Since its open­ing in 1957, the National Theatre in Man­nheim has not under­gone any major refur­bish­ment. There­fore, in 2015 the city of Man­nheim has decided to carry out a gen­eral renov­a­tion for the listed build­ing. An inter­dis­cip­lin­ary plan­ning team was incre­ment­ally com­mis­sioned with the design of the plan­ning phase one, two and three of the Offi­cial Scale of Fees for Ser­vices by Archi­tects and Engin­eers (HOAI). In the begin­ning of August 2017 the client received the res­ults of the pre­lim­in­ary design (phase two).

PRO­PRO­JEKT was assigned by the pro­ject office to check the pre­lim­in­ary design for plaus­ib­il­ity and accord­ance with the pro­ject object­ives. The main aspects of the eval­u­ation included a review of the require­ments of the HOAI, a check of the imple­ment­a­tion of the cli­ent’s spe­cific­a­tions – espe­cially regard­ing stage tech­no­logy – as well as a veri­fic­a­tion of the cost estim­ate. The eval­u­ation res­ults and the derived recom­mend­a­tions for action were delivered on sched­ule to the pro­ject office at the end of Septem­ber.

• Com­par­ison of the sub­mit­ted pre­lim­in­ary design with the require­ments of the HOAI phase two, to check whether the tasks have been fully com­pleted
• Review of the imple­ment­a­tion of the cli­ent’s spe­cific­a­tions (user require­ments)
• Plaus­ib­il­ity check of the plan­ning, in par­tic­u­lar the stage tech­no­logy as a cent­ral ele­ment, espe­cially regard­ing the func­tion­al­ity of the venues as well as with respect to the costs
• Plaus­ib­il­ity check of the cost estim­ates
• Sum­mary of res­ults and recom­mend­a­tions for action
