First 90 Days on a Major Project

BUILDIT major-project entry playbook

Enter the project without pretending to know it. Build orientation, trust and control before you try to change it.

An onboarding and internal-transfer playbook for reading a major project’s contract, controls, people, legacy issues and informal operating system without creating early political or commercial mistakes.

Manual 09 · Commercial & Contracts Soft Skills Series The First 90 Days on a Major Project

How to Enter, Read and Become Useful to a New Team · 16-page practical manual.

Clarify the mandate, boundaries and immediate risks before the project starts defining them for you.

Obtain the role mandate, reporting line, current phase, key project documents, delegations and immediate priorities. Ask what cannot wait for normal onboarding and avoid forming private conclusions from one person’s handover.

01

Confirm the role

Clarify the package, reporting line, authority, expected outputs and what success should look like by Day 90.

02

Request the core documents

Head contract, key subcontracts, forecast, risk register, programme, delegations and organisation chart.

03

Identify urgent exposure

Ask which decisions, time bars, stakeholder commitments or distressed packages cannot wait.

04

Set boundaries

Confirm confidentiality, approval pathways and where your ability to analyse ends and delegated authority begins.

Do not arrive trying to win the project argument before you understand the project.

The first task is orientation: what the deal requires, what the team believes, what the records support, which decisions are live and where the project has already spent trust.

The organisation chart shows accountability; the first month reveals who actually carries context and influence.

Map the people who approve, explain, challenge and move work. Major projects run through formal reporting lines and a second network of technical history, credibility and access.

Project leadership

Strategy, client commitments, enterprise exposure and final decision routes.

Commercial

Forecast, claims, variations, procurement, authority and inherited positions.

Delivery

Sequence, constructability, access, package reality and current pressure.

Design and planning

Releases, critical path, records, baselines, interfaces and future constraints.

Finance, legal and procurement

Cash, reporting, advice, market exposure, security and governance.

Client, consultant and subcontractors

External authority, influence, relationship history and delivery dependencies.

Map more than names and titles.

Formal roleWhat are they accountable and authorised to do?
InformationWhich history, evidence or technical context do they carry?
InfluenceWhose judgement is trusted when the answer is unclear?
Engagement routeHow and where should the relationship be built?

Listen widely without joining a faction.

Major projects accumulate history. Treat complaints as information requiring corroboration, not as an invitation to inherit another person’s enemies.

Meet each critical function and ask what they need from your role.
Acknowledge prior work before proposing change.
Do not promise an outcome before understanding authority and evidence.
Give credit for inherited strengths as well as naming gaps.

Do not administer clauses in isolation from the deal the project priced and the strategy it is pursuing.

Read the scope, exclusions, qualifications, design responsibility, time, payment, change, security, insurance, dispute and approval pathways. Then compare tender assumptions with the current forecast, cash position and delivery reality.

Contract and strategy

Understand the governing terms, the assumptions that won the work and how the project intends to protect or recover its position.

Time barsMaterial notice and response obligations.
DelegationsWho may recommend, approve and commit?
ExposureBooked opportunity, known downside and settlement strategy.
Inherited positionEvidence-based conclusion or repeated narrative?

Numbers and control

Reconcile forecast, commitments, accruals, variations, claims, cash, contingency and risk. Focus first on large movement, ageing items and assumptions without owners.

Separate evidenced recovery from optimism.
Trace cash certified, collected, retained and disputed.
Identify unlet scope and remaining market exposure.
Test whether each risk has a value, owner, trigger and mitigation.
ForecastMovement, optimism and unsupported recovery.
CashCertification, collection, retention and dispute.
ProcurementUnlet scope, market pressure and commitments.
Claims and variationsAge, evidence and decision pathway.
RiskOwner, value, trigger and mitigation.

An inherited narrative is not an inherited fact.

List the issues that repeatedly return to meetings: ageing claims, incomplete notices, unresolved instructions, weak records, disputed baselines, authority gaps and relationships already under strain.

Ageing claims and variations

What remains undecided, why has it stalled and which evidence gap actually prevents resolution?

Notices and time bars

Which urgent rights, responses or contractual steps are exposed by delay?

Instructions and scope

Where is work proceeding without clear authority, valuation or responsibility?

Records and baselines

Which accepted narratives are unsupported, disputed or impossible to reproduce?

Relationship strain

Which issues have become attached to status, trust or previous failed attempts?

