Highway 845. The work may commence following the contract award and must be completed no later than February 26, 2026.
Project Background
This project is a key part of the County’s ongoing efforts to ensure the timely and cost-effective delivery of infrastructure and maintenance initiatives. The aggregate produced through this contract will directly support various County-led projects, including road gravelling, road construction, and other public works undertakings throughout the County.
The County intends to produce a total of 300,000 tonnes of crushed aggregate, to be processed and stockpiled on site. The selected contractor will be expected to mobilize equipment and commence operations following the contract award. The crushing and stockpiling work must be completed no later than February 26, 2026, to align with the County’s 2026 seasonal planning and operational needs.
Through this RFP, the County aims to secure a contractor who can deliver high-quality material production services with a strong emphasis on efficiency, reliability, and adherence to safety and environmental standards.
Scope of Services
All work shall be carried out in accordance with the Alberta Transportation Standard Specifications for Highway Construction, Edition 16-2019, Section 3.2 – Aggregate Production and Stockpiling, specifically for Designation 4 Class 25 Gravel Surfacing Aggregate. For the purposes of this contract:
• “Alberta Transportation” shall be interpreted as Lethbridge County, and
• “Engineer” or “Consultant” shall mean the Manager of Technical Services or designate.
Material Requirements
Aggregate must consist of hard, sound, durable particles of sand, gravel, and rock, and must be free from:
• Elongated or flaky particles
• Soft shales
• Clay lumps
• Organic material or other deleterious substances
• Material must comply with Table 3.2.3.1 of the specification and be adjusted or modified by the Contractor as necessary to meet these standards.
Testing and Quality Control
In all sources, quality control is the responsibility of the Contractor, and all testing must conform to Alberta Transportation Standard Specifications for Highway Construction, Edition 16-2019, Section 3.2 – Aggregate Production and Stockpiling, 3.2.3.2 Quality Control.
The Contractor shall use Professional Engineering services and a qualified testing laboratory licensed to practice in the Province of Alberta to assess and where necessary, modify the aggregate materials being produced to ensure their end use meets all specification requirements. The
Contractor shall provide and maintain equipment and qualified personnel to perform all field testing necessary to determine and monitor the characteristics of the materials produced
A certificate of analysis shall be provided for every 3,000 tonnes of aggregate produced, or once daily, whichever is more frequent.
Lethbridge County may inspect the aggregate production process and test and monitor the quality of the material being produced by the Contractor at any time and as often as he deems necessary. Such inspection or testing shall not in any way relieve the Contractor of the responsibility for producing aggregates that meet the Specifications in all respects.
Payment
Selected Proponent will be compensated for their services on a monthly basis, or upon completion of the project.
The Proponent will determine the payable quantity by measuring the material containing the aggregate that has been incorporated into the accepted work. If a discrepancy in quantity amounts exists, a third party will be hired by the County for further verification.
When required, a conversion factor of 1 m³ = 1.632 tonne will be used.
In alignment with Alberta Transportation Standard Specifications for Highway Construction, Edition 16-2019, Section 3.2 – Aggregate Production and Stockpiling, 3.2.4.3 Surplus Crushing Aggregates, no payment will be made for the following: material rejected by the County or that does not meet applicable specifications; the natural fines portion of a split aggregate; rejected fines; and reject oversize aggregate
