Design-build project delivery brings unique scheduling challenges—design and construction overlap, design decisions affect construction sequences, and information flows differ from traditional delivery. The 6 week lookahead schedule provides essential visibility for managing these complexities.
Design-Build Scheduling Challenges
Design-build creates special planning requirements:
Overlapping activities: Design continues while construction progresses. The rolling lookahead schedule must track both design deliverables and construction activities.
Information dependencies: Construction activities depend on design completion. Drawings, specifications, and decisions must arrive before work can start. Construction lookahead software must track these information constraints.
Early procurement: Long-lead items must be ordered before design is complete. The 6 week lookahead schedule helps coordinate procurement timing with design progress.
Change integration: Design changes happen more frequently during construction in design-build. Look ahead schedule construction practices must accommodate this fluidity.
Why Six Weeks for Design-Build
The extended 6 week lookahead schedule serves design-build particularly well:
Design-construction gap: Design work must complete weeks before construction starts. Six weeks provides visibility into design deliverable timing and construction needs.
Procurement coordination: Long-lead items in design-build often have extended timelines. Six weeks captures more procurement within the planning horizon.
Decision timeline: Design decisions needed for construction can be identified six weeks ahead, giving design teams adequate notice.
Coordination complexity: Design-build's overlapping nature creates more coordination complexity, justifying the extended horizon.
Tracking Design Activities
The rolling lookahead schedule should include design work:
Design deliverables: Drawing packages, specifications, and design decisions appear as activities in the construction schedule app. Their completion enables downstream construction.
Design constraints: What does the design team need to complete their deliverables? Information, decisions, coordination—track these as constraints in lookahead schedule software.
Design-construction links: Project management software for construction should show explicit links between design deliverables and construction activities that depend on them.
Information Flow Management
Information is the key constraint in design-build:
Drawing release tracking: When will drawings be available? The 6 week lookahead schedule tracks drawing release dates as constraints for construction activities.
Specification timing: Specifications needed for procurement or construction appear as constraints. Construction lookahead software ensures they're identified early.
Decision identification: Design decisions (material selections, system choices, detail resolution) that construction needs are identified and tracked through the rolling lookahead schedule.
RFI management: Construction-generated questions need design answers. Construction software should track RFIs as constraints with response deadlines.
Early Procurement Integration
Design-build often requires ordering before design completion:
Long-lead identification: The 6 week lookahead schedule helps identify when procurement must start, even if final design isn't complete.
Design-for-procurement: Certain design elements must be completed early to enable procurement. Track these critical design paths in construction lookahead software.
Procurement constraints: Link procurement activities to design deliverables. Subcontractor management software coordinates trade-specific procurement with design releases.
Design-Build Coordination Meetings
Weekly lookahead meetings take different shape:
Design team inclusion: Design representatives should participate in rolling lookahead schedule reviews, seeing what construction needs from design and when.
Information status: Each meeting reviews design deliverable status and construction information needs. The construction schedule app shows these dependencies clearly.
Priority coordination: When construction has multiple information needs, meetings help design prioritize their work to support critical construction activities.
Change discussion: Design changes requiring construction adjustment surface in lookahead meetings for immediate coordination.
Last Planner System in Design-Build
Last planner system software adapts to design-build:
Design commitments: Design teams make weekly commitments like construction trades. "We will complete structural drawings for level 2 by Friday" is a trackable commitment.
Information constraints: The make-ready process includes design information as constraints for construction activities.
Cross-team PPC: Percent Plan Complete can track both design and construction commitments, revealing reliability across the combined team.
Fast-Track Considerations
Many design-build projects are fast-tracked:
Higher velocity: Fast-track delivery means tighter coordination between design and construction. The 6 week lookahead schedule becomes even more critical.
Multiple design fronts: Different building systems may be at different design completion levels. Construction lookahead software tracks these parallel design streams.
Risk management: Fast-track increases coordination risk. The rolling lookahead schedule helps identify risks early enough for mitigation.
Communication Patterns
Design-build communication differs from traditional delivery:
Unified team: Design and construction are on the same team, enabling more direct communication. Construction schedule app visibility extends to design team members.
Faster decisions: Questions can be resolved more quickly without contractual barriers. Field management software documentation still matters for project records.
Collaborative problem-solving: When constraints emerge, design and construction solve them together. Subcontractor management software facilitates this collaboration.
Technology Requirements
Design-build demands specific software capabilities:
Design activity support: Lookahead schedule software should handle design deliverables as activities, not just construction work.
Information constraint types: Constraint categories should include drawings, specifications, decisions, and RFI responses. Construction software must track these information types.
Design team access: Project management software for construction should provide appropriate access for design team members to see and update relevant information.
Integration capability: Connection to design document management systems improves coordination visibility.
Common Design-Build Failures
Avoid these planning failures:
Ignoring design in lookahead: Treating the rolling lookahead schedule as construction-only misses the critical design-construction interface.
Assumption of information: Assuming design will be ready without tracking creates surprises when construction arrives at missing information.
Insufficient lead time: A 3 week lookahead schedule may not provide enough visibility for design-build coordination. The longer horizon often proves necessary.
Siloed planning: Design and construction teams planning independently, then trying to coordinate, is less effective than joint planning.
Conclusion
Design-build project delivery creates scheduling challenges that the 6 week lookahead schedule is well-suited to address. The extended visibility enables coordinating overlapping design and construction activities, tracking information dependencies, and managing early procurement needs.
Success requires treating design deliverables as rolling lookahead schedule activities with their own constraints, including design teams in planning processes, and maintaining tight coordination between design and construction progress.
Construction lookahead software configured for design-build—with design activity support, information constraint tracking, and cross-team visibility—becomes essential infrastructure for design-build project success.
