  • RIBA Plan of Work and Procurement Routes explained (part 2) – Partnering PPP and PFI

    Ferrovial Agroman has been contracted on the M8 in Scotland to develop the infrastructure, which can include projects such as hospitals, schools, roads, or prisons. This partnership involves a long-term investment from the private party to finance and operate the infrastructure, and may also include ‘soft services’ like catering and cleaning throughout its lifespan. This business model has been widely adopted globally, with significant success stories.

    The Private Finance Initiative (PFI) is a commonly used method for delivering infrastructure projects. It involves creating a separate entity, known as a Special Purpose Vehicle (SPV), which runs throughout the infrastructure’s life to receive payment from the public sector. A notable example is the M8 motorway project in Scotland, where Ferrovial will install tollboths and charge users after construction is complete, much like Cintra tollbooths across Europe, which are also owned by Ferrovial.

    In the UK, PFI projects account for the largest portion of infrastructure development. This model has gained popularity due to its ability to provide a stable financial return for investors while meeting the public sector’s needs for infrastructure development.

    The SPV used in PFI projects can consist of private parties, which may include:

    • Contractors
    • Facility Managers
    • Insurance companies
    • Banks and bonds investors
    • Equity investors
    • Professional advisors

    On the other hand, the public sector can also play a role in the SPV by partnering with private parties. This includes departments such as:

    • Department of Health
    • Department of Transport
    • Department of Defence
    • Local authorities (councils)

    According to the RIBA plan of work 2007, which illustrates the project flow from inception to completion, the process involves several stages. An extract of this is illustrated below:

          • The first action as a QS (Quantity Surveyor) when preparing a procurement strategy is to gather the client’s objective and requirement.

            These requirements should check off the client’s expectation on budget/financing, quality they are seeking to achieve, the duration of the project (or any time constraints) and any other risks they’d like to transfer.

            As per the RIBA plan of work, the brief is developed at Stages 1 and 2.

            According to a study by the Construction Management Association of America (CMAA), a thorough understanding of the client’s requirements is crucial in shaping the procurement strategy.

            The factors to consider from the client’s requirement include cost and financing, time, performance, and risk.

            Cost/Financing

            You will need to identify how the project is going to be funded and how much fund is available from the client at the moment.

            Certain clients require borrowing funds or obtaining board approval before taking on these projects.

            Time

            You will need to identify the required completion date or important milestone/key dates that a portion of the works needs to be completed by.

            Performance

            You will also need to identify the required functional performance of the development and an indication of the quality.

            For example, if the client is not bothered with the aesthetics, you may be able to look at just providing the works to a normal standard.

            Capital vs. Operational Costs

            You will need to identify the requirements over the running cost of a new development with the client.

            Risk

            You will need to identify from the project brief the level of risk or planning required for the project.

            For example, if you’re building in a city centre, you may need to consider additional requirements for traffic management and design restrictions.

            In the context of the Latham report, risk transfer on contract type is a crucial aspect of procurement strategy.

            The report illustrates that even when it comes to contract options, the more the contractor is involved and the less the client provides, the more risk they undertake.

            This is evident in the risk transfer on contract type, demonstrating the importance of understanding contract options and risk implications for effective procurement.

            The visualization provided by the report allows for a clearer understanding of the risk transfer and its impact on the procurement process.

            Moreover, the Latham report’s content highlights the significance of contract options in mitigating risk.

            The report’s focus on risk transfer on contract type underscores the importance of considering the types of contracts and their respective risks.

            By analyzing the contract options and their associated risks, clients can make informed decisions about their procurement strategy.

            The visualization of risk transfer on contract type in the report provides a valuable reference point for future reference.

            In addition to the risk table, the report also provides a valuable table highlighting the advantages and disadvantages of various procurement routes.

            This table enables clients to compare different options and make informed decisions about their procurement strategy.

            By analyzing the pros and cons of different procurement routes, clients can identify the most suitable option for their needs.

            The table’s visualization provides a clear and concise representation of the advantages and disadvantages of each procurement route.

            Furthemore, the report emphasizes the importance of considering the benefits and drawbacks of different procurement routes.

            The visualization provided by the report underscores the need for a thorough analysis of each option, considering factors such as time, cost, and performance.

            By taking the time to understand the advantages and disadvantages of each procurement route, clients can ensure that they make the most informed decision for their project.

            This report provides a comprehensive introduction to the NEC and its concept, including project bank accounts.

            The report explores the application of project bank accounts in the context of the NSW government’s Inquiry into Construction Industry Insolvency.

            For those interested in exploring this topic further, the NSW government’s website provides additional information on the Inquiry into Construction Industry Insolvency.

