Low Strain Integrity Testing of Concrete Piles |  Montreal, Quebec | July 2018

FPrimeC Solutions was engaged by SNC-Lavalin to conduct non-destructive evaluation (NDE) to examine the condition of slender piles on a construction site in Montreal, Quebec.

The Problem

Slender piles need to be evaluated before further construction. The main objective of the NDT/NDE was quality control of the existing condition of piles, and identifying potential subsurface defects.

NDT/NDE Inspection

FPrimeC conducted Pile Integrity Test using i.Pile to evaluate pile continuity, integrity, and consistency.

Coleman Mine |  Levack, Ontario | May 2018

FPrimeC Solutions was engaged by Komri Engineering and Quatro Industries Ltd to conduct non-destructive evaluation (NDE) on concrete shafts supporting the hoist (for transportation to the mine) and other mechanical equipment at Coleman Mine near Levack, Ontario.

The Problem

Cracking was observed on exterior and interior walls. The main objective of the NDT/NDE was to evaluate the existing condition of concrete cracks, crack depth, and identifying potential subsurface defects.

NDT/NDE Inspection

Following a comprehensive Visual Inspection to identify visible cracks on concrete surface, FPrimeC conducted crack depth evaluation and concrete quality using Ultrasonic Pulse Velocity (UPV) method, and Rebound Hammer (Schmidt hammer) to evaluate the mechanical stiffness.

Parking Garage in Residential Condominium |  Thornhill, Ontario | Mar 2018

FPrimeC Solutions was engaged by condominium owner to conduct non-destructive testing on the 46,000 sq ft. concrete slab (2 level parking structure).

The Problem
The main objective of this investigation was to evaluate the condition of concrete slab underneath mastic, identify potential corrosion, and delamination underneath the mastic.

NDT/NDE Inspection
Following a comprehensive Visual Inspection of the slabs, walls, columns, and beams, a combination of Ground Penetrating Radar, Ultrasonic Pulse Velocity, and Ultrasonic Pulse Echo were used to study the slab for possible delamination. Half-Cell corrosion potential test was conducted on slabs, walls and beams to understand the corrosion activity. Concrete cores were taken from the slabs to evaluate the strength, chloride content and carbonation.

Michels Canada Co.  | York Region, Markham | Jan 2018

FPrimeC Solutions was engaged by Michels Canada Co to evaluate the concrete lining thickness along 250 ft. major sever in Markham, ON. The area under investigation was part of 16th Av. Markham Sewer rehabilitation.

The Problem
The main objective of this investigation was to evaluate the thickness of concrete lining in the trunk sewer. The client was also interested to predict the strength of concrete at 30 ft long area inside the trunk sewer. Combination of NDT methods were used to help the client.

NDT/NDE Inspection
FPrimeC conducted a detail Visual Inspection on the concrete lining. The evaluation was followed by Ultrasonic Pulse Echo (UPE), Ultrasonic Pulse Velocity (UPV), and Rebound Number (Schmidt hammer) to evaluate the strength of concrete.

McConnell Lake's Dam | Quebec-Ontario Border | Jun 2017

FPrimeC Solutions collaborated with Ontario Power Generation Inspection and Reactor Innovation (OPG-IRI) to conduct Non-Destructive Evaluation on concrete deck slab at the McConnell Lake's dam. 

The Problem
Cracking and delamination was observed on the concrete slab. The main objective of this investigation was to evaluate the effectiveness of NDT methods in condition assessment of concrete slabs. The client was interested to evaluate the condition of cracking, and concrete quality and strength over the deck slab

NDT/NDE Inspection
FPrimeC conducted a detail Visual Inspection to identify visible cracks on concrete surface. The evaluation was followed by Ultrasonic Pulse Velocity (UPV), and Rebound Hammer to study the current state of the cracks, and the effect on the performance of the foundation.

Portlands Energy Centre | Toronto, ON | Apr 2017

FPrimeC Solutions was engaged by Portlands Energy Centre to perform Non-Destructive Evaluation and Testing (NDE/NDT) of concrete foundation supporting massive gas turbine generators in the PEC generating station in downtown Toronto, Ontario.

The Problem
Cracking and delamination was observed on the concrete foundation of a gas turbine generator, during the routine inspection. The concrete structure sits over a mat concrete foundation and supports the generator. The client was interested to evaluate the condition of cracking, and the effects on structural performance of the foundation.

NDT/NDE Inspection
FPrimeC conducted a detail Visual Inspection to identify visible cracks on concrete surface. The evaluation was followed by Ultrasonic Pulse Velocity (UPV), and Rebound Hammer to study the current state of the cracks, and the effect on the performance of the foundation.

Darlington Refurbishment | Bowmanville, ON | Feb 2017

FPrimeC Solutions was engaged by SNC-Lavalin Nuclear  and Aecon Industrial to evaluate the quality and strength of concrete over 400 m2 concrete deck slab using non-destructive testing techniques and with minimum intervention. The structure was part of Darlington Refurbishment project by Ontario Power Generation (OPG) at the Darlington generating facilities. 

The Problem
The client was concerned about the quality and strength of a recently poured concrete that was subject to cold weather condition. The client required that the investigation be limited to non-destructive evaluation, with minimum number of coring, and identify potential weak points over the deck slab.

The Solution
After careful review of existing data, FPrimeC designed a NDT/NDE plan for evaluation of concrete strength on the 6" concrete deck slab. The plan combined a series of NDT solutions, including Ultrasonic Pulse Velocity (UPV), and Rebound Hammer in order to identify potential weak points, and predict the compressive strength of concrete. Strength maps representing the compressive strength of concrete were developed to help the client with locating areas that required strengthening.

Andrews Engineer | Ottawa, ON | Nov 2017

FPrimeC Solutions was engaged by Andrews Engineer to perform non-destructive evaluation of concrete at the Ottawa-West Nepean Collector (City of Ottawa). The main goal of the project was to assess the quality of concrete in the trunk sewer, and evaluate the thickness of concrete lining in 400 long trunk sewer. 

Our NDT/NDE Solution

Based on the existing condition of the trunk sewer, and after review of the exposure, FPrimeC proposed the use of Ultrasonic Pulse Velocity (UPV), Ultrasonic Pulse Echo (UPE), and Surface Electrical Resistivity (ER) to evaluate the quality along the trunk sewer. The test plan was designed such that the test equipment could be easily mobilized in the confined space. Test locations were identified and the test surface was prepared.
