After establishing design direction through Pre-Concept, Schematic Design, and Design Development phases, the architectural process advances to Construction Documents (CDs)—where design intent transforms into precise instructions for builders. This fourth phase in the AIA design sequence produces the comprehensive documentation that forms the legal and technical basis for construction.
At Solid Void, we approach CDs as the critical translation point between architectural vision and construction reality. The quality of this documentation directly impacts construction efficiency, budget adherence, and ultimately, whether the completed building fulfills the promise established in earlier design phases.
Construction Documents (CDs) transform design intent into comprehensive instructions for builders, establishing legal and technical parameters for project execution. This phase produces coordinated drawings and specifications that communicate exact requirements for materials, assemblies, and systems. Success demands meticulous documentation, quality control, and strategic decision-making. For clients, investing in thorough CDs mitigates construction risk, prevents costly change orders, and ensures the built project fulfills the design vision established in earlier phases.
The Purpose and Value of Construction Documents
Construction Documents serve multiple essential functions:
Translating design intent into buildable instructions
Establishing performance requirements for all building elements
Providing the basis for accurate contractor pricing
Creating legal parameters for the construction contract
Enabling regulatory review and permitting
Establishing quality standards for construction
Documenting design decisions for future reference
The CD phase typically advances documentation from the ~65% completion of Design Development to 100% completion—creating the comprehensive set of instructions builders will follow during construction.
CD Phase Deliverables Matrix
Document Type | Purpose | Key Components | Client Value |
Working Drawings | Physical representation of all building elements | Plans, elevations, sections, details | Ensures spatial requirements and dimensional accuracy |
Specifications | Performance standards for materials and systems | CSI-formatted technical requirements | Establishes quality standards and prevents substitution issues |
Schedules | Detailed listings of repetitive elements | Door, window, finish, equipment schedules | Ensures consistency across similar components |
Engineering Documents | Technical requirements for building systems | Structural, mechanical, electrical, plumbing drawings | Coordinates interdisciplinary systems and ensures code compliance |
Regulatory Documentation | Information required for permitting | Code analysis, energy calculations, accessibility compliance | Prevents permitting delays and code issues |
Key Components of Construction Documents
Working Drawings Development
CD phase working drawings advance from Design Development level to fully detailed construction instructions including:
Complete dimensioning and annotations
Detailed wall sections at all condition types
Connection details at material transitions
Waterproofing and thermal barrier continuity
Expansion joint locations and details
Structural connections and reinforcing
Comprehensive interior elevations and details
Site details and civil coordination
For the Westlake Financial Headquarters, our CD set included over 85 unique wall sections and 120 detail drawings addressing specific conditions throughout the building. This level of documentation prevented ambiguity during construction and reduced RFIs by approximately 40% compared to industry standards for similar projects.
Specifications Development
While drawings show "where" and "what," specifications detail "how" and establish performance requirements through:
CSI MasterFormat organization (Divisions 01-49)
Detailed material and performance requirements
Installation standards and tolerances
Quality assurance provisions
Testing and verification requirements
Submittal and mockup processes
Product options and substitution procedures
For complex projects, specification development requires careful coordination with drawings to prevent conflicts or gaps. The Carson County Courthouse renovation project's 980-page specification addressed unique requirements for historic preservation, security systems integration, and specialized acoustic performance—elements difficult to communicate through drawings alone.
Consultant Coordination
CD phase requires rigorous coordination across disciplines:
BIM coordination to detect and resolve conflicts
Shared reference points and control lines
System interface details at discipline transitions
Performance coordination across related systems
Specification coordination to prevent conflicts
For Mason Memorial Hospital's surgical center, our BIM coordination process identified and resolved over 450 significant system conflicts during CDs. Each conflict resolution was documented with responsibility assignments and timeline requirements, ensuring clean handoffs between design disciplines.
Code Compliance Documentation
CDs must demonstrate comprehensive regulatory compliance:
Building and fire code analysis
Accessibility compliance details
Energy code documentation
Specialized requirements (health department, etc.)
