Advance Procurement Notice
Heritage Stone Masonry Restoration – Stone Sourcing
CFB Kingston
2017 - 2019

Purpose of this Advance Procurement Notice
This is not a bid solicitation. This is an advance notice of potential projects with anticipated cut stone material requirements. The notice is intended to provide interested stone suppliers information regarding the stone characteristics required for these projects and define the testing required to prove suitability to meet the level of acceptance. Note that there is no guarantee that these projects will proceed.

Description of the Program
CFB Kingston maintains classified and recognized heritage limestone buildings and structures such as perimeter walls. Stone sourcing is critical to the success of the historic masonry restoration projects related to these heritage buildings. Upcoming projects include restoration work at these heritage structures which will require full replacement stone and partial Dutchman style repairs. Stone sizes very based on the Work.

The overall value of stone required for the program is estimated at $1,500,000 with the maximum value of stone required for any individual project estimated at $250,000.

The Future Masonry Restoration Projects include, but are not limited to, the following:
            .1   R33 Fort LaSalle Dormitory Masonry Restoration Phases 2 to 4
            .2   R32 Yeo Hall Masonry Restoration Phases 2 to 4
            .3   R30 Fort Frederick Restoration multiple phases
            .4   Kingston Armouries Restoration
            .5   Naval Dockyard Wall Restoration
            .6   Fort Frontenac Wall Restoration
            .7   R15/R16 Currie Mackenzie Masonry Restoration

Description of the Services
It is intended that Stone suppliers who have met the testing requirements and approved by DCC, may have the opportunity to provide stone to the Contractor(s) undertaking the restoration work.

Stone Quality Requirements
The replacement stone must be geologically identical to the existing stone. By geologically identical, it is meant the “micritic limestone” that comes from the Gaul River Formation of southeast Ontario. Two types are alternately bedded within this formation: those that develop a distinctive white patina (calcium carbonate rich) upon aging and those that develop a distinctly buff coloured patina upon aging. For the purposes of this program supply, the selection must only come from those quarry beds that provide patinas that are distinctively white. Other types of limestone will not be accepted as they will negatively affect with regards aged patina, chemical and structural incompatibility with the existing fabric.

Stone shall be tested and minimum physical requirements for Medium Density Limestone per ASTM C568 shall be met including:

Bulk Specific Gravity > 2160 kg/m3
Water Absorption < 7.5% by weight
Modulus of Rupture > 3.4 MPa
Compressive Strength > 28 MPa
Abrasion Resistance> 10 Ha

Accelerated patina testing shall be carried out to confirm the distinctive whitish grey age colour of calcite rich stone that is a prerequisite for matching the Kingston buildings. Dolomitic stone is not acceptable. The freeze-thaw of 400 cycles shall be carried out to establish resilience.
Quarry shall not use blast on property.

Process
To be approved, stone suppliers must meet the testing and aesthetic requirements above. Stone suppliers must undertake testing at their own cost and must submit testing results to DCC for review prior to being accepted as an approved stone source.
