  <h2>Rebuilding 2 km of MIDC industrial road at Ambarnath West</h2>
  <p class="ck-lead">The stretch between the CNG pump and Forest Naka carries loaded tankers and container traffic for a dozen chemical, polymer and pharmaceutical plants. Civikor surveyed the full 2,016 m corridor, designed it as three width-graded packages, and detailed a rigid pavement built for industrial axle loads rather than city traffic.</p>

  <h3>The brief</h3>
  <p>MIDC Ambarnath West is a working industrial estate, not a planned business park. Its internal roads front Robonik India, Sulzer Pumps India, Arabian Petroleum, Brilliant Polymers, Centaur Pharmaceuticals, Aashish Colors, Arkap Knits, Manisha Industries, Aditya Industries and a Mahanagar Gas CNG station — every one of them running tankers, tippers and container movements across the same surface.</p>
  <p>Under that loading a bituminous pavement fails quickly, and it fails worst at the plant gates where vehicles turn and stand. Ambarnath Municipal Council needed the sector rebuilt in concrete, with a section designed for the actual traffic and a drainage and duct layout that would not need the new slab cut open six months later.</p>

<section class="ck-block">
  <h3>Scope of work</h3>
  <ul class="ck-list">
    <li><strong>Corridor survey (December 2024)</strong> — 2,016.28 m of industrial road recorded with existing drains, fire hydrants and utility positions.</li>
    <li><strong>Width classification</strong> — the corridor split into 18 m, 15 m, 12 m and 9 m classes so each link gets the section its frontage and turning movements actually require, instead of a single width applied across the sector.</li>
    <li><strong>Road estimate (RE) sheets 1–3</strong> — plan, longitudinal section and quantities, chainage-referenced across the full length.</li>
    <li><strong>Typical cross-sections</strong> for each width class, covering carriageway, footpath, kerb and drain.</li>
    <li><strong>Cross duct and trial pit details</strong> — subsurface strata logged and service crossings positioned before construction.</li>
    <li><strong>Gate-wise location plans</strong> — separate location and Google location plans issued for the Aditya Snacks, Arabian Petroleum and Green Chilli Dhaba stretches, each naming the industrial units it fronts.</li>
    <li><strong>Project management consultancy</strong> through execution.</li>
  </ul>

<section class="ck-block">
  <h3>Pavement specification</h3>
  <p>Typical 18.00 m section — 1.50 m footpath + 2.00 m side strip + 5.50 m carriageway + 5.50 m carriageway + 2.00 m side strip + 1.50 m footpath, at 2% camber.</p>

  <p class="ck-note">Kerb stone with water table to both edges. The 12.00 m section follows the same build-up at 1.50 + 1.50 + 3.00 + 3.00 + 1.50 + 1.50 m.</p>

  <h3>How we approached it</h3>
  <h4>Trial pits before design, not during construction</h4>
  <p>Trial pits were sunk along the corridor and the strata logged — silt, clay and pebbles over soft murum. Knowing the subgrade before finalising the section is what allows a 0.23 m soling and twin granular sub-base to be specified with confidence, instead of discovering the problem after the DLC is placed.</p>

  <h4>Chainage-referenced service crossings</h4>
  <p>Existing drains and utility crossings were fixed by chainage across the corridor — at 30–40 m, 90 m, 110 m, 170–180 m, 230 m, 320 m, 510 m, 560 m, 840 m and 880 m on the main 18 m link alone. Every one of them is a decision point on a rigid pavement, and every one is resolved on the drawing rather than on site.</p>

  <h4>Width matched to frontage</h4>
  <p>Four width classes across one sector is deliberate. The main link to the dumping road takes 18 m because it carries the estate's through traffic; the Green Chilli Dhaba stretch takes 9 m because widening it further would only consume industrial plot area for no operational gain. Sizing each link separately kept scope proportionate to use.</p>

  <h4>Designed to stay uncut</h4>
  <p>Cross ducts at 0.30 m dia are cast in during construction at every anticipated crossing. On an industrial estate where new plants connect utilities every year, this is the single decision that protects a 30-year concrete pavement from being trenched in year two.</p>

<section class="ck-block">
  <h3>Why it matters</h3>
  <ul class="ck-list ck-list--tick">
    <li><strong>Built for industrial loading.</strong> M40 pavement quality concrete over DLC carries the tanker and container traffic these plants actually run — where a bituminous surface would rut and shove within a season.</li>
    <li><strong>Two kilometres treated as one asset.</strong> Continuous levels, drainage falls and duct positions across all three packages, rather than three roads that meet awkwardly at their joints.</li>
    <li><strong>Predictable access for eleven industrial units.</strong> Named gate-wise plans mean each occupier could see and sign off on its own frontage before work began.</li>
    <li><strong>Drainage that survives the monsoon.</strong> Covered RCC side drains on a raft foundation, sized to keep an industrial corridor operating through Konkan rainfall.</li>
    <li><strong>Low whole-life cost.</strong> Rigid pavement with pre-installed crossings shifts spending from recurring repair to a one-time asset.</li>
  </ul>

  ================= AUDIT NOTE — REMOVE BEFORE PUBLISHING =================
  1. The page currently live shows only ONE of the three packages (Aditya Snacks, 1100 m ×
     18 m). The other two links are in the shared files and roughly double the project size.
  2. Length reconciliation to confirm with Crystal Technical Consultant:
       Location plans total     1,100 + 275 + 710 = 2,085.00 m
       RE sheets total          1,059.25 + 430 + 260 + 247.28 = 1,996.53 m
       Survey plan states                                        2,016.28 m
     Three different totals. The 2,016.28 m figure used above is the survey plan's.
  3. The Green Chilli Dhaba link is described as 710 m × 9.00 m on its location plan, but
     RE sheet 2 splits the same stretch into 430 m at 15.00 m and 260 m at 9.00 m.
     The 15 m class does not appear on any location plan. Confirm before publishing widths.
