I have the opportunity to bid a large condo development install. The project is larger than any that I've done before so I was looking for a little insight from the more experienced! Whenever I have bid install before, I would take all my plants and mark them up to retail, add a delivery charge and then essentially make out a bill for the job using estimates. I would use my "retail" numbers for mulch, compost, etc and then charge my labor rate for the estimated time it would take and then mark the whole bill up a percentage to account for overages in the project. For the size jobs I usually do this serves me well. I have been very accurate to what the jobs actually cost in the end. I'm not sure if this will serve me well on such a large project. Here are the specific issues that I am concerned about... The bid has two parts, first, installing all of the plantings for the common areas and aftercare and secondly, a separate bid for the individual "foundation plantings" rather than one price to do all of them. The units will be built as they are sold, so the landscaping will be done over several seasons. The project manager wants to see a price for plant materials & for labor. I plan to give a price for the plants and then roll all of my other costs - mulch, compost, equipment, labor, etc. - into a second line item. My guess is, they have plans to try to get the plants on their own or attempt to negotiate better pricing. How should I determine my plant pricing? Should I stick with marking up to retail? or utilize another method? My concern is that if they supply the plants, there is a huge chunk of money that I lose out on. I realize that I'm still making money on my labor and other materials but I'm not sure how I feel about losing the profit on the plants. My second concern is on aftercare. The residential plantings that I've done in the past, caring for the plantings after I leave is up to the customer. In this case I would be responsible for keeping the plants watered for a certain period of time. I would be expected to give a 1 year warranty on the plant material (obviously if I don't supply the plants, there is no warranty). How do you generally account for this aftercare? We have fairly timid summers here, so I would not likely need to worry about irrigation during the spring, fall, or much of the summer unless we get a dry spell. There is a pond in the development so I would have ready access to water for irrigation and I am planning to include using TreeGator bags for all of the large trees. There are, however, a number of planting beds spaced throughout the development that would not be easily reached by city water. I would either have to lug hoses some fairly long distances or pump water to a tank and irrigate using a pump. I would love to hear your insights on ways to approach bidding a project such as this.
