Development Permit Survey
A Development Permit Survey (DP Survey) is usually the first survey required at the start of an infill development project. A DP Survey contains information crucial to the architect for determing the layout of the subject lot, adjacent lots, and surrounding area. Information shown on the DP includes: building dimensions, setbacks and sideyards, block plans, streetscapes, elevation views, geodetic elevations, overhead and underground utilities, and other relevant information required by the approving authority.
Stakeout
A Stakeout survey can be requested based on an approved Plot Plan and building grade form. It is to be performed before any excavation. A survey stake and a spike are placed at an offset from the true house corners. The offset measurements are made from the spike, and the offset distance to the corner, as well as a cut elevation to the bottom of the footing are written on the stake. A Stakeout survey is important to ensure that the construction will be built according to the design.
Pinning
Pinning is a survey used to precisely mark the locations of the foundation walls. It is usally done after the excavation, before the footing is poured. After the survey is complete the cribbers will know exactly where the house corners are. Without this information you face the risk of the house not being in the correct position, which could result in very expense problems.
Elevation Check
A main floor elevation check is required by the City of Calgary for all infill developments within city limits. This check is required to ensure that the actual foundation elevation matches the approved elevation on your Development Permit. A roof peak elevation check is another mandatory check required by the City of Calgary. It is required to ensure that the house has been built in accordance with the approved Development Permit, and to ensure that the house does not exceed the City of Calgary’s maximum allowable height restrictions. A footing elevation check is recommended to confirm that the Actual Top of Footing (ATF) will be built according to design elevation.
Real Property Report (RPR)
A Real Property Report (RPR) is required by the local municipality to ensure that the property will meet the local Land Use Bylaw. Improvements to be shown on an RPR are outlined in Part D, Section 8.5 of the Manual of Standard Practice, which can be found at: www.alsa.ab.ca.
Grade Certificate
A Grade Certificate is to be used to ensure that the property will meet the local Lot Grading Bylaw. This will help to make sure that water will drain away from the property, thus minimizing the possibility of foundation problems due to water drainage.
Engineering Services
We can provide engineer reviews for building permit purposes such as foundation wall, tall framed wall, and Form A. We can also provide engineering services during the construction process such as soil bearing certificate, and sulphate letter. Engineer reviews, as per request by the safety code officer for professional involvements, are also available.
