LOCATION

CHARLOTTE APARTMENTS

80 CHARLOTTE ST

[1.01] Where is the site, what is the purpose of the building? Located in Fitzrovia near London’s West End, the site is bounded by four streets – Charlotte St, Howland St, Whitfield St and Chitty St. The building is multi-purpose, and the Site is split into 3 areas: 80 Charlotte Street (Commercial Block), The Charlotte Apartments (Residential Block) and “Asta House” (Residential Block).

In my Site Diary I will be focusing on researching about the Commercial Block Construction. There are 2 Main Entrances to 80 Charlotte Street, 1 VIP Discreet Car Entrance and 2 Alternative Entrances. The finished building will be partly refurbished and partly new build, with 30% of the original structures retained, including retained façade. The scheme is a major step forward the wider regeneration of the area and completion is expected in H1 2020.

Section 1.0

[1.02]

[1.02] How did the project originate? Who is the client? The client of this project is Derwent London. Their initial intent was to retain most of the Saatchi&Saatchi Block, but during the design stage it turned out that the structure was not stable enough, as the construction technologies have changed significantly from that time. Moreover, it was decided to dig down to increase the height of the building, so boundary walls were demolished except for the corner of the Charlotte Apartments, located in conservation area. The building previously belonged to LMS, but the company became merged with Derwent London. Client describes the former building as a “square donut with lots of buildings inside with different qualities”. In fact, there were a lot of extensions of different style and even some Vicrorian buildings.

SAATCHI&SAATCHI Saatchi & Saatchi is a global communications and advertising agency network, founded in 1970 and headquartered in London. 80 Charlotte Street has been the home of Saatchi & Saatchi London for more than 40 years since the year 1975, over which time the building has been the home of some of the most famous creativity. Now the building is in need of a makeover. Architects are transforming this set of 1960s, single-use blocks into a contemporary, fully integrated development of office, residential, retail and vibrant public space.

MY OPINION I reckon, that the concept was dictated by these prerequisites. Combination of various styles, textures, heights and qualities – this messiness gained its’ new reading in the new project..

VIABILITY

01 [1.04] What makes the project financially viable? How is it funded and why? The project is funded by Derwent London, who made it financially viable by smart use of space. Their intent was to clear the site of everything and make it super efficient. Inside the yard was a car park, which was replaced with a central core with staircases, lifts and toilets, it gave a way for spacious open-space office spaces around the core. Former building was around 200.000 square ft of space - this was incresed up to 380.000 square ft in a new building. The corner building is to become a residential building with 19 flats. Old building had a pretty terrible structure, so the planning application suggesting to increase the height of the building was submitted to the authorities. Levels G-05 will be 3 m high from floor finishing to soffit, Levels 06-08 2.9 meters high. For maximum use of height it was decided to lower the basement – every wall around the basement went deeper and beautiful lightwells appeared. Following this intent, all of the basement walls were to be rebuilt. So, the basement was digged out and the temporary structures, holding the ground around was put. That made a project 6 months longer to build, but 1,8 meters heigher. For the same reason of height usage, the ground level went down and the ramp was built, so now reception is lower then the ground. To earn money on residential block, 2 extra floors were built on top – now there will be penthouses.

PLANNING PROCESS & CONCEPT CHANGES

2008

The time scale of any project is never known exactly before the project start. Changings of the client’s plans changes the project’s parameters, which, in turn, changes the project time scale. The unpresicatable conditions may also take place. For example, they may be an underground water or any other weather conditions, which expand the time scale.

2010

Back to planning process

PROJECT START

Construction cost – a total amount that has to be paid for the man-hours and building materials in order to build a building.

In this project particularly, a high water table was detected while the construction, forcing main contractor to build the temporary drainage system.

2009

Structure not stable enough

Contract value (Contract sum) - is the price agreed with the contractor and entered into the contract. However, the contract sum does not constitute a ‘fixed price’ even if the contract is described as a fixed price contract, a lump sum contract or a guaranteed maximum price contract.

