Team Collaboration

From the outset, XLam will work closely as partners with the project team, bringing a wealth of experience to early design decisions, forward planning and construction management.

Speed on site is achieved through comprehensive front end preparation. XLam provides early practical assessment and advice, works closely with the project team and if required will recommend consultants with expertise in CLT.

Working with the contractor, XLam will consult on job programming and scheduling for manufacture. Lead time is necessary to secure delivery to meet the contract program. The manufacturing lead time commences at the date of signing the Purchase Agreement.

XLam supports engagement with the Relevant Building Surveyor or Building Consent Authority, and where applicable the Fire Authority, to build cooperation and resolve any questions around approvals.

Design Review

The structural properties, appearance, and passive fire design benefits of XLam panels offer new and unique opportunities to designers. For example, walls may be utilised as beams to carry floor and roof loads; the use of cantilevers permits longer spans; lintels may be reduced or eliminated; engineered wood can be a striking expression of building design.

XLam’s highly qualified resources in engineering, architecture, construction and site management are available to guide and assist the project design team from the earliest concept development.

Initial design decisions will play the largest part in governing project viability and economic outcomes. The most economical building outcomes are reached where CLT is integrated at the conceptual stage so that its manufacturing and performance capabilities can shape decision-making. An early design consultation with XLam will optimise the performance of CLT, dealing with considerations such as economical panel sizes, orientation, tolerance for assembly, appearance, durability, buildability and construction sequencing.

Workshop Drawings

During the design development phase, XLam will advise on structural considerations, panel thicknesses and spans, CLT layout and connection details.

Workshop Drawings

On receipt of fully dimensioned electronic drawings, the XLam draughting team will prepare a 3-D model using advanced Cadwork CAD/CAM software. The location of proposed panel joints is added to suit manufacturing requirements, together with joint profiles to suit the engineer’s connection details. These constitute the workshop drawings for final approval and sign-off.

The approved Cadwork model is then exported to Lignocam which drives the manufacturing process from initial assembly of board layers through to CNC machining of the panels to precise dimensions, ready for delivery to site.

Cost Planning

Given sufficient preliminary design information, XLam will provide an early estimate of likely CLT supply costs to facilitate project planning. This entails establishing floor spans, loadings, anticipated bracing, and a general understanding of design requirements and complexity. Subject to agreed terms, XLam will then work with the customer and design team on refining design aspects to maximise project cost benefit, leading to a fixed price supply quotation based on contract documents.

Permit Applications

Building approvals and building consents are processed under the Alternative Solution provisions of the Australia and New Zealand Building Codes. XLam assists applications with the supporting technical documents required to substantiate performance requirements under the codes.

Contract Support

Good planning and organisation is key to the speed of prefabricated construction. XLam works with the contractor to coordinate delivery with the contract program, identify the best assembly sequence, supply panels in prearranged order, and advise on site management. Checklists include site access, crane weight, lifting procedure, building tolerances and weather protection. Fixings can be scheduled and supplied by XLam. On-site support is given as required.