            However, it appears that the report is no longer available on this website.

            Fortunately, a valuable archived copy of the report has been made available.

            To summarize, the three main factors that affect the procurement strategy are time, cost, and performance.

            Understanding these factors is crucial for making informed decisions about the procurement options.

            The report emphasizes the need for a thorough analysis of each procurement route, considering the factors of time, cost, and performance.

            By making an informed decision, clients can ensure that their project meets its objectives.

            Cautionary Note: The report discussed above does not cover all aspects of CDM regulation procedures and requirements.

            Clients should be aware of these requirements throughout the planned works, as they may be crucial for the project’s success.

          • One tool for Quantity Surveyors to record your work log and measure your productivity

            To maintain optimal energy levels, it’s essential to address deficiencies in certain nutrients. B12 plays a crucial role in the production of energy, and deficiencies can lead to fatigue, weakness, and shortness of breath. Research from the National Institute on Aging (NIA) suggests that B12 deficiency affects approximately 10% of the population, particularly the elderly. Maintaining adequate B12 levels through diet, supplements, or medical treatment can help mitigate these effects.

            CoQ10 is another essential nutrient for energy production, helping release energy from food and balance my energy levels throughout the day. While CoQ10 can be expensive, research published in the Journal of Clinical Biochemistry and Nutrition found that supplementation can improve energy levels and reduce fatigue in individuals with CoQ10 deficiency.

            In addition to supplements, certain external stimuli can also enhance energy production. Binaural tone therapy, a non-invasive audio technique, has been shown to increase alertness and reduce stress levels. Research from the University of Edinburgh found that binaural tones can improve cognitive function, memory, and mood by distracting the brain from internal chatter and promoting relaxation.

            To maximize the effectiveness of binaural tones, it’s essential to use them consistently and in conjunction with other energy-boosting strategies. For instance, using a white noise app like Mind Wave for 10 minutes can help create a conducive environment for focus and productivity. Continuous use of focus sounds can further enhance mental clarity and reduce distractions.

            • How to Become a Successful Property Developer

              INTRODUCTION:

              Are you a property developer? Here is a quick guide for people just like you. This will introduce the processes involved in property development in detail. The purposes of this guide are:

              (a) To explain the principles of construction involved in property development.

              (b) To help you become an expert building surveyor and avoid mistakes.

              PROPERTY DEVELOPMENT:

              First, you have to learn the basics of property development. Property, or real estate, development is a business in which developers buy lands or older buildings to build new structures on, or to renovate old ones with the intent of selling those to various buyers. It does involve a high risk. Developers have to pay attention to the needs of buyers and the present market demands during construction of an estate. The key works done by property developers are:

              (a) Purchasing a piece of land.

              (b) Determining the market value of the property.

              (c) Developing the building design.

              (d) Getting approval by the local building authority.

              (e) Building the structure and managing the construction carefully.

              (f) Selling it at a good profit!

              Developers have to work with many different people at each level of the process including engineers, city planners, various surveyors, contractors, leasing agents, inspectors, and many others.

              In the United Kingdom, development is defined in the Town and Country Planning Act of 1990, s55, as “In this process building, mining, engineering, and other operations as carried out over or under land.”

              Many real estate investors are now showing an interest in getting involved in property development. They buy pieces of land or old houses, tear them down, and then build a number of new townhouses, apartments, or other improved buildings. Then they sell them and move on to the next project. But the process is not as easy as it may sound. You must travel a long road on the way to reaching your desired goals when you choose to pursue property development as a serious career. There are a lot of procedures involved that you must learn and become familiar with. Below are explanations of some of them:

              MARKET FOR OPPORTUNITIES IN PROPERTY:

              The price at which a property or piece of land would sell for in an auction is called the “market value” of that property. Sometimes the term market value is used interchangeably with “fair market value” and “open market value.” The definition of market value may change depending on different circumstances.

              In cases of property development, market opportunity is a great benefit to you. Real estate markets are considered to be both transactional and informational. In these markets, you must remember that you should make your profit in the process of buying a property rather the process of selling it. So, you make your money when you buy, not at the time you sell. If you are seeking to improve your economic future, you really might want to consider taking an opportunity like this.

              There are two ways to make money through property development. One is rental yield, or rental income growth, and the other is capital growth. Rental income is the money paid by the tenant. Rental yield is essential if you plan on a buy-to-let strategy.

              RETURN ON INVESTMENT:

              When selling estates or properties, it is highly recommended that you need to aim for a minimum of 30% return on your investment.

              Suppose the property cost £400,000 and the net rental income is £20,000. This simply means that the net rental income is £20,000 divided by £400,000, which is equal to 0.05 or 5%.