2007

First planning application

It is essential to tell the difference between the contract value and the construction cost.

Tender start

£220 MILLION

RIBA STAGE 3

The 1st contract period was August 2018, now the practical completion date is planned for 20 December 2019 with a small lead time till the end of February. Project timeline was dependent on several various factors. Firstly, planning applications took longer. Declined by the Committee, the project was forwarded for further jurisdiction to GLA to be supported by mayor – this took twice as much time. The second major issue was a 2 year pause in the project. The reason for that was that the lease for Saatchi&Saatchi was ending and their office should have been relocated to another Derwent’s building. However, Derwent needed to finish construction of that building first to put Saatchi there. Once it had been finished and Saatchi&Saatchi had moved, the work was resumed in 2014 with RIBA stage 3.

MY OPINION It is interesting, that it took only around 3 years to erect the main structure of the building. The rest of project time was deicated to the planning, changing of concept and tendering processes.

DESIGN &BUILD

Section 1.0

is a term describing a procurement route in which the main contractor is appointed to design and construct the works, as opposed to a traditional contract, where the client appoints consultants to design the development and then a contractor is appointed to construct the works.

Site Diary 15

[1.05.] Who are the key professionals and companies involved in the project? In this project the key companies could be split into 3 major groups: the Design Team, the Compliance and Monitoring Team and Subcontractors & Suppliers. It is not difficult to guess, that the DT designs, while the CMT monitors and checks for compliance. The DT consists of Architects, and Service & Structure engineers, and is usually appointed by the Client, but in this project particularly it was appointed by the Main Contractor. The quantity of Consultants increase with complexity of the project.

There is also a design co-ordinator or Project Manager. All the subcontractors were also appointed by the Main Contractor. However, Multiplex has a noncontractual link with the CMT, which means they can negotiate, but the members of the CMT are out of contractor’s control.

ARCHITECT

CLIENT

MAIN CONTRACTOR

In September 2007 Make was first appointed to work with this project. There was a small competition, but the choice has been done by the client long before.

Client wants this control of the development of the work, so they would rather prefer “Design and Build” contract type to a traditional one. Design and build can be seen as giving a single point of responsibility for delivering the entire project. Some clients, however, consider it is only appropriate for simple projects, where design quality is not the main consideration.

Multiplex was appointed in November 2014, as a result of a two-stage tendering.Before working on site the main contractor usually does risk estimating, as a huge of responsibility is transferred once the contract is signed.

Working in “Design and Build” conditions was uncomfortable for Make: a lot of documents, too many people involved, long confirmations and dependence on the contractor. From the architect’s point of view, reality is that sometimes contractor makes the decisions, which are not correct. Of course, traditional contract is of more preference for an architect, and “Design and Build” is better for simple projects, where the main contractor acts as an architect.

I was interested, which type of contract is of highest preference for each side of this project. I have asked whether they prefer Design and Build or not.

Multiplex would like to prefer “Design and Build” contract type, because even though they have most of risk, they can manage it and earn more money, so, in this case, risk becomes a profit. The contractor may use their own in-house designers to design the building, or they can appoint consultant designers, or the client’s designers can be employed by the contractor to complete the design (either by novation or consultant switch). In this project, apart from “Make”, there is an inhouse designer from the main contractor’s side and novated designer – “AFK”.

Site Diary 17

MAKE ARCHITECTS

MY OPINION I think it is rather convenient, that main architect has a laid-back position, while their project is being developed by 3rd parties, however, the quantity of drawings to review increases and sometimes it is more difficult to address the idea to other people rather then to draw it. The quality of design may fail.

“Make is a different kind of architecture practice. Founded by Ken Shuttleworth in 2004, we’re an employee-owned firm pursuing a democratic design process that values everyone’s input. Today we have more than 150 people in London, Hong Kong and Sydney providing architecture, interior and urban design services from concept to completion.”

