Bloomberg London wins 2018 RIBA Stirling Prize

The multi-award winning European headquarters for Bloomberg in London designed by Foster + Partners has won this year’s RIBA Stirling Prize, the UK’s most prestigious architecture award.

The ‘astounding’ and ‘boundary-pushing’ project was unanimously chosen by the RIBA judges for its achievement in the level of research, innovation, experimentation during the design process.

The project occupies 102,190㎡ of land, designed as two-buildings connected by a bridge over a re-established ancient Roman arcade. The exterior features hand-crafted sandstone, and over 97 types of bronze window fins. A few of these fins incorporate built-in air vents. The building houses a distinctive 210m long bronze ramp, designed as a place of impromptu conversation, meeting, and connection.

Kikukawa, as metal-craftsmen and engineers, worked closely with the project’s Stirling Prize-winning architect Foster + Partners, contractors, and other suppliers to ensure the vision, the world’s most sustainable office, was delivered. As the bronze supplier, Kikukawa provided the FURUMI (sulfurized) bronze panels, from the fins to the ramp, each displaying our metal craftsmanship and technology.

Within Kikukawa, our 3D designing technology, our cutting-edge welding technology (FSW and fiber laser welding), and the artisanal FURUMI (sulfurized) finish played a fundamental role in the realisation of the project.

The project and the collaboration ‘have not just raised the bar for office design and city planning, but smashed the ceiling’ said RIBA president Ben Derbyshire.

It is a privilege for Kikukawa to have contributed to this monumental project. Congratulations to Foster + Partners for this great achievement and your continued success.

Extra Large Mirror Polished Stainless Steel Panel

Kikukawa has the expertise to provide extra large high-quality mirror polished stainless steel panels. The following pictures are from the quality inspection conducted on a mirror-polished panel over 1500mm(W) x 5000mm(L), its high-quality and flatness apparent from the beautiful reflection.

Typically, extra-wide or extra-large mirror polished stainless steel panels are provided in thicker sheets with cut-edge panel details, to ensure the high-quality of the finish. The difficulty comes from the quality of the metal sheet material, as sheets over 2mm tend to have pores, and this tendency increases with larger sized sheets. Additionally, larger panels are proportionally heavier, requiring more time, people and care during handling.

At Kikukawa, these difficulties have been addressed, overcome and accumulated as know-how. We share our quality control expertise with the material providers and the polishers to ensure the high-quality of the panels.

Rough-tone Metal, P Series

Rough-tone metal is Kikukawa’s proprietary embossing technology, which implements cast-like textures. The produced panels are low in cost, light in weight, versatile in function and provide the stately aesthetics of metal.

Kikukawa’s rough-tone metal is offered in two series: P and R. The P series is a collection of sharp embossing and deep-drawn patterns, while the R series is a collection of roll embossing patterns implemented with proprietary machinery and dies. These patterns are suitable for a variety of occasions as both interiors and exteriors.

Here, we introduce 2mm black aluminium exterior panels, decorated with rough-tone, P series, KU-P513. This abbreviation stands for 12mm wide and 74mm long oval patterns.

Minimal Distortion And High Strength Welding Brass

Brass is a popular material for interior use, for its chic gold texture and high workability.

Kikukawa is able to weld extra-long and 3 dimensionally curved panels with minimal distortion.

Here is a perforated brass metal product over the market available material sheet size. Finished with hair-line and clear coating, a texture that fully displays the beauty of brass.

Perforated brass panel, welded vertically between the second and third perforation from the bottom left corner.

Perforated brass panel, welded vertically between the second and third perforation from the bottom left corner.

To satisfy the requirements, welded brass metal sheets with high strength, minimal distortion and minimal discolouration were necessary.

While the final product size is 2140mm (W) x 1604mm (L), the largest market available sheet is 1250mm (W) x  3050mm (L). To ensure the necessary strength for perforation with typical welding methodology (TIG welding) would have required careful welding – and the carefully TIG welded sheets would have suffered from discolouration and distortion from the heat.

Kikukawa overcame this difficulty by combining the latest welding technology and craftsmanship.

Welding Brass Without Discolouration

Kikukawa has developed a new technology to weld brass without discolouration.

