Pick your builder and let them guide you with regard to specific tasks you need to perform pre-construction and during construction.

Charles offers sound advice above ^^^.

Since every builder may sequence construction a little differently, getting a schedule from your chosen builder is probably the best source of the information you seek. Remember, that a planned schedule at the outset of construction is simply a plan which will change as unforeseen or unexpected events occur such as delays in materials and/or labor.

And of course, when it comes to builders you must decide between the options of competitive bids among several builders versus a negotiated construction contract with a single builder. Each approach has advantages and disadvantages. And when it comes to construction, you must also decide what sort of construction contract you most favor--lump sum, cost plus (with a max and shared savings provisions), or heaven forbid, time and materials.

Also keep in mind there a numerous activities to complete prior to construction: site selection and purchase, architectural design, design review and approval, building permit for construction, occupancy permit at substantial construction, punchlist and corrective work, etc.

And of course there's the financing, i.e., construction loan and permanent mortgage, among other things.

Good luck.

I found a quick and dirty one when we were starting...

Flo Mangan ha a great checklist.

Are you the builder, designer or owner. They each have different responsibilities and roles.