Local zoning and planning compliance
For the Parkside Mixed-Use Development, our CD phase included development of a 45-page code narrative with specific references to drawings demonstrating compliance with complex requirements for mixed occupancies, fire separations, and accessibility transitions between diverse program elements.
The CD Development Process
Document Production Strategy
Effective CD production requires strategic organization:
Sheet hierarchy establishing information flow
Standard detail libraries for consistent approaches
Annotation standards for clear communication
BIM standards for model development
Quality control protocols at production milestones
At Solid Void, we've developed a "Documentation Roadmap" approach that establishes clear sequences and dependencies for drawing production. This system ensures foundations for subsequent documentation are established before dependent elements are detailed.
Quality Control Implementation
Thorough quality control prevents costly errors:
Interdisciplinary clash detection
Peer review at critical milestones
Technical accuracy verification
Coordination checking between drawings and specs
Constructibility review with construction experts
Regulatory pre-review when appropriate
Our QC process includes dedicated coordination checks at 65%, 90%, and 100% completion, utilizing both internal review and third-party constructibility analysis. For the Clearwater Performing Arts Center, this process identified 27 significant coordination issues during documentation rather than during construction, preventing approximately $1.2M in potential change orders.
Tools and Technologies
Modern CD production leverages advanced tools:
BIM for 3D coordination and documentation
Cloud collaboration platforms for team integration
Automated clash detection and verification
Specification writing software integrated with BIM
Digital markup and review tools
The Riverview Medical Campus project utilized a complete BIM approach, with all consultants working in coordinated 3D environments. This integration enabled real-time conflict resolution and improved documentation accuracy. When field verification of existing conditions revealed unexpected structural elements, the integrated model allowed rapid analysis of impacts across all systems and documentation sets.
Client Engagement During Construction Documents
Strategic Decision Management
While major design decisions should be complete before CDs, remaining decisions require strategic management:
Final material and product selections
System performance specifications
Quality level determinations for components
Alternates and value engineering implementation
Effective client engagement during CDs focuses on:
Clear deadlines for remaining decisions
Documentation of decision impacts across drawing sets
Cost implications of selections and changes
Schedule impacts of delayed decisions
For the Westside Corporate Campus, we developed a decision tracking system that clearly communicated the "last responsible moment" for each remaining client selection. This approach prevented decision paralysis while ensuring clients maintained control over critical elements.
Cost Management Integration
CD development directly impacts construction cost through:
Detail development that eliminates ambiguity
Clear quality standards that prevent misinterpretation
Coordinated systems that prevent field conflicts
Comprehensive scope definition that reduces contingencies
The Eastridge Office Tower demonstrates effective cost integration during CDs. When developed details revealed cost concerns with the custom curtainwall system, we conducted targeted value engineering focusing on connection details and glass specifications rather than visible design elements. This approach maintained design integrity while bringing costs within budget parameters.
Change Management
Late changes during CDs can have cascading impacts:
Drawing coordination disruption
Specification conflicts
System performance impacts
Schedule implications
Cost ramifications
For the Hamilton Research Campus, we developed a formal change impact assessment process during CDs. When the client requested modifications to laboratory equipment layouts late in documentation, this process produced a comprehensive analysis showing impacts across mechanical, electrical, structural and architectural documentation. This information allowed informed decision-making about proceeding with changes versus maintaining the established design.
Common CD Phase Challenges
Documentation Completeness vs. Schedule Pressure
Pressure to complete CDs quickly often conflicts with thoroughness requirements. Incomplete documentation creates significant construction phase problems through RFIs, change orders, and schedule delays.
For the Lakeside Community College Science Building, schedule pressure threatened documentation quality as the deadline approached. Rather than compromising completeness, we implemented a phased document release strategy: core/shell documentation followed by interior fit-out documents. This approach maintained thoroughness while accommodating the project schedule.
