Started the new year with a basement development south of the city. Not my normal project, drive time, tiny value, new jurisdiction and business licence. I’ve reminded myself how hard it can be to fixed price bid a job. You’ve got to have a degree of omnipotence to get anything right at the planning stage. No budget ever is as accurate as it should be, within say 5% of actual. You could spend days and days estimating work and still overlook some detail. Make sure that contingency line item is in there!
