Naive question: When switching after phase 4, it will probably require some onboarding into the design and other documents, but what exactly has to be done twice?
[ < ] Why is it difficult to get the planner of phase 5 also as the construction management for phase 8?
Phases 4 and 5 are different further developments, each derived from the results of performance phase 3. Acting as a surrogate to develop a performance phase 5 for a construction project in which one was not involved in performance phase 3 is a small biblical punishment.
Many construction-related experts are so specialized in performance phase 8 that they rarely offer performance phase 5 as well. This also makes much less sense than offering the entire second half (performance phases 5 to 8). The latter, in turn, would be a completely different business model than that of a construction-related expert (and would already require a substantially different operational structure). Therefore (consider: I say this as someone who professionally recruits such specialists), you will (not impossible, but) have difficulty finding providers for performance phases 8
and 5. You at least understood that theoretically the same service provider for at least 5 and 8, if not for 3, 5, and 8, would be a blessing. But: will that benefit you? - good luck!
Thanks for the offer, I prefer a planner nearby with personal contact.
I also look for these specialists exclusively near the respective construction site. I could do little with those from my residential area; there I have (intentionally, I also want to be able to go to Aldi unshaven) practically no clients.
The reality here was that for phase 8, we were dealing with 8 out of 11 offices within about 30 km of the construction site, all offered phases 1-4 and a few offered 1-2, but none wanted to do 1-3 ("we do preliminary design and design together"). Everyone advised always including phase 5 as well, even if >70% of clients would not do that. Three of them only do performance phase 5 without sanitary and electrical planning; the respective trades would have to plan those themselves.
Looking for a planner nearby is best. Among the best home architects, "office" is already a big word; they are classic freelancers with a draftsman/construction supervisor assistant and a part-time office worker. A good architect explicitly (though more politely than I do) points out that a mandate scope of performance phases 1 to 4 is the "idiot’s budget package"; the mandate scope "Module A - (dough rest / decision-making) - performance phase 3," on the other hand, is a good choice and, depending on the result of dough rest with decision-making, exactly the right one. Phases 4 and 5 should not be separated, following "st"’s example; and performance phases 5/6/7 are a kind of triad. A performance phase 5 without installation is gross nonsense, practically a "performance phase 5 without performance phase 5" – what is that supposed to be: formwork plans with BD and DD? – that's nonsensical stuff! Architects who stop after obtaining the permit at the urging of the clients are okay—on the other hand, those who on their own initiative offer a mandate scope of phases 1 to 4 are highly " warns" suspicious; from them, one can expect plans running severely over budget.
Oh yes, apologies, I already meant with the tendering.
Performance phase 5 is the essential basis for phases 6 and 7 and serves, as its fee share already implies, far more than just giving the craftsmen their drilling points pre-chewed.
Above all, I consider it highly advisable that you catch up on / have caught up the missed decision-making together with the omitted dough rest. With phase 4 completed and the building permit obtained for a stone house, this makes somewhat less sense than usual, but nevertheless, I would still place it before the second half in your case. But as I said, don’t wait any longer: as soon as my waiting room is processed, I will disappear into vacation (and after that the first appointments will be available again from February). For the other independent construction advisors, the situation is similar, although their vacation times obviously differ.
