Sectional Completion and Partial Possession

Large projects rarely complete as a single entity at a single moment. Hospitals hand over ward by ward. Retail developments phase their openings. The legal framework for phased completion has significant implications for LDs, defects liability, and insurance.

Key takeaway

Sectional completion and partial possession are distinct. Sections must be defined in the contract with their own completion dates, LD rates, and scope. Partial possession is a separate mechanism that reduces the LD rate proportionally. Informal partial possession — without the contractual mechanism — may not reduce LD liability at all. The administration must match the legal framework.

1. Why phased completion generates disputes

The problems cluster around two issues. The first is the interaction between sections and the LD regime: where the contractor completes some sections on time but is late on others, the employer must correctly identify and apply the LD rate for the late section while releasing retention and recognising practical completion for the completed sections. Applying the wrong LD rate — or applying LDs to the whole works when only one section is late — creates a financial dispute that the contractor will contest.

The second issue is the distinction between sectional completion, which must be defined in the contract, and partial possession, which may not be pre-defined. Partial possession of an area not designated as a section in the contract cannot reduce the overall LD liability unless the contract expressly provides for proportional reduction — which requires the Clause 2.33 mechanism in JCT or an equivalent in the applicable form.

2. Sectional completion — JCT and FIDIC mechanisms

3. Partial possession — the Clause 2.33 regime

Clause 2.33 of JCT SBC 2016 addresses partial possession: where the employer takes possession of part of the works before practical completion of the whole (with the contractor’s consent), the relevant proportion of retention is released, the defects liability period begins for that part, and the employer’s insurance obligation shifts for the taken-over portion. Critically, Clause 2.33.3 provides that the LD rate is reduced proportionally to the value of the part taken into possession.

The proportional reduction does not happen automatically. It happens through the contractual mechanism. Informal partial possession — where the employer simply starts using part of the building — does not engage Clause 2.33 unless the mechanism is formally triggered with written agreement on the date, area, and reduction value.

4. Practical application

For contractors

Ensure sectional completion dates, LD rates, and values for each section are clearly defined before execution. Where sections are not pre-defined, be cautious about agreeing to partial possession without first negotiating the proportional reduction of the LD rate. Always formalise partial possession in writing — the date, the area taken over, and the agreed reduction in LDs.

For employers

Ensure the contract clearly defines each section’s completion date, LD rate, and scope before award. Do not attempt to take partial possession informally — formalise it through the contractual mechanism to secure the correct legal consequences. Informal occupation may also have insurance-coverage implications that the employer does not want to discover after a loss event.

5. Risks and mitigation

For contractors, informal partial possession without contractual agreement on LD reduction may fail to reduce LD liability as expected. For employers, misidentifying the applicable LD rate for a section — or applying the whole-works LD rate when only one section is late — may create an overpayment position that the contractor will challenge, with costs recovery adverse to the employer.

Define all sections clearly in the contract, with their respective completion dates, LD rates, and scope descriptions. Use the sectional completion schedule to track progress, LD accrual, and retention release independently for each section. Formalise all partial possession events in writing on the day they occur.

6. Conclusion

Sectional completion and partial possession are powerful mechanisms for managing phased project delivery. They require careful contract drafting, disciplined administration, and clear communication between the parties. The financial and legal consequences of getting the administration wrong are significant — but avoidable with good practice on both sides.
