List, I have a existing foundation system that was a pile and grade beam with irregular grid system. 1960's vintage. Demolition consisted of removing tops of pedestals. The foundation system supported heavy equipment structures in a local refinery. I am looking for do's and don'ts on encapsulating the grid with about 9" of concrete above and below the existing grade beam surfaces and reinforce heavily. We are at about a 30' x 50' footprint. My concerns are with the difference in shrinkage and what to assume. Should I look at the cap as a monolith and take credit for the existing grade beams or look at it as some sort of new grid, old grid and dowel into old? The new loads are lighter than old but nothing lines up column or cg wise. I am thinking just rough up the surfaces and use a bonding agent to glue it all together. Bottom of beams will be a bear. Need some really short or folding persons for that I guess. Thanks for opinions. Robert M. Hanson, S.E. Kappa Engineers Carson, CA.
