Culvert design

HILCON will conduct an in-depth review of the site and surrounding variables to determine peak flows and high water levels. Culvert size and shape will be determined based on site specific characteristics such as fill height, watercourse, slope, fish passage and bedload. HILCON's project experience include new culvert design, structure rehabilitation, inspection, load rating and removal. HILCON can inspect aging culverts and recommend prudent courses of action as required.

Stormwater Modelling

HILCON’s Hydraulic team has experience building storm water models to estimate peak flows and extreme water levels. Minor systems, major systems, stormwater storage and tidal scenarios can be analyzed in a variety of hydraulic/hydrologic models. HILCON's model experience include HEC-RAS, PCSWMM, EPANET and others.

Subdivision Design

Proper hydrologic design for a subdivision is critical to the development process. HILCON works closely with land developers to create an efficient site-specific storm water management plan. HILCON's engineers create innovative solutions that meet the needs of the site while respecting the provincial or municipal regulatory standards.


HILCON works hard to minimize impacts on waterways and protected areas while keeping projects on time and on budget. HILCON's project management team can procure all necessary environmental permits, saving the clients time and money and ensuring projects proceed smoothly from planning through to completion.

Seawall (Revetment) Design

Storm surges can be devastating to coastal areas however proper seawall design can mitigate the damage. HILCON has the knowledge and experience to engineer innovative solutions to withstand the power of the ocean.
The team begin with a detailed survey and tidal analysis of the area, and then chooses materials that will fit the budget and technical specifications of the job.
HILCON’s seawalls are designed to withstand tidal erosion, flooding, ice and wave action.

Project Management

HILCON has an exceptional team of talented project managers that can take your project from planning to completion and seamlessly manage every step in-between.
The professional project management service provides effective coordination of all project components to keep everything on time and on budget. HILCON understands how to keep projects running smoothly by working closely with the project team and stakeholders.


HILCON uses a phased approach that refines quantity estimates as detail design progresses. Accurate quantities provide sound estimates critical to the budgeting process. The advanced estimate calculations provide accurate figures for the quantity of materials needed for each job. This process is designed to safeguard your budget, while ensuring the job is completed to the rigorous standards of quality HILCON is known for.


A sound estimate is critical to planning and budgeting for a project. HILCON uses a phased approach that refines the estimate as detail design progresses. The team's experience estimating various infrastructure projects allow them to assist the clients with budgeting for a project from the early planning stages to construction. HILCON understand budgetary restrictions and will provide options and solutions to help make any project a success.


A critical part of quality assurance is full-time construction inspection. HILCON offers this service to its clients ensuring that the construction is completed in accordance with the project specifications. In addition to construction inspections, HILCON’s experienced staff performs condition inspections of various types of infrastructure such as bridges, buildings and culverts.
