My house is 98 years old in denver. The two story exterior walls,and the foundation, are three layers of brick. I was tearing out some paneling in the basement that was nailed to the foundation and found a hole in the foundation wall about three feet wide by four feet. I’m guessing that there was a water infiltration at some point because some of the brickand mortar joints have deteriorated so that they crumble when touched. I have an engineer report that suggests to put a layer of cement over the brick to reinforce the foundation. But in a few places the brick needs to be replaced. How do I replace parts of the brick foundation without upsetting the brick walls above it?

A skilled brickmason can do this.
I'm a little skeptical of putting a layer of cement over the brick -- the adhesion between the two would never be good.

Are there any house movers/lifters in the Denver area? You may want to consider lifting the house or supporting it one side at a time and consider replacement of the foundation with new footings and block/poured/ICF walls (expensive proposition). 98 year old three layer brick with sections missing doesn't sound all that safe. I really don't think that a parge coat of mortar or cement would help an already deteriorating foundation. It would only be a temporary solution to an existing problem ( band aids over bullet holes). I would take a closer look at the rest of the foundation and then determine what your alternatives may be.
If you decide that the foundation is salvageable, Have a mason contractor replace the missing sections and you may be able to tuckpoint the rest of the foundation. I would check the outside for places that water may be getting in and correct those as well.

YDNNF house movers. Any competent mason can jack up or at least support the area a little with bottle jacks. But I kind of doubt that it would even be needed for such a small area.
The old farmhouse my parents bought had a creekstone foundation that was falling apart. They hired a black gentleman of about 60 years named Mr Yerby to come and fix it. He went around the foundation replacing about 10 feet at a time, using a couple of bottle jacks to lift the house when needed.
YDNNF?? You do not need freakin...??
I worked on a place that had old brick walls. The engineer's solution was to drill and epoxy steel rods into the brick, on a grid of about 12", tie a mat of rebar to those rods, and shotcrete the whole thing about 8 inches thick. The guys that did it brought in a large towable compressor and made the whole thing happen snap snap.
If you want to own the house over the long run, deal with the foundation in a meaningful way. The engineer who suggested parging it is out of his mind.
The place we had there, Highlands neighborhood, was similar. Underground stream going through such that we had a serious drain tile/sump system going. The mortar was extremely crumbly and the brich wasn't much more solid. Our solution was a For Sale sign. Good luck.
Oh, building's still standing, last I heard. Get the brick back in and try not to worry. I also see minimal merit in that cement coating.