[1.07] What is the architect’s appointment and role on the whole project? The way Derwent chooses architect is a very organic process. “Make” was appointed directly in the early stages and the Design process was a collaborative work with client. The contract type is standard RIBA. This architect has been designing the project until RIBA Stage 4, until the AFK has been appointed by Multiplex to take on the further development of the project.

[1.08] What is the architect’s role whilst the project is on site? Is it effective? Under the traditional contract there is no influence from the Main Contractor, Architect is the key professional in the project. The role of “Make Architects” in this particular project whilst on-site is to review the drawings from novated architect AFK and check their compliance with the initial design. Architects do their job rather effectively, even though only 3 people are engaged now.

DOCUMENTS FROM SUBCONTRACTOR

Here we can see a detailed drawing from Felix, which is the main facade subcontractor in this site. When subcontractor receives drawing from AFK, they start thinking how it could be produced in a way to comply with the architectâ&#x20AC;&#x2122;s guidelines. However, communication goes on. It may happen that initial requirements cannot be met, for example, due to the material size limits or lack of structural rigidity of architectâ&#x20AC;&#x2122;s design. In this case, subcontractor marks the drawings with revision clouds and comments and sends them back and the design process contines. Typical drawings usually have dozens of revisions, that is why to confirm one item it may take from several days to several years

MY OPINION I think that sometimes it is more efficient to meet and discuss the drawings, unless you have overseas subs, which was the case in this project. However, some tours were organised for prototype observation.

MEETINGS

TYPES OF SITE MEETINGS Every subcontractor has its Lead Pacakage Manager and Quantity Surveyor, they are in charge of coordination with Site Manager. All the Package Managers and also once Client’s representative are sitting in the Site Office for more efficient communication between the sides. The Main Point of Contract on site is Multiplex, which has most control over the Design Team and subcontractors.

WHAT HAPPENS IN A SITE MEETING? Different sides meet and discuss any problems or issues and propose the solutions. Site meetings provide a good opportunity for two-way discussions of any issues that have arisen or that are anticipated. Holding meetings on site enables the stakeholders to see progress for themselves, and to look at problem areas, discuss quality issues, assess mock-ups, and so on.

DAB (Daily Activity Brief) is the most important meeting on-site, attended by 30-40 people, all the representatives of subcontractors, trades and supervisors, currently engaged in the construction process. Every day there are 2 DABs: one for the Residential and one for the Commercial Project. Weekly Logistics Meetings with the trades are attended by Project Manager, Contract Manager, Site Manager, Off-site Manger and a Site Supervisor.

H&S Week (Health and Safety)is a big event, held by the H&S Advisor for everyone working on-site. Weekly Engineering Meeting is attended by 2 Engineers and 2 Site Managers either on site or in the office. Project Director leads all the Client facing meetings and also communicates with the major Package Managers. Design Meeting is one attended by the Site Manager and Project Leads from “Make Architects” and “AFK”. Main subcontratcors, like “Amery Construction” (concrete) and “Bourne” (steel) are allocated Weekly individual meetings. Internal Site Meeting is held every 4 days and is for Multiplex only.

Sometimes the contractor pays extras, if the architect should do any changes to the project. Derwent + Make: fee rate per month. Fee may go up or down depending on various conditions. In 2007 the client and architect could not agree for the certain fee, as the scheme of work has changed. It is a communicative process and always negotiation. Make prefers fee to be based on similar projects on site or based on the scope of work they have on other sites. Sometimes when the quantity of

The model of AFK is very strict: exact amount of people and time, fee agreed by emloyee’s wage. The more people is involves – the more money AFK earns.

[2.06] What is driving the project? The client’s biggest value is appraisal of the design. They are also interested in maximizing the assets in their portfolio, which also means money or new projects with new design value or both.

QUALITY

In Derwent’s case the project is never driven by one factor. According to the client’s opinion, the priorities for 80 Charlotte project were in the following sequence: quality, budget and the programme. Two questions Derwent is interested to know about are: “What will be the result?” and “Will this result be viable?”

[2.07] What are the penalties to the contractor if the project over runs?

