Parking Garage Question
Parking Garage Question
(OP)
To all;
I am looking for some guidance on weather I am just being hard headed. I am presently working on a medical center that will have a parking area under the building but will be kept to existing elevations. In other words the building will be raised and parking will be underneath. I have been going around and around with the architect and his designer about drainage for the parking area under the building. His designer wanted me to have the driveway coming into and through the parking raised with parking spaces sloped down from the drive. The curbing would have curb cuts and allow water to migrate away from the parking spaces but there is still risk of collection in the wrong places. This also in turn has the slope towards the foundation footings as well as the possibility of collecting at the building entrances. Our structural said he would not seal it the way they want it and told me to just put my foot down about it.
I informed the architect in a meeting yesterday that I would prefer having the slope of the parking go to a channeled center of the drive and convey the incidental water away from the area. This would allow flow from cars, rain that blows into the area and possible sheet flow from collecting in all the wrong places. I told them that I felt parking garages, especially with this design, should be sloped at least 1.0 to 1.5% to the catch basins. I felt like I was in the right but we basically left the meeting agreeing to disagree. I also said without being too direct that if they did not like it then they should possibly seek another engineer.
With what minimal information I have given you, do you think I am in the wrong?
Thanks in advance.

Did the strucural speak out to the architect, or just go through you? If just to you, the strucural and the geotech should also provide thier opinions to the architect.

As long as you can get positive drainage from the front or to the drive isle, this should not be an issue. There should be no areas where water can accumulate. A minimum slope of 1-1/2% (1% in my opinion is not enough for drainage or to reduce areas where an ice hazard can form) should be maintained. In addition, your engineer should stipulate whatever sealing process should be used as well as how often this should be repeated. Should take special care at any expansion joints (good ones are costly). In additon, a schedule for hosing down the parkade should be established and hose bibs should be installed within the parkade.

Hope I'm on track and not missing something.

Now when you are in the same position, you can back your argument with the city has rejected that design in the past.
