Pedestrian Bridge over Pikurga River in Latvia

In designing this pedestrian bridge, we particularly took into account its beauty and durability. Construction was fast, with minimal environmental impact. We built the bridge out of 633 wooden parts, fully assembled it on the grounds of our factory, and transported it pre-assembled to its location. 

  • Location
    Ulbroka, Stopiņu novads (Latvia)
  • Year of construction
  • Dimensions
    Length 14 m, width 2.5 m
  • Client
    Municipality of Stopiņu county (Latvia)

The role of ZAZA TIMBER Engineering (previously: Rodentia) in this project:

- Development of a full design project
- Detail drawings
- Technical drawings for manufacture and assembly.

The span of the pedestrian bridge is 14 m. The bridge has curved main beams and a straight deck, which is achieved by varying the placement of the cross beams.

To improve the longevity of the bridge, the main beams have a horizontal tin cladding and ventilated cladding with vertical boards that follow the curvature of the beam.

To provide better ventilation and prevent moisture traps on the contact surface, plastic distancers were used for the deck and deck beams.

Design time: 1 month.

ZAZA TIMBER Production (previously: IKTK) made both the glulam structures and other timber details for the deck, cladding and railings.

The volume of timber used in this project was not large (12 m3), but there was a large variety of parts, with the total number of parts standing at 633. Glulam structures were made of pine with strength class GL24h.

We made the main beams, cross beams, diagonal beams, deck and railing beams out of glulam. The longest beams were 14 m long and 1 m tall.

We also manufactured the remaining parts for the deck, cladding and railings.

We undertook a range of finishing jobs: drilling, milling etc.

Manufacturing and assembly time: 2 months.

ZAZA TIMBER Construction (previously: Igate Būve) was responsible for the entire construction cycle of the bridge.

Bridge construction included the construction of an embankment, the drilling of piles and the concreting of the pile cap.

To protect the bridge structures against damp and other weather, we treated the bridge’s load-bearing structures several times: high-pressure treatment followed by Koppers oil. We also treated the rest of the wooden details.

We assembled the entire bridge on the ground of our factory, including constructive protection solutions: cladding for the boards and tin. We delivered the bridge to its location already assembled, where we did the final assembly and installation work.

Construction time: 3 months.
