Local Factors That Shape Workmanship
The same method applies to every workmanship analysis: identify what was required, examine what was built, and explain the difference. On a Chicago project, several local factors affect both the requirement and the evaluation.
| Chicago factor | Why it matters to workmanship |
|---|---|
| Older building stock | Renovations must tie into existing masonry, framing and floors that are rarely plumb or level |
| Climate | Freeze-thaw cycles and seasonal humidity swings affect wood flooring, trim, doors and exterior details |
| Union trades | Trade jurisdiction and crew practices affect who performed which work and how |
| Permit and inspection system | Chicago Department of Buildings records show what was permitted and inspected, and when |
| Occupied buildings | Much Chicago work is renovation in buildings that stay in use |
Older Buildings and Existing Conditions
A large share of Chicago construction is work in existing buildings: two-flats, three-flats, bungalows, greystones, frame cottages, older commercial blocks and mid-century institutional buildings. New work in these buildings has to accommodate floors that slope, walls that are out of plumb and framing that has moved over decades. A competent contractor identifies those conditions and accounts for them. Paul evaluates whether the contractor did so, and whether a condition reflects the new work, the existing building, or the connection between them.
Chicago Weather and Finish Work
Chicago's climate is hard on finishes. Wood flooring, trim and doors respond to the swing from humid summers to dry, heated winters. Work installed in a building that is not yet closed in and conditioned, or with materials that have not acclimated, is more likely to fail. Paul reviews the schedule, site conditions and manufacturer instructions to see whether materials were installed under the conditions the instructions required, and he considers seasonal movement before attributing a condition to workmanship.
Permit and Inspection Records
Chicago Department of Buildings permit and inspection records can show what work was permitted, under which code, and when inspections took place. They are useful for establishing the timeline and the applicable code edition. A passed inspection is evidence that the inspected item was found acceptable at that point; it does not establish that all work met the contract or manufacturer instructions. Paul uses these records for what they show and no more. See Chicago construction code compliance.
Local Contractor Practices
Workmanship on Chicago projects is performed within local practices: union trade jurisdictions on many commercial and public projects, common local construction details, and supervision practices shaped by occupied-building work. Paul's three decades in those practices let him describe what a competent Chicago contractor or tradesperson would have done. See Chicago contractor practices.
