Colombo 05: Piling Before the Permit
A 14.5-perch lot fronts a 30 m wide road in Colombo 05, within the Colombo Municipal Council area. The client, a property developer, wants a seven-storey, 2,800 m² apartment building with 14 units. The planning submission has been refused: the council cites a parking shortfall (18 spaces required, 11 shown) and an inadequate rear setback from a 40-year-old three-storey house standing 2.5 m from the boundary. The client is bleeding interest on the land loan and instructs the architect to "release the piling drawings and let the contractor start piling next Monday - the permit will come, it's only paperwork". A piling rig is already on site, and the structural engineer has issued pile-cap drawings marked "for construction". The architect's appointment letter is silent on site supervision, and the fee for the whole project is 3.5 per cent of cost.
1. Is the client's instruction something the architect can act on? Set out the legal and professional position and how the architect should reply.
Read the worked answer
No. Piling is "development" in the ordinary sense - it is a building operation - and development within a local authority area requires a permit. A refusal means there is no permit. The architect who issues construction-stage drawings or a site instruction enabling piling is facilitating unauthorised development, and the council's remedy is a stop notice, and in a serious case demolition or prosecution of the owner and the person carrying out the work.
The professional position is separate and survives even if the council never notices. The architect is the person who prepared the drawings and released them. "The client instructed me" is a defence to a fee claim, not to a conduct complaint.
The written reply should do four things:
- State plainly that piling cannot begin, and that the architect will not release drawings for construction until a permit is issued.
- Point out the practical consequence the client has not costed: a stop notice leaves a partly driven pile field that cannot be built on, with the rig demobilisation and standing time on the client's account.
- Redirect the energy into the actual blocker - the parking and setback - and give a resubmission date.
- Record that the instruction was given and declined. Silence in the file will later be read as consent.
2. How should the design be changed to answer the two grounds of refusal, and what must be checked regarding the 2.5 m neighbour before any excavation?
Read the worked answer
The design changes should be driven by the refusal reasons, not by a general redesign.
Parking. The shortfall is seven spaces. Options, in order of acceptability: reduce the unit count from 14 to 11 (which cuts the requirement directly but costs revenue); use a mechanical stacker system, which can typically double the yield of a bay but needs 3.6 m clear height and increases the basement depth; or negotiate with the council over the parking standard if the site is genuinely within a public-transport catchment. The architect should model the stacker option first, because it preserves the unit count and the depth increase is a cost the client can price.
Rear setback. If the setback cannot be achieved by pulling the building line forward, the options are a reduction in height or footprint at the rear, or a stepped section that keeps the upper floors further back than the podium. Simply redrawing the line does not resolve it - the council will measure the same 2.5 m.
The neighbour. At 2.5 m, any basement or pile excavation affects the adjacent three-storey house. Before construction the architect needs a structural condition survey of the neighbour's building with dated photographs, a party-wall/adjacent-owner notification, a design for excavation support that limits ground movement, and a monitoring regime. This is not optional goodwill; it is the evidence that will determine who pays if cracking appears.
3. The client later asks the architect to sign the contractor's interim payment certificate for the piling, saying the council "won't check". What is the right course?
Read the worked answer
The architect should decline to certify and should say why in one short letter rather than a lecture. An interim certificate is a statement that work has been executed in accordance with the contract and, by implication, that the architect has no reason to believe it is unlawful. Certifying piling that has no permit is a false professional statement even if the council never opens the file.
The practical course is to decouple the two issues:
- Do not certify. Write to the client and contractor stating that no certificate will be issued for work carried out without a permit, and that the architect reserves the position on any subsequent instruction.
- Do not abandon the client. Continue the resubmission, and ask the contractor to hold the rig on standby only on the client's written instruction and at the client's risk. That keeps the architect inside the appointment while making the risk explicit.
- Check the appointment. Since it is silent on supervision, the architect should confirm in writing what site services are and are not included. Silence is where fee disputes and allegations of "you should have stopped them" both come from.
If the client insists on certification, the architect should decline formally and consider whether the appointment can continue. A fee of 3.5 per cent is not a reason to sign a document that misstates the position to a bank or a council.