SCOPE

There are 7 different stages and different penalties depending on the stage. In the last stage of completion, in case of delay Multiplex will be charged 243000 pounds every week since the time of completion date (December 2019). However, Derwent gives them one extra month to finish the works with an exemption from fine. This means, the final completion date is January 2020.

MY OPINION SLW

EMPLOYERS AGENT

D&C CONTRACTOR

I reckon that companies in the field of commercial building construction tend to have long-term partnership and are doing their job for decades, so it is not a problem for them to work efficiently enough on a new project.

I believe, that the Design Team has done a good job in competeing the design of a complex project and granting a planning permission. However, I guess it was rather challenging for the members of the Design Team to resume work after the period when the project was frozen for 2 years. Almost all representatives of the Constrcution Team who I was talking to during the site visits were relatively new to the project with a 10 years time scale, and I have not met anyone engaged in the project from its begining.

WORKFLOW

CLIENT

[2.08] What is the process and procedure for information and instructions going to the contractor? Is it efficient?

D&C CONTRACTOR

Official instructions are going on site through technical drawings marked “For construction”. The point of contract from Multiplex is their design manager, who negotiates with architects through on-line platform.

Contract design intent

[2.10] How does the Design Team share and Co-ordinate information and drawings? Is this efficient? Towards agreement there is a long approval process. In this project it is implemented through the Information Data Management.System, called “Acinex”. It is an on-line platform, in which every member of the Design Team has their personal accounts. Once the drawings are uploaded to programme, they are transmitted to QA Workflow.

ARCHITECT

Architect Coordintated design intent Drawing review Revision 00, 01, 02…

Information doesn’t come through once ususually, Drawing revew

the decisions are made through negotiations. There is a special CMT comments type between users.Comments may be A, B ,C, D type with, D – denied, A – approved. The hisory of comments is kept in the system, so that it would be easier to

analyze the data. Reporting delays via programme helps administering the process. Once the drawings receive A-A, they go to a final stage and are receive a stamp “For construction”. According to the diagram on the left, the whole process of approval should take 28 days. In real life it is longer then that, as it takes more one month to get A-A comments. The documents for construction may be reissued for 3 times The participants of the process would hardly call it efficient, as sometimes there can be up to 600 drawings to review for 1 person per month or 80 drawings to review for 1 person in a 10 day workflow.

Facade subcontractor Design responsibility

ARCHITECT’S OPINION METAL SYSTEMS

Specialist subcontractor

In a post-tender stage like this there shouldn’t be so many drawings to review The biggest problem is with residential buildings. Make developed design and AFK approved, but subcontractors said they couldn’t build this. This is the problem with bespoke items - may be 20 different arrangements of a single column and, of course, huge amount of information arising on the site. But people need quick answers.So it is quicker to use sketching in this process, however it is difficult to record that.

GOING DIGITAL

There are 2 kinds of mockups subcontractor makes – performance and visual, they are aimed to reduce risk of the client and contractor – the aim of the mockups [2.09] Are any Modern Methods of Construction, such as prefabrication, being utilised? There is a great use of DFMA and prefabrication in this project. By simplifying the design of a product it has been made possible to manufacture and assemble it more efficiently, in the minimum time and at a lower cost.

Pre-fabricated concrete plank - bottom side (ceiling)

Almost everything for this project was prefabricated off-site: concrete floor slabs, structural columns, beams, facade elements. The number of assembly operations was reduced to minimum with simple bolting joinery and assembly of two floors at a time. Two floors are connected with one module of column.

MY OPINION HAS CHANGED I have always thought that to build a complex building like this BIM technologies are mainly used. Contrary to this belief, in this project all drawings were made in CAD with the BIM used for reference for engineering and structure. The reason for this is that it is extremely hard to make a good output from BIM model because of its’ complexity, moreover there are constraints of creating BIM model of the existing building. Nevertheless, Muliplex uses BIM as a tool to coordinate works on-site.

