Introduction


Building projects are invariably continuums, whereby decisions taken at one stage will impact on future issues which arise. Furthermore, building projects depend on the interaction of various members of a team in order to be successful (Smith, 2004).

A project requires complicated assessments, evaluations and decision making and performance throughout the project from inception through to completion.  The probability of successfulness is highly dependent on the suitability of these decisions and actions in relation to the characteristics of the project. These decisions can affect the efficiency of the project, the cost of the project, the party who is liable for certain risks and numerous other significant features of the project.

The objective of this project is to examine a number of key stages within the Hertfordshire School of Construction building project and arrive at decisions and/or define vital elements of the project which are deemed most suitable.  

Any decisions reached is done so by Alpha construction Ltd through regular meetings to examine and discuss the options that are available to the client at each stage and evaluate their suitability before reaching a group decision on the methods of performances that should be used or the elements which should be included in the project along with supportive evidence or research.

Theme 1 Summary of Decisions



Theme 1: Agreed Decisions


Theme 1 is concerned with are the establishment of the parties involved in the project, the selection of the procurement system used and the nature of the production information which will be used in the project.

Method of Procurement

In essence procurement is the amalgam of activities undertaken by the client to obtain a building (Frank, 1990).  

It is generally accepted that there are three methods of procurement currently practised in this country. The traditional or conventional approach, in which at least in theory design and construction are seen as separate elements; , which implies a more integrated approach; and management, by which either the client or a contractor assumes the central management responsibility. However, there are in addition many variants, hybrids, or compound versions of these methods (Cox, et al, 2003).

Which procurement method is likely to prove the most appropriate in a given situation will depend upon the nature and scope of the work proposed, how the risks are to be apportioned, how and where responsibility for design is to be placed, how the work is to be coordinated, and on what price basis the contract is to be awarded (Cox, et al, 2003).

Selecting the most appropriate procurement path is largely a matter of determining which performance requirements head the client's list of priorities.

These might include:

a) Technical complexity;

b) aesthetics/prestige;

c) Economy;

d) Time;

e) Exceptional size or complexity involving input from numerous sources and/or to satisfy several users' requirements;

f) Price certainty at an early stage in the project's design development;

g) Facility for the client to change/vary the works during the project's construction stage.

Traditional / Conventional procurement system is adapted for the project.

Procurement using traditional methods

In the traditional approach, the client accepts that consultants are appointed for design, cost control, and contract administration, and that the contractor is responsible for carrying out the works. The responsibility of the latter extends to all workmanship and materials, including work by sub-contractors and suppliers. The contractor is usually chosen after competitive tendering on documents giving complete information. However, the contractor can be appointed earlier, either through negotiation or on the basis of partial or notional information.

The traditional method, but using two stage tendering or negotiated tendering, is sometimes referred to as the 'Accelerated Traditional Method'. By this variant, design and construction can run in parallel to a limited extent. Whilst this allows an early start on site, it also entails less certainty about cost.

Watch points

  • A traditional lump sum approach requires the production of a full set of documents before tenders are invited. Adequate time must be allowed for this.
  • The traditional procurement method assumes that design will be by appointed consultants, and it does not generally imply that the contractor has any design obligations. If this is to be the case, for example with specialist sub-contract work or performance specified work, express terms should be included in the contract.
  • Because the client appoints consultants to advise on all matters of design, and cost, he thereby retains control over the design and quality required.
  • There is certainty of cost, to the extent that a lump sum is known before work begins, even if it has to be adjusted during the construction period as provided for in the contract.
  • The contractor depends heavily upon the necessary information and instructions from the architect being issued on time. There is a risk of claims if they are delayed.
  • Information release dates are sometimes agreed beforehand, but making these contractually binding can cause problems.
  • The client may decide which specialist firms the contractor is to use, although the contractor will require certain safeguards relating to performance.
  • All matters of valuation and payment are the responsibility of the client's consultants.
  • If it is impossible to define precisely the quantity or nature of some of the work, it is still possible to adopt a traditional method on the basis of approximate quantities, provisional sums or cost reimbursement. However, this is a less than perfect solution: the fuller and more accurate the information, the nearer to the relative safety of the lump sum approach.
  • There are widely accepted codes of procedure for single stage or two stage tendering, whether competitive or on the basis of a negotiated price. These should be used whenever possible (Cox, et al, 2003).

