About BUILD EMPIRE: Construction
From a small local builder to the largest contractor in the world.
BUILD EMPIRE is a turn-based management simulation about running a general contractor. Win work in the bid room, run the sites, grow the company, and climb to No.1 in the world rankings.
■ How it plays
1. Bid - price the job and win the contract
2. Build - advance the month, progress the work, collect payment
3. Manage - grow departments, hire people, raise finance
4. Rank up - build a track record, clear the stage requirements, reach the top
■ Features
- Fully turn-based. Nothing moves until you press "Next month". No timers, no waiting.
- Projects from detached houses to skyscrapers, airports and maglev lines, up to national megaprojects and space-scale works
- Every project type has its own rendering, so you can see what you are about to build
- Sites change as the work progresses: cleared ground, excavation, foundations, steel frame, cladding, completion. Bridges, tunnels and offshore wind each build in their own way.
- Bidding tactics driven by technical score, standing, sales strength and your relationship with the client
- Choose how your people work. Closing the site two days a week costs money and time, but morale and retention rise, and you avoid the overtime breaches that end in debarment from public bidding.
- Payroll is not just salary. The employer's share of health, pension, unemployment and workers' compensation insurance falls due every month, and the workers' comp rate rises after an accident and falls when you invest in safety, exactly as the merit system works
- Department levels, hiring and staff traits, bank finance, investment projects, M&A and overseas expansion
- Everything you finish stays in the city on the home screen, built as itself - your own skyline takes shape.
- Name your own developments and hold them: rent comes in every month, for as long as you own them.
- A completion report every month. The real test is how far you beat your planned profit.
- World rankings by revenue, profit and technical score
■ For players who
- New to this? Five cards explain what you can do when you start, and the home screen tells you your next step.
- Enjoy management sims with real numbers behind them
- Are interested in construction and city building
- Want a game they can move forward one month at a time
■ Pricing
Free to play all the way through, with a banner ad.
The one-time Premium (deep management) purchase removes ads and opens up:
- Subcontractors - build your trade base, sign exclusive partners, negotiate rates and payment terms
- Superintendents - grow them on site, post a job ad to hire in, and reassign them all in one go
- Pay and benefits - set monthly pay and bonus months per grade, then design nine benefit programmes (company housing, rent subsidy, away postings, site allowance, licence support, family allowance, occupational health, an employee share plan and retirement pay) as unit price x people covered. How many people qualify moves with you

■ 給与を数字で入力できるようになりました
「課金したが、従業員の給与が増減できない」というご意見をいただきました。1.7 では等級別の月給の −/+ を押しても画面の数字が変わらず(1.8 で直しました)、さらに1回押しても1万円ずつしか動かないため、昇格で上がった相場まで戻すのに何十回も押す必要がありました。
プレミアムの給与の画面で、係員・主任・課長・部長の月給を万円単位で直接入力できるようにしました(18万〜300万円)。−/+ も今までどおり使えます。
あわせて、全等級の月給を比率を保ったまま ±1%・±5% で動かすボタンを足しました。また、昇格して同格の相場が上がり、給与が相場を下回ったときは、昇格の画面で知らせて「給与を見直す」から直接開けるようにしました。
■ 超難関の立ち上がりを見直しました
「超難関で最初に2〜3件取ると、着手金や人件費ですぐ倒産してしまう。最適な開始資金を調べてほしい」というご意見をいただきました。7,000回以上の試算で調べたところ、開始資金を増やすだけでは倒産は減らず、原因は2つありました。