QR for logistics and assembly

Intersection of primary structures with MEP were made possible with BIM. This allows to coordinate different services.

The prefabricated beams and columns of different types are also marked with unique codding to increase efficiency of construction.

ON SITE

[2.11] Identify how, if any, digital technology is influencing the progress of the site? As far as many elements in this building are prefabricated off-site, it is extremely important to distinguish them. QR codes contain a link to the inforamtion about every single beam, which can be found in a special system. The number of beam complies with its’ number in the technical drawing. It helps to track the production and transportation of beams, increasing logistics efficiency and allowing contractor to plan the works in case of delays. QR codes also help to assemble and maintain structure in future. [2.12] What opportunities are there for digital technology to influence site operations? The site is very technologically effective, so I could not spot any other opportunities.

INTERESTING There is also a crane anti-collision system, as the tower cranes are placed very close to each other. It is intetesing, that 3 vaults were designed to put the cranes during the constrcution process, they will be then dismantled.

QR for maintenance This yellow markings indicate the holes where MEP will come through. The condition of the holes is permanently reviewed and updated in the system.

PLANNING SECTION 106 AGREEMENT are private agreements made between local authorities and developers and can be attached to a planning permission to make acceptable development which would otherwise be unacceptable in planning terms.

[3.01] How did the project achieve Planning permission? Was it complicated? Normally this process takes place after the feasibility studies. Design team attends preapplication meetings to discover the preferences of the local authorities, submit the planning application, waits 3-18 months to get the decision.

Agreement for this project: - provide affordable housing - build a public pocket park

Planning notices

This one was unusual, because it went through a political committee. There were two applications for different blocks - a detailed planning application (reference 2010/6873/P), alongside an application for conservation area consent (reference 2010/6879/C). Both of them were submitted to the London Borough of Camden (LBC) on 17 December 2010. The committee has turned it down. Thereafter the application was taken to GLA (Greater London Authority), as it has the power to over-ride planning decisions made by the London Boroughs if they are

believed to be against the interests of London as a whole. To navigate through complexity of Camden planning requirements, an expert planning consultant “DP9” was hired. Applications were approved by the Greater London Authority (GLA) on 16 March 2012. Scheme currently on site was amended in 2013 and 2014. The Decision Notice accompanying the permissions included 20 conditions which need to be satisfied at various stages of the project. Current position is that 18 of the 20 conditions have been discharged. The owners of these conditions are either Multiplex or Derwent London.

[3.02] Look up the project on the Planning Portal and view the Planning Drawings – are they being strictly adhered to? Yes, the Planning Drawings are strictly adhered to.

Existing structure

Initial partial demolition intent

[3.04] How are the Building Regulations being dealt with, i.e. Approved Inspector, Local Authority, why was the particular route chosen? Building regulations were dealt with through an Approved Inspector consultancy – “BRCS”. It worked closely with design and construction team and provided the client with Building Regulation compliance and the mandatory certificates that they needed to complete the construction project. Generally, on this project building regulations were easy to deal with, the only exception was focusing more on fire requirements since the Grenfell Tower fire tragedy. One biggest issue was compliance with disability requirements, which was really a pitfall of working with existing buildings, trying to adjust old structure to new requirements.

In the center of the building there is an accessible central core, in which all the elevators, stairs and toilets along with the disbled WCs are placed. Lifts can accommodate wheel chair users or users who are not capable of using the stairs, taking them to each floor of the building. Wherever the toilet if placed, it is accompanied with adapted toilets to provide disabled users with suitable toilets, wash basins and grab rails for support.

The project if fully Life time home compliant. This means, that beyond the Building Regulations, which are not intended to provide the full standard of accessibility for disabled rather then making housing more accessible for visitors, a higher standard of 16 design features is met to ensure a new house will meet the needs of most households. For example, this includes wheelchair accessible WCs, easy access to windows, accessible for all sockets and many more.

Parking for disabled

The ground floor plan demonstrates that the entrances from the Charlotte St and Howland St are equipped with ramps and the Loading Bay has a safe route from the disabled parking bays.

