Create cube

Add resolution using connect, pinch + inset

Select polygon + indent as shown below

Select roof - extrude - 

Add geometry along roof using connect

Manipulate vertex to create curved roof

Creating roof inside

Create cube - change dimensions to slim cuboid - array for depth

Select all duplicates - tools - array - second direction

Create connecting beam (cube stretched) array in two directions at once (to connect all components of inside roof)

Third connection slopes to towards centre therefore requires two directional array to mid point

Then mirrored to complete

Move into position

Attempt 2

Walls - features

Create gengon - 6 sided - to taper

Clone and place into pattern as shown

Connect gengon's using bridge (select opposing polygons, bridge tool)

Extrude further as shown

Attempt 3

Before connecting using bridge - inset every side to give extra detail to joining parts

Extrude and connect as shown (shown next to previous attempt

Place onto wall - extend horizontal  shafts - add extra cubes (cuboids) for detail

Replicate main feature of wall to add detail

Mirror to cover opposing wall

Back wall - cubes - stretched - inset one side - move ploygon in for indent as shown below - pair with clone - replicate across the back wall

detach roof - clone - place next to original

Select outside wall - extrude to line with roof

Crane

Create gengon -  6 sided - no taper - select bottom face - inset - extrude + repeat 5x

Create cage using same technique as cage for truck roof

Cube - inset all sides - remove unneeded polygons - bridge created gaps

Truck Improvements

Grill

Select polygons on front of vehicle - remove to create hole - manipulate vertex to create accurate boarder

use msmooth to generate more accurate profile. - select boarder - hold shift pull inwards - generate geometry for inside of grill

Create cube - change settings to generate strip - rotate to generate appropriate angle.

tools - array - create vertical array many elements in vertical direction

Add splitters (cube - narrow strip - place as appropriate)

Light casings

Create cube - 2 segments (shaft)

Select both side polygons - inset , by polygon - move polygons inwards to create hollow case

Manipulate shape and move into position

Hide front hood part of car - select inside side casing geometry's - delete - this leaves a border around floating back inside casing polygon + inside edge of front of component of each hollowing - select inside edge of front of component

 Cap - detach - extrude - move away (in single plane) away from casing

Select inside boarders - bridge to replace previously deleted geometry

Unhide truck components

Manipulate casing to fit onto truck correctly

Symmetry to create duplicate for alternate side of vehicle

Cage to hold lights on roof

select roof polygon - inset - select created boarder - extrude

Select outside centre polygons - delete

Bridge open edges to re seal geometry

Main spinning lights 

Cone - top diameter greater than lower - select top polygon - inset - extrude - inset - select boarder - extrude

Delete boarder

select inside boarder - cap

select outside boarder - cap

Turbo smooth

Simple objects - cylinder

Select polygons around base of shaft - delete

Edge ''tool / selector'' - hold shift - drag outwards horizontally - repeat vertically - repeat for base

Select top + bottom edge of flat side - connect - connect options (side box) - slide + pinch 2 segments

Repeat for opposite side + to add shown below geometry

Select polygon - inset

inset again then move backwards to create indent - curves created by manipulating earlier added resolution / geometry

Remove top to polygons along shaft - cap - select capped polygon surface

Extrude vertically

Select end polygon + extrude

Select cylindrer + newly created bar - detach

Select all other geometry (rear base) - mirror / symmetry - create mirrored entity

Place apprpriately

Select opposite edges as shown below - bridge

Re-attach all geometry together - target weld loose vertex to remove gaps / overlaps

select cylinder end polygon - extrude - select end border + cap to create back face

CAB ATTEMPT 1

Create box - many segments

Manipulate vertex to create truck front shape as shown below

Extrude to half width of cab

CAB ATTEMPT 2

Create tube - select outside edge vertex - move backwards to create sloped angle - remove unwanted segments to create arch

Select - boarder - cap bottom of arch

Select back edge - hold shift - move vertically - adjust vertex positions to create bonnet shape - hold shift pull horizontally

Select vertical edge to pull out door base - separately select bonnet edge and pull out (hold shift + move) to create windscreen and roof

To create boarder for side window loose geometry needs to be tied together to form closed boarder to be capped. Target weld vertex together below is a before shot

After shot

Polygon select all geometry as shown below - detach

Select front - turbo smooth

Mirror / symmetry to create full front cab - attach new segment to orginial

Remove two segments creating windscreen - target weld geometry to create boarder

Cap boarders

Wheels

Create tube (many segments) - manipulate vertex to give rounded, softer appearance

Create cylinder with minimum 5 cap segments

Manipulate segment radii to allow narrow wide narrow config - select wide section ring using polygon select - move backwards to create indent

Clone wheel and tyre to create back wheel - mirror / symmetry both wheels too create wheels for otherside

Create three cylinders, two sizes - configure as shown below - put together to create exhaust- align with side of vehicle 

Underside of vehicle has no geometry - select front edge + back edge - bridge

Result of bridge

Basic render check

Wide angle mirror - create cone - on large cap select polygon - inset - move geometry inwards 

Create cube - select one shaft side - polygon - inset - move polygon inwards

Position accordingly

Create cube - many segments - select modifier bend - set angle

Move into position to create illusion of support

Attach and bridge to mirror - ad straight supports to long mirror - use simple cuboids

Materials

Create colour bitmaps + logo bitmaps + metals + rubber

Use raytrace maps on reflect + refract to create glass

Select all cylinder geometry - detatch

Select top edge of side + bottom - connect - 2 segments - pinch

Select polygons as shown

Apply bitmap/material logo to section - scale + move until desired outcome.

Apply mirrored + reversed logo to opposite side (with placement manipulation rotation may be required)

Apply all other materials
