Conjugating Conduire/Construire in the indicatif

No mention is made in the lesson for verbs ending in uire (conduits, traduire, construire) that when conjugating the verb construire, the first R is dropped in nous constuisons and vous constuisez. Is it also dropped in ils/elles constuisent or does it stay as in construisent? Does this also apply for détruire?

Paula, 

you may have seen a flawed conjugation table ?

There is no dropping of the first r in any conjugation form or tense of ‘ construire ‘ that I can find. 

The radical ( stem/root ) is always ‘ construi - ‘, with terminal ‘ -re ‘ being dropped across all its conjugated forms. 

Détruire follows the same principle in that its root is also formed by dropping the terminal ‘ -re ‘, giving ‘ détrui- ‘ across all its conjugated forms. 

( As do almost all irregular ‘ -re ‘ verbs as noted by Laura Lawless in the links below )
