? Key questions to answer
Is each work package ready to start safely?
Check applicable permissions, current drawings, preceding work, access and the contractor’s safety arrangements before opening the next work front.
SPrimary responsibilitySam · Construction manager
With: Eli (site & civil engineer); Morgan (project architect); Noor (power & cooling engineer).
Trade contractors manage their work methods and crews.
Does the installed work match the intended performance?
Use inspections, submittals, field observations and installation records to verify quality before systems are concealed or handed over.

Inspectors and specialist testing teams make their own findings.
↳ Key problems to solve
Site and trade interfaces causing unsafe work or rework
Sequence grading, structure, enclosure and fit-out; resolve clashes through documented design responses and keep work fronts coordinated.

Why this stage matters
Can we deliver safely, on time and on budget?
Construction is a controlled sequence of work, inspections and decisions. A forecast combines what has been paid, what is committed and what is still expected. A change order is not simply an invoice: first establish entitlement, scope, quantities and time impact. Safety, quality and contractual obligations remain binding even when budget pressure increases.

Hands-on
You are the project’s development lead. Evaluate the loading change and expediting choice against contingency and schedule. Use the fictional evidence below, make a choice and explain what you would verify.

Change request 07
Revised loading layout: $180K. Required to serve the agreed tenant program; scope entitlement still needs review.
Supplier update
Switchgear delayed four months. $120K acceleration can recover two months; require written confirmation.
Known direct changes$180,000
Remaining delay4 months
Uncommitted risk headroom$534,311
What your choices mean
Direct changes use $180,000; extra financing carry is $185,689. Together they consume $365,689 of the original $900K contingency, leaving $534,311. The forecast adds the change to the gross budget while retaining the full contingency allowance; releasing that allowance is a separate decision. Verifying scope, entitlement and a written acceleration commitment before authorization is appropriate.
