@Alexander Straffin and @Rob Hinh. Welcome to the world of real estate development and construction.
First, two vastly different sides aspects of real estate, which explains why there are not books that combine both topics.
A prefab building may/can simplify the construction sequencing process, but not sure I understand your comment about "lowest risk possible". Having one vendor accomplish many of the trades at a fix price - can reduce the risk from a construction budget perspective. However, there are many other factors to consider on the development side.
Role of the developer is to put together the vision, financing and ownership of the project. Determining what gets built, how much gets built, what goes into the building, the end use of the property, and how to capture the economic value for that vision. It involves working with equity, loans, buyers, sellers, mortgage brokers, real estate brokers, attorneys, title companies, insurance, municipalities, architects, engineers, and contractors.
Role of the contractor is to build what has been specified for the agreed upon cost of the work. It involves coordinating the work amongst 16 to 20 potential subcontractors to work as efficiently as possible so each trade does their job as best as possible. Specifying a prefabricated building may reduce/limit the scope of work for approximately 75% of those trades. For instance, a prefabricated building may have the rough and most trim in the building upon delivery. However, it still requires an onsite electrician to provide the service and make the necessary connections. Same is true for plumber and HVAC.
As a developer, I think it is important to assess the risk in specifying a prefabricated building versus a custom building. For instance, in many of the communities we work in, prohibit prefabricated buildings because the inspectors can not inspect inside the walls prior to the installation of drywall. So for us, it increases the risk. We work around this by installing prefabricated components - trusses, walls, floor decks, concrete, etc.
We always first discuss our concepts with the local municipalities to determine the viability of the project - zoning, construction, etc. Next, we discuss with real estate brokers to determine the receptivity of our concept in the market place. Then we work to get bids to determine the financial viability of the project.
Hope that helps provide some guidance as to how to begin approaching the project.
