The residential property owner has, for years now, been taken for a ride. The construction jobs ordered pushed them into a catch-22 situation. They had no alternative but to order them. After all, these were not jobs they could do by themselves. And they had no alternative but to pay the exorbitant price quoted, because the feeling was, who else can do this work. And even if they were able to get an alternative quote that was characterized as being dirty cheap, they would be pushed into a corner in not knowing how to challenge the shoddy workmanship by way of drawing up a complaints sheet.
Commercial property owners are, of course, a lot more astute. Eyes on the ball, they are also a lot more cautious. They have to be because their business is always the bottom line. If no revenues are secured from reliable tenancies, no business sustainability can be maintained and no profits can be realized for the owners and/or their shareholders or interested parties. They also need this steady revenue stream in order to ensure that they are properly able to manage their property stock. And of course, they also need to have a healthy capital expenses budget in place in order to cater for the expense of qualified construction work, no matter what its specificity.
A retainer fee may well be set aside for regular construction consulting services. These are the agencies that are able to advise their clients accordingly. They can cross-reference pricing mechanisms so as to ensure that the commercial clients they represent are not being overcharged. Depending on the scale of the domestic product, this is a service that could and maybe even, should be used by residential property owners as well.
