Woodlam's Forestry Approach
Overview
Installation determines whether engineered geometry is preserved on site. Components are positioned to the structural grid, fixed using the specified connector schedule, and assembled using the issued sequencing and layout guides.
By controlling tolerances, bearing contact, movement allowances, and moisture detailing during assembly, Woodlam reduces tolerance drift, connection stress, and early finish or maintenance issues.
Benefits
Preserve structural alignment
Grid-based placement and continuous measurement keep beams and frames within engineered tolerances, preserving bearing alignment and load-path intent.
Reduce site improvisation
Sequenced installation guides reduce RFIs, unplanned trimming, and connector substitutions that can change structural behaviour.
Protect finishes
Handling and staging controls protect factory-applied coatings and reduce abrasion, denting, and contamination at exposed surfaces.
Improve installation speed
Pre-machined components reduce site cutting and rework, supporting faster structural assembly when foundations and anchors are within tolerance.
How It Works
Installation executes structural assembly under engineered tolerances. Each step preserves alignment, load transfer, and finish quality within real construction environments.
Step 1 – Confirm site readiness and baseline conditions
Before assembly begins, teams verify:
-
Foundation level and flatness
-
Structural grid set-out and reference points
-
Anchor bolt position and embedment
-
Drainage readiness at exposed interfaces
-
Crane access routes and lifting plan
-
Moisture exposure conditions for stored components
Early checks prevent cumulative deviation during stacking.
Output: Verified base conditions ready for component placement.
Step 2 – Follow engineered sequencing and installation guides
Installation is supported by:
-
Layout plans with beam and panel mapping
-
Axonometric assembly diagrams by zone
-
Section details for bearings, gaps, and interfaces
-
Connector schedule and fixing sequence
-
Temporary bracing and stability notes where required
Sequencing mirrors the delivery bundles and installation phases.
Output: Assembly executed to the issued documentation and sequencing logic.
Step 3 – Position and secure structural elements precisely
Structural elements are:
-
Positioned to the structural grid and tolerance limits
-
Checked for bearing contact and seat depth
-
Verified for camber orientation where specified
-
Fixed using the specified connectors, bolt grades, and fastener types
Concealed connectors and anchoring systems are installed as detailed to preserve connection behaviour.
Output: Structural geometry and load paths maintained during fixing.
Step 4 – Control moisture, movement, and finish protection
Indonesia’s climate requires moisture and drainage discipline during installation.
Installation controls include:
-
Moisture checks before final fixing where components were exposed or stored on site
-
Preserving designed movement gaps and slip allowances
-
Avoiding horizontal water traps at bearings and steel interfaces
-
Maintaining clearance from splash zones and ensuring drainage away from bases
-
Protecting finished surfaces during staging and lift operations
Output: Movement allowances and moisture detailing preserved during assembly.
Step 5 – Secure traceability and compliance documentation
During installation:
-
Lift routes and staging zones are defined by phase
-
Daily briefings confirm tolerances, connector checks, and sequence
-
Alignment is checked before permanent fixing at each bay or zone
-
Final geometry is verified at handover checkpoints
Output: Completed assembly verified against grid, tolerance, and connector requirements.
Tolerance Drift and Cumulative Error
Installation is where small deviations can compound across a grid. A few millimetres of foundation or anchor misalignment can affect bearing contact, connector seating, and façade alignment over long spans.
Tolerance control preserves engineered geometry.
Tolerance drift occurs when:
• Foundations deviate from design levels
• Anchor bolts shift during casting
• Beams are installed without grid verification
• Camber orientation is reversed
• Minor offsets are accepted without correction
Each deviation may appear minor. Across structural grids, these deviations compound.
Structural geometry must be verified continuously, not assumed.Installation relies on:
• Confirmed grid baselines
• Verified foundation levels
• Laser alignment checks
• Continuous measurement during assembly
Structural elements are positioned within engineered tolerances. Alignment is checked before permanent fixing.
Correction becomes exponentially harder once structural stacking progresses.Glulam beams may include engineered camber.
If orientation is incorrect:
• Deflection performance changes
• Visual sag becomes apparent
• Load distribution assumptions are altered
Camber direction and bearing conditions are confirmed during placement.Tolerance control ensures:
• Load paths remain accurate
• Connection seating remains consistent
• Structural geometry aligns with modelling
• Facade and interior interfaces remain true
Installation preserves structural intent.
Movement Management in Tropical Climate
Indonesia’s humidity cycles require controlled installation practices.
Engineered expansion allowances and moisture checks must be preserved during assembly. Failure to manage movement leads to stress concentration, cracking, and long-term distortion.
Movement control protects durability.
Engineered timber systems include defined movement allowances.
During installation:
• Expansion gaps must not be compressed
• Fasteners must not restrain movement unintentionally
• Concealed connectors must allow controlled slip where specified
Restrained movement creates internal stress.
Allowance must remain functional after fixing.Components exposed to rain or high humidity before fixing can absorb surface moisture.
Before permanent fixing, teams verify:
• Moisture content where exposure occurred
• Surface dryness at coated interfaces
• No standing water at bearings and connector zones
Fixing timber while wet increases movement stress after installation.Exterior installation requires:
• Sloped bearing surfaces or drainage paths
• Clearance above splash-back zones
• Ventilated gaps at steel interfaces where specified
• No horizontal ledges that trap water at connections
Water that cannot drain or dry will shorten service life. Detailing must be maintained during installation, not simplified.Climate-aware installation ensures:
• Controlled dimensional movement
• Reduced finish distress
• Lower joint stress
• Improved long-term stability
Durability is preserved during assembly.
Connector Systems and Structural Integrity
Timber structures rely on connections to convert individual components into a single load-bearing system.
Connector systems are engineered to transfer forces between beams, columns, and supporting elements according to the structural model. During installation, the precision of connector placement, hardware selection, and assembly sequence determines whether these forces are transferred as designed.
Small deviations in connectors can significantly affect structural performance.
Installation discipline ensures the engineered load paths remain intact.
During installation:
• Specified connectors are used without substitution
• Bolt grades and fastener types are verified
• Edge distances are maintained
• Tightening torque follows specification
Improper fastener selection or placement alters structural capacity.
Connection discipline is structural discipline.Installation checks confirm:
• Full bearing contact and correct seat depth
• No unintended gaps at load-transfer faces
• Correct orientation of plates, brackets, and hold-downs
• Alignment of connectors to the designed load path
Load transfer must match the structural model.In seismic regions, connections are designed to yield in controlled zones.
Improper installation can:
• Reduce ductility
• Shift failure mode
• Create brittle fracture risk
• Increase drift under lateral load
Connection detailing must be executed precisely to maintain seismic hierarchy.Installation includes defined checkpoints:
• Tolerance verification
• Moisture confirmation
• Connector inspection
• Alignment review
• Final geometry confirmation
Sign-off ensures no deviation progresses unchecked.Connector discipline ensures:
• Reliable load transfer
• Preserved ductility
• Long-span stability
• Reduced structural liability
Structural integrity is secured during installation.