Characteristics of the system

  • The system has operated in Britain, the Commonwealth and other parts of the world reasonably satisfactorily. It has stood the test of time.
  • It is understood by most clients and they know their financial commitment when they accept the builder's tender, if the design has been fully developed at time of going to tender.
  • The architect has considerable freedom to conceive and develop the design without excessive time or economic pressures, provided the cost ceiling is not exceeded and the client's requirements are generally satisfied.
  • The project cost can be estimated, planned and monitored by the quantity surveyor from inception stage through to completion of the project.
  • The system makes it possible for the architect to introduce consulting engineers, landscape architects and other experts to advise on or design 'sub-systems' of the project.
  • The architect is able to consult specialist contractors and suppliers who he believes to be appropriate for the project or who manufacture and/or install components for sub-systems which would be compatible with the system as a whole at design stage, with a view to nominating them subsequently as sub-contractors or suppliers for the project.
  •  Sub-contractors may be invited to submit competitive tenders to the architect for the sub-system in which they specialise, thus ensuring that the most economic price is obtained.
  • Drawings and bills of quantities provide a common basis for competitive tenders from selected main contractors.
  • In the event of the client requiring the project to be varied during the course of construction, the bills of quantities contain prices for items of work which may be used to adjust the contract sum to take into account ( Frank, 1990).

Contractual Arrangements

The contractual arrangements are simplified in respect to the client as he only needs to enter into contract with (Figure 1): In the traditional approach, the client is in direct contractual relationship with the consultants on the one hand and the contractor on the other. Any contractual links for sub-contracts will be between the contractor and the firms in question. Only where the client makes nominations is it advisable to recommend collateral agreements to safeguard his interests in respect of any matters which might lie outside the building contract.

Figure 1.  Contractual relationships: traditional procurement (Cox Et al, 2003)

Parties involved

In this system the main parties involved from inception to completion are as follows:

  • Client
  • Employer’s Agent (Consultants)
  • Main Contractor
  • Subcontractor (Dom 1)
  • Subcontractor (Dom 2)

Client         

The client, in this project  is effectively the most important party as not only is he the instigator of the project, providing the need to build, he is also the financier of the works and employs all of the parties involved (Smith 2003).  The client is constantly involved with the project and is regularly informed on the progress of the works through his independent consultant and the main contractor.

Employer’s Agent

Hertfordshire School of Construction Ltd should appoint consultants be involved and so to help him with executing the project successfully the client will appoint an Employer’s Agent who will provide the client with independent advice and guidance.  The main role of the employer’s agent is to provide the client with impartial advice if and when it is required, assist the client in preparing the employer’s requirements and supervise the progression of the contractor’s work to ensure they comply with the contract.  Further, the performance of some of the client’s responsibilities in the contract is passed to the employer’s agent.  However he does not have the power to decide on issues between the parties named in the contract i.e. between the client and contractor (Turner 1995).

The employer’s agent is a firm of specialists consisting of:

  • Professional Engineers, Architects Quantity Surveyor: To assess the financial aspect of the project, To assess the design aspect of the project
  • Clerk of works: Represents the employer’s agent and the client and supervises the work of site along with the contractor’s site manager.

Main Contractor

The main contractor is expressed to be the next main party involved in the project as they are appointed to  the project.  The employer’s agent will advise the client on one contractor who is mostly likely to be capable of carrying out the project and the employer’s requirements is submitted to the chosen contractor to tender for.  If the client approves of the cost and design the contractor has submitted he is awarded the contract.

The main contractor will contain an in house design team consisting of the following specialists:

  • Quantity surveyor: To deal with the financial aspect of the work
  • Architects: To design the building
  • Structural Engineers: To design the building
  • Building Services Engineers: To design the building services
  • Public Health Engineer: To accommodate features complying with public health standards.
  • Interior Designers: To design the interior and deal with the turnkey aspect of the procurement system
  • Planning consultants: To deal with obtain planning permission and achieve other regulatory compliance

The main contractor will also have an in house building team consisting of:

  • Site manager: Responsible for the day to day running of the site and overseeing all operations.

The contractor will have the flexibility of appointing subcontractors for services which he does not have in house.

Subcontractors (Dom 1)

With  DOM 1 subcontractors are those which provide resources that are not involved with the design of the building.  DOM 1 subcontractors are:

Subcontractors (Dom 2)

The sub-contractors (Dom 2) are involved with some aspects of the design work and are appointed at the scheme design stage to assist the main contractor in designing the project.  DOM 2 subcontractors are:

  • Roof specialist: To design the steel roof.
  • Structural engineers: To provide further structural advice.
  • Building Services Engineers: To deal with the heating, lighting, plumbing, sanitation, telecommunication, ventilation, fire precaution, lift and refuse disposal systems.
  • Foundation engineers: To design and construct appropriate concrete pad foundation.
  • Window specialist: To design and install the windows.

