WHAT LOOKS
SIMPLE
CAN BECOME
COMPLICATED

Tenant improvements carry hidden structural consequences that are easy to underestimate at the start of a project.

Building Knowledge

Treated as a generic structure — existing system not studied before design begins

Structural system studied early so design reflects how the building actually works

Early Clarity

Critical decisions made before structural constraints are understood

Structural input provided upfront — owners and architects know what's possible early

Design Quality

Innovative ideas compromised when engineer cannot technically support the vision

Architecture protected — structural solution is strong enough to support the design intent

Field Coordination

Generic details cause conflicts during construction, leading to RFIs and delays

Details tailored to actual site conditions — drawings are clear and practical to build

Plan Check

Slow or stalled approvals because drawings don't anticipate city requirements

Review moves predictably — drawings are prepared to meet what the city expects

Fee Accuracy

Low initial proposal hides scope gaps — add services and cost overruns follow

Proposal reflects real scope from the start — clients avoid surprise costs

Communication

Poor coordination between team members causes uncertainty and schedule loss

Clear coordination across structural, architect, contractor, and owner — fewer delays

Option 02Two-column reveal — problems fill left column first, then solutions answer on the right
