Pre-Cast Parking Structure Cost Data

[JoelTXCive]

I need to put together a preliminary cost estimate for a pre-cast parking structure.

Does anyone know of any good resources where I can find cost data?

We have been asked to provide a conceptual layout and some preliminary cost data so that our client (governmental agency) can allocate money next year.

The proposed parking structure would be:

[ul]
[li]Single story (see image below)[/li]
[li]Approximately 250' x 157' = 39,250 sq. ft.[/li]
[li]Constructed in South Texas and in a salty environment (~200ft from the beach)[/li]
[/ul]

Thank you in advance!

WGI puts our a publication each year based on a precast garage baseline. It might be useful:

Otherwise local precasters may be able to offer some useful numbers.

I unfortunately don't have the reference you're after, however we just had an in-house PD session about pre-cast parkades. Our environment is punishing for different reasons (central prairies of Canada). The life-cycle costs of precast parkades compared with cast-in-place are essentially equal if the proper amount of maintenance is being done. We are part of projects doing repair/maintenance on pre-cast parkades and the volume of joint sealant replacements would boggle your mind. It's miles of joints in a parkade that require annual review and semi-regular replacement.

So I guess what I'm saying is, ensure to advise your client on the maintenance costs of a pre-cast parkade versus cast-in-place. There are tons of pre-cast parkades, the capital cost compared to cast-in-place is a no brainer, I get it. But lifecycle costing may be important to the client.

No, but if well designed, you should have about 130 parking stalls, each level...

Best way would be to talk to the local precaster's that will bid it. See if they can give you a sf cost, etc. At least that way you wont be surprised when you find out you are way off.
