the masonry foundations need to leave dowels for the wall above. I think we engineers usually dont tell the locations of the joints in the wall. and the blocks at joints are little bit longer than normal blocks, am i right? then how do we locate the dowel locations accurately if we dont know the joints locations? thanks

GC must coordinate with his masonry sub. If not, then he is going to wind up cutting alot of block and probably will receive a backcharge from his sub.

Just specifying units meeting the requirements of ASTM C90 has no bearing on the shape of the units. There are at least 3 different "non-priority" block configurations used for basement construction:
1. An "H" shaped unit with no molded core, but has 2 half cores and one center web that forms a core space when the block are laid. The webs in the wall are 16" on center when laid. This is used for fully grouted walls. - Readily available in the western U.S. and in selected eastern areas.
2. A double "H" shaped unit that has one molded core and two half cores that form additional cores when laid. This is a true modular cored unit with webs at 8" on center when in the wall. The perfect web and core alighnment maximizes the strength and permits individual cells to be grouted as necessary. It can be used for fully grouted or partially grouted construction. It is also used for walls where the cores are filled with insulation. - Available through progressive U.S. and international manufacturers.
3. A tradtional unit with 2 molded cores, with or without partial end cores. The webs do not align perfectly, but are adequate for partial grouting in most cases. If the first dowel is located properly and reinforcement is in increments of 16" on center, there is no problem with a conflict between the dowels and the block webs.
There are also some other units that are rarely used such as an "H" block with an offset center web, or single core units consisting of a large center core with smooth ends. - Limited availablity.