Other parties

Other parties which may take part in the project are insurance firms whom, insurance to the work, site and various other insurance is taken out from.  Another party involved is the local authorities planning department who are responsible for granting planning permissions and inspecting work to ensure it complies with the relevant building standards.  

Project Stages

The client is involved from the commencement of the project and will initially appoint his independent consultant i.e. employer’s agent.  Together the two parties will progress through the inception and strategic briefing stage, where with the two stages are combined.  During this period the employer’s agent will carry out a site survey using his in house land surveyors to access the feasibility of constructing on the site. In addition the employer’s agent will advise the client on the choice of a contractor who is most capable of handling such a project as well as compiling the Employer’s Requirements report which is sent out to the contractor for them to tender for.

The Outline Proposal/Contractor’s Proposal stage is where the contractor is now bought in via an invitation to tender from the client and will assemble his contractor’s proposal with the help of his design team and building team and his quantity surveyor who will value the works and submit a tender price.  The employer’s agent and client will then proceed to analyse the suitability of the submitted proposal.

The client, employer’s agent and contractor are then involved in the next stage of the Contract Sum Analysis where the actual price for the work has to be agreed on by the client and contractor.  When this stage is completed the contractor is officially appointed to .

At Scheme Design stage the contractor and his DOM 2 subcontractors will be involved to develop further the proposals devised in the previous stage.  At the end of this stage the employer’s agent and client is involved once again to review the scheme and analyse whether it meets the client’s requirements.  

Once the design has been approved the contractor and DOM 2 subcontractors continue to finalise the design in the Detail Design stage.  Again when the stage ends the employer’s agent will again assess the design with the client.  When the design is approved by the client the Production Information stage proceeds.  Where the contractor, DOM 1 and DOM 2 subcontractor are involved to produce the necessary production information required.

The Contractors Quantities stage will involve the contractor’s quantity surveyor who will be responsible for producing the bills of quantities; he and the employer’s agent’s professional quantity surveyor will both then price the works.  The priced quantities are compared by the employer’s agent professional quantity surveyor to ensure the prices are accurate and not exaggerated.  The results of which are reported back to the client so that he is informed on the progress of the works.

At the project planning stage the contractor, DOM 1 subcontractors, DOM 2 subcontractors and the suppliers are involved to plan the production of the works.  The local authorities planning department is also involved to provide the timetable of when the works should be inspected.  During this stage the employer’s agent will oversee the plan and again report back to the client.

During the Construction to Practical Completion stage the contractors building team, DOM 1 subcontractors, DOM 2 subcontractors and suppliers are fully involved to construct the building.  The contractor’s site manager is responsible for managing the operations on site.  Throughout this stage the employer’s agent will supervise the construction process and the contractor will often report to him who will in turn report back to the client.  In addition the client may make several visits to the site to establish how the work is progressing.

Production Information

Production Information is concerned with all information which contributes to the commencement, development and completion of the project.

Employer’s Requirements

The initial document is considered to be the Employer’s requirements which is the basis for an invitation to offer since the document is sent to the contractor whom they  must respond to in order to win the contract.  The employer’s requirements contain the following information:

  • The client’s requirements on the Building block he requires
  • A report containing details of the site survey.

Contractor’s Proposal

With the contractor having analysed the Employer’s requirements they will respond by producing a contractor’s proposal.  The proposal will contain details on the general approach to layout design and construction (Smith, 2004).  From this document which is submitted to the client, he should be able to deduce what the contractor proposes for the Hertfordshire School of Construction Ltd project.  Since no traditional form of tendering will take place this document is required by the client to assess whether this contractor is suitable to execute his project.

Contract Sum Analysis

Since the client and contractor must negotiate on a contract price, this is done so through the Contract Sum Analysis.  This contract sum analysis is a break down of all the probable costs involved in the project, both the client and contractor along with the employer’s agent will discuss and agree on a cost for each section.  This will build up to form a fixed price contract.

The amount which should be reserved as a contingency sum will also be discussed and agreed upon.  Such a sum is used to fund the expenditure of items of work which were reasonably unforeseeable at the design stage; the sum however is not used to fund to pay for design variations except with the approval of the employer.

Production Information

Once all details regarding design and construction has been finalised, the production information concerning the building is required. These documentation can be vaguely categorised into three sections; drawings, schedules and written documentation.  Drawings are supplied in the form of schematics layout and elevations and are used to assist the client as well as other professionals to understand the work to be performed.  

The drawings are also necessary to gain planning permission and building regulation approval and required by the construction team of the main contractor in order to plan and construct the work.  Additional visual aids will ...