・最初に受注した翌月、工事代金の入金が1ヶ月遅れるだけなのに「資金ショートが近い」という警告と出ていました(超難関で86%)。この警告は「この月のまま続いたら」の収支で判定するようにし、着工直後の一時的な持ち出しは「⏳ 着工直後の持ち出し」として、来月の入金予定と一緒に案内します。
・受注が途切れても、4月の新卒で人が増え続けていました。会社の立ち上がり(STAGE2まで・竣工24件まで)は、受注残に見合う人数だけ新卒を採るようにしました。
あわせて、超難関の開始資金を0.9億円から1.2億円にしました。最初に3件取って月を進めた場合の3年以内の倒産は、試算で66%から2%になりました。
■ 銀行と資金繰りを見直しました(新しく始めた会社から)
「借り換えを繰り返せば、まったく倒産しない」というご意見をいただきました。
・当座借越に極度額(年商と純資産で決まる上限)を設けました。超えると知らせ、翌月の締めでも超えていれば資金ショートで倒産します。
・銀行は他行の借入も見て貸すようにしました。借り換えはできますが、3行合わせた総枠を超えては借りられません。
遊んでいる途中の会社に急な倒産が起きないよう、極度額と資金ショートはこの更新のあとに始めた会社から効きます。
■ 投資開発に50兆円・200兆円規模の案件
「残金を全部投資したいのに、毎度数兆円しかできない」というご意見をいただきました。投資開発部 Lv21 から〜50兆円、Lv25 から〜200兆円の案件が出るようにしました。大型の帯には新しい種類「宇宙・都市」(宇宙太陽光発電所・海上都市・月面基地などの運営)が加わります。
■ 世界1位のあと、ライバルが追い上げてきます
「1位になったら無心のポチポチゲー」というご意見をいただきました。世界1位に着いたあとは、上位の有力ライバル3社が毎年差を詰めてきます。伸び続ければ首位を守れ、止まると抜き返されます。強さは難易度で変わります。
■ そのほか
・メニューの「アプリ」にプライバシーポリシーを足しました(ブラウザで開きます)
・世界ランキングで、長い社名が「…」で切れていたのを2行まで折り返して読めるようにしました
・更新内容の版のタブで「ver 1.8最新」と文字が詰まって見えていたのを直しました

■ Org chart
A player told us that the deeper the hierarchy — sections under departments, heads of each division, vice presidents — the more immersive the game feels.
People now has an Org/Execs tab. Under the president sit the Building, Civil Engineering, Development, Administration and Technology divisions, with departments, sections and groups below them. Alongside head office, branches are listed from north to south (overseas bases are grouped into one International Branch, with a group for each region), and every active job appears as a site office under a works section, with its site manager. Administration includes Corporate Planning, and the Building Division has a Safety & Quality department. The chart grows as your company grows.
Tap "View the full org chart" to open a boxes-and-lines chart full screen, with headcounts and the names of division heads and general managers. Pinch to zoom and drag to move.
■ Sections
Each time a department reaches Lv 5, 15, 25, 35, 45 and 50, you can set up one more section — fully grown, it has every section. Choices include Public Sector Sales, Works Administration, Safety & Environment, Quality Control, Legal & Compliance, Public Relations, Renewable Energy, the Environment Lab and more. Each department has its own choices, each with a small effect. Building Construction starts with a building works section and Design with an architectural design department; as they grow, an MEP works section and structural and MEP design departments appear on their own. Civil Design splits into Bridge, Tunnel and Geotechnical Design too.
■ Executives
As your company moves up the stages, seats open for directors, managing directors, senior managing directors and vice presidents. Executives head a division and boost its departments.
Each March, at year-end, a candidate is put forward from your department general managers. Terms are two years, and you set the executive pay level.
Every department has a named general manager, and you can pick a new one from the section managers once a year.
■ Executive scandals
Once in a while, a whistleblower report about an executive arrives. An internal investigation usually settles it before it goes public. If it hits the news, you choose whether to apologize and dismiss them or stand by them. "Forceful" executives give a bigger boost, but carry a bigger risk.
■ President's name
Set it when you start a company, or at the top of the org chart.
■ With Premium
Set pay for each executive, rename divisions, departments and sections, and choose executives from three candidates.
