(c) Explain whether or not the schedules agree. [4] In part (a) my answer does not include specific dates so the calendar week has not been considered, where the whole project takes 25 days in part (a), part (b) takes 33 days due to weekends not usually being working days. Task 4 for example, ‘construct garage’ takes 5 days in part (a) but the dates stated in part (b) in the Gantt chart and the task schedule show dates of 10 January to 16 January, which equal 7 days (inclusive), this is because the weekend of 12/13 January is added. Counting the working days and not the weekends from the 7 January to 8 February, which are the dates for the whole project in part (b), the days do amount to 25 as stated in part (a) of the answer. So, I would say that the dates do agree, as my builders are not going to work the weekends. The early and late start and finish dates do not seem to agree though. In part (a), apart from the critical path shown by the thickened arrows all the activities have some float time, but in part (b) the dates only give float days to task 7s ‘Damp proof course’ and task 14 ‘construct new stud wall’. In my scheduling I have left the required date blank so the software has not known when, at the latest, the task could be finished. If I enter a required end of project date of 8 February then the float days show properly in part (b) as shown in the task schedule below.

Question 2 [25 marks] (a) Identify precisely what resource is overloaded and over what dates. [8] The labour resource ‘Builder’, of which there is only one available, is used by more than one task concurrently and is overloaded as shown below in the resource histogram. The dates the Builder is overloaded are from 14 Jan 2008 through to 25 Jan 2008. The current task shown in criss-crossed red is ‘Build conservatory & extension’, if this were the only task for the builder then the resource allocation would fit but the builder has other tasks, such as ‘construct garage’, which makes the Builder resource overloaded.

(b) New Gantt chart with a levelled Resource Histogram. [9]
This has remained the same Original end of schedule 8th Feb New end of schedule is now 25th Feb – delayed by 11 workdays

This is now delayed by 20 workdays

This is now delayed by 8 workdays from 14th to 24th Jan and now has a float

Resource now levelled with no overloading Delayed

(c) Identify what method of scheduling has been employed. The method of scheduling employed is resource-limited scheduling where resources are limited but the finish time is flexible.√ From the start of the builder resource being required, there is only one eligible activity, task 4, as the other activities continue to depend on completion of one or more other activities. So task 4 is scheduled to start first. Task 4 then completes, releasing the builder resource. There are then 3 eligible activities, tasks14, 15 and 19. Again there is only one builder resource so only one activity can be scheduled. Rule one will now apply and allocate the builder resource to the activity with the earliest date for the latest start time, this is actually task 19 but you can see that task 15 has been scheduled to start next, this, I think is because it has the shortest duration and has another task to complete before the end of the project. Task 15 is scheduled.

Task 15 then completes, releasing the builder resource. There are now 2 eligible activities for the builder resource. Rule 1 applies again allocating the builder resource to task 19, which has the latest start time as task 14 has a large float time allowing greater flexibility. Task 19 then completes, releasing the builder resource and allowing the last task, task 14 to be scheduled next.

Question 3 [15 marks] (a) Stakeholder map [5]

Roofer

Letting Agents

Electrician Property renovation project

Garage Suppliers

Builder

Neighbours

Suppliers

District Council

Plasterer

DPC Company

Buildings Inspector
Key stakeholder relationships Stakeholder relationships

Painter/Decorator

Description of the stakeholders Roofer – supply and construct the roof for the new extension. Plumber – plumb in the new bathroom suite and central heating system. Electrician – rewire where necessary and change the sockets in the new bathroom area. Builder – construct the extension and make the necessary alterations to the property. Suppliers – supply materials for the builder. Plasterers – supply and plaster the walls where necessary. Buildings Inspector – Inspects the property at the appropriate times. Architect – has planned the renovation and needs contacting for any alterations. Letting Agents – will be notified when the property is ready for letting. 7

Garage Supplier – supply and erect the new prefabricated garage. Neighbours – hopefully will not protest against the extension/planning permission. District Council – planning permission will need to be granted by the planning department. DPC Company – used to install the Damp Proofing Course. Painter/Decorator – will decorate throughout once all alterations are complete.

