Joel: As I study sheet 10 in detail, I can see the importance of the final elevations of the vault as it relates to the paver and sidewalk elevations. I have already directed John Burn to place as per sheet 10, however it may be best to hold off adjusting the top until all grade work and street paving is in place. I think the best course of action would be to adjust the top only by placing shims and grouting the top from below. Do you concur? Robert Farrow Chief Operating Officer CPS Civil LLC
