What a bank needs when opening a new transaction office
For a bank, a new transaction office has a fixed opening date. From the client’s side, the brief usually comes down to four points:
- Open on the scheduled date. Launch plans, staffing and IT systems are locked to that date. A one-week delay pushes back the whole business plan.
- Match the brand standards. Colours, logo, counters, glass partitions and signage must follow the bank’s identity guidelines in every detail.
- Pass cash vault and fire safety acceptance. These two items decide whether the office can start operating.
- One accountable contractor. The bank does not want to coordinate five or six contractors for structure, interiors, MEP, fire protection and the vault.
OCB Long Thanh came with all four requirements, on a site that was far from ready.
Project challenges
Two townhouses, not a commercial floor plate
The two houses had separate staircases, partition walls, floors and toilets. Turning them into one continuous transaction office meant demolishing and rebuilding from the staircase to the walls, floors and every toilet, while keeping the existing structure safe throughout demolition.
35 days instead of 45
A transaction office with a cash vault normally takes around 45 days to build. OCB required 35 days – more than 20% shorter – while the demolition and structural work was heavier than on a typical commercial unit.
Many trades overlapping
Structure, cash vault, MEP, fire protection, finishes and furniture all had to run within the same short window. Without tight schedule control, crews end up waiting on each other or working over each other, which leads to rework.
TECO’s approach
Scheduling backwards from the handover date
TECO planned backwards from 25 October, defined the critical path as demolition – structural renovation – cash vault, and arranged all other trades to run in parallel around it. The vault was started early because it takes the longest and needs separate acceptance with the bank.
Furniture produced in parallel at the workshop
As soon as the layout was fixed, counters, partitions, cabinets and desks went into production on CNC machines at TECO’s furniture workshop, while demolition was still under way on site. By the time rough works were finished, the furniture was ready to be delivered and installed.
Overtime and shift work on critical stages
TECO worked overtime and weekends on critical stages and assigned crews by zone so several trades could work at once without clashing.
Daily and weekly reports
The client received daily and weekly progress reports with site photos, so decisions could be reviewed and approved without delay.
Construction process
Demolition and opening up the two townhouses
The partition wall between the two houses was marked with a laser level, then cut and broken out exactly at the designed positions. Old wall finishes were stripped so everything could be redone consistently.



Structural renovation and staircase
Wall openings were strengthened and concealed electrical conduits were re-run. One old staircase was demolished, and a new steel-framed staircase was built to suit the transaction office layout.


Cash vault
TECO built the cash vault to OCB’s technical standards and completed acceptance together with the bank. For security reasons, this article does not describe the vault’s structure, location or equipment.
Wall, floor and toilet finishes
Walls were plastered and levelled with a laser before skim coating and painting. Floors were laid with large-format tiles. The toilets were completely rebuilt, from water supply and drainage to tiling, fixtures and glass partitions.




Electrical, fire protection and furniture installation
Lighting, power outlets, air conditioning and the fire protection system were completed in parallel with installing furniture from the workshop.


Handover
The OCB Long Thanh transaction office was handed over on 25 October 2026, exactly 35 days as required by the client. The two old townhouses became one continuous transaction office, in line with OCB’s brand standards, with a cash vault and complete electrical, plumbing and fire protection systems.










What the client gained
- Opened on schedule: 35 days, about 10 days shorter than the usual schedule for a transaction office with a cash vault.

- Joinery from TECO’s own workshop: control over samples, quality and installation timing; 24-month warranty.
