Insight: Planning and scheduling: A guide to good practice

Good planning and scheduling are fundamental to managing time effectively on a construction project. Although closely connected, they perform different functions and, crucially, should happen in the right order. Good practice starts with developing the construction strategy first, before turning it into a detailed programme. 

Start with the Plan 

Planning is the strategic part of the process. It should involve the wider project team, including construction management, design, commercial and planning, because the decisions made at this stage ultimately shape how the project will be delivered. 

Before worrying about individual activity dates, the team needs to understand the job and agree the overall approach. How should the works be broken down? What construction methods will be used? How will the design and procurement strategies support construction? What needs to be subcontracted and when? 

There are also the practical interfaces to consider. Different trades need access to the same areas, design information needs to arrive before procurement can be completed, and materials need to be available before installation can start. Site logistics, work zones, access and resources all influence the strategy. 

Good planning therefore requires more than simply knowing how to use programming software. It requires construction knowledge, experience, communication and a degree of imagination. The aim is to arrive at an efficient and realistic delivery strategy that considers time, cost, resources, risk and opportunity. 

Build the Schedule from the Plan 

Once the strategy has been established, scheduling translates it into a time-based model. 

This is where the project planner takes the decisions made during the planning process and develops the detailed programme. Activities are given durations, responsibilities and resources, then linked together in a logical sequence. 

The scheduler also needs to consider contingency, preferred sequencing and float. The result should be a programme that explains not only when activities are expected to happen, but how they relate to each other. 

The important principle is that the programme should be the output of the planning process, rather than the place where the planning process happens. 

Trying to plan the project while building the schedule can lead to problems. It is akin to designing a building while simultaneously producing the detailed construction drawings. You can do it, but you risk developing the detail before the underlying strategy has been properly resolved. 

Good practice is to become familiar with the project first, develop an outline plan, establish the strategic plan and then work through the detailed methodology. Only then should that thinking be converted into the detailed schedule. 

Keep the Schedule Live 

Creating the programme is only part of the scheduler’s job. Good practice also means maintaining it throughout the project. 

A construction schedule should be a dynamic management tool that develops as the project progresses. It should be regularly updated using reliable progress information so that it reflects what has happened and provides a realistic forecast of what comes next. 

This becomes particularly important when things change. 

If an event delays or disrupts the planned sequence, the scheduler should identify its effect on other activities, available float, resources and ultimately the completion date. The project team can then assess possible recovery measures and understand the likely consequences of changing the planned sequence. 

Without a properly developed and regularly updated schedule, it becomes increasingly difficult to forecast when work will happen or understand the knock-on effects of delay. 

Super-prime projects

Planning and scheduling take on added importance when managing a super-prime development. These projects are typically defined by bespoke design, specialist craftsmanship, high-value materials and exacting expectations. The programme must therefore account for more than the sequence of construction works. It needs to reflect the design process, procurement strategy, client decisions and the standard of finish required.

Many materials, fittings and specialist packages will have long lead times or limited availability. Bespoke joinery, natural stone, specialist lighting and custom finishes may need to be designed, approved and manufactured months before they are required on site. Identifying these dependencies early is essential to avoid delays later in the programme.

The Project Manager also needs to coordinate a wide range of consultants, contractors and specialist suppliers while maintaining clear communication with the client. Design refinement often continues throughout the project, so changes must be assessed against the programme, budget and wider construction sequence before instructions are issued.

A strong schedule provides the structure needed to manage this complexity, but it must allow sufficient time for reviews, samples, mock-ups and quality inspections. On a super-prime project, achieving completion by a particular date is only part of the objective. The finished property must also meet the client’s expectations without quality being compromised to recover lost time.

Good Practice in a Nutshell 

The basic principle is straightforward: plan first, schedule second and then keep the schedule up to date. 

Planning creates the construction strategy. Scheduling puts that strategy against the clock. The software can calculate dates, logic and float, but it cannot replace the construction thinking that needs to happen first. 

When that sequence is followed, the programme becomes much more than a collection of dates. It becomes a practical management tool that can be used to monitor progress, anticipate problems, assess change and help keep the project on track from start to finish.