The stakes of three of the stakeholders District Council – planning permission is critical to the projects room extension, without this planning permission there will be no extension and the project will fail. They need to be happy that the extension is in proportion to the original property and that there are no objections from the neighbouring property owners. In the past they have granted this style of extension to the neighbouring property. They are likely to accept this application, as it is a small extension. If the application is refused it will need to be redesigned and resubmitted. Builder – the builder is critical to the actual building of the extension and other alterations, without the builder nothing will progress and the project will fail. He needs to be happy that he is capable of doing the work, within time constraints and within budget. In the past he has carried out similar work. He is likely to complete the work and is flexible to alterations to the plan. He will communicate with me before he carries out any work not in the contract, as he is aware I will not pay for work not first estimated. Buildings Inspector – some of the work that the builder carries out is required to pass inspection by the buildings inspector. The work needs to pass inspection for the project to progress. The inspector wants the work to pass inspection and advises the best course of action. He has carried out many inspections before and our application is not unusual. He is likely to pass the building work, as the builder wants to stay on schedule and not redo his work. I will be onsite when inspections take place to be sure things are going right.

(b) Describe, predicted impact on the project of three stakeholders. [5] Roofer – the roofer has an essential role to provide the roof to the extension. Without the roofer building the roof, the new room will not be watertight and the other tradesmen, such as the electrician and plasterers won’t be able to do their part on time, which will delay the project. I would have predicted the impact on the project of the roof being built was very high, the roof could delay the project and the employment of the other tradesmen. The roofer is dependant on the weather and it is likely to rain through January and February when I need him and he will also have other projects to finish before starting mine. Electrician – the electrician is required to wire up the new extension and make other necessary changes. The electrician is needed after the room extension is watertight but before 8

the plasterers and plumber. I would have predicted that the impact on the project of the electrician would be medium. He can carry out the work at a variable time dependant on the roofer finishing the roof. The electrician is not dependant on the weather and there are only 3 days work, which can be completed over the course of 2 to 3 weeks. Plasterers – the plasterers will plaster the walls of the new extension and are nearly the last tradesmen before the finishing touches. I would have predicted the impact on the project to be low as this work will only hold up the painter and decorator, which is I and I have flexibility in my time.

(c) Three actions might take to ensure stakeholders in part (b) contribute to project success. [5] Originally the builder was going to construct the roof over the extension but now he is getting a roofer in to do the work. I will state to the builder that the roofer is his responsibility as he was not recommended to me and that the builder should not get his final payment until the roofer has completed a satisfactory roof. I will keep in contact with the electrician and the plasterers as to how far the project is progressing so they know exactly when they can come and install the new electrics and do the plastering. They do not want to turn up if the roof is not complete and the room not watertight. We will have prices agreed beforehand and put in writing so we all know what is expected. I will test that lights and sockets are working and that the plastering looks great and only pay each of them on completion of their work.

Matrix project structure

The matrix team structure has staff reporting to different managers for their work and training/development. Staff may be loaned from other projects and may be part or full time but report to two bosses. I do not think that this is the best organisation for my project as is not large enough to warrant two bosses and the project is not concerned with the staff members development and training. The various tradesmen are responsible to the headman of their branch and I approve the work on completion but a more suitable organisation may be the single team organisation. The project (single) team would have been a better structure. Although I am the project manager for this project, many of the team members have worked together before and worked well which is why they keep working together and recommending each other. Only their overall project managers change for each project undertaken. The overall builder who gathers and recommends the various tradesmen gathers his team together for each project he is employed for. He then has a close and reliable team, communication seems no problem and as I am now on site each day I am kept closely involved with the work any decisions to be made.