Previously, Kikukawa was able to minimize discolouration by refining its welding technology, however, it was near impossible to remove it. With this new technology, we are able to fabricate over-sized brass panels or weld extrusions without discolouration.

Two brass samples, welded at the center. Left: New welding technology Right: TIG welding. As the picture shows, discolouration can only be observed from TIG welded sample.

Two brass samples, welded at the center. Left: New welding technology. Right: TIG welding. As the picture shows, discolouration can only be observed from TIG welded sample.

Brass is a widely used material in architecture, as door handles, handrails, faucets, signboards and others. From the gold hue of new brass to the rich brown hues of patinated brass, the changing colour is part of the material’s appeal.

However, it has not been a common choice in larger products for various reasons.

For instance, casting, extruding or machining brass to the necessary quality meant longer fabrication lead time and higher costs.

To combat discolouration from welding brass, brazing was used for products that required less welding strength. However, brazing requires experience and the filler material lead to slight discolourations.

With the new technology developed by Kikukawa, we overcame these difficulties so that fabrications of larger products or products that hope to utilize the original texture and hues of brass are possible. Furthermore, as the material is not exposed to discolouration, finishes such as sulfurization are also possible.

Machining Brass

Metalworking brass comes with its own challenges. The characteristics of brass make certain shapes difficult to manufacture – welding would lead to decolourisation, and extruding or die-casting would involve costly and lengthy die fabrication process.

Machining brass is one way to overcome these problems. At Kikukawa, we are able to accommodate the production of larger three-dimensional shapes in small lots.

From the 3D CAD design data, our machine metalworks brass pieces with high precision. The maximum workable size is 2500mm(W) x 3500mm(L) x 400mm(H), and the workable materials include aluminium, stainless steel, bronze alloys, and wood.

Honeycomb Backed Curved Bronze Panels

Honeycomb backing curved bronze panels is Kikukawa’s proprietary metalworking technology that stems from honeycomb backing stainless or aluminium panels.

When consulted to fabricate bronze balustrade panels over 2m in width, Kikukawa developed and solidified two technologies – honeycomb backed bronze copper alloys and honeycomb backed curved panels. The resulting panel has high strength and the honeycomb backing upholds the panel’s flatness and curvature.

Honeycomb backing curved panels are applicable to other materials.

Stretch Forming

Fabrication of bespoke items comes with its own challenges – R bending complex shaped products is one example.

Typically, R bending corrugated parts requires welding pieces, which tends to compromise the aesthetics, consume time and add to the fabrication cost.

Stretch forming overcomes these difficulties. The produced products are stretched into shape, thus eliminating the need for welding.

Fabrication of “Hounou-date”

Every year, KIKUKAWA fabricates pentagon shields, “Hounou-date”, to pray for safety and prosperity in the upcoming year and to exemplify our New Year’s resolution. On the shield, there are three objects that denote the Japanese Kanji character for water, 水. Each object symbolizes our prayer: the “sword” to ward off evil, the “sickle” to bring good harvest, and the “key” for prosperity.

The root of this tradition lies with Japanese blacksmiths fabricating “Hounou-date” as a talisman against fire. By dedicating a shield with a water kanji at the beginning of the year, the craftsmen cleansed their workplace and prayed for another safe year.

KIKUKAWA still honours this practice as a sign of respect for the artisan handiwork. To hone and pass on our craftsmanship, the fabrication of the shield is carried out by younger members and Vietnamese trainees.

As per tradition, three key materials and finishes were chosen.

  • FURUMI(sulfurized) bronze with the water kanji in silky blasted stainless steel
  • -Anodized and defined vibration finished aluminium with the water kanji in silky blasted stainless steel
  • -Both shield and the water kanji in stainless steel with coloured clear coating

Official Launch of an Industry-Academia-Government Collaboration Research Project

KIKUKAWA is announcing the official launch of a metalworking research project in collaboration with METI (Kanto Bureau of Economy, Trade, and Industry, a regional branch of Ministry of Economy, Trade, and Industry) and Fukui University.

< De Beers Ginza Building: Exterior Stainless Steel Panels fabricated with 3D Metal Forming Technology >

This launch comes in response to the confirmation of the receipt of a government grant offered by SME (Organization for Small and Medium Enterprises and Regional Innovation, JAPAN) that is overseen by the Japanese Ministry of Economy, Trade, and Industry and partly under co-jurisdiction with the Japanese Ministry of Finance.