PARTY WALL

Section 3.0

Site Diary 33

PARTY WALL AGREEMENT It is an act, which puts in place steps to safeguard the rights of those undertaking certain types of building work and the rights of their adjoining neighbours.

[3.07] Are there any Party Wall issues? Fortunately, there were no serious Party Wall issues, as it is an island site and almost all adjoining houses belong to the client.

This act is separate from planning permission or building regulation approval.

However, as 65 Whitfield Street has party wall there were some minor agreements, regarding scaffolding, crane rotating, access and construction boundaries, which did not take long. All the agreements were reached and can be reviewed at the Camden planning portal.

[3.08] If so how long did they take to reach Party Wall agreement? It only took several months to reach the agreements, however the other big issue was “difficult” neighbors, who were literally putting up roadblocks.

CLIENT’S OPINION Constant pressure from neighbourhood did some damage to the project budget. 2,5 million pounds were lost on complying with affordable housing requirement of 106 agreement and also 10-15 millions pounds of value was lost on creating Pocket Park.

CDM

[3.09] What is the project approach to CDM? Who is the Principal Designer and Principle Contractor? Are those persons that ‘create’ risk responsible for ‘managing’ that risk to the health and safety of others during construction, use and maintenance of the building? The CDM issue was managed by a subcontractor appointed by Multiplex, which is literally Multiplex’s other business. This 3rd party serves as both the Principle Designer and the Principle Contractor Even though the construction works have started long ago, the principal contractor still visits the site on a monthly basis.basis. The process of discharging the CDM issue is: Health and safety risk is labeled

and the risk goes to the CDM document, which is tendered. Thus, the main contractor is responsible for the risk they create themselves. ORSA is a CDM advisor of the project, but has bo obligations.

[3.11] In your view what are the key risks during the construction process and the eventual use of the building? Have all these risks been identified by the CDM team? Have you spotted any others? Visually/ graphically, how can you represent this? Cross link questions in this section with section 0.0 Formative Assessment/ Risk Assessment. I feel that the most dangerous risk on site may be a result of „competency failure” which can easily happen by mistake of one individual and lead to the increase of other health and safety risks. With all the hazards being monitored, however, if one individual

fails, there could be worrying results. An example of an easy competency failure, could be failing to remember to wear a hi-visibility jacket, which could lead to an accident.

THE CDM FLIPSIDE Sometimes CDM is used as an excuse by some sub-contractors when they do not want to produce the assigned scope of work.

The principal designer has responsibility for coordination of health and safety during the preconstruction phase, the principal contractor should coordinate the construction phase of the project.

MAIN CONTRACTOR

[4.01] Who is the Main contractor? How is the company set up? What are your personal thoughts on the performance of the main contractor? Multiplex is the Main contractor of the project Multiplex is an affiliated company of Brookfield, one of the world’s biggest asset managers. During my Site Diary Project I met mainly with Multiplex representatives and really liked the way everything was organised. The site was clean and the quality of construction works was just ideal. I was impressed to see such tidy construction site. It feels like Multiplex has high standards and gives a sense of performing beyond the expectations. [4.02] How was the main contractor selected for the project? Multiplex won a tender process, commenced in November 2014. The client was choosing between three main contactors - Bam, Multiplex and Mace, taking part in tender. There was a 2 stage tendering with the fee costs being specified at every stage. The pre-construction Agreement was signed first and then design information was sent for tender.

BROOKFIELD STRUCTURE

During the 1st stage a simple proposal has been received, and from that time a bigger package of design information has been calculated. The lumpsum fixed price was set. The overall construction cost was set at around 200 million pounds, including 5-6% for the job of Multiplex.

Two-stage tendering is used to allow early appointment of a supplier, prior to the completion of all the information required to enable them to offer a fixed price. In the first stage, a limited appointment is agreed to allow work to begin and in the second stage a fixed price is negotiated for the contract.

