I would wager the problems that Westrich’s projects have faced have been more on the construction management side verses design side. It’s so based upon relationships between your project team and your subs/suppliers. There are going to be a lot of growing pains in this regard with a newer company, but also as cost overruns inevitably begin to occur, it becomes more opportune to lowball/cheapen out with your materials and subs, creating substandard product.
There is a reason only a select few developers here do construction management in-house despite the cost.
