Cash Flow in construction industry presents an aspect of utmost importance for the cost planning of the project. It is essential that project managers deal also with the project accounting, in collaboration with the accountant. Cash flow is an ongoing process, in which the project manager must cope with all the payment costs, through cost projections, during the construction lifetime of the project, trying to avoid cash shortfalls. Especially, in construction industry, the cash flow management is critical due to retainage, change orders and delays. Due to a successful cash flow management the project manager, together with the other parties, has to set project milestones and achieve that the project will be cash positive in these specific milestones. This procedure leads not only eventually in the efficient operation of the construction works and the on-time deliverable of the project, but also help a company grow its business. In this wiki article, the questions of what cash flow is, how it has to be managed and what project milestones are and how they have to be set, are going to be presented in this wiki-article.

[edit] Introduction

[edit] Client Cash Flow

The cash flow sets out when costs will be incurred and how much they will amount to during the life of the project. Predicting cash flow is important in order to ensure that an appropriate level of funding is in place and that suitable draw-down facilities are available. Until the main contractor has been appointed, cash flow projections are likely to be based only on agreed fee payment schedules for consultants and a simple division of the construction cost over the likely construction period (or perhaps an allocation of construction cost over an s-curve distribution). It is only when the main contractor is appointed, a master programme prepared and some form of payment schedule agreed that cash flow projections become reliable. Cash flow projections may be affected by the need for the early purchase of long-lead time items or by items that the client may wish to purchase that are outside of the main contract (such as furniture or equipment). Supply chain cash flow

Cash flow is also an issue for the construction supply chain, and is a common reason for contractors and sub-contractors becoming insolvent. This can be catastrophic for a project in terms of time and money. It is in the client's interest therefore to ensure that the supply chain is paid promptly. The government suggest that, 'Historically, it is has not been unusual for lower tier supply chain members to have to wait for up to 100 days to receive payment, which damages their cash flow and can harm their business.' Ref Cabinet Office, Project Bank Accounts – Briefing document. A number of measures can be adopted to improve payment and so cash flow in the supply chain, including: Fair payment practices. Construction supply chain payment charter. Project bank accounts. In addition there are a number of remedies for late payment.

Cash flow is an issue of utmost importance for the client. It represents the timeline of the incurred costs for the project not only during its construction, but also during the life cycle of the project. In other terms, it is the inflow of cash to the contractor form the client, which is necessary for funding the project. The client

[edit] Cash flow estimation

A cash flow projection is a business tool of utmost importance for the construction industry, providing a basis for controlling one or multiple projects. The cash flow projection of the project execution team implies whether the project can be funded throughout its whole construction timeline, avoided undesirable events, such as budget shortfall, which maybe in some extreme cases may lead the contractor to bankruptcy. Cash flow estimation is closely related to construction time, as it is a dynamic procedure where project cost meets the project schedule. ^[1] A cash flow forecast (also called a 'cash flow budget' or 'cash flow projection') helps identify whether a firm needs to borrow, how much, when, and how it will repay the loan. Building a cash flow forecast allows an evaluation of cash resources that are required and when they are required by. Business owners can identify likely future gaps in funding and plan for those gaps accordingly. It is a vitally important tool for predicting the continuing financial health of the business. Additionally, cash flow models enable business owners to assess 'what if' scenarios by changing key variables to see how vulnerable the business is to price changes, staffing levels, exchange or interest rate movements, and other key drivers. In larger organisations the cash flow projection can be integrated with day to day operations. This can help identify what production is necessary, what resourcing is required and can provide an assessment of the capacity within a business.

[edit] Payment methods and milestones

The project payment methods have to be clearly defined in the contract and describe the exact terms of the transactions between the stakeholders. The contracts, naturally, affect the cash flow of the construction project, as they can describe different payment methods, specifically for one particular project. Especially, if the client pays for the project at the project completion, the contractor have to search funds from the start to the delivery of the project. Some typical payment methods are ^[2] :

• Payment on completion. However, this type of payment is not usual in construction industry
• Advance payment. This is the opposite when the client pays in advance some amount of the payment
• Milestone payments. Payment is made on the successful achievement of a project milestone. The milestone payment can be an agreed percent of the total value or a percentage according to the phase of the project. With the word milestone, it can be the payment is based upon progress in completing on what it has been agreed between the client and the contractor. These type of payment based upon achieving defined percentages of a contractor’s programme of activities is also called as a ‘planned payment’ scheme.

In construction projects, the identification of the major milestones of the construction process is often the major tool for managing the schedule ^[3], and consequently the managing of the budget of the project. Finally, the payment between the suppliers and the contractor usually take place after the delivery of the service. ^[3]

[edit] Cash flow vs expenditure

[edit] Uncertainty in cash flow

The final cost of successful construction projects is usually well estimated and it does not overrun the available budget ^[1]. However, the actual expenditure during a specified project milestone may vary from the estimated cost at that time of the construction schedule by a large amount. This is due to the fact that the cash flow projections may differ from the accounting calculations due to a number of factors: ^[1]

• The Project managers are quite optimistic and are more based on the overall cost estimation of the project proposal
• The client delays his payments milestones due to disagreements and, generally, aggressive contract negotiations with the contractor, resulting eventually in decreasing the amount of the inward cash flow.
• Bureaucratic collisions and limited managerial capability of the contractor can result in delays, concerning the assembling of the invoice supporting documents.
• Delays due to the invoice approval cycle by the client
• Delays in the equipment and the materials of the construction project
• Changes in materials and prices due to rapid inflation ^[3]
• Contingency events and errors in the design process

[edit] Cash flow estimation with BIM

A unique value of this prototype is dramatically automating the time required to generate cash flow analysis. Traditionally, contractors could spend weeks performing the quantity takeoff, scheduling, cost estimating, and cash flow analysis. This prototype offers a method that can produce a cash flow in minutes. Architects will often propose multiple designs, each represented by its own 3D model. With this technology, contractors would be able to quickly compare cash flow scenarios for each model, which would be potentially useful for value engineering decisions and bidding strategies. Contractors who are considering bidding on multiple projects would be able to quickly perform cash flow analysis for each project and determine which one has the best possibility to earn the highest profit margins. The contractor could then focus its resources on preparing bids for only the most profitable projects.

Payment to a contractor in a series of lump sums, each paid upon his achieving a ‘milestone’ – meaning a defined stage of progress. Use of the word milestone usually means that the payment is based upon progress in completing what the promoter (client) wants. Payment based upon achieving defined percentages of a contractor’s programme of activities is also known as a ‘planned payment’ scheme.