(b) Determine one-project team members’ motivations. [10] I have chosen the builder for this question and feel that the Maslow’s hierarchy of needs model most suites the builders motivations for this renovation project. I found him motivated to the project from the very start, as he was very keen to do the work. His physiological needs were already met in that he had his basic needs and brought his own food and drink to work with him, although I did make him a cup of tea each day. At first he worked out the price of all the work and a break down of all the prices so I could pick and choose what I would have done if I could not afford it all. I feel this gave him security in the fact that he would be paid for his work, as I was making sure I could afford it, a schedule of payments was also set up to ensure this. The area in which he was working was also a safe environment, as all the work was on the ground floor and there was nothing dangerous to do. This remained true throughout the project. As the project progressed the builder and I got on very well, he had many questions as to the intricate detail of the work and as the trust relationship grew I knew I could rely on his advice and he could trust me to make the right decision to make the very best of the project. Our relationship grew over the course of the project, as we began to talk to each other a lot more I found that we were not just employer and employee but we were also friends. I found that he was also a kitchen fitter and that he was very pleased for the extra work. The builder gained esteem from the neighbours and me as he progressed through the jobs and the work of the project. I have remarked on how well things are going and how lucky I am to have found him. This builder was recommended to me and I can now see why, his esteem grows as the project progresses and more jobs are completed. The builder did such an excellent job that he could only have been proud of the work. I told him on many occasions how happy I was with aspects of the work and how well parts turned out. I can only imagine his sense of satisfaction and self-fulfilment of having built something from nothing and to have a new room where once there was nothing. I think this selffulfilment grew as the work progressed and finished works could be gazed at and admired.

Question 5 [15 marks] One-page memorandum setting out the progress and status of your. MEMO From: Project Manager

To: Senior Manager

Subject: Renovation Project Sir

Date: 31 January 2008

The renovation Project is progressing successfully and within budget. All contractors have been selected, hired and prices confirmed. The garage and bathroom suite have been purchased, both under budget and confirmed to arrive on the 18th and 13th February respectively. The Damp proof course has also been installed and has already dried ready for the plasterers to start. The plasterers are due to start on the 11th February after the electrician has completed his work this week. The groundwork and drains have all been laid successfully and passed by the building inspector. These have been tested and covered over as if the ground had not been touched. No problems were encountered. The next stage is for the plumber to install the bathroom and he is confirmed to arrive on the 14th February. The foundations for the new extension have been laid and passed by the building inspector. No problems were encountered and the walls are to be built today if the weather permits. We are presently in discussion about not building the conservatory due to the more pressing matter of retiling the roof. The roof tiles are the original tiles and made from Chrysotile Asbestos with some of them moving in the high winds. It has been recommended to us to replace these and the quotes we have received are very reasonable, costing less than the conservatory, which could be built at a later date. In all, the project is progressing very nicely with no major hurdles and only the reroofing to make a big decision about. This will have to be decided before the roof to the extension is started which is around 18th February. I am very keen to re-roof with concrete tiles and build the conservatory next year when more funds may be available. J Taylor

Question 6 [10 marks] Word Count 2651 (Excluding the questions, references and diagrams) Project summary (from TMA01) The mission and role of this project is to renovate and modernise a recently purchased, run-down property into a comfortable, practical home ready for the letting market. This will create a second income for me and be a long-term investment. This is a real project with some work already carried out. The chimneys and chimneybreasts have been removed and I have employed the services of an architect who has drawn the plans for an extension and new room layout. These plans have been submitted to the council-planning department for approval. Work is continuing through this winter with the aim of completing the project in March 2008. I will be the project manager and sponsor, providing the resources for the project and ensuring the project progresses steadily to its successful completion within the time constraint. The champion of the project is the adjoining neighbour of the property, who is also my mother. The champion will keep a critical eye on the project, encouraging a swift completion of the property with a clean and tidy garden. I will also be the client and owner, responsible for purchasing all required services. I will be contracting the services of recommended builders and tradesmen. The project will involve employing the services of tradesmen to install a damp proof course, build the extension, rearrange some rooms in the property, build a bathroom, replace the windows and doors, erect a new garage, rewire the property, install central heating, plaster the walls and decorate. Simultaneous activities will include employing tradesmen while getting quotes for other works while checking all work is carried out to the specifications while investigating what needs doing next. There is a budget to this project with further funds available if something unanticipated occurs. There has already been a capital outlay when the property was purchased in March 2007. There should be a financial benefit at the end, shown by the property being valued on completion and comparing this with the initial cost price and any costs involved.