              SOURCE OF FINANCING TO GET THE PROPERTY:

              Financing is key for property builders. To be successful, you need to handle finances properly when dealing with each project. Maintaining good credit and being aware of available financing sources are crucial. Sometimes, you may need to apply for a loan to meet necessary expenditure costs. Keep a record of all financial documents and associated paperwork.

              Property developers have many options to raise funds. There are various sources for acquiring the moneys you may need. Some of the more basic options for you to choose from are:

              There are over 14,000 commercial banks, representing the biggest financial brokers directly involved in providing funding for real estate businesses.

              Commercial banks primarily offer a multitude of loans and approve financial assistance for permanent purchases on occasion.

              Most large commercial banks have a real estate loan department involved with property developers.

              Big commercial banks are nationally chartered or state chartered, with the U.S Controller of Currency overseeing federally chartered banks.

              Nationally chartered banks can make residential loans up to 90% of the estimated value, but not for more than 30 years.

              On the other hand, state chartered banks are supervised by various agencies of the particular state they are in.

              Developers who don’t meet commercial bank criteria can obtain funding from finance companies.

              Finance companies arrange consumer loans for durable and non-durable goods and make real estate mortgages.

              Finance companies: Developers who don’t meet all the commercial bank criteria can obtain funding from finance companies. One of the tasks of the finance companies is to arrange consumer loans which will allow for the procurement of both durable and non-durable goods. Types of investments made by finance companies are different from those of commercial banks. Their investments frequently include real estate mortgages, while commercial banks prefer to be more involved in granting personal loans.

              Savings & loan associations: With regards to their total assets, S&Ls are not actually the biggest financial operatives, like commercial banks are. But, they are the principal authority on acquiring financing in terms of real dollars. Usually, they are the fundamental suppliers of permanent financing for single-family, owner-occupied, residential properties. S&Ls also frequently offer investors’ loans and loans for home improvements, most notably those for industrial or commercial properties, general real estate, and apartments. Savings and loan associations may be either nationally or state chartered. Roughly 60% of all S&Ls are state chartered while the remainder are nationally chartered.

              (d) Private funds:

              Practically 80% of any development project’s cost is often financed by lenders. Private funds, from non-commercial sources, are referred to as ‘hard money.’ Private lenders are essential for those not approved for loans by commercial banks or S&Ls. A significantly larger cash endowment is necessary for project success.

              (e) Life insurance companies:

              Insurance companies provide capital financing for property development. Approximately 1,900 insurance companies worldwide lend money through local mortgage brokers or bankers. They often back larger-scale projects.

              Life insurance companies

              Insurance companies play a vital role in providing capital financing for property development. Approximately 1,900 insurance companies from all over the world lend money using local mortgage brokers or bankers as intermediaries. They normally choose to back the larger scale projects. No federal agencies oversee the insurance companies. Instead, they are all state chartered, and nearly 90% of all those insurance firms are stock-based companies.

              Mortgage bankers

              Mortgage bankers are often seen as individuals who only provide mortgage loans. They make these types of loans by utilizing their own assets or moneys acquired temporarily from another lender. Such packages are purchased by primary lenders as well as secondary investors.

              Like many S&Ls and commercial banks, mortgage bankers are also state chartered.

              On occasion, it may be necessary to seek financial help from a lender. Such transactions are typically managed by a mortgage banker.

              Such events may make it difficult to release the loan to a third party for review. This is a much more appealing option for investors, as the risk of losing their capital is greatly decreased.

              Mortgage bankers are engaged in both commercial and residential financing as well as participating in other enterprises.

              These other enterprises include performing appraisals, offering investment counseling, and writing hazard insurance policies.

              Mortgage brokers are generally concerned with enterprises similar to those of mortgage bankers and commercial banks. Mortgage brokers are not the principal contributors of capital. Their role in the development of means to secure financing, however, is crucial. Mortgage brokers regularly strive to bring borrowers and lenders together for the sole purpose of ensuring the availability of financing for a multitude of projects. When looking for a broker, be sure he or she is well-qualified in the field and possesses a reliable network of wholesale lenders. It is a must for brokers to maintain a list with all the data on the lenders and documents associated with a job that can be referenced whenever necessary. Mortgage brokers are not routinely involved in the providing of a loan when it is made and the matter is ended.

              GETTING AN ARCHITECT:

              A person who designs buildings, directs the plan, and, in many cases, supervises the actual construction of the project is termed an architect.

              They are employed by the developers to design the layout, appearance, and construction of new buildings.

              On behalf of the building authority, they may also execute the building contract and certify the completion of the job.

              In cases of refurbishment, a measured building survey of existing structures is required.

              Building surveyors and, in some cases, architects, may be contracted for this task.

