Site Possession & Access: Managing Delay, Disruption & Recovery

A short, practice-led course on one of the most fundamental questions in construction: when does the contractor actually have the site, and what happens when access is delayed, restricted, or taken back?

A programme can be carefully planned and resourced, yet still fail when the contractor cannot get onto the work areas needed to execute it. Possession is therefore more than a handover date. It affects sequencing, productivity, standing resources, disruption, delay, notices, and ultimately the employer's entitlement to delay damages.

This course develops a practical discipline for managing possession, access, obstruction, restriction, partial possession, and early use through the records and decisions that matter on a live project.

The Case

The course follows Trevelyan Civils, delivering a $26.8M freight interchange on a 64-week programme, with completion due on 30 June and liquidated damages of $12,000 per day, capped at $600,000.

The site is to be handed over in three sections:

• Phase 1 — Western earthworks: 2 May
• Phase 2 — Rail corridor: 30 June
• Phase 3 — Terminal: 15 August

Phase 1 arrives on time. Phase 2 arrives 42 days late, while a haulage tenant remains in occupation. Phase 3 slips by approximately three weeks.

Meanwhile, access continues to be affected by a shared corridor and western gate, including an 11-working-day embargo arising from a utility interface.

Later, the employer takes the apron and eastern road into early use—approximately 49 days before planned completion of those areas and representing around 22% of the works value.

The project eventually closes its account through abatement and reservations.

The challenge is to understand what each event means while it is happening—not months later when the programme and account are already in dispute.

Three Lessons

Lesson 1 — The Possession Obligation

Start with the fundamental obligation to provide possession. Examine date-certain and undisturbed access, what actually transfers at handover, possession certificates, handover discipline, performance-security gates, deferment, and the importance of a reliable possession log.

You will also consider how to proceed under protest when possession is incomplete or conditional.

Lesson 2 — Access, Obstruction and the Working Day

Not every access problem is the same. Distinguish denial, obstruction, restriction, and interface disruption. Learn to maintain working-day records and build an access-impact ledger that connects events to crews, plant, productivity, disruption, and cost.

You will use the case to price what a month of corridor restrictions can actually mean.

Lesson 3 — Partial Possession and Closing the Site

Examine what happens when different parts of the works are taken over or put into use at different times. Explore partial possession, early access, abatement, taking-over records, and the importance of reservations.

The final task is to build a close-out package that captures what was handed over, what remains disputed, and what rights have been preserved.

What You Will Learn

By the end of the course, you will be able to:

• Identify the contractual significance of possession dates and handover conditions.
• Distinguish access denial, obstruction, restriction, and interface disruption.
• Maintain useful possession and working-day records.
• Connect access events to programme, disruption, and cost.
• Manage sectional and partial possession.
• Assess the implications of early employer use.
• Protect notice and claim positions while work continues.
• Close the account with clear abatements and reservations.
