When most people think of building or renovating a commercial space in Bangladesh, they imagine managing two separate teams: a design firm and a construction contractor. This fragmented approach leads to communication gaps, budget overruns, and schedule delays. There is a better way: EPC — Engineering, Procurement, and Construction — the integrated project delivery model used by House De Arch to deliver complex projects faster, more cost-effectively, and with a single point of accountability.
What Is EPC?
EPC stands for Engineering, Procurement, and Construction. Under an EPC contract, a single firm takes full responsibility for the entire project lifecycle:
- Engineering: Architectural and interior design, MEP engineering, structural engineering, and all technical specifications
- Procurement: Sourcing, purchasing, and managing all materials, equipment, furniture, and fixtures
- Construction: All civil works, fit-out, installation, commissioning, and handover
The EPC contractor — House De Arch — is responsible for delivering the completed project to an agreed specification, within an agreed budget, and by an agreed date.
EPC vs Traditional Design-Bid-Build
| Factor | Traditional | EPC (Integrated) |
|---|---|---|
| Accountability | Split between designer and contractor | Single point — EPC firm |
| Timeline | Sequential (design → tender → build) | Parallel (design and procurement overlap) |
| Cost certainty | Price confirmed only at tender | Fixed lump sum at contract award |
| Design-build conflicts | Common | Eliminated — same team throughout |
| Client management burden | High — client coordinates multiple parties | Low — one relationship, one contract |
Key Benefits of EPC Delivery
Faster Delivery
Because design and procurement overlap rather than running sequentially, EPC projects typically complete 20–35% faster than equivalent design-bid-build projects. For businesses paying rent from handover, this time saving has direct financial value.
Cost Certainty
EPC contracts are fixed-price, agreed before work begins. Budget surprises are eliminated. House De Arch absorbs the risk of material price movements and scope clarifications within the agreed contract sum.
Quality Assurance
When the team that designed a space also builds it, there is no “lost in translation” between design drawings and physical reality. Subtle design intentions — material junctions, lighting positions, special finishes — are executed exactly as intended.
Single Point of Contact
Our clients deal with one team, one contract, and one point of contact. No more being caught between a designer saying “the contractor should have done it this way” and a contractor saying “the designer did not specify it clearly.”
When Is EPC the Right Choice?
- Commercial office fit-outs where business disruption from delays is costly
- Restaurant and hospitality projects where design complexity and pre-opening timelines are tight
- Retail fit-outs where brand standards must be met precisely
- Multi-site rollouts requiring consistent quality across locations
- Complex renovation projects where engineering and design must run simultaneously

Frequently Asked Questions
Is EPC more expensive than traditional procurement?
The EPC fee incorporates a premium for taking on programme and price risk. However, the elimination of contingency budgets, change-order costs, delay penalties, and client management overhead typically makes EPC cost-neutral or more economical overall.
Can I still make design changes under an EPC contract?
Yes, via a transparent variation process. Changes are costed and agreed in writing before implementation. We encourage clients to finalise their brief thoroughly before contract award to minimise variations.
What size projects suit EPC delivery?
EPC is cost-effective from approximately ৳50L upwards. Smaller projects can still benefit from our integrated design-and-build approach under a simplified arrangement.
