    Methane extraction system

    Does anyone have any tips or references for design of a methane collection system below the ground floor of a building (built on organic fill). I know we have install perforated pipes to mechanically vent the sub-floor, but that's about it. Thanks in advance.

    Laterally tied pilecaps

    Consider a large building separated into different components with expansion joints. The structure is supported on short piles, tied together laterally (situated in a seismic zone). Should the pilecaps be tied together across (below) the expansion joints, or not? Thanks for your thoughts...

    Water-retaining structures

    What is the North American (US +/or Canadian) code of practice for designing water-retaining concrete structures? I have ACI 350, but it doesn't go into as much detail on crack control and serviceability requirements as I expected. Can someone steer me in the right direction? Thanks.
