Details of Typical Exterior Masonry Conditions are a good practice. In some simple projects they may not be required. However, by detailing the conditions, you create a basis for requiring the level of detail that the project should receive. 

These details are suggested to specify any special configuration, construction and materials required for the conditions required at openings and joints in masonry construction.

The lintel schedule makes sure that someone is responsible for lintels at openings. The joint details address the fundamental condition that concrete block shrinks over time and brick expands over time. This minor movement can create major problems if not addressed during construction.

Roof Expansion Joints are customary where a new roof abuts an existing building, as in this case, where there is an expansion joint in the building, or where there is a change in plane of the roof. In this last instance an expansion joint is not always required.
Roof Expansion Joints prevent movement from damaging the roof. Movement is almost always the root cause of roof problems. After eliminating chemical incompatibility and physical damage causes, you are left with movement due to gravity, thermal expansion/contraction (of membrane or building), or shrinkage of membrane. 
Some roof membrane types are more susceptible to movement than others. If your project expects a life of more than 40 years, it is prudent to expect that the membrane type will change when re-roofing takes place at some point. 
In the roofing condition shown here, the new building had an EIFS finish that we did not want to flash to, so we tucked the counter-flashing under the EIFS. This tactic could be used to flash into an existing unsuitable surface, too.