In the 2nd stage of tender the prices from the subcontractors and main contractor were confirmed and the Construction Phase has begun. Demolition had been done before the other packages were dealt with, as a measure to save time during cost estimation. fixed price. In the first stage, a limited appointment is agreed to allow work to begin and in the second stage a fixed price is negotiated for the contract.”

SUB-CONTRACTORS 01

Atrium render [4.03] Who are the specialist sub-contractors? There is a bunch of sub-contractors engaged in the project. The two main sub-contractors are Amery Construction and Bourne Steel – they are permanent “tenants” of the site and have their own works areas. Amery Construction produces precast concrete soffits, concrete walls, cladding and interior panels. Bourne Steel makes the skeleton of the building. Most of the site is at disposal of Amery team. Some of sub-contractors are located outside UK, i.e. Felix façade systems from Switzerland.

As an example, I would like to illustrate how the concrete slabs were designed and produced. Concrete slabs. Typical 6x1,5 m, they form a 6x9 m structural grid. Inside them there is a steel rebar for rigidity. Soffits are the finished products, as the concrete ceiling will remain exposed. In between they are sealed with 100 mm seam and in-situ concrete is poured on top to make the floor flat.

MY OPINION [4.08]â&#x20AC;&#x201A; WHAT DO YOU THINK ABOUT THE DESIGN OF THE BUILDING? WOULD YOU MAKE ANY CHANGES? AS FAR AS THE BUILDING IS LOCATED IN THE CONSERVATION AREA, I UNDERSTAND THAT THE ARCHITECTS WERE PRETTY MUCH RESTRICTED IN DEVELOPING THEIR CONCEPT. I LIKE THE PREVIOUS DESIGN PROPOSALS MORE THEN THE APPROVED PROJECT, AS THERE WAS MORE PASSION AND CREATIVITY IN THEM, BUT AT THE SAME TIME IT WAS A LITTLE BIT OUT OF CONTEXT. THE PROJECT WE SEE TODAY IS A BALANCED SOLUTION, SATISFYING DIFFERENT STAKEHOLDERS OF PROCESS. THE DETAILS THOUGH ARE RATHER GENTLE. THE BUILDING WILL NOT CAUSE TOO MUCH OF ATTENTION FROM THE WIDE PUBLIC, BUT WILL BE APPRECIATED BY SOPHISTICATED USERS. I WOULD PROBABLY MAKE NO CHANGES TO THE PROJECT, HOWEVER I WOULD WISH TO HAVE USED MORE CORTEN ELEMENTS IN IT.

CONLUSIONS AND THE FUTURE

[6.01] [6.03]

Section 6.0

Site Diary 57

CONCLUSION

[6.01]â&#x20AC;&#x201A; What have you learnt by following the site diary project on site? My site diary experience was excellent. I have been able to see the inside of the ongoing project of a city scale, gaining the insight into how the construction industry works and how the collaborative processes between different parties are organized. I was lucky to communicate with the representatives of leading UK companies, engaged in this project, as the job they are doing is really high-end. Apart from good management, I found out how the digital technologies increase the efficiency of the site operations and reduce the risk of the human factor to minimum. I was surprised to discover that a number of people in the office and on-site is relatively small, which demonstrates the efficiency of the operational management and great use of the technologies.

I have also rediscovered significantly the role of the Architect in this regard. Before the project, I assumed that the project management is the responsibility of the Architectural Team, but that was not the case, as the majority of work is done by the Main Contractor. I also thought that Architects execute the whole spectrum of works from the concept to design development with the weekly reissue of the blueprints and dozens of architects attending the construction site in turn, while, in fact, the supervision is made by only 2 architects and the technical work is deligated to other parties. I have extended my interest in pre-fabrication observing the changes it makes to the time scale and the accuracy of construction.

[6.03]â&#x20AC;&#x201A; How has the Site Diary experience informed your possible career direction in architecture? During the project I have realized that working on site appeals to me more then office . In future I will be searching for the project leading work

opportunities. The experience has also proved my interest in working in Make.