■ Faster Sites tab
A player reported that the Sites screen took about 5 seconds to open once they had many projects. We now do the heavy counting once and show 30 cards at a time (tap Show more for the rest). Even with 200 sites, it opens right away.
■ Also
・The Construction department has a new name in the Japanese version (nothing else changes)
・Fixed the People screen in English showing morale and turnover in the wrong places
・Fixed the grade pay and bonus −/+ buttons on the Pay screen not updating the numbers
・Saving now writes to your device far less often, which is easier on battery and storage

■ 受注後VEが入りました
着工した現場から、同じ性能を保ったまま工事原価を下げる提案(VE提案)が上がってきます。杭の工法、躯体のプレキャスト化、外部足場、熱源方式など24種類。施工タブの先頭に溜まるので、月送りが止まることはありません。まとめて出すこともできます。
検討費は提案した月に出ていき、採用されなくても戻りません。採用されると残りの工期のあいだ毎月の原価が下がり、効果金額の一部を施主へ還元します。効くのはまだ施工していないぶんだけで、進捗35%を過ぎると出せなくなります。
施工部・設計部・技術研究所を育てるほど提案が上がりやすく、大きく削れます。
■ 世界のプレイヤーと競えるようになりました
Apple の Game Center で、実際に遊んでいる人と記録を比べられます。世界ランキングの画面の「世界のプレイヤーと競う」から開けます。
記録は年間売上・年間利益・総資産・社員数・時価総額・STAGE6到達の速さの6つ。難易度ごと(ふつう・むずかしい・超難関)に分かれています。時価総額はプレミアム限定です。
Apple ID でサインインするだけで、アカウント登録は要りません。サインインしなくても、ゲームはこれまでどおり遊べます。
■ 副所長をまとめて付けられます
「副所長の担当を決めるのに時間がかかる。一括で空いている現場に振れたら」というご意見をいただきました。現場タブと人事の所長タブに「副所長をまとめて付ける」を置いています。大きい現場から順に、手の空いた所長を付けます。
■ 超難関の立ち上がりを調整しました
「むずかしいはクリアできたが、超難関は一気に難しくなって何もできない」というご意見をいただきました。超難関は、最初の竣工8件までは原価の厳しさを「むずかしい」と同じにし、竣工24件にかけて元の厳しさへ戻します。開始資金・悪い出来事・昇格の条件・ライバルの強さはそのままです。
■ 判断の材料を増やしました
・現場カードの「原価が動いた理由」で、見込原価が積算からどう動いたか(所長の不在・兼務、協力会社、閉所、VE など)を円で確かめられます
・「次の月へ」を押したとき、所長不在や賞与不足などの注意があれば確認の中に出ます。押すとその画面へ移ります
・入札の案件に「検討中」の印を付け、絞り込めます
・繰上返済の額を選べるようになりました
・施主・取引先の一覧に海外の施主も並びます
■ 直した不具合
・アプリを入れ直したり機種を変えたりしたとき、プレミアムが自動で戻らないことがありました(1.6から)。「購入を復元」を押さなくても戻るように直しました
・業績予想・所長を替える・副所長を選ぶの画面で、文字が重なって読めないところがありました
・まとめて応札の予算を「全部落札したときの初月の支出」で測るようにしました。以前は請負金額の合計で測っていたため、応札できる額が小さくなりすぎていました
・「次の月へ」が効かなくなりうる箇所を洗い直して、つまずいても進めるようにしました
■ 細かな改善
・画面の小見出しを白い太字にして、見つけやすくしました
・画面上部の資金を「1京2212兆1111億円」のように細かく出すようにしました
・「10,000兆円」のように、単位が上がるべきところで上がっていなかったのを直しました
・起動時のお知らせは直近3つの版だけにし、メニューの「更新履歴」からは過去の版をすべて選べます
・世界ランキングのタブは、開くと一番上から表示します
・月送りで一度つまずいてやり直したとき、その月の報告から検討費などが抜けることがあったのを直しました
