AEDO Construction OPC, PRC-licensed civil engineers who design commercial buildings nationwide and design-and-build them in Negros Oriental. This guide describes the actual sequence a project follows, not a marketing simplification.
Short answer: a commercial building moves through nine stages — site and feasibility, concept design, detailed architectural design, structural design, MEPFS design, permitting, bidding and contractor selection, construction, and inspections leading to turnover. None of these stages is optional, and skipping ahead on any of them (usually starting construction before the design is finished) is where most owners lose the time they were trying to save.
Owners who have built a house before assume a commercial project is the same process at a bigger scale. It isn't. A commercial building carries more disciplines that have to agree with each other before a shovel goes in the ground, a heavier permitting load, and a bidding step that a single-family house usually skips. Here is the sequence as it actually runs.

Project Phase Timeline Estimator
A planning-level timeline split across the nine phases below, scaled to your building's size and whether it needs a full bidding process. This is a planning range, not a schedule commitment — LGU processing time in particular varies by city and cannot be guaranteed by anyone.
Read this as a planning range. Design timelines compress with a decisive owner and expand with every round of "what if we changed this." Construction duration scales with crew size and material lead times, which this tool does not model precisely — treat the construction figure as the roughest of the estimates here.
The Nine Phases, in Order
1
Site selection and feasibilityConfirm the lot's zoning classification, check for easements/setbacks, and run a rough cost-versus-budget sanity check before spending on design. A geotechnical investigation belongs here too if the site or soil condition is unfamiliar — deciding foundation type after design is finished is expensive to undo.
2
Concept designThe architect translates the brief — floor area, function, budget ceiling — into a massing and layout the owner can react to. This stage is meant to be cheap to change; that's the point of doing it before detailed drawings exist.
3
Detailed architectural designFloor plans, elevations, sections, finish schedules, and enough detail for the structural and MEPFS engineers to start their own work against a fixed layout.
4
Structural designFraming system, foundation design, member sizing and computations, sealed by a registered civil/structural engineer. This has to react to real decisions from architecture (column grid, floor-to-floor heights) and feed real constraints back to MEPFS (where beams can and can't be penetrated).
5
MEPFS designMechanical (HVAC), electrical, plumbing/sanitary, and fire protection systems, sized against the architectural layout and coordinated against the structural framing. See our design coordination guide for where this stage typically clashes with the other two.
6
PermittingBuilding permit application under PD 1096 and its IRR, plus any ancillary permits the project triggers — fire safety evaluation, electrical/sanitary permits, and a locational/zoning clearance from the LGU. This step runs on the LGU's schedule, not the design team's, and is the single most common source of a schedule that overruns before construction even starts.
7
Bidding and contractor selectionFor projects run through formal bidding, this stage packages the complete drawing set into bid documents, evaluates contractor proposals, and results in a signed construction contract. A direct-negotiation project skips the multi-bidder comparison but still needs a scope-and-price agreement before mobilization.
8
ConstructionSite mobilization through substantial completion — sitework, foundations, structural frame, envelope, MEPFS rough-in and finishing, in that general order with real overlap between trades.
9
Inspections and turnoverFinal electrical, plumbing, and fire safety inspections, then the Certificate of Occupancy application under PD 1096 Sec. 10. Turnover to the owner follows occupancy approval, not the other way around.
Figure: Overlap, Not a Straight LineStructural and MEPFS design run in parallel, not one after the other — but only once architecture has fixed the layout they both design against. Permitting can start once drawings are substantially complete, before every last coordination detail is closed.
Where Timelines Actually Slip
Three patterns account for most of the delay we see on commercial projects that come to us mid-trouble:
Construction starting before design is finished. An owner under pressure to break ground authorizes site work while architectural details are still moving. Every later change then either gets built wrong or forces rework — both cost more time than waiting would have.
Permitting time left out of the schedule entirely. LGU processing time varies by city and by season, and it is not something a design team or contractor controls. A schedule that assumes permits appear instantly is not a schedule, it's a hope.
Mid-construction design changes. A layout change requested after materials are ordered and framing is up doesn't just cost the new work — it costs the demolition of what's already built and the delay while everyone re-coordinates.
Where a Formal Bid Fits
Not every commercial project needs a multi-contractor bid — a smaller project with a trusted contractor relationship can move straight to direct negotiation once the design is complete. Bidding earns its extra time on larger projects where price competition and contractor qualification genuinely matter, or where the client's own procurement policy requires it.
AEDO's role outside Negros Oriental. Nationwide, AEDO runs the design phases of this sequence — architectural, structural, electrical and sanitary/plumbing — and provides remote construction oversight of a contractor the client hires locally: progress checks, quality checks, cost tracking against the approved budget. In Negros Oriental, AEDO designs and physically builds the project in-house, start to turnover.
Frequently Asked Questions
How long does a commercial building project take in the Philippines, from concept to turnover?
There is no fixed number — a small commercial fit-out can turn over in a few months, while a multi-storey building with a full permitting cycle commonly runs 12 to 24 months from the first feasibility conversation to turnover. The variables that move the timeline most are how fast the design gets finalized without mid-project changes, how long the LGU takes to process permits, and whether the contractor's schedule is realistic to begin with.
Can construction start before the building permit is approved?
No. Under the National Building Code of the Philippines (PD 1096) and its IRR, a building permit must be secured before construction begins. Some site work — clearing, geotechnical investigation, fencing — can proceed under separate permits, but structural construction without an approved building permit exposes the owner to stoppage orders and the professionals involved to liability.
What causes the most delay in a Philippine commercial building project?
In practice, three things account for most slippage: starting construction before the design is fully finalized, mid-construction design changes requested after materials are already ordered, and LGU permit processing time that wasn't built into the original schedule. All three are avoidable with a realistic upfront timeline and design discipline before ground-breaking.
Does AEDO build commercial projects outside Negros Oriental?
AEDO designs and builds commercial projects directly in Negros Oriental. Outside that province, AEDO provides the complete design package — architectural, structural, electrical and sanitary/plumbing — plus remote construction oversight of a contractor the client hires locally. AEDO does not claim to physically construct buildings nationwide.
