Surveying Project Highlights in Brantford, Hamilton and Cambridge

Project highlights

No two surveying projects are exactly alike. One week may involve an advanced bridge construction project beside a river. Another may mean carefully documenting the existing conditions of a developed site surrounded by buildings, trees and landscaping. The next may mean setting out a building foundation inside a wet excavation, where site conditions are far from ideal.

These are three recent examples of the surveying work completed by Geo Vision Surveying Inc across Brantford, Hamilton and Cambridge, Ontario. Each project presented a different challenge, but they shared one requirement: the construction and design teams needed dependable field information they could use with confidence.

Construction surveying on a Brantford bridge project

One of our recent Brantford assignments involved continued construction surveying on a bridge project that has now reached an advanced stage.

Construction surveying is not limited to setting a few points before construction begins. As a structure progresses, additional measurements, layout and verification may be needed to support later stages of work.

On a bridge project, the relationship between the design and the constructed structure is especially important. Structural components installed later in the project may depend on the position and elevation of work completed earlier.

Using Trimble surveying equipment, Geo Vision Surveying Inc provided field support to help the construction team keep progressing with reliable positioning information.

There is also a particularly rewarding side to this type of work. Surveyors often become involved when a project exists mainly as engineering drawings, coordinates and layout points. Returning later and seeing those points turned into an actual structure is a clear demonstration of how surveying contributes to construction.

Why construction surveying matters as a project advances

Accurate construction surveying can support a project by helping teams:

• establish required construction positions
• transfer design information to the field
• verify critical elevations and locations
• provide additional layout as construction progresses
• maintain reliable references between different stages of work

The objective is practical: provide clear and dependable information that the contractor can build from.

Topographic surveying on a developed site in Hamilton

Our Hamilton project presented a completely different working environment.

Topographic surveying is often pictured as work on a large, open site. In reality, many projects take place in areas that are already developed.

This Hamilton site included existing buildings, mature trees, landscaping, fences and other features that affected how the fieldwork could be completed.

A topographic survey records the elevations and visible physical features of a site, so that engineers, designers and other project professionals have an accurate representation of the existing conditions.

On a developed site, this can require careful instrument positioning and a systematic approach to make sure important features are captured despite restricted sightlines and access.

Using Trimble surveying equipment, we collected the field information required to document the site conditions and support the next stage of planning.

What can a topographic survey document?

Depending on the requirements of the project, topographic fieldwork may document information such as:

• ground elevations
• changes in slope
• buildings and structures
• walkways and hard surfaces
• vegetation and significant site features
• drainage-related features
• other visible conditions relevant to design

The value of the survey is not simply the number of points collected. The goal is an accurate and useful representation of the site, so the design team can make informed decisions.

Grading survey and building foundation layout in Cambridge

The third project took us to Cambridge for grading survey work and building foundation layout.

This project demonstrated another reality of construction surveying: field conditions do not always cooperate with the schedule.

Following excavation, significant water had accumulated in parts of the site. Some of the foundation layout stakes were positioned in areas surrounded by standing water.

The site conditions made movement and layout more difficult, but the construction team still needed reliable horizontal positions and elevations before proceeding.

Using established survey control and Trimble equipment, the required foundation positions and grading information were transferred to the site.

Why foundation layout is important

Building foundation layout connects the design drawings to the physical excavation. The surveyor establishes the required positions, so the construction team knows where the building elements are meant to be built.

Errors at this stage can affect later work, which is why careful setup, verification and communication are important. A building layout may establish information used for:

• foundation corners
• structural lines
• offsets
• reference points
• elevations
• other construction positions required by the project

Grading information matters too

Horizontal position is only part of the construction picture. Elevation and grading information helps the project team understand how the proposed work relates vertically to the surrounding site.

Accurate grading information can support drainage planning, construction elevations and coordination between the building and the surrounding surfaces.

Different sites require different surveying approaches

These three projects show why surveying is not a one-method service:

• Brantford: the bridge needed construction support on an advanced infrastructure project.
• Hamilton: the topographic survey meant working carefully around an existing developed site.
• Cambridge: foundation layout and grading work had to adapt to a wet excavation.

The instruments provide accurate measurements, but effective surveying also takes field judgment, planning, reliable control and the ability to adjust the working method to the conditions on site.