              Basically, they are responsible for securing approval of the plans for the project’s undertaking.

              In such cases, planning consultants are not required.

              Normally, architects are paid their requested percentage of the total building cost.

              It is important to employ an architect in the earliest stages of the project.

              You should only contract him or her after learning his or her efficiency level, track record on past projects, experience with jobs similar to yours, and reputation in the field.

              To maximize your profits in this sphere, an architect can really help a lot.

              So, you need to make sure you are hiring an expert.

              The cost for their services is generally calculated as being 10 to 15% of the total building budget.

              GETTING A CONTRACTOR:

              A contractor is a person who makes a promise in writing to perform the work needed to build an estate or structure.

              They are employed by the property developer to create a development scheme.

              A contractor’s primary objective is to make a financial profit.

              Developers have to hire some contractors for some of the construction works in order to obtain a complete and improved building.

              Some development companies appoint their own contractors.

              Residential developers tend to employ those expert in building residences; they are called house-builders.

              Developers may keep their contracting division at arm’s length as an entirely separate profit-making centre, though there has been a common trend toward a more integrated approach.

              Builders have to take an additional risk related with any development project.

              When a builder is hired only to be the contractor, the financial profit is related only to the building cost and the length of time of the contract.

              Generally, in the building development process, contractors have to carry out many specific activities in order to reduce the risks to the developer and to maximise the commitment of the other workers to the job.

              Therefore, an efficient developer should ensure the capacity and capability of the contractors before beginning the proposed work and seek the right balance between the lowest-priced proposal and the quality of performance.

              A licensed contractor is required for all property development projects.

              If a contractor is unregistered, you may be facing some serious problems, because workers’ compensation insurers’ requirements for maintaining safe working conditions, such as those mandated by WorkSafeBC, may not be maintained.

              So, hiring a registered contractor is not only essential, it is critical.

              A contractor is a person who makes a promise in writing to perform the work needed to build an estate or structure. They are employed by the property developer to create a development scheme. A contractor’s primary objective is, obviously, to make a financial profit.

              QUANTITY SURVEYOR:

              According to different opinions, the origin of this type of surveyor and the work he or she does, is the ancient Egyptian civilisation.

              The Egyptians used to compile estimates and costs of building their magnificent structures.

              Quantity surveyors are the key professionals in this industry.

              Often, they are also known as cost managers, cost engineers, estimators, project cost controllers, project coordinators, cost analysts, and so on.

              They usually work in the building industry and concern themselves with construction costs, products, and the contracts.

              Quantity surveyors provide expert advice on building costs.

              Developers, architects, building proprietors, and governing bodies are their main clients.

              16. Advise on best methods and sources of procurement.

              Before starting any project, a calculation of budget is done by a quantity surveyor on the demand of the clients. He or she has to ensure that the budget is sufficient for each step of construction after estimates have been generated. When construction starts, the quantity surveyor should keep the cost within the proscribed limits. He or she can provide cash flow data so the client can arrange finances needed for each stage of the project. One of the duties of a quantity surveyor is to provide the bank with a project report and to help the client by preparing a draw down certificate for the bank loan. The surveyor is in charge of adding up the total cost when the construction is completed. A quantity surveyor can prepare a statement of final account which shows all records of costs of every section and stage of the project.

              Structural engineers and engineering surveyors are employed to work with the architects and quantity surveyors to advise them on the design of the construction elements of the estate or building.

              They may also take part in supervising the actual construction stages of the project.

              Engineering surveyors are even more exceptional than their fellow engineers.

              Because not all engineers are licensed, you have to make certain the ones you hire possess this accreditation.

              You can also hire engineering surveyors for other types of survey work including topographical or measured building surveys.

              Topography is studied using various methods, including trans-stadia surveys, photogrammetry, remote sensing, aerial and satellite imagery, and radar and sonar.

              To design the layout and location of buildings, roads, or any other construction, a topographic survey is essential. Consider consulting Icelabz Solutions Limited, a company that provides valuable support services for these surveys.

              MEASURED BUILDING SURVEY:

              A measured building survey provides a detailed representation of a building’s structural elements. This type of survey includes floor plans, roof plans, cross sections, elevations, reflected ceiling plans, and wire frames.

              The measured building survey is a crucial step in designing and building structures. It involves capturing 3D data of buildings and other structures using the latest laser-scanning techniques.

              This is a correct representation of your building showing all the structural elements. You have to get an engineering surveyor to undertake such a procedure for existing properties. The measure building survey includes floor plans, roof plans, cross sections, elevations, reflected ceiling plans, wire frames, and the like. The latest laser-scanning technique utilises this survey to capture 3D data of buildings and other structures.
