Type of survey

The complexity of the survey, which could range from merely finding a property line for a fence to constructing a commercial building or subdivision.

Research

In some cases, the land in question may have been surveyed by multiple parties in the past. Conducting a complete search of all plans, field notes, and charges on title can be time-consuming.

Size and shape of property

An irregularly shaped parcel will have more corners and a longer boundary than a regularly shaped parcel of the same area.

Terrain

A level parcel of land is easier to survey than a steep one. Properties located along a river or stream may also complicate the survey.

Vegetation

The Land Surveyor may need to trim branches, brush, and trees to create clear paths and line of sight.

Accessibility

The time needed to complete the survey depends on the distance to the site and the level of difficulty involved in reaching all the corners. In some cases, walking may be the only way to access a corner. This can be further complicated by uncooperative neighbours where the only way to get to a corner is through their land.

Amount of existing evidence on the property

Past monumentation such as iron posts, pipe posts, bearing trees, etc., can be helpful to the surveyor. Their absence may make it difficult to retrace the original survey.

Time of year

Foliage can present a problem in the summer, while winter weather can slow travel and conceal field evidence.
