“Can you explain schematic, design development, and construction docs?”

Schematic Design (SD): Early-stage concepts. Focuses on overall layout, form, and basic function. It’s about exploring ideas and options.

Design Development (DD): Refined plans. Dimensions, materials, systems, and aesthetics are defined. The design starts to lock in key decisions.

Construction Documents (CD): Detailed, technical drawings and specifications used by contractors to build accurately. Includes exact measurements, materials, and instructions for construction.

“What’s a fire-rated wall and why do we need them?”

Fire-rated walls resist fire for a set time, protecting people and property. They’re required between tenants, around stairwells, corridors, and any space where codes demand separation for safety.

“Why do some ceilings cost so much more than others?”

Ceiling cost depends on material, height, acoustics, and complexity.

- Basic acoustic suspended ceiling: simple grid and tiles, lower cost, moderate acoustics.

- Drywall or high-performance acoustic suspended ceiling: more materials and labor, better sound control, slightly higher cost.

- Specialty or architectural ceilings (vaulted, coffered, wood, metal, custom patterns): higher cost due to design complexity, precision installation, and premium materials.

“What is LEED certification and does it matter?”

LEED verifies a building is sustainable, energy-efficient, and healthy. It can increase value and may be required for certain tenants. Before you construct as a tenant, see if you need LEED certification.

“What are construction contingencies for?”

A contingency is extra budget set aside for surprises. It helps keep the project on schedule and prevents cost overruns.

“What counts as life safety systems?”

Life safety includes fire alarms, sprinklers, exit signage, and safe egress paths. Changes to any of these almost always need a permit.

“Why start a project with Programming?”

Programming defines how much space you truly need and how it’s used. Getting it right up front prevents overspending and ensures your design fits today and future growth.

“What’s a punch list and why does it matter?”

A punch list is a final set of fixes before completion to ensure everything meets expectations.

“What’s a change order and why do they happen?”

Change orders adjust scope, schedule, or cost after construction begins, usually from design changes or unexpected issues. A strong design-build team minimizes them by planning carefully upfront.

“How does WDI ensure safety on site?”

WDI keeps projects safe through regular site inspections, strict safety protocols, and ongoing training. Our teams are known to us, monitored closely, and held accountable—ensuring hazards are identified and addressed before they become issues.

“What exactly is Workplace Strategy?”

Workplace Strategy looks at how people use space—then aligns design to boost productivity, flexibility, and growth. Done early, it avoids expensive rework and wasted square footage and plans ahead for future expansion.

“What is a Feasibility Strategy and why bother?”

Feasibility studies explore all building or site options before design begins. They flag expansion limits, identify options, flag code issues, and raise awareness to cost risks—saving time, money, and surprises.