Governance history

Which matters are settled, reserved or constrained by decisions made before your arrival?

Separate confirmed fact, inherited opinion and unresolved assumption.

Ask who has already tried to resolve the issue and what stopped it. Do not casually reopen settled matters; understand the governance and relationship history before turning old uncertainty into a new problem.

Commercial consequence follows the construction sequence.

A package can be contractually contained and operationally central. Understand the critical path, design releases, access, possessions, commissioning, client dependencies and where delay or scope ambiguity can move between packages.

01Walk the work with delivery and planning staff.
02Identify the critical and near-critical interfaces.
03Trace design releases, access and third-party dependencies.
04Connect notices and claims to programme evidence.
05Name milestones with external or political consequence.

Read the interface before you judge the package.

The commercially important question is not only who owns the clause. It is how design, access, sequence, procurement and adjacent work combine to create or contain the project consequence.

The fastest route to trust is clear authority, update rhythm and no-surprise behaviour.

Agree the current priorities, decision boundaries, review standard, escalation thresholds and evidence that will define a successful first 90 days. Your manager should provide clarity and backing; you should provide early warning, ownership and reliable closure.

Top three priorities
Delegations and approvals
Update rhythm and format
Immediate escalation triggers
Review standard
Day-90 success evidence

Read their scoreboard.

ResultsCost, margin, cash, programme, claims, quality and safety.
ControlAccurate forecasts, early risk and no preventable surprises.
PeopleTeam output, development, retention and succession.
ConfidenceWhether senior management and the client trust their area.

Make the relationship work.

Give early warning before the manager has represented the old position upward.
Bring consequence, options, a recommendation and the decision required.
Learn what they need, in what format and how often.
Close loops and confirm when agreed actions are complete.
Expect usable feedback, appropriate authority and support above your level.

Resolve something useful enough to matter and contained enough to understand.

An early win should close an ageing issue, improve visibility, remove uncertainty or establish a reliable operating rhythm. It should demonstrate control without claiming ownership of work completed before you arrived.

TEST 01

Material enough

The outcome should remove a real source of delay, uncertainty, exposure or repeated management attention.

TEST 02

Contained enough

You must be able to understand the evidence, authority, stakeholders and consequences before acting.

TEST 03

Respectful of history

Acknowledge prior work, identify the remaining gap and avoid presenting inherited progress as your own.

TEST 04

Repeatable control

Prefer a result that also establishes a clearer record, rhythm, owner or decision pathway for future work.

Example: close the ageing variation without reopening every argument.

Identify the two remaining evidence gaps, arrange one focused review with delivery and the client representative, and move the assessment through its decision pathway. The early win is not theatre; it is visible control and respect for prior work.

Each checkpoint should convert new understanding into clearer ownership and fewer unknowns.

Day 30 establishes the map and urgent controls. Day 60 tests relationships, assumptions and operating rhythm. Day 90 confirms the stable mandate and the next capability or recovery priorities.

Day 30 · Orientation

Map the system and contain urgent exposure.

Understand the team, contract, commercial position, programme, reporting rhythm and the few issues that cannot wait.

Evidence: people map, contract priorities, initial commercial scan and urgent-risk list.
Day 60 · Ownership

Test assumptions and operate the agreed rhythm.

Own defined workstreams, corroborate inherited narratives, build cross-functional relationships and show reliable escalation and closure.

Evidence: active workstream ownership, tested assumptions, operating update rhythm and an early win progressing.
Day 90 · Control

Confirm the stable mandate and what comes next.

Record credible contributions, remaining uncertainty, the responsibility you are ready to carry and the next development or recovery priorities.

Evidence: closed or controlled early win, agreed ongoing scope, review feedback and next-step plan.

The aim is not to know everything by Day 90.

It is to know what matters, where the evidence sits, who carries authority and context, what remains uncertain, and which responsibilities the team can now trust you to hold.

Ten connected chapters from pre-entry preparation to stable ownership at Day 90.

Before Day One
Map the Formal and Informal Team
Read the Contract and Commercial Strategy
Read the Cost Report, Cash and Risk Register
Find the Legacy Issues
Learn the Programme and Critical Interfaces
Establish the Line-Manager Operating Agreement
Build Relationships Without Joining a Faction
Create a Credible Early Win
Days 30, 60 and 90
Closing position The first ninety days should produce orientation, trust and control—not a performance of instant certainty.