Since 2011, KIKUKAWA has been researching for ways to ease the fabrication process of double curved panels. This was in response to the increasing demand to fabricate double curved products in a more efficient manner as the international architectural designs have become more complex with the development of 3D CADs.

One of the difficulties with 3D metal forming is that it traditionally requires 6~10 times more manufacturing lead-time and cost than its counterpart, the 2D panels, as fabrication relies on a seasoned metalwork expert and/or press forging with dies.

This research hopes to establish an automated die-less 3D metal forming technology that could fabricate a wide variety of small lot custom-made large sized metal products. This innovative research, said to be the first of its kind ran by a bespoke architectural metalwork provider, is planned to be completed in 2019.

[Louver System] Patent Obtained to Develop an Innovative Louver

On December 12th 2016, KIKUKAWA obtained a Japanese patent for the invention of a new “Louver System.”

Patent Overview:

-Name: Louver System

-Patent Number: 6061781

-Date of Receipt: 2016/12/22

Summary of the Invention:

-Reduces heat gain while allowing efficient control of natural light

-Reduces operating energy use and running cost of the building

-Designed to be both stylish and practical

-KIKUKAWA’s Louver System-

There is a growing environmental awareness in today’s world. In architecture, the responsibility to create more green and sustainable buildings is gaining momentum for architects and building owners.

Given this, KIKUKAWA worked with Dr. Jürgen Koch to invent a movable louver system, innovative in design and function that could be installed for new and existing projects.

-The Kochs-

One of the ways to increase the energy efficiency of a building is to install louvers outside of the windows. This is where the buildings are susceptible to the effects of incoming heat gain and sunlight. The exterior louvers could help control this before it enters the building thereby increasing the energy efficiency as well as reducing the installation and the running cost of the building.

Other existing louvers were able to control sunlight and heat gain; however it was not able to concurrently allow natural light to fill the room. With existing models, the building would be more energy efficient and the AC costs would be reduced, but the lighting costs would not be affected. KIKUKAWA’s new louver system addresses this problem. The design of the new system differs at the top and bottom and because both parts are movable, it allows heat gain reduction as well as efficient sunlight control depending on the intensity of insulation and the location of the sun.

KIKUKAWA is currently working on merchandising this invention. Please inquire for more details. KIKUKAWA will continue to invent and provide high-quality and high-value environmental products.

Fabrication of “Hounou-date”

Every year, KIKUKAWA fabricates pentagon shields, “Hounou-date”, to pray for the safety and prosperity in the upcoming year and to exemplify our New Year’s resolution. On the shield, there are three objects that denote the Japanese Kanji character for water, 水. Each object symbolizes our prayer: the “sword” to ward off evil, the “sickle” to bring good harvest, and the “key” for prosperity.

The root of this tradition lies with Japanese blacksmiths fabricating “Hounou-date” as a talisman against fire. By dedicating a shield with a water kanji at the beginning of the year, the craftsmen cleansed their workplace and prayed for another safe year.

KIKUKAWA still honours this practice as a sign of respect for artisan handiwork. To hone and pass on our craftsmanship, the fabrication of the shield is carried out by younger members and Vietnamese trainees. The chosen materials and finishes are those that were most commonly used or that became the topic of conversation as a reminder of our company’s founding principles and spirit.

This year, three shields were fabricated.

  • Sulfurized bronze with the water kanji in mirror polished stainless steel
  • Sulfurized bronze with the water kanji in mirror polished then Silky blasted stainless steel
  • -Bright dip anodized Aluminium with the water kanji in hairline or vibration finish

 

Hounou-date

 

The sulfurized bronze finish is a classic in Japanese architecture, but is increasingly becoming popular overseas. Our most recent project was Shiki-Juraku, a Kyo-machiya style hotel.

The bright dip anodized Aluminium is a highly reflective finish that emulates the sheen of stainless steel. The Sumida Hokusai Museum drew attention last year as the first architectural project in Japan to employ this material as an exterior.

These shields are displayed on the walls of our factory. Please take a look should you ever have a chance to pay a visit.
