This will be our first commercial installation. we have almost everything narrowed down except for the installation of the sod. Plan was originally quoted by design firm to have 660 sq yards of sod installed. I have done my best to figure total area and get around double from the plan which show areas to be sodded. Can someone with more experience with estimating accurately give me a better idea of the size of this job. This help would be greatly appreciated and valued. Thank you for your guy's time in advance.
