The Plum Central station is a 38-floors condominium project, made of 2 towers and located near Bang Yai elevated metro station, in the North West of Bangkok. The residential building will host 1,013 appartments.

The Phase 1 of the project (first tower) started in September 2015 and will be completed aroundMarch 2018. The fast pace construction is madepossible by the use of "fully precast" concrete techniques.

The owner of the project Pruksa is operating its own precast plant for this project.

For this project, the objective of Pruksa was to be able to quickly erect precast panels (acting as shear walls) for all levels above ground. Dextra suggested for that purpose the use of Groutec couplers.

Groutec couplers, mounted on rebar Ø25mm previously prepared with Bartec thread. The couplers, installed at the bottom of each precast element, are then cast as part of the precast wall panel element.

After lifting the element to the upper floor at site, reconnection to protruding reinforcement is achieve by injecting non-shrink mortar. It is to be noted that Dextra does not provide the mortar, which instead can be sourced locally, generating significant savings. After injecting grout, bracing around each panel can be removed after 3 days.
