Alerce: expansion of Chilepanel's OSB plant, engineered on the point cloud of the existing plant

FIG 01 Forming line building, before construction · Chilepanel, Chile

The Alerce project takes the OSB plant that Chilepanel operates in La Unión from about 80,000 to between 110,000 and 120,000 m³/year, with new areas for debarking, drying with emissions control, screening, fines grinding and blending. ProHolz is carrying out the basic and detailed engineering of the expansion, integrated with the engineering of the manufacturer of the new equipment.

ProHolz engineers the project and carries out technical inspection of the installation; procurement and construction stay with the client.

Interferences with the operating plant showed up in the model, before construction

The plant was laser scanned, and ProHolz built the 3D model of the expansion on that point cloud. The interference report identified 30 points of conflict between the new areas and the operating line, from debarking to the press outfeed.

ProHolz covers five workstreams of the expansion

  1. 01

    Layout, auxiliary structures and electrical

    3D model of the new areas; foundations and structures for conveyors, silos, platforms and pipe racks; new electrical rooms, cable trays and cables.

  2. 02

    More than 500 isometric sheets

    Deluge, spark extinguishing, compressed air, dryer emissions, effluents, process water and resin, with line lists, valve lists and bills of materials.

  3. 03

    Hood and extraction for the existing press

    Hood layout and structure, ductwork with fabrication drawings, and fan specification.

  4. 04

    Coordination with the new equipment manufacturer

    Design meetings every two weeks since January 2025.

  5. 05

    On site since May 2026

    Technical support during installation and, since June, resident inspection of mechanical and structural work.