Coordination Across Disciplines
Modern buildings contain numerous interdependent systems requiring precise coordination. Documentation must address these relationships explicitly to prevent costly field conflicts.
The Memorial Hospital Imaging Center demonstrates effective coordination strategies. Critical ceiling spaces containing medical gas, specialized electrical, and precise ventilation requirements underwent virtual construction during CDs. The team created detailed 3D sequence models showing exact installation ordering for interrelated systems, preventing conflicts during actual construction.
Balancing Detail vs. Contractor Flexibility
Construction documents must be sufficiently detailed while allowing appropriate contractor flexibility for means and methods. Over-specification can limit innovation and increase costs; under-specification creates ambiguity and quality control challenges.
For the Carson County Courthouse restoration, this balance required careful consideration. Historic elements received highly detailed documentation specifying exact replication requirements, while new infrastructure systems received performance specifications that established outcomes while allowing contractor expertise in implementation methods.
Case Study: CD Phase Impact
Glendale Transit Center
The Glendale Transit Center—a complex multi-modal facility integrating bus, light rail, and pedestrian systems—demonstrates the critical importance of thorough Construction Documents.
Initial design phases established an ambitious architectural concept featuring an undulating canopy structure spanning multiple transit platforms. Design Development resolved major technical approaches but left numerous details for the CD phase.
During Construction Documents, several significant challenges emerged:
The complex geometry of the canopy created challenging waterproofing conditions at panel transitions
Structural connections required precise tolerance control while accommodating thermal movement
Integration of multiple transit system technical requirements created coordination complexity
Lighting, drainage, signage, and security systems competed for limited space within canopy elements
Rather than simplifying the design, the team invested in extraordinarily detailed documentation:
Custom 3D modeling of all connection conditions
Detailed fabrication-level drawings of key components
Comprehensive waterproofing details at all transitions
Sequenced installation instructions for interdependent systems
Full-scale mockup specifications for critical assemblies
This investment in thorough CDs produced remarkable results during construction. The project experienced only 12 architecture-related RFIs (compared to an industry average of 35-45 for comparable projects), completed on schedule, and finished less than 1% over the established budget despite its technical complexity.
The transit authority's post-project analysis credited the exceptional documentation quality with preventing an estimated $2.1M in potential change orders and approximately 4 months of potential delays. This outcome demonstrates how thorough Construction Documents provide direct, measurable value for clients through risk reduction and quality assurance.
Transitioning to Construction Administration
Effective CDs create the foundation for successful Construction Administration by:
Establishing clear quality expectations
Detailing inspection and testing requirements
Defining submittal review processes
Creating standards for substitution requests
Documenting design intent for field decisions
For the Westfield Performing Arts Center, we developed a comprehensive "Design Intent Guide" as part of the CD deliverable. This document—separate from legal construction documents—explained critical design relationships and priorities to guide field decisions during Construction Administration.
Conclusion
Construction Documents transform design intent into buildable instructions. While less conceptually glamorous than earlier design phases, CDs have the most direct impact on construction outcomes through their role as the primary communication tool between designers and builders.
At Solid Void, we view thorough Construction Documents as essential risk management tools for our clients. The investment in comprehensive, coordinated documentation consistently delivers returns through reduced construction conflicts, fewer change orders, and built outcomes that faithfully execute the design vision.
For clients navigating architectural services, understanding the value of Construction Documents helps establish appropriate expectations and resource allocation. While it can be tempting to accelerate this phase or reduce its scope, such compromises typically create significantly greater costs during construction.
The most successful projects recognize that excellence in Construction Documents is not merely a technical exercise but a critical implementation of design thinking—ensuring architectural visions become built realities without compromise.
This article is the fourth in Solid Void's six-part series exploring the AIA design phases. Our previous installments examined Pre-Concept Design, Schematic Design, and Design Development, and our next will explore Construction Administration—where documentation is translated into physical reality through the construction process.
